Dear Madam/Sir,

One column of my GridView is a GridViewComboBoxColumn.

I've added an event for RowValidated and want to check the value for this ComboBoxColumn
but I always get "Object reference not set...".
If I use a TextBoxColumn, I get the value without any problems.


Thanks in advance!

Edit: I've set .FieldName wrong... stupid error! Sorry!

In prior Versions, adding a DocumentWindow to the DockManager used to activate it, in 2009 Q3 I have to explicitely set the Active Window. Is that correct?

RadDock.AddDocument(document);
// new with 2009 Q3 to activate a newly added window
RadEock.ActiveWindow=document;

I have just upgraded to 2009 Q3 version.

I have a RADform, with a RADGridView, with anchor settings: left, right, top, bottom  (there are other buttons and text box.)

Settings as follows:
RADform:
AutoScaleMode: dpi
WindowsState: Maximized

The RADForm is a MDI child.

I found that sometimes when it is opened (especially the first fime), the RADGridview does not anchored.

But I reopened it, most of the time it can anchor as expected.

Hi

I just installed Telerik Q3 2009 WinForms BETA (2009.2.9.1016) over Q2 2009 (2009.2.9.729) and the demo program now no longer shows ChildGridViewTemplate Rows after the 1st Row in at least the following scenario:

1. Run the demo program and do to GridView, Hierarchy, Tabbed child views.
2. Expand a ChildGridViewTemplate's ParentRow (all Rows are shown as expected).
3. Collapse a ChildGridViewTemplate's ParentRow (all Rows are hidden as expected).
4. Expand a ChildGridViewTemplate's ParentRow (only the 1st Row is shown and its height has increased to fill the whole ChildGridViewTemplate).

This occurs on a per-ParentRow basis.  I could only get this to occur in the demo program.  It did not happen in my app.

Telerik 2009Q3 Beta (2009.2.9.1016), VS 2005 (v8.0.50727.762 SP.050727-7600), .Net2 (2.0.50727), XP SP3, Core2Duo 2.99GHZ with 3GB.

I have a bar graph and I need to change the color of the label in the series.
||||||||||||||||||||||||||||||||||||||||||||||||||||28
||||||||||||||||||||||||||14
Say it looks like this, I want to change the forecolor of the "28" and "14" to be white as the background is a dark blue.
Is this posible andif so how?

I just installed Telerik Q3 2009 WinForms BETA (2009.2.9.1016) over 2009Q2 (2009.2.9.729) and I get a error when I try to expand my 3rd-level ChildViewTemplate (MasterGridView being 1st level).  The only RadGridView change mentioned was combined Vertical Scroll Bar for Grids with ChildTemplateView's.

Hello,

My current code:

AddHandler myItem.Click, AddressOf Me.ListBoxClick

Me.RadListBox1.Items.Add(myItem)

Private Sub ListBoxClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs)

Dim myItem As RadListBoxItem = sender

Dim myIndex As Integer = ???    <---- How can I get the index?

Me.RadListBox1.SetSelected(myIndex, True)

End Sub
