I am trying to get the Markup Editor to show up at Design Time. However, I am only able to get it to show up when using a radLabel and not a radTextBox. See screen shots.

My project is an Outlook Addin and I am using a Telerik RadAboutBox.

I am on Windows 7 64bit. Using Telerik WinForms 2010.1.10.409 with Visual Studio 2008 version 9.0.30729.1 SP and .NET 3.5 SP1.

I tried the latest version of the Telerik WinForms dlls, but it did not solve my problem and in fact caused more problems because a lot of the functionality I am relying on was removed (mostly to do with VisualElements). I tried to fix my project to use the new dll version, but I was unsuccessful in finding alternative solutions. So, for the time being, I am stuck in the version I am using.

Thank you.

Draw item event

Hi, everyone.

I added my items to RadListControl.
Number of items is about 120.
There are not many item but, each item need long loading time.
So, it takes very long time util all items are loaded. (about 5~6sec)
It is a critical problem!
I think if only displayed items will be loaded, reduce first loading time.
But, I can not find any event about item drawing or displaying.

Please, help me.

Changed behaviour: now doesn't select the old row (Q2 2010 SP2)

Hello,

I've developed an application using winForm Q1 2010 (on VS2008, .Net3.5);
Today I've installed the version Q2 2010 SP2, but I've found some differences.

#Question1:
In version 2010 Q1 the gridview was very smart:after re-assigning the datasource, the grid remembers the "old" selected
row and automatically re-select the row.
In the new version(2010 Q2 SP2) this behaviour seems different, the grid selects the first row.

Do you have changed something about that? How can I re-activate the behaviuor?

#Question2:
Following this page (http://goo.gl/PM8T) I've "upgraded" my app (1 solution, 5 projects, about 20 grids),
but now some grids (not all of them!!) have lost the settings (e.g. the showRowHeaderColumn property)and the skin: did you have ever seen something like that?
I really can't find any differences in the grids (all of them have the same properties).

I've readed this forum, founding nothing about: do you have any advice for me?

Thanks in advance
Francesco

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?
