I am replacing a bunch of ListBox controls with ListControl
the ListBox controls start out with the height of one item, then expand to fit more items if need be
Telerik ListControl doesn't do this
please tell me the properties I need to do this, or do I manually have to adjust the height?
I tried setting AutoSize and AutoSizeItems to true but that did squatz (translation: nothing)

Hello,
I am using on every grid view in our application LoadLayout and SaveLayout.
On most grids all works fine, but on one of our grids I am getting a NullReferenceException.
The grid has a lot of columns and includes look up columns. When I try and load the layout for this particular grid, I am getting the following NullReferenceException

Hi,
I get an error when trying to create a new winforms project in Visual Studio 2010 (SP1 applied).
First I start the wizard to create the new project: Telerik->RadControls for WinForms->Create New telerik Project.
Next I select a VB RadControls Windows Forms Application and enter a Name, Location and Solution name. (same happens when creating a C# app)
After pressing OK this error message appears:
The error occured when RadControls for ASP.NET AJAX was installed on the same machine?!?!
I uninstalled and cleaned vs extensions numerous times. When only installing RadControls_WinForms_2011_1_11_419_dev.msi there's no error.
When RadControls_WinForms_2011_1_11_419_dev.msi is installed (first or after doesn't matter) combined with Telerik.Web.UI_2011_1_413_Dev.msi the error mentioned above appears.
A little help would be appreciated. It seems vs2008 doesn't have this issue ?!

I looked through the forums and haven't see anything on this, so I thought I'd post a new post to see if there's an answer or a work-around for my issue.
Summary: If I, at runtime, choose a new DataSource that shares common Column Names with my current DataSource, only the columns with shared names are shown. If there are no shared column names, then all columns are displayed. Note, that I've only tried this with DataTable objects.
How to Reproduce: Given the following four DataTables (with column names listed.)
TableA : (ID, NAME, DESC)
TableB : (ID, NAME, LOCATION)
TableC : (ITEMID, COUNT)
TableD : (NAME, COUNT)
a) RadGridView.DataSource = "TableA" -> All columns are shown.
b) RadGridView.DataSource = "TableB" -> Only ID and NAME are shown
c) RadGridView.DataSource = "TableC" -> All columns are shown.
d) RadGridView.DataSource = "TableD" -> Only COUNT is shown.
If this is a bug, would you happen to know of a workaround in the meantime?
If you need more information, please let me know.
Thanks!
Rob

I searched around the forums and couldn't find any info on how to have a nullable DateTime in a GridViewDateTimeColumn.
I want the user to be able to null out the date and save it to the DB as null. There seems to be no way to do this. The GridViewDateTimeColumn seems to not allow the user to select no date or allow them to remove the date from the cell.
We're binding to business objects that have DateTime? as a property.
Is there a way to do this in the GridView for Winforms? thanks
