I have GridEx object on my form and...
I want to add some items in it with a for...next loop. Actually I couldn't find any method for adding a new row with a custom data.
I want to select a specific row in that GridEx object. For example: I want to select the 6th row, is there anything like mygrid.rows(6).value or something like that?!
Thanks in Advance...
Assuming you have a GridEX control called grid...
To add new data:
GridEXRow row = grid.AddItem();
row.BeginEdit();
row.Cells[0].Value = "Whatever"; // refer to columns by index or name
...
row.EndEdit();
To retrieve a specific row:
GridEXRow row = grid.GetRow(5); // returns the 6th row
To select a specific row:
grid.MoveTo(5); // moves the selection to the 6th row
To add new row to gridex called MyGridEX:
object[] data = { "value0", "value1", "value2", ... };
this.MyGridEX.AddItem(data);
To select a specific row:
this.MyGridEX.GetRow(1); // select the second row

I´ve been struggling with this:
My table shows 3 records but when expanding there are like 100 columns. I used this code:
#"Expanded Data" = Table.ExpandTableColumn(#"Source", "Document", List.Union(List.Transform(#"Source"[Document]), each Table.ColumnNames(_))),
but it's not working. How can I expand simultaneously all columns? Also, inside those columns there are even more, for example I expand the first time end then those new columns have more records inside.
What could I do? Thanks in advance!
Try this ExpandAllRecords function - it recursively expands every Record-type column:
https://gist.github.com/Mike-Honey/0a252edf66c3c486b69b
This should work for Records Columns.
let
ExpandIt = (TableToExpand as table, optional ColumnName as text) =>
let
ListAllColumns = Table.ColumnNames(TableToExpand),
ColumnsTotal = Table.ColumnCount(TableToExpand),
CurrentColumnIndex = if (ColumnName = null) then 0 else List.PositionOf(ListAllColumns, ColumnName),
CurrentColumnName = ListAllColumns{CurrentColumnIndex},
CurrentColumnContent = Table.Column(TableToExpand, CurrentColumnName),
IsExpandable = if List.IsEmpty(List.Distinct(List.Select(CurrentColumnContent, each _ is record))) then false else true,
FieldsToExpand = if IsExpandable then Record.FieldNames(List.First(List.Select(CurrentColumnContent, each _ is record))) else {},
ColumnNewNames = List.Transform(FieldsToExpand, each CurrentColumnName &"."& _),
ExpandedTable = if IsExpandable then Table.ExpandRecordColumn(TableToExpand, CurrentColumnName, FieldsToExpand, ColumnNewNames) else TableToExpand,
NextColumnIndex = CurrentColumnIndex+1,
NextColumnName = ListAllColumns{NextColumnIndex},
OutputTable = if NextColumnIndex > ColumnsTotal-1 then ExpandedTable else #fx_ExpandIt(ExpandedTable, NextColumnName)
in
OutputTable
in
ExpandIt
This basically takes Table to Transform as the main argument,and then one by one checks if the Column Record is expandable (if column has "records" in it, it will expand it, otherwise move to next column and checks it again).
Then it returns the Output table once everything is expanded.
This function is calling the function from inside for each iteration.
I am looping through an excel sheet, looking for a specific name. When found, I print the position of the cell and the value.
I would like to find the position and value of a neighbouring cell, however I can't get .cell() to work by adding 2, indicating I would like the cell 2 columns away in the same row.
row= row works, but column= column gives error, and column + 2 gives error. Maybe this is due to me listing columns as 'ABCDEFGHIJ' earlier in my code? (For full code, see below)
print 'Cell position {} has value {}'.format(cell_name, currentSheet[cell_name].value)
print 'Cell position next door TEST {}'.format(currentSheet.cell(row=row, column=column +2))
Full code:
file = openpyxl.load_workbook('test6.xlsx', read_only = True)
allSheetNames = file.sheetnames
#print("All sheet names {}" .format(file.sheetnames))
for sheet in allSheetNames:
print('Current sheet name is {}'.format(sheet))
currentSheet = file[sheet]
for row in range(1, currentSheet.max_row + 1):
#print row
for column in 'ABCDEFGHIJ':
cell_name = '{}{}'.format(column,row)
if currentSheet[cell_name].value == 'sign_name':
print 'Cell position {} has value {}'.format(cell_name, currentSheet[cell_name].value)
print 'Cell position TEST {}'.format(currentSheet.cell(row=row, column=column +2))
I get this output:
Current sheet name is Sheet1
Current sheet name is Sheet2
Cell position D5 has value sign_name
and:
TypeError: cannot concatenate 'str' and 'int' objects
I get the same error if I try "column = column" as "column = column +2".
Why does row=row work, but column=column dosen't? And how to find the cell name of the cell to the right of my resulting D5 cell?
The reason row=row works and column=column doesn't is because your column value is a string (letter from A to J) while the column argument of a cell is expecting an int (A would be 1, B would be 2, Z would be 26, etc.)
There are a few changes I would make in order to more effectively iterate through the cells and find a neighbor. Firstly, OpenPyXl offers sheet.iter_rows(), which given no arguments, will provide a generator of all rows that are used in the sheet. So you can iterate with
for row in currentSheet.iter_rows():
for cell in row:
because each row is a generator of cells in that row.
Then in this new nested for loop, you can get the current column index with cell.column (D would give 4) and the cell to the right (increment by one column) would be currentSheet.cell(row=row, column=cell.column+1)
Note the difference between the two cell's: currentSheet.cell() is a request for a specific cell while cell.column+1 is the column index of the current cell incremented by 1.

