So, I am setting the DataSource of my BindingSource to the DefaultViewManager of a DataSet that has a DataRelation. I then set my BindingSource as the UltraGrid's DataSource before applying a RowFilter to the the "SalesOrderSublines" DataView.
public void RefreshData()
{
var dataset = DataService.GetMillWorkOrders()
bindingSource1.DataSource = dataset.DefaultViewManager;
ultraGridSequences.SetDataBinding(bindingSource1, "", true, true);
var dvm = bindingSource1.DataSource as DataViewManager;
dvm.DataViewSettings["SalesOrderSublines"].RowFilter = "LINE_NO = 2;
}
public static DataSet GetMillWorkOrders()
{
DataSet ds = OracleHelper.ExecuteDataset(_connectionString, CommandType.StoredProcedure, SQL.GET_WORK_ORDERS);
ds.Tables[0].TableName = "WorkOrders";
ds.Tables[1].TableName = "SalesOrderSublines";
var dr = new DataRelation("WorkOrderSublines", ds.Tables["WorkOrders"].Columns["WORK_ORDER"], ds.Tables["SalesOrderSublines"].Columns["WORK_ORDER"]);
ds.Relations.Add(dr);
return ds;
}
Then, as the UltraGridRows are initializing I want to hide any parent row ("WorkOrders") that has no visible child rows ("WorkOrderSublines") because of my RowFilter.
private void ultraGridSequences_InitializeRow(object sender, Infragistics.Win.UltraWinGrid.InitializeRowEventArgs e)
{
if (e.Row.Band.Key != "WorkOrders") return;
e.Row.Hidden = e.Row.ChildBands["WorkOrderSublines"].Rows.VisibleRowCount == 0;
}
Although the RowFilter does work properly on the rows in the "WorkOrderSublines" band the VisibleRowCount of the band is still greater than zero and so the parent row is never hidden. My guess is that I want to look for something other than the VisibleRowCount of the ChildBand to determine if the top-level row should be hidden, but I'm stuck. Any help would be greatly appreciated. Thanks ahead of time.
Instead of relying on VisibleRowCount you could simply compare the count of child row filtered vs total count.
void ultraGridSequences_InitializeRow(object sender, Infragistics.Win.UltraWinGrid.InitializeRowEventArgs e)
{
if (e.Row.Band.Key != "WorkOrders") return;
var sublinesBand = e.Row.ChildBands["WorkOrderSublines"]
e.Row.Hidden = sublinesBand.Rows.Count(row => row.IsFilteredOut) ==
sublinesBand.Rows.Count();
}
Should be fine performance-wise so long as we're not talking huge amounts of records?
Using the Filtering within the Grid may be an option rather than using the filtering in the DataSource. The following resources have more details on implementing this:

When I try to insert image directly to the ImageFieldMergingArgs it appears properly in the table cell using the following code...
override fun imageFieldMerging(imageFieldMergingArgs: ImageFieldMergingArgs) {
val fieldValue = imageFieldMergingArgs.fieldValue
if (fieldValue is DataString) {
val decodedImage = fieldValue.decode()
imageFieldMergingArgs.imageStream = ByteArrayInputStream(decodedImage)
}
}
But when I'm trying to insert an image using Shape in MailMerge. then it is appearing outside the table. I'm using the following code
override fun imageFieldMerging(imageFieldMergingArgs: ImageFieldMergingArgs) {
val fieldValue = imageFieldMergingArgs.fieldValue
if (fieldValue is DataString) {
val shape = Shape(imageFieldMergingArgs.document, ShapeType.IMAGE)
shape.wrapType = WrapType.SQUARE
shape.aspectRatioLocked = false
shape.anchorLocked = true
shape.allowOverlap = false
shape.width = imageFieldMergingArgs.imageWidth.value
shape.height = imageFieldMergingArgs.imageHeight.value
imageFieldMergingArgs.shape = shape
}
}
is there any way I can add an image into the table cell using shape to imageFieldMergingArgs.
