When I go to property builder and finish, the designer.vb deletes the grid's declaration, and the only way to get it back is to delete the grid and move it back on the form. What's going on?

The control would allow you to define commands.
Like "Quit", "Save file", "Save all" and so forth.
The definition would contain everything you need for a command. It's event callback, toolstrip icon, tooltip text, short cut key and so forth.

The main goal of this would then be that you could then use these commands from anywhere. Like to add a "Save all" entry in the main menu you would just point to the command managers "Save all" entry and be done with it.
If you want the same functionality in a context menu or on a tool strip you would just point to the same command manager and the same command.
Change anything in that command and all places will be updated with the new icon, text or whatever.
The idea would be to get rid of the double definition of commands. If worst comes to worst you define the same icon, text and event callback in 3 diffrent places. (Menu, Context menu, Tool strip)

Using such a system the user would also be allowed to define his own toolstrips and menu choices, if he so wished because we would have a global pool of commands the user could use.

All this is featured in the excellent prof-uis package that I sadly had to leave behind because it's MFC & C++ only

I have a data table with a GUID column I am binding to the grid view.  After setting the data source, I am programmatically setting a group by expression, setting the column type for the GUID column to System.Guid and hiding the GUID column.  I have also enabled autosizing on all columns as well as on the master table.

Problems:

(1) As I scroll through the grid, seemingly randomly some rows display a portion of the hidden column.  There is no rhyme or reason to it - scroll to the bottom, and then back to the top and the first row shows part of the hidden column.  Scroll just enough until the column is off display and then back, and sometimes the hidden column is gone, other times not.

(2) Nothing I do, no property I set, nothing will cause the columns to autosize.  They all reset back to 50 wide.  I can resize the columns manually and they stay.  But nothing will make them columns start out properly sized, including setting column widths when defining the master table layout.

(3) When issue 1 happens on any row, the columns for that row are no longer aligned with the column headers.  When the hidden column disappears again, the columns are properly aligned with the headers.

(4) I can't find any way to add a "command" type column to the grid.  I want to be able to add a column like the normal data grid view control where the user can click the text which appears like a hyperlink and have some action occur.  Is this not a feature or am I just missing something?

I am using Q1 2007.  HELP!  What am I doing wrong?  I REALLY want to use this control because of the display properties, but these seem like pretty big issues to me.

If I copy an exe to another PC which dll's need to go with it? I'm used to asp.net apps and just copying the controls I need but in WinForms the controls are in the GAC I guess.

Dear Telerik,

I'm using Q4 2006 version for WinForms. I created some themes suitable for my project and accordingly XML files were created. When I created setup for my project, the xml files doesn't get included in it. It gives me an error while installing the project.

Why such an error is occured.

Please reply, its urgent.

Thanks and Regards,

The grid view can be very slow if you run it under the debugger in visual studio. After some digging I have found a fix for this problem. This problem is probably not just releated to the gridview but to the whole telerik framework.

The reason is that by default visual studio enabled extra checks in among other things the pinvoke. It's used when the CLR goes from managed to native code. This apparently happens in simple things like "Bitmap.Width". The penelty for these check is a slowdown of up to 100x. So we of course want to turn them off.

One way to do taht is to add a file called "<programname>.exe.mda.config" next to your exe.
In that file copy the following
<?xml version="1.0" encoding="UTF-8" ?>
<mdaConfig>
  <assistants>
    <pInvokeStackImbalance enable="false"/>
  </assistants>
</mdaConfig>

Lastly disable 'visual studio hosting" under the debug properties. Now your  app should run as quickly as using Ctrl+F5.

I get an error message

Error loading theme a dozen times when placing a rad control on the form. This is happening after I just upgraded. How do I fix this?

I get all kinds of Telerik errors popping up in my project. I'm very concerned.... what's going on?

This occurs in several areas, but for converstaion sake, I will limit to one instance.  I have a panel bar, with Labels, text boxes, etc.  and in design mode, everything is aligned, the right text size, and exactly the way I want it.  But when that panel control is added to its Docking manager at run time, it assumes all of its settings in regards to display.  So the Font increases, it is bolded, etc.  Is there a way to prevent this from happening....

Hello, 
I have the following issues/questions with docking control

1. The form that contains the docking manager is taking around 4.5 sec average to load for the first time, while it takes 0.3 sec without it, so is there a way to boost the performance, note that if I closed the form and opened it again it doesn't long time to load.
2. I did set the min width for a dock panel, however when I changed its size i could change it to much less than the min width but when I click on the undersized panel it change size to the min width!
3. Is there a way to prevent panels from docking as tabs?

Hi guys

Unlike the DataGridView, the RadGridView seems to be missing a readonly property, is it called something else? I basically want to stop people from editing the data.

Also, is there some more RadGridView documentation in the pipeline. I really need to know how to code a connection to SQL Server and handle inserts, updates and deletes.

Regards

Mitch
