I have a cellStyle created for the Excel file to have row striping. I also want to set any cells with numeric values to RIGHT ALIGN. I can accomplish this by checking the value of the cell, and if numeric I setCellStyle(styleRightAlign) where styleRightAlign is the name of my right align cellStyle.
However, this overrides the existing style and my cell no longer has the correct background color. It's right aligned correctly, but how can I just "add" a cell style rather than override the existing?
Is this possible?
I've looked at using the CellUtil setCellStyleProperty method but I'm unsure how to create an instance of this in ColdFusion, and if it is what I need for this.
UPDATE
So it looks like CF 11+ have the CellUtil available, but CF 10 does not. Figures. So I'm creating a separate style with my row striping for alignRight that includes the background color. If anyone has any ideas how I can just align the cell without affecting the existing cellStyle on it, I'd love to hear it.

The context
In a wxWidgets (version 3.0.2) C++ application, I am trying to hide the first column of a wxListCtrl.
I did not find a member function to do this so I tried to set the width of the column to 0:
myListCtrl->SetColumnWidth(0, 0);
first argument being the column ID and second one the width in pixels (wxListCtrl documentation).
After running the program, the header of the first column is hidden as I wanted but the data of each row of the first column overlaps the data of each row of the second column (which is not hidden). It is obviously not what I want. The header and the data of the first column should be hidden.
The question
In wxWidgets 3.0.2, is there a way to hide the first column (header and data of each rows) of a wxListCtrl?
I don't believe you can. You have a few options.
Delete the column using DeleteColumn(int columnIndex). You aren't losing any data, just the display of it, so you can always re-insert the column and repopulate it if you need to re-add it. Obviously this could be time consuming if your data is excessively large.
Depending on your application, just don't create the column in the first place. You don't say why you want to hide it, so if you just don't want it, don't add it.
Implement your control as a virtual control which gives your application control over what to display where. The burden of data display management falls to you to do manually but you have a great deal more flexibility. Inherit the class with wxLC_VIRTUAL style and implement OnGetItemText http://docs.wxwidgets.org/3.0/classwx_list_ctrl.html#a92370967f97215e6068326645ee76624
Edit:
To expand on the comment question, how to get the selected item index:
The wxListCtrl is a little weird when it comes to selected items. I'm sure it has to do with needing to support report, icon, etc. different views. When dealing with a multi-column report mode, you might find that you can only select items in the first column. If you are on Windows, it should automatically be set to "Full Row Select" but I don't know about other OSs.
Anyway, here is a utility method that returns the first selected item (note that you can support multi-selection if you want to).
//Get the item currently selected
int ListView::GetItemSelected() const
{
for(int i=0; i<GetItemCount(); ++i)
if (GetItemState(i, wxLIST_STATE_SELECTED) == wxLIST_STATE_SELECTED)
return i;
return -1;
}
If you want (and it makes sense), you can connect the list item selected event.
this->Connect(wxEVT_COMMAND_LIST_ITEM_SELECTED, wxCommandEventHandler(ListView::selected_Changed), NULL, this);
and within that event handler, get the selected item and do what needs doing (depending entirely on your application).
You will note that I'm using a derived class here which just makes things a lot easier but you don't have to. You can connect to something like MyMainForm::sqlResults_selectedChanged or whatever.
There is more than one way to accomplish all this and you can also find some good suggestions and help here: https://wiki.wxwidgets.org/WxListCtrl
I’m getting crazy with Pro Motion table and I cannot find any discussion about this online.
I’m using a PM::TableScreen and I need to have selectable table rows. I manage the raw selection in an array but I don’t know how can I get the cell object to call cell.accessoryType = UITableViewCellAccessoryCheckmark if is selected or cell.accessoryType = UITableViewCellAccessoryNone if not selected.
Here is the gist of my screen: I try to intercept the cell passing a value in the arguments (row) but I cannot find a method to get the cell object.
In my original idea the place for the selection is inside my tapped_cell method byt maybe there is a better way to manage a multiselection.

You don't want to memoize the table data. I've created a pull request with the fix:

Hard to summarize here, although I know Stackoverflow doesn't like us relying on links.
I have a situation where I'm using the IEditorDataFilter interface within a custom UltraGrid editor control to automatically map values from a bound data source when they're displayed in the grid cells. In this case it's converting guid-based key values into user-friendly values, and it works well by displaying what I need in the cell, but retaining the GUID values as the 'value' behind the scenes.
My issue is what happens when I enable the built-in group by functionality and the user groups by a column using my editor. In that case the group by headers default to using the cell's value, which is the guid in my case, so I end up with headers like this:
Column A: 7F720CE8-123A-4A5D-95A7-6DC6EFFE5009 (10 items)
What I really want is the cell's display value to be used instead so it's something like this:
Column A: Item 1 (10 items)
What I've tried so far
Infragistics provides a couple mechanisms for modifying what's shown in group by rows:
GroupByRowDescriptionMask property of the grid (http://bit.ly/1g72t1b)
Manually set the row description via the InitializeGroupByRow event (http://bit.ly/1ix1CbK)
Option 1 doesn't appear to give me what I need because the cell's display value is not exposed in the set of tokens they provide. Option 2 looks promising but it's not clear to me how to get at the cell's display value. The event argument only appears to contain the cell's backing value, which in my case is the GUID.
Is there a proper approach for using the group by functionality when you're also using an IEditorDataFilter implementation to convert values?
This may be frowned upon, but I asked my question on the Infragistic forums as well, and a complete answer is available there (along with an example solution demonstrating the problem):
http://www.infragistics.com/community/forums/p/88541/439210.aspx
In short, I was applying my custom editors at the cell level, which made them unavailable when the rows were grouped together. A better approach would be to apply the editor at the column level, which would make the editor available at the time of grouping, and would provide the expected behavior.
I have a cfgrid with 5 columns. The funny thing is, it's showing a sort of extra column to the right, but without any of the formatting that applies to the rest of the grid. I can't seem to get rid of it by playing with the width of the grid or the fields... How can I get it to go away? (It shows up in Firefox and IE, but not in Chrome)
I'm attaching a screenshot of the grid to show what I mean.
It's because you have autowidth="true" set on the cfgrid.
Not having access at the code, I can only make an assumption. I believe you have your last column "centered" by using dataalign="center" within your cfgridcolumn. But did you add headeralign="center" to that cfgridcolumn? It fixed my issue.
Using the Pie Chart ( http://code.google.com/apis/visualization/documentation/gallery/piechart.html ), is there anyway I can add/remove a data after the page was loaded?
For example, after a user click on a link I want to be able to remove one of the parts of the pie and when he clicks another link I want to add a new part.
Thanks.
Joel
Yes, it is possible. I've thrown together an example on JsFiddle. It's probably not exactly how you would do in a production environment but it should give you an idea.
Basically what I do is:
Make the DataTable and PieChart accessible from outside the drawChart() function (or whatever your draw method is called)
Use the removeRow() method on the DataTable object
Redraw the chart.
Joel, I did what you asked using a ckeckbox instead of links. When the checkbox has unchecked, I called data.removeRow(data.getNumberOfRows()-1) as jensgram points out. And when it was checked I called addRow(theDeletedRow).
Just take care that the added/removed row should be the last one of the RataTable (removing the first row doesn't make all other elements in the array go up), to keep the deleted value in a variable so you can add it again later, and try to specify colors in your options, so each part of the pie doesn't change of color (it gives the appearance that it is a completelly different pie, instead of the same one without just one part).