I need to access the previous record of the DTH_REFER_PEDID column to make the IF comparison (DTH_REFER_PEDID-1 <> "A").
That is, I'm reading the index X, I need to compare with the index X-1
Addition_Stats = VAR Atendido_OV = PR_HIST_MOVIM_PEDID[OVITEM_Hist]
VAR linha_anterior2 = CALCULATE(values(PR_HIST_MOVIM_PEDID[STA_ITEM_PEDCL]);filter(PR_HIST_MOVIM_PEDID;EARLIER(PR_HIST_MOVIM_PEDID[DTH_REFER_PEDID])))

The error displayed is: A circular dependency has been detected: PR_HIST_MOVIM_PEDID [Addition_Stats].
How do I compare DTH_REFER_PEDID-1 <> "A"?
An easy way to work with previous or next records is:
Make sure your data is in a table with a primary key (=ID)
Make a query with all the fields as in your table and add one colum with ID+1. (or ID-1)
Make another query with the table and the query mentioned above and make a join between ID and ID+1 (or ID-1). Place all the fields of the table and the 1st query and you end up with all the values in 1 record. This way you can work with the previous or next values.
I used multi directional scrolling with a custom flow layout in a UICollectionView to create a numeric table.
The structure of the table should be like this. A numeric table which has the sum up value in the last row:
Now the first column and the first row of the table is static i.e sticky. I want the last row also to get Sticked at the bottom of the view. Kindly help me.
This is my current view of the table:
Thank You in advance.
if section == sectionCount-1 {
for item in 0...rowCount-1 {
let indexPath = IndexPath(item: item, section: section)
if let attrs = cellAttrsDictionary[indexPath] {
var frame = attrs.frame
if item == 0 {
// Assigning the size of the first column as 200
frame.size.width = 200
frame.origin.x = xOffset
}
// Configuration for the last row in the last cell.
// Subtracting the Cell height from the entire Collection View height and assigning it as the frame for the last row of the Table i.e precisely on Y position.
frame.origin.y = (collectionView?.frame.size.height)! + yOffset - CGFloat(CELL_HEIGHT)
attrs.frame = frame
}
}
}
How can i store all the records of a column in a CDaoRecordSet? I've tried this, but will only return the first record of that column:
rs.Open(dbOpenSnapshot, "SELECT Numar_inmatriculare FROM Masini");
short nFields = rs.GetFieldCount();//returns 1
If i make a "SELECT count(*) AS Numar_inmatriculare FROM Masini" and use rs.GetFieldValue(0) it returns me 13, the correct number of records.
GetFieldCount returns the number of columns in your resultset.
To iterate through the records (=rows), you have to call MoveNext until IsEOF() returns true.
rs.Open(dbOpenSnapshot, "SELECT Numar_inmatriculare FROM Masini");
while(!rs.IsEOF())
{
// do something
rs.MoveNext();
}