Thanks
When you specify imageFieldMergingArgs.imageStream the shape is inserted with WrapType.INLINE. In you second snippet you specify WrapType.SQUARE. This might be the difference. It is difficult to say exactly what is wrong without your template. But I would try specifying WrapType.INLINE. I tested both your code snippets on my side with a simple template an in both cases the image is inside table cell.
Please look at this case:
if (product.ProductId == 0)
{
product.CreateDate = DateTime.UtcNow;
product.EditDate = DateTime.UtcNow;
context.Products.Add(product);
if (!string.IsNullOrEmpty(product.ProductValueProduct)) { SaveProductValueProduct(product); }
}
context.SaveChanges();
When I debug code the ProductId is negative, but afer save the ProductId is corect in database (I know this is normal), but when I want to use it here: SaveProductValueProduct(product) after add to context.Products.Add(product); ProductId behaves strangely. (I'm creating List inside SaveProductValueProduct)
List<ProductValueProductHelper> pvpListToSave = new List<ProductValueProductHelper>();
foreach (var item in dProductValueToSave)
{
ProductValueProductHelper pvp = new ProductValueProductHelper();
pvp.ProductId = (item.Value.HasValue ? item.Value : product.ProductId).GetValueOrDefault();
pvp.ValueId = Convert.ToInt32(item.Key.Remove(item.Key.IndexOf(",")));
pvp.ParentProductId = (item.Value.HasValue ? product.ProductId : item.Value);
pvpListToSave.Add(pvp);
}
I want to use ProductId for relationship. Depends on logic I have to save ProductId at ProductId column OR ProductId at ParentProductId column.
The ProductId 45 save corent at ProductId column (3rd row - this is a relationship), BUT not at ParentProductId (2nd row - this is just null able int column for app logic), although while debug I pass the same negative value from product.ProductId there.
QUESTION:
how can I pass correct ProductId to column that it isn't a relationship column
I just use SaveProductValueProduct(product) after SaveChanges (used SaveChanges twice)
if (product.ProductId == 0)
{
product.CreateDate = DateTime.UtcNow;
product.EditDate = DateTime.UtcNow;
context.Products.Add(product);
}
context.SaveChanges();
if (product.ProductId != 0)
{
if (!string.IsNullOrEmpty(product.ProductValueProduct)) { SaveProductValueProduct(product); }
context.SaveChanges();
}
I set this as an answer because it fixes the matter, but I am very curious if there is any other way to solve this problem. I dont like to use context.SaveChanges(); one after another.
i downloaded the last version of iTextSharp dll. I generated a PdfPTable object and i have to set it's height. Despite to set width of PdfPTable, im not able to set height of it. Some authors suggest to use 'setFixedHeight' method. But the last version of iTextSharp.dll has not method as 'setFixedHeight'. It's version is 5.5.2. How can i do it?
Setting a table's height doesn't make sense once you start thinking about it. Or, it makes sense but leaves many questions unanswered or unanswerable. For instance, if you set a two row table to a height of 500, does that mean that each cell get's 250 for a height? What if a large image gets put in the first row, should the table automatically respond by splitting 400/100? Then what about large content in both rows, should it squish those? Each of these scenarios produces different results that make knowing what a table will actually do unreliable. If you look at the HTML spec you'll see that they don't even allow setting a fixed height for tables.
However, there's a simple solution and that's just setting the fixed height of the cells themselves. As long as you aren't using new PdfPCell() you can just set DefaultCell.FixedHeight to whatever you want.
var t = new PdfPTable(2);
t.DefaultCell.FixedHeight = 100f;
t.AddCell("Hello");
t.AddCell("World");
t.AddCell("Hello");
t.AddCell("World");
doc.Add(t);
If you are manually creating cells then you need to set the FixedHeight on each:
var t = new PdfPTable(2);
for(var i=0;i<4;i++){
var c = new PdfPCell(new Phrase("Hello"));
c.FixedHeight = 75f;
t.AddCell(c);
}
doc.Add(t);
However, if you want normal table-ness and must set a fixed height that chops things that don't fit you can also use a ColumnText. I wouldn't recommend this but you might have a case for it. The code below will only show six rows.
