I tried to follow your guide, but I'm not able to figure out what step I skipped...
The problem is that when I group my items, they all get into a single group with the FQDN of the object in BindingList. For the same reason (I think), the ordering doesn't work.
I set up a RadListView whith those parameters (ViewType cannot be changed):

Hate to ask this but when I use Infragistics controls (evil competitor), they have the concept of showing an Overflow Indicator in the edit control when the text in the control will be cut off (too much text to show all of it). This is very useful for end users as they can hover over the indicator and get a tooltip of all of the text.
How can I, using the TextBox control:
Show an Overflow Indicator such that the user can see all their text in a tooltip?
OR
Have the text clip at word/characters with a "..." at the end of the control such that the user can then see all their text in a tooltip?
OR
Determine if the text has been clipped? If it is clipped then I can set the tooltip myself to the text.
By the way, I like the Telerik controls in that they "feel" better thus I'm in your forums ;)

There seems to be a problem with RTF in RadRichTextBox when interpreting \b0 and \i0 as in they are ignored.
So RTF where the text contains for example: "Test of \b Bold\b0 text" should be shown with only "Bold" in bold, but the \b0 is ignored and the rest of the paragraph is in bold. The same happens with italics and \i0.
The same RTF is shown correctly in .NET's normal RichTextBox and in Word.
This is with RadRichTextBox from 2011 Q3 (RadControls_WinForms_2011_3_11_1219_dev.msi).
Has this bug been fixed in a newer release?

Hi,
I have a menu that has excess padding on the right of all my CommandBarDropDownButton menu items that for some of our users with low resolution, is causing problems with child menu items displaying. Is there a way to reduce the amount of padding to the right of each menu item either through Visual Style Builder or through code? See image below for a visual.
Thanks,
David A.

Hi!
The RadLabel text property can contain HTML. Before -in the first release of the Telerik controls I had installed- the property in the VS2010 toolbox had a little button that called a dialog which contained an HTML editor. However, since the last 2 updates that little button has disappeared and I can't call this dialog anymore...How can I get the dialog back?
Tia,
Martin

I have enabled Sorting and Column Sorting under the Telerik ListView properties.
This ListView is updated on a regular interval. In the update method I call Items.Clear() and Columns.Clear().
I add some columns programmitically as well. However, when the code runs below it throws an "Out of range index" exception.
This only occurs after I have clicked a column header to sort it. If the column was not sorted, the code runs fine.
When I look at the Count of radListView.Items the Count is 0. This means the radListView.Item.Add method did nothing..

Hello,
In my RadGridViews>Datatime columns, the datetime are display like this for example 28/03/2012 00:00:00 .
I would like them not to display time.
I've tried to set the formatstring as "dd/MM/yyyy" in the columns properties but then in the column cells it was displayed dd/MM/yyyy, I mean litterally dd/MM/yyyy, not the the date.
So, what am I doing wrong ?
Thank you for support.
