Hi,

I implemented seperate projects, for each first time loading a page of each project it takes almost 10 seconds even the page is blank. Once the project is loaded, it is fast to load other pages in the same project. May I have your suggestion to improve the performance?

Regards,

Duy

Using RadMenu Client Side only

Hi,

We have an old menu in JS files that cause problems.
We want to use RadMenu as a replacement but we want to replace only the client side code.
We want to use only the client side code of the RadMenu without the server control.
Is it possible at all?

Thanks

PanelBar Behavior

I currently use the TabStrip with Mulipage controls to display and edit some 300 or so TextBoxes and other controls. I really like the advantage the PanelBar has to offer as far as the ability to display all sections at the same time and I would like to replace the TabStrip with the PanelBar. However, using the “FindItemByValue” is not very practical at all in this case. Can you recommend how to achieve the effect of the PanelBar without hiding the controls behind a parent control, maybe a combination of other controls? Is there a way to expose the controls inside the PanelBar and not having to do a “find” to get to them?

Thanks for the help,

Filter Templates and Rad ListBox

I put several rad list boxes in filter templates on a grid.
When the grid becomes too wide for the page and adds scroll bars, the rad listboxes become fixed on the page and the grid scrolls horizontally under them...

RadAjaxPanel

I'm not sure whether I have posted this in the correct forum. I have placed a RadAjaxManager at the top of my page, put a RadAjaxPanel on the page and then dropped a treeview into it. I also have a button and a textbox. The treenodes are generated dynamically by the code. I select a node at runtime and then hit the button which is supposed to write the node's value to the textbox, but this does not occur. If I used a design time generated node, it works but I have to generate the tree from a query. Here's the button click code:

TextBox1.Text = TreeView1.SelectedNode.Value.ToString();

I am under the impression that selected node's value should persist using the ajax panel. Can you help me?

Thanks,

Dave

<

telerik:radtreeview id="RadTreeView2" runat="server" width="100%" height="100%"

datasourceid="ObjectDataSource1" datafieldid="ID" datafieldparentid="ParentID"

datatextfield="Text" OnNodeClick="RadTreeView2_OnNodeClick">

<telerik:RadTreeNodeBinding Expanded="true" />

</DataBindings>

</

telerik:radtreeview>

<

asp:ObjectDataSource ID="ObjectDataSource1" runat="server"

TypeName="xxxx.Component.Classes.SiteDataItemCache" SelectMethod="GetSiteDataItems">

</

asp:ObjectDataSource>
2. in the codebehind

protected

void RadTreeView2_OnNodeClick(object sender, RadTreeNodeEventArgs e)

{

SiteDataItem item = (SiteDataItem) e.Node.DataItem;

}

3. THE PROBLEM
the e.node.DataItem is always null.
Can anyone tell me why and how i can make this the SiteDateItem that is bound to the tree node?

Delete and Update

Hello there,

I am trying to use RadGrids own Insert/Update/Delete method in order to edit or delete any records i want.

I have 2 columns on my table Group_id and Group_Name where group_id is Auto Increment.

I copy and pasted the code from http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/alleditablecolumns/defaultcs.aspx for VB.NET and modified but it does nothing.

When I edit and press update button it says: Group with ID 15 is updated! but nothing changes! also when I press Delete button nothing happens...

This is my code

                    Imports System.Data.SqlClient         
            Imports Telerik.Web.UI
