How to change a Radgrid column value after binding?

Hi,
I have a Radgrid and I bind it with SqlAdapter. My problem is that I want to change just one column's value. Is that possible? Thank you.

My column name is IsShadow and it binds true or false. I cannot change it. If value is false or true, I change column text appearence not database update.

How do I get rid of the ";" Column Group Separator

My grid is grouping FirstName, LastName Grade just fine. However it is puttng a ";" inbetween each column value in the group item row.
Example: Michel; Hobbs; Grade:2
I need it to be Michael Hobbs Grade:2 without the ";".

Is there any way to turn off the ";" so it doesn't show?

Thanks,
Michael Hobbs

RadTabStrip misbehaves in Chrome and Firefox

Hi,

I have a RadTabStrip that behaves nicely with an iframe in Internet Explorer but it does not behave in Chrome or Firefox. The RadTabStrip keeps overlaying the iframe in the other non-Microsoft browsers while the RadMultiPage does not. I used the style's z-index but does not have much luck. Please help.

Thanks.

ServerSide Node Expand not working

Hi,

I have the following scenario.

Creating Treeview Control in .aspx file as follows:

<telerik:RadTreeView ID="WinFabExplorerMenu" runat="server" OnNodeExpand="WinFabExplorerMenu_NodeExpand" OnClientNodeClicked="ClientNodeClicked">
</telerik:RadTreeView>

On client side, adding node to the tree and set expand mode to server side call back. After this, when I clicked the + sign on the node, the server side node expand event not firing.

function OnFederationTileClicked(sender, args) {
$('#collapseOne').collapse('hide');
var tree = $find("ctl00_MainContent_WinFabExplorerMenu");
tree.trackChanges();
tree.get_nodes().clear();
var node = new Telerik.Web.UI.RadTreeNode();
node.set_text(sender.get_navigateUrl());
node.set_category('Root');
node.set_expanded(false);
var attributes = node.get_attributes();
attributes.setAttribute("Federation", sender.get_navigateUrl());
attributes.setAttribute("Path", "Test");
node.set_expandMode(Telerik.Web.UI.TreeNodeExpandMode.ServerSideCallBack);
node.set_postBack(true);
tree.get_nodes().add(node);
tree.commitChanges();
}

ASP.NET AJAX pageLoad()-method is not called if a task will be collapsed

Hello,

I'm using the ASP.NET AJAX pageLoad()-method inside my javascript to attach e.g. a click event to a task of the gantt control. But it seems that this pageLoad()-method will not be invoked anymore if I collapse a task. And even if I expand that task again, the pageLoad()-method inside my javascript-code is not called anymore, too. The $(document).ready()-function is not working in my case because I add a special css-class as a bookmark to attach the click-event and this must happen on every page load. I hope you can help me.

Regards,
Felix

Load on demand WS with image

Hello

For several year that I'm using Load on Demand based on XML. I start notice some failures lately and I saw that the fastest way is using a Web Service. Can I build new nodes calling a Web Service and change the node image?
