I wonder would it be possible when a listveiw is rendered as a list of checkboxes, add an option to display Select/Deselect All checkbox at the top of the list? It could separated by a horizontal line.
E.g.

Select/Deselect All
---------------------
Checkbox 1
Checkbox 2
Checkbox 3
Checkbox 4
...

Hi!

I have a grid with multiple cell selection enabled - CellSelectionMode="MultiCell".

It works great when I select multiple cells. But when I right click on one of the selected cells to bring up a context menu then all cells will be deselected except the on that I right click.

I want all selected cells to stay selected when I right click on a selected cell. Is it possible to cancel the deselecting in this case?

Thanks

I see a number of posts here and elsewhere about problems with the RadEditor control and the required field validator.

In my current project I have a RadEditor control on both the header and detail template popup of a RadGrid.  The RadGrid (and it's code behind) are relatively conventional, derived from Telerik's on-line demos.  It appears at present that the required field validator will fire on insert but not when editing an existing record.  

Has anyone else had problems like this?

Heely Guys

Story: I have a strange error when I try to save something I got this error message ( An entity object cannot be referenced by multiple instances of IEntityChangeTracker.)
I really don’t know what that is and why is it appear, it appears only when I try to save something my insert and update is working, only when I try to save something in db from my grid

After debugging I have seen that the code brake down in the Project.Name.Designer.cs ..... O.o

I'm stepping through my ASP.NET app (I didn't build it, but I'm supporting it), and all of the many references to things like RadCheckBox or RadControl seem to work perfectly well.

At the end I get an error in a very, very long script that Telerik seems to emit. There is an error in the middle of it, 'ID' variable cannot be found. It highlights 'e.detachEvents' every time, and a variable named 'ID' is nowhere close.

Any clue how I might side step this error? I hit continue and the app proceeds. And the error does not appear after deploying to the test server.

Thanks, Bob Sullentrup

Hello.  I inherited an asp.net application that uses Telerik.Web.UI.
On this one particular page it uses asp:DropDownList that works in older browsers (i.e. Firefox 14), but the DDL would not expand in current version of Firefox, Chrome, IE.  Has anyone encountered this problem yet?
Any help is greatly appreciated.

Hi,

I need to build a photograph competition page that has a RadTabStrip which I add tabs to for each competition. Each tab contains a user control, that has a RadListView to view the member's entries and two buttons, for uploading and deleting entries.

I am having difficulty with the ItemDataBound & NeedDataSource events in the RadListView. I am not sure what to do and would appreciate it if someone could steer me in the right direction.

Kind regards,
Pierre

Hi,

 

I am  facing an issue with our application, the checkbox inside the Telerik  Radgrid in our application is not unchecking when it is clicked first time (as per the business logic the  grid will be loaded as few rows checked. And this issue occurring only in this scenario).  But it is unchecking on the second time clicked.  This issue we got after migrating the  application from .Net 3.5 to 4.0.

In our 3.5 application  grid is working fine in the above said scenario. we have  tried with  4.0 Telerik and Spring DLL ‘s, still we are facing the same issue.

 

Please suggest us on what we can do  to rectify the Telerik Control issue.

Hello,

I used the following code to generate items inside a RadComboBox



My problem is it seems that any items inside the <ItemTemplate> tag does not inherit or use the css styles defined on RadComboBox's Skin attribute. The items are generated but there's no background color changes (onmouseover) on the items.

is there a way for the items to be able to use the defined skin?

Thanks
