hi i open radwindow with the following code , my problem is if i set VisibleOnPageLoad=true the code is working but each time the page post back the Radwindow open again if i set VisibleOnPageLoad=false couldn't open radwindow

How can I show the group footer when the group is collapsed?  So that the collapsed group would show the header with the name and expand/collapse button, and directly below it the footer with all the aggregates for the group.
Thanks

I would like to be able to export data from multiple radgrids at the same time to a word document, Is this possible?

I have defined four slidingpanes in the slidingzone in the aspx file.
In the InitComplete event method I have added two new panes and removed one exisiting pane.
When I load the page, I get the error message.
When I only add panes all working fine without the error
Only when I have removed an existing pane the error occurs after page is loaded.

I'm using the the telerik version 2011.2.712.35

Any idea why the error occurs?

Best regards,

Hello,

when I resize the raddock to fit it's contents (usually the radDock's width is increaed; the radDock contains a radGrid), the title bar doesn't resize properly.
The width changes correctly, but the "drag zone" doesn't get wider.
For example if the radDock's width is increased from 100px to 200px, the left half of the title can be used to drag the radDock (the curser changes to the move icon when hovering) but when I hover the right part of the title it doesn't work.

After dragging the radDock a bit using the left half of the title, the right part also works correctly.

What can I do about this issue?
The resizing is done client side using the set_width property of the rad dock. The function is called by using:

Sys.Application.add_load(initializeRadDockResources);

I also tried using the OnClientInitialize event, but when using that the whole title has no "drag zone" after resizing. Also the title text is missing. But when the RadDock is opened a second time everything works.

Thanks!

Edit: I just checked something and the problem in OnClientInitialize is the same as in the load event handler. I just set the width to 0 before. It seems that when the radDock is opened and I set the width as described above, the value is not used until the radDock is opened the next time.

Is there a way to alter the properties of the built in tool tip for each appointment.  More specifically, i need to adjust the AutoCloseDelay property so the tool tip stays on the user's screen longer.  Right now the tool tip contains too much information to take in when it fades away after a few seconds.

Thanks,

Hi,

In the following demo page, there are CSS animations which include cursor change and arrow indicator in group pane when I drag-n-drop a column into group pane:

How do I style these animations?

TIA

I have a RadGrid in UpdatePanel1 and a Listbox and a Button in Updatepanel2.

The button in UpdatePanel2 adds items to the listbox.
 
What I'm not understanding is why when I click the button in Updatepanel2 it runs the click event and then triggers the RadGrid.NeedDataSource sub routine.Shouldn't the the click event in Updatepanel2 only post back and refresh the controls in that updatepanel?

Hello,
I have a template column which contains a lookup label. Label takes text from dictionary by ID contained in column. Column also has a templated filter which contains a combobox. When I select new item from dropdown, filter command fires and column must be filtered by combobox's ItemValue which is GUID. I  must say there is an extension method in my solution called ToGuid() which I use to convert string values. And now, when filtering command passes to server, I get the following error:

I'm not sure whether this is an error in your code or mine or whatever else. Can you please check this out?
Thank you.

I've added an ASP.NET required validator on a Telerik textbox.  I've noticed that the validator reports the contents of the textbox to be empty when the screen is first rendered, even though the textbox was prepopulated with text from a database.  Refreshing the screen seems to make the validator recognize the text again.

I know telerik textboxes render as three input controls.  Could the validator be trying to read the wrong input control?
