Get ComboBox Value

I know this question has been answered many times before, but none of those replies are working for me.

I have a GridView with a TextBox column. Under specific circumstances, the TextBox column becomes a DropDown list. I have this part working fine.

I bind the DropDownList to a List<T> where T is an object, say CustomerType for example. Normally, I would bind the DisplayMember to the "TypeName" property and the ValueMember to the "CustomerTypeId" property and all would be well.

But because the TextBox column is bound to the "TypeName" of the object instead of the Id, I need some code to get the Id from the combobox.

I tried adding code to the ValueChanged event, but I am always getting the wrong element. Here is my code:

Private Sub CustomerGridView_ValueChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles CustomerGridView.ValueChanged

If CustomerGridView.CurrentRow IsNot Nothing AndAlso

Me.CustomerGridView.Columns(COL_customerType).IsCurrent Then

Dim editor = TryCast(sender, RadDropDownListEditor)

If editor IsNot Nothing Then

Dim editorElement = TryCast(editor.EditorElement, RadDropDownListEditorElement)

If editorElement IsNot Nothing Then

Dim selectedItem = TryCast(editorElement.SelectedItem.DataBoundItem, CustomerType)

If selectedItem IsNot Nothing The

Dim currentCustomer = TryCast(CustomerGridView.CurrentRow.DataBoundItem, Customer)

Customer.CustomerTypeId = selectedItem.CustomerTypeId

End If

End Sub

Any tips?

Add Tag to Column

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

Draog drop of Tabs

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.

Tabstrip (obsolete as of Q2 2010)

ComboBox Binding

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:

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 Sub
