Hello,

I am using Telerik Winform controls v.2010.1.10.504.  When in debug mode, the project works fine and builds without any issues.  When I create the exe and after I install it on the computer.  I then get the attached errors when trying to load the program.  I saw in another thread that I need to reference Telerik.WinControls.UI. When I view the references, I see that it is in there with the correct path as seen in the picture attached.  Do you have any suggestions as to what the problem may be or any other trouble shooting techniques to fix this error?

Thanks.

Hi,

I have a hierarchical grid that has HorizontalScrollState = AutoHide for the mastertemplate, and HorizontalScrollState 
= AlwaysHide for templates(0).

This correctly gives me a single scroll bar for the whole grid when the context exceeds the width of the screen, however when I scroll horizontally, the parent grid tracks with the scrollbar but expanded detail rows do not.

I am looking for the main scrollbar to scroll the entire grid contents together, ie,  master rows and any expanded detail rows.

How do I go about this?

Thanks,

Mark.

I'm looking to make a Windows form with a similar design to the Windows Control Panel Add/Remove Programs feature.

My first thought is to use a radListView, bound to my data source, but I'm wondering if there is a better choice.

Thanks

Hi,
i have a grid with a GridViewDateTimeColumn. I want to prevent the user from inserting a date which is already exists so i don't have duplicates on the gridview (or the DB). how can i achieve that?

BTW:
Can you direct me to a good example of the GridViewDateTimeColumn.DistinctValues property? it seems like i can use it but i don't know how.

Thanks

I have 12 radio buttons that I want to place in the same group on a RadRibbonBar.

I would like to have them line up almost grid like - with three rows, and four columns.

They do, however, need to remain in the same group.

Is there a way to do this, without having to deselect all items in the code behind after each and every different RadRadioButton is clicked?

There are way too many Radio Buttons to keep them all lined up vertically or horizontally.

Thank you!  :)

I've created RadForm1 and renamed it to MotherForm and put several components on it. Then I've created new RadForm(AlterForm) and inherit it from MotherForm. 
public partial class AlterForm : MotherForm

But in AlterForm designer I've got an error

The designer could not be shown for this file because none of the classes within it can be designed. The designer inspected the following classes in the file: DropForm --- The base class 'AdminControl.MotherForm' could not be loaded. Ensure the assembly has been referenced and that all projects have been built.



Where can be a problem?

Hi all,

A very annoying issue that I hope I can get some help on.   When I create Start Menu items and respond to their click events, if I have breakpoints in my code, the start menu sits on top of VS.

Not a huge issue, except that it sits over most of the menu items, so if there's a crash, I can't hit the button to force the app to stop.

Is there a way to force the start menu to close *before* it executes the event?

Thanks!

Rob.

Is it possible to resize the clock control? I'm trying to add it to a RibbonGroup, but the clock is too big to fit into it.

Thank you very much!
