How could I get the selected value of a RadSlider using Request.Form?

Request.Form.Get("MainContent_RadSlider_Ticks_ClientState")

returns:

{"value":2,"selectionStart":2,"selectionEnd":0,"isSelectionRangeEnabled":false,"orientation":0,"smallChange":1,"largeChange":1,"trackMouseWheel":true,"showDragHandle":true,"showDecreaseHandle":true,"showIncreaseHandle":true,"width":"150px","height":"40px","animationDuration":50,"minimumValue":1,"maximumValue":7,"trackPosition":2,"liveDrag":true,"dragText":"Drag","thumbsInteractionMode":1}

What is the name "MainContent_RadSlider_Ticks_ClientState" and how quickly could I get the selected value which is 2 here?

Thanks,

I've got a modal window that's being used for Delete confirmation. The window is not centering however. See the attached.

I'd need to create 4 columns at runtime and they should be grouped in one header.

For example, imagine I have 4 columns of AM, PM, EVE and Full and they should all be under one header (Monday):

------------------------
      Monday
AM PM EVE Full
------------------------
1 1 1 3
2 1 1 4
1 1 1 3

I just made up the numbers to demonstrate there should be 4 columns appearing

How could I achieve this?

Many thanks,

Hi,

I have created a user control along with ordering, paging etc. On the first time when grid loads, master check box work good but after clicking on column for ordering, master check box did not work.
When I disable the ajax it work fine.
Please suggest...

Reyaz

Hi

I already have text AND images in my ComboBoxItems, but I only show text in the text area.

Can I also show the image of my selected item in the text area?

TIA  

Hi,

I am using RadEditor control in my website but not able to load the editor when I run the site.
Previously I was using .Net 2.0 and telerik version 2011.1.413.40 but as I mentioned in the this link
http://www.telerik.com/community/forums/aspnet-ajax/vs-extensions/314574.aspx I followed the instruction
and now I am facing the problem as "ASP.NET Ajax client-side framework failed to load." --Syntax error
for ScriptResource.axd and Telerik.Web.UI.WebResource.axd

The TargetFramework setting of my project is: .Net Framework 4;

The version of the Telerik.Web.UI assembly is: Product Version: 2011.1.413.40

Please help me in solving this issue.

Thanks

How do I get the clientside selected data key?  Only thing I can find is DisplayIndex....and not sure if that's what I want (does the display index change for an item if it's collapsed and thus hidden?)

We have a RadGrid that contains columns and a NestedViewTemplate which contains a user control that only has a RadGrid.  The export functionality has been working fine since Jan 2010, but ever since updating to Q1 2011 we receive an Object Reference error each time we try to export.  The stack trace shows that "Telerik.Web.UI.GridTableView.PrepareExport()" is the function throwing the error.  All other RadGrid export functions work fine, but they do not contain a NestedViewTemplate that contains another RadGrid.

The only way that the export will work is if I set IgnorePaging to false, but then all data that is on the other pages do not get exported to the excel.  So basically anytime the IgnorePaging is not false, you get the object reference error.  Also, if I remove the user control and just leave the empty NestedViewTemplate elements, the export works all the time.  Only when the user control (which just contains a RadGrid) is within a NestedViewTemplate do I get the object reference error.

The user control within the nestedviewtemplate is always set to visible = false, however, when you export, the radgrid within the user control, which is always visible = false, has its OnNeedDataSource event fired and after this is when you get the object reference error.  Below is the call stack

Using 2010 Q3 Telerik assembly, this problem does not exists and the RadGrid within the user control that exists in the NestedViewTemplate does not have the OnNeedDataSource event fired when exporting.

When I programmatically add a grid in the Page Init event, I understand how I can create the paging and it works.

However if the grid is not created in the Page Init, but in the Ribbon Buttonclicked event the paging command on the grid is not working. How should I enable this.
