Hi,
I am using Telerik RAD controls(RAD Combo, RAD TextBox ,RAD Tab etc) inside update panel. It was working fine just a few days back. Now I am getting error "Microsoft JScript runtime error: Sys.ArgumentUndefinedException: Value cannot be undefined.
Parameter name: id" before page load. I am using VS2010, framework 4.0 with Win-XP. It is always occurring on a single page while others are working fine. I matched Telerik version from Web.config and in Reference added (not using GAC here). I'd also added AJAXToolkit dll and added in reference of project. I also tried with removing Update Panel but got same result.

Problem with custom column an

Hi,

I have a custom column (who's inheriting from GridBoundColumn) who display an image related to the DataField. I override the method InitializeCell :

public override void InitializeCell(TableCell cell, int columnIndex, GridItem inItem)

when the page load for the first time, the parameter inItem.DataItem is not null and contains the object representing a row from the DataSource.

On the other side, in the PostBack, inItem.DataItem is null ! So I can't retrieve my data...

Is something wrong ?

Thank you !

enter key on selected command button in command bar saves record instead of fires command

Hi,
I have a radgrid with a custom command bar (commanditemtemplate) with a few linkbuttons on it.
Also I have the radgrid ClientSettings AllowKeyboardNavigation="true" and KeyboardNavigationSettings AllowSubmitOnEnter="true"
When I move to the command bar with the TAB key and select a linkbutton (or use the associated AccessKey to select it immedeately), then use the ENTER key to fire the button, instead the selected record is opened for editing.
How can I skip the SubmitOnEnter when I have the linkbutton selected?

I tried the code below, it gets fired when the enter key is pressed, but still the record is selected instead of the command fired.
Any ideas?

Thanx in advance,

Regards,
Frank

Telerik.Web.UI.RadGrid.prototype._canHandleKeyboardAction = function (e) {

var keyCode = e.keyCode || e.charCode;

if ((keyCode == 32 || keyCode == 13)

&& this.ClientSettings.KeyboardNavigationSettings.EnableKeyboardShortcuts) {

var target = Telerik.Web.UI.Grid.GetCurrentElement(e);

if (target.tagName.toLowerCase() == "a") {

return false;

}

return true;

}

odd grid height issue in Firefox

I have a grid which is set to 100% height. The grid displays search results. When a user clicks on the "find" button, the results are loaded in the grid. In IE (9), the grid appears correctly. In Firefox (15), there is a vertical space of about 125px below the grid pager and the grid doesn't extend all the way down to the bottom of its container. If the user clicks on "search" a second time, the grid extends properly. I have attached two screen captures demonstrating what it looks like in ie (correct) and firefox (incorrect). I have added a panel with colored background as a container for the grid so you can see it appears to be the grid which is not extending and not the container. This effect occurs even if I do not include this panel. My markup is below.

<asp:Panel id="pnlSR" runat="Server" Height="100%" style="padding:5px; background-color:Red;">