var ct = new ColumnText(writer.DirectContent);
ct.SetSimpleColumn(100, 100, 200, 200);
var t = new PdfPTable(2);
for(var i=0;i<100;i++){
t.AddCell(i.ToString());
}
ct.AddElement(t);
ct.Go();
you can use any one of following
cell.MinimumHeight = 20f;
or
cell.FixedHeight = 30f;
The premise is that you have downloaded the jar iText jar,you can try this code,you can achive this function,In a A4 paper out a row of three columns of dataeg:
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import com.lowagie.text.Document;
import com.lowagie.text.DocumentException;
import com.lowagie.text.Paragraph;
import com.lowagie.text.pdf.PdfPCell;
import com.lowagie.text.pdf.PdfPTable;
import com.lowagie.text.pdf.PdfWriter;
public class ceshi {
public static final String DEST = "D:\\fixed_height_cell.pdf";
public static void main(String[] args) throws IOException,
DocumentException {
File file = new File(DEST);
file.getParentFile().mkdirs();
new ceshi().createPdf(DEST);
}
public void createPdf(String dest) throws IOException, DocumentException {
Document document = new Document();
PdfWriter.getInstance(document, new FileOutputStream(dest));
document.open();
PdfPTable table = new PdfPTable(3);// Set a row and the three column of
// A4 paper
table.setWidthPercentage(100);
PdfPCell cell;
for (int r = 1; r <= 2; r++) {// Set display two lines
for (int c = 1; c <= 3; c++) {// Set to display a row of three columns
cell = new PdfPCell();
cell.addElement(new Paragraph("test"));
cell.setFixedHeight(285);// Control the fixed height of each cell
table.addCell(cell);
}
}
document.add(table);
document.close();
}
}
When I have an array of Sitecore IDs, for example TargetIDs from a MultilistField, how can I query the ContentSearchManager to return all the SearchResultItem objects?
I have tried the following which gives an "Only constant arguments is supported." error.
using (var s = Sitecore.ContentSearch.ContentSearchManager.GetIndex("sitecore_master_index").CreateSearchContext())
{
rpt.DataSource = s.GetQueryable<SearchResultItem>().Where(x => f.TargetIDs.Contains(x.ItemId));
rpt.DataBind();
}
I suppose I could build up the Linq query manually with multiple OR queries. Is there a way I can use Sitecore.ContentSearch.Utilities.LinqHelper to build the query for me?
Assuming I got this technique to work, is it worth using it for only, say, 10 items? I'm just starting my first Sitecore 7 project and I have it in mind that I want to use the index as much as possible.
Finally, does the Page Editor support editing fields somehow with a SearchResultItem as the source?
Update 1
I wrote this function which utilises the predicate builder as dunston suggests. I don't know yet if this is actually worth using (instead of Items).
public static List<T> GetSearchResultItemsByIDs<T>(ID[] ids, bool mustHaveUrl = true)
where T : Sitecore.ContentSearch.SearchTypes.SearchResultItem, new()
{
Assert.IsNotNull(ids, "ids");
if (!ids.Any())
{
return new List<T>();
}
using (var s = Sitecore.ContentSearch.ContentSearchManager.GetIndex("sitecore_master_index").CreateSearchContext())
{
var predicate = PredicateBuilder.True<T>();
predicate = ids.Aggregate(predicate, (current, id) => current.Or(p => p.ItemId == id));
var results = s.GetQueryable<T>().Where(predicate).ToDictionary(x => x.ItemId);
var query = from id in ids
let item = results.ContainsKey(id) ? results[id] : null
where item != null && (!mustHaveUrl || item.Url != null)
select item;
return query.ToList();
}
}
It forces the results to be in the same order as supplied in the IDs array, which in my case is important. (If anybody knows a better way of doing this, would love to know).
