Any Plans to Improve Performance Beyond Load-on-demand??

Load-on-demand is definitely an improvement over re-binding the entire tree on each expand/collapse. However I'm still not clear on why it is technically infeasible to just load the entire result set ONCE then have all the expand/collapse behavior occur on the client. Can you explain why that is not possible...because it would seem that would be the best way to implement a grid-like control? We love the look and feel of this control but performance has become a real issue for us when dealing with larger amounts of data.

I know that there have been multiple posts on this forum regarding this control's performance. Are there any plans in your development pipeline to remove the re-binding requirements from this control altogether and implement pure client-side expand/collapse behavior?

Thanks for your time!

WebBlue skin not working

I've been using the WebBlue skin in my application for awhile now, but after a recompile recently I get the following error:

Telerik.Web.UI.RadToolBar with ID='RadToolBar1' was unable to find embedded skin with name 'WebBlue'. Please, make sure that you spelled the skin name correctly, or if you want to use a custom skin, set EnableEmbeddedSkins=false.

I'm using the following code for the toolbar:

<telerik:RadToolBar ID="RadToolBar1" runat="server" Skin="WebBlue" CssClass="NoRoundedCornerEnds"
                            OnClientButtonClicked="DocumentToolbar_Click">
                            <Items></Items>
                        </telerik:RadToolBar>

It works fine if I switch to a different skin (such as Office2007) or use the default skin. It was working for many months prior to my recompile yesterday. Is it possible that the skin has a caching error?

Thanks,
Matt

  function GridCreated(sender, args)

     {

        var grid = sender;

        var masterTable = sender.get_masterTableView();

        masterTable.selectAllItems(true);

     }

telerik:RadGrid ID ="CandidatesGrid" runat="server" ShowStatusBar="false" AllowPaging="True" AllowSorting="True"

PageSize="3" AllowMultiRowSelection="True" GridLines="None" Skin="Outlook" EnableAjaxSkinRendering="true" Width="100%" OnItemCreated="CandidatesGrid_ItemCreated">

<MasterTableView Width="100%" ShowHeader="false" ClientDataKeyNames="ID" GroupLoadMode="Client" AutoGenerateColumns="false" CommandItemDisplay="top">

<CommandItemTemplate>

<table>

My aim is to select all Checkbox on Page Load and When click the SelectAll link in the commandItem template and to deselect all checkbox when click deselectall link in commanditem template. I also want to get the index of the individual checkbox when clicking each checkbox.
To implement this I used the javascript property. RadGrid.get_masterTableView().selectAllItems(true) as referred in the ome of the post in telerik forum.
But the result is a javascript error: object doesnot support this propert or method. I use Telerik 2008 version.
Please reply any solution to select all checkboxes on page load.
Regards,
Tinoy

Open radwindow from server side

I have to a dropdown list ddlAction inside radgrid (radgrid inside updatepanel). I need to select different items in the dropdown to open different radwindow. In my case, have to open on server side, due to one of the dropdown item does dowload file (response.writefile) so the dropdown have to do full post pack(RegisterPostBackControl(ddlAction));

The problem is when I use Window1.VisibleOnPageLoad = true; like beow, after I did Window2.VisibleOnPageLoad = true; then go back to Window1.VisibleOnPageLoad = true; both windows opened, how to avoid that? I only need to open one winow at at time, don't understand why when call window1 open after click widow2 open, both of them opened at the same time?

switch (PageIndex)

{

case 1:

RadWindow Window1;

Window1 = (RadWindow)Page.Master.FindControl("wndWindow1");

Window1.VisibleOnPageLoad = true;

break;

case 2:

RadWindow Window2;

Window2 = (RadWindow)Page.Master.FindControl("wndWindow2");

Window2.VisibleOnPageLoad = true;

break;

}
