Hi,

I fill the grid like this:

bindingSource.DataSource = typeof(MyClass); //MyClass has a property of boolean type which are represented by checkboxes in the grid as well as string properties

grid.EnableFiltering = true;
grid.MasterGridViewTemplate.EnableFiltering = true;

grid.DataSource = bindingSource;

//refresh the binding source

As you can see, I enable filtering programatically. The problem is that no filtering for bool columns is available. I can filter text columns by manually entering some text in the filter row (however no menu/editor/designer is shown for this, I can only enter text and the LIKE operator is applied automatically), but there is no way to filter checkbox columns.

What can be the cause of such strange behavior, how can I solve this problem?

Thanks,

Maciej Aniserowicz

ExportToExcelML : Could not find neighbour element!

Hello,

I just have installed the new Q3 2009 package and I still have an error when I try to export my radgriView into an Excel file.

Before upgrading I had an index out of range error.

After upgrading I have : Could not find neighbour element!

I'am using this very simple piece of code :

                    Dim documentTop As AnalyseForm = CType(MainDock.DocumentManager.ActiveDocument.Controls(0), AnalyseForm)         
            Dim exporter As New ExportToExcelML(documentTop.DataGrid)         
            exporter.SheetMaxRows = ExcelMaxRows._65536         
            exporter.ExportVisualSettings = True         
            Dim fileName As String = "c:\ExportedData.xls"         
            exporter.RunExport(fileName)         

Thanks for your help

Combobox with duplicate display member values.

Currently using a RadComboBox which is databound from a linq query.

The ValueMember is a unique ID and DisplayMember is a user entered field.

If the user enters duplicate values for the "name" field, both will display in the combo box, however SelectedValue will always return the first matching name in the list - even if the underlying ID's are different.

Is this by design or is it a bug?

ComboBox and ListBox (obsolete as of Q2 2010)

Problem with tab key

Hi,

Normally when we press the tab key we can change the focus to the next control of the form in the order of the tabIndex property.

I have a RadForm with some controls inside but I don't know what I've done but the tab key does'nt work anymore. It just produces a sound "ding" but the focus does'nt change. It worked, but I cannot found the property wich could fix my problem.

Any Idea?

Thank you

Node label text disappears

Hi

I'm using version Q3 2007 SP1. I have a ContextMenuStrip linked to a RadTreeView. If I right-click on a node and select the "Rename" menu option, I call the BeginEdit() method of that node. If I then change the label text (but before pressing enter) and I right-click on the RadTreeView again to bring up the ContextMenuStrip, the text within the label disappears.

Any ideas?

Export to Excel

Q1 2008 SP1
Visual Studio 2008
I am unable to find "RadGridViewExcelExporter". There is no RadGridViewExcelExporter under "Telerik.WinControls.Data." I've got "Telerik.WinControls.Data." and "Telerik.WinControls.UI.", but no "Telerik.Data."

In C:\Program Files\Telerik\RadControls for WinForms Q1 2008 SP1\bin
there is a TelerikData.dll.

What am I missing?

Also, how far backward compatible with Microsoft Office/Excel is this feature?
All the way back to Office 97?

Html-like and symbols ">" or "<"

Hi everyone,

I face a problem in my project, I have a GridView with Html rendering. I use HTML-like tags in my cells. But the data between the tags is written by users. Sometimes, users wrote in the data symbols like ">" (greater than) and "<" (less than). When they do so, the data behind those symbols and the symbol itself are not displayed. Is there any workaround to display the all comment of the user in that case ?

Thanks,

[Nean]

Excel export punctuation mark

Hi,

I have a problem when I try to export data that contain punctuation mark. Words like "école, traîneau, François" give me "?cole, tra?neau,Fran?ois" in excel.

Is there a way to fix that?

I'm using the ExportToExcelML.Runexport with version 2009 Q2.

Thx