It also, by default, ensures that the Item has a URL.
My main code then becomes:
var f = (Sitecore.Data.Fields.MultilistField) rootItem.Fields["Main navigation links"];
rpt.DataSource = ContentSearchHelper.GetSearchResultItemsByIDs<SearchResultItem>(f.TargetIDs);
rpt.DataBind();
I'm still curious how the Page Editor copes with SearchResultItem or POCOs in general (my second question), am going to continue researching that now.
Thanks for reading,
Steve
You need to use the predicate builder to create multiple OR queries, or AND queries.
The code below should work.
using (var s = Sitecore.ContentSearch.ContentSearchManager.GetIndex("sitecore_master_index").CreateSearchContext())
{
var predicate = PredicateBuilder.True<SearchResultItem>();
foreach (var targetId in f.Targetids)
{
var tempTargetId = targetId;
predicate = predicate.Or(x => x.ItemId == tempTargetId)
}
rpt.DataSource = s.GetQueryable<SearchResultItem>().Where(predicate);
rpt.DataBind();
}
I need to replicate the Google Analytics date picker (plus a few new options). Can anyone tell me how to highlight all the cells on a calendar between two dates. My basic JavaScript is OK but I think I'm getting a bit out of my depth.
I'm using JQuery 1.5.1 and JQuery UI 1.8.14.
In needed to replicate Google Analytics date picker as well. I know you were asking just about highlighting cells, but if someone else would prefer complete solution, you can see my answer from another question: jquery google analytics datepicker
Here's a solution using the built-in 'onSelect' event (jsFiddle):
$(document).ready(function() {
'use strict';
var range = {
'start': null,
'stop': null
};
$('#picker').datepicker({
'onSelect': function(dateText, inst) {
var d, ds, i, sel, $this = $(this);
if (range.start === null || range.stop === null) {
if (range.start === null) {
range.start = new Date(dateText);
} else {
range.stop = new Date(dateText);
}
}
if (range.start !== null && range.stop !== null) {
if ($this.find('td').hasClass('selected')) {
//clear selected range
$this.children().removeClass('selected');
range.start = new Date(dateText);
range.stop = null;
//call internal method '_updateDatepicker'.
inst.inline = true;
} else {
//prevent internal method '_updateDatepicker' from being called.
inst.inline = false;
if (range.start > range.stop) {
d = range.stop;
range.stop = range.start;
range.start = d;
}
sel = (range.start.toString() === range.stop.toString()) ? 0 : (new Date(range.stop - range.start)).getDate();
for (i = 0; i <= sel; i += 1) {
ds = (range.start.getMonth() + 1).toString() + '/' + (range.start.getDate() + i).toString() + '/' + (range.start.getFullYear()).toString();
d = new Date(ds);
$this.find('td a').filter(function(index) {
return $(this).text() === d.getDate().toString();
}).parents('td').addClass('selected');
}
}
}
}
});
});
I became desperate and came up with a solution on my own. It wasn't pretty but I'll detail it.
I was able to construct a div that had the text boxes, buttons and the datepicker that looked like the Google Analytics control but I couldn't make the datepicker work properly. Eventually, I came up with the idea of creating a toggle variable that kept track of which date you were selecting (start date or end date). Using that variable in a custom onSelect event handler worked well but I still couldn't figure out how to get the cells between dates to highlight.
It took a while, but I slowly came to the realization that I couldn't do it with the datepicker as it existed out of the box. Once I figured that out, I was able to come up with a solution.
My solution was to add a new event call afterSelect. This is code that would run after all the internal adjustments and formatting were complete. I then wrote a function that, given a cell in the datepicker calendar, would return the date that it represented. I identified the calendar date cells by using jQuery to find all the elements that had the "ui-state-default" class. Once I had the date function and a list of all the calendar cells, I just needed to iterate over all of them and, if the date was in the correct range, add a new class to the parent.
It was extremely tedious but I was able to make it work.
