Hello,
I work with radGridView in unbound mode and every time I add a column I want to add a Tag to it, indicating the object that the column derives from. However, there is no such property as Tag for columns. Is there a possible way to achieve this, like binding a property or something like this? I tried to add the object's key in gridView.Columns[index].Name property, but this has as a result the uniqueness of the columns. Please help.
Thank you in advance

Hi Guys,
I am using the document tab strip within which I have 2 tabs.The requirement is that the user cannot swap the tabs.
I prevented that by setting AllowDragDrop=false for the document tabstrip.
However when the user drags a tab, the tabstrip hints where the drop will appear by showing visual pointers in between tabs.How do I prevent this scenario.
Any help would be appreciated.
I am using Visual studio 2008.

We have a very odd requirement. The grid rows show existing data, which is not editable. It is provided for display purposes only. The user can then add rows. One of the columns is a combobox that is bound to a list of items.
The odd requirement is that the comboBox needs to provide a subset of the data when it is dropped down for editing.
Here is a scenario. The grid contains the following customer names and types:
The odd requirement is that the comboBox needs to provide a subset of the data when it is dropped down for editing.
Here is a scenario. The grid contains the following customer names and types:
- Jones Education Customer
- Smith Business Customer
- Baggins Residentical Customer
- Support System Customer
In order to get the customer type name to show up (instead of the customer type id) we need to bind the combobox to the full set of customer types. But when the user adds a new one, they cannot have the System Customer as an option in the list.
I am filtering out the items that we don't want and rebinding it. But the new list is ignored and the full list is populated.
Any tips?
My code is below:
Private Sub CustomerGridView_CellBeginEdit(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.GridViewCellCancelEventArgs) Handles CustomerGridView.CellBeginEdit ' The list of types available for selection is different from the list that is ' bound for display, so handle this here. Dim DropDownListEditor As RadDropDownListEditor = TryCast(Me.CustomerGridView.ActiveEditor, RadDropDownListEditor) If DropDownListEditor IsNot Nothing Then If (CustomerGridView.Columns(e.ColumnIndex).Name = "Type") Then Dim editorElement As RadDropDownListEditorElement = CType(DropDownListEditor.EditorElement, RadDropDownListEditorElement) Dim filteredList = OriginalList. Where(Function(d) d.IsSystem = false) editorElement.DataSource = filteredList.ToList End If End If End Sub

I recently run into weird redraw problems with the Forms Designer on a Windows XP Tablet Edition PC. Turned out to be related to the hardware acceleration settings of the graphics card driver. I've read that WPF can have problems with some display drivers. Has anybody experienced the same, in particular together with the Telerik Controls?
Symptoms were:
Controls do not draw correctly in designer mode
Container Controls do not draw
Cannot select the Task menu
Controls are invisible while moving them around on a Form
Workaround for now is to disable some of the HW Acceleration Features, especially Direct Draw related Settings.
Regards
Erwin

Hi,
I've downloaded ExCheckedListBox from CodeProject. the control extends the ability of CheckedListBox by adding DataBinding feature.I have 3 tables: Table1,2 and Table3. Here is data for them:
Table1
ID1 Name
1 name1
2 name2
3 name3
Table3
ID3 price
1 200
2 300
3 400
Table2 (Joins Table1 and Table3)
ID1 ID3
1 1
1 2
2 3
Items of ExCheckedListBox are selected from Table 3.
When the user navigate records of Table1 in a RadGridView only the items which are related in Table2 must be checked. that is
when record with ID1=1 of Table1 is selected, then only price 200 and 300 must be checked in the ExCheckedListBox. Because in Table2, ID1=1 has two related records: 200(ID2=1) and 300(ID2=2) .
But how?
I've tested the Value property but I was not successfull.
Please guide me.

Hello,
I was wondering if there was a AllowClearCell property (or something similar). I don't want the user to right-click on a cell and select the Clear Value function on some on my cells. Is there a way other than the event CellValueChanged?
If the person wants to clear the value of a cell, I want him to click in it and edit the value to leave nothing in it. I want this mainly because I have code in the CellEndEdit and because I don't want the values in my ComboBoxColumn to be cleared (It must be one of the values in the list).

I have an editable grid where the first column is a combobox.
I am using gridView1.ClearSelection to clear any selection because the customer wants the grid to appear with no default selection.
However, the first cell of the first row is still selected.
I've tried everything I can think of, but nothing seems to be unselecting that first cell in the first row.
I attached a screen shot in case this is not clear.
Thanks!
