Hi,

I am trying to attach onkeypress eventhandler in onclientload of radeditor. I want to check a checkbox as soon as any alphabet is entered in radeditor.

<telerik:RadEditor runat="server" ID="RadEditor1" ContentAreaMode="Div" EditModes="Design"
OnClientLoad="OnClientLoad">

<script type="text/javascript">
function OnClientLoad(editor) {
editor.AttachEventHandler("onkeypress", function (e) {
$('#<%=chktext.ClientID %>').attr('checked', true);
});
}
</script>

i get a javascript error which says UnCaught Reference Error:OnClientLoad is not defined. What should i do?

RadAjaxManager and own RenderContents

Hi,

I create some Controls (e.g. a button and a div) in CreateChildControls and add them to the RadAjaxManager in OnPreRender.
Finally, I overwrite "RenderContents" to render my own layout. But when doing this, the panel generated by the RadAjaxManager (for the LoadingPanel) isn't rendered.

Whats the best way to use the RadAjaxManager when I overwrite RenderContents? How can I "force" the RadAjaxManager to render the panel?

Thanks!

WebUserControl CustomValidator

I have a RadGrid with the EditFormSettings set to WebUserControl.

I am checking for Page.IsValid on my RadGrid_ItemCommand.

Issue with Grid in ItemTemplate

Hello,

I modeled our dropdown very similar to this example:
http://demos.telerik.com/aspnet-ajax/controls/examples/integration/gridincombobox/defaultcs.aspx?product=combobox

I am using twitter bootstrap as well as your controls within a site. I am having some issues with the radcombox in that when I turn EnableEmbeddedBaseStylesheet=true it will allow me to scroll and select items within the combobox like i want. The radcombox however is taking the look of the embedded style sheet which i do not want. if i turn it to false it now looks like i want it but when i enter an entry into the combox my information displays but I can no longer scroll through the returned items or select them. Anyone else run into this and how did you fix it?

Thanks,

<telerik:RadComboBox ID="rcmbSKU" Width="340px" runat="server" MarkFirstMatch="True" CssClass="SKUCombo" EnableEmbeddedBaseStylesheet="false" EnableEmbeddedSkins="false"

AllowCustomText="True" OnClientDropDownOpening="HandleOpen" ExpandAnimation-Type="None"

NoRecordsTemplate Cut Off

I have a RadGrid with a simple NoRecordsTemplate, just an asp:Panel containing an asp:Label. The label text is fairly long. I do not want the text to wrap, so I specified white-space:nowrap in the css class for the panel. The panel displays narrower than the text, and the text is cut off partway (and outside of the panel). If I add a specific width to the panel, it is cut off as well. I have ShowHeadersWhenNoRecord set to true, and it appears as if the no records template is being placed in a table cell the width of the first column, which would explain why it is being cut off. How do I make the no record template span multiple columns so the full width of it will be displayed?

And as a follow up: Can I put in a request that the cell the no records template is placed in be set to colspan ALL of the table columns? Since there is no data to display anyway, and thus no grid, this certainly shouldn't hurt anything, and would give us much more flexibility in the use of the no records template.
