HI All:

I have used a variation the Javascript code here to warn the user about moving to a new page if there is unsaved data on the current page.  The "set_cancel(true)" statement stops the grid from moving to another page.  However, the page number in the pager control advances to the new page (i.e., If I click the "next page" button but cancel the page, the grid stays on page one but the pager shows page 2).  Is there any way to block this behaviour (or failing that is there any way I can set the page number back to the original)?

Thanks for your help.

Hi, I am deciding whether to use the TreeViewCombobox method, as shown in the demos that come with telerik installation.

/TreeView/Examples/Functionality/TreeViewComboBox/DefaultCS.aspx

I need to ensure that the selection of treeeview item is possible through the keyboard. so far i have try navigating the treeview in the demo page but have not been successfull.

To expand the dropdown and make the treeview visible i use ALT + Down arrow key. This works. But then i cannot set focus to the treeview no matter what i do. Can anyone please tell me whether it is possible or any key combinations.

Thanks.

Hi,

mac os x lion doesn't display horizontal scrollbar and that causes the columns to appear unaligned with the headers! I put here the example of the radscheduler but that happens pretty much everywhere. Has anyone noticed this already?

Hi

I'm trying to implement client side hierarchial RadGrids as described here: 
http://blogs.telerik.com/vladimirenchev/posts/08-09-09/how-to-telerik-radgrid-master-detail-client-side-data-binding-using-linq-to-sql-and-webservice.aspx 

This works great for 2 levels of hierarchy (RadGrid1 has a NestedView in which RadGrid2 is placed).
But as soon as I try to implement third level of hierarchy and add a RadGrid3 inside of NestedView of RadGrid2 I get dramatically worse performance - about 2 minutes to get page rendered (against 7 seconds for page with 2 levels). Page contains just pure markup, without any data bound. 

Please advise, what can be done in order to workaround this performance issue.

These are the test samples I've made:
First one is a quite fast 2 levels case (contains just a label inside of RadGrid2 NestedView), second is a slow one with RadGrid3 instead of label:

Label:


RadGrid:

Another developer also has the same requirement and his question is at: http://www.telerik.com/community/forums/aspnet-ajax/ajax/block-access-to-controls-in-the-page-on-ajax-postback.aspx. I wasn't sure whether adding a reply to his indicating my need to know the answer as well (since there's no way to "follow" or "subscribe" to a question unless you reply to it) or adding a new thread was appropriate. I chose to add a new thread.

Our Telerik version is 2012.1.215.40. I tried the following code, which I saw in a demo:

    <telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
        <script type="text/javascript">
            var currentLoadingPanel = null;
            var currentUpdatedControl = null;
            var idOfControl;

            function RequestStart(sender, args) {
                currentLoadingPanel = $find("<%= AjaxLoadingPanel.ClientID %>");
                // The control clicked is inside a RadAjaxPanel.
                // <telerik:RadAjaxPanel ID="AssessmentFilterAjaxPanel" runat="server" height="66px"
                // width="186px" HorizontalAlign="NotSet" LoadingPanelID="AjaxLoadingPanel" style="margin-right: 0px">
                 // <asp:PlaceHolder ID="AssessmentLinksPlaceholder" runat="server" EnableViewState="true"></asp:PlaceHolder>
                 // </telerik:RadAjaxPanel>
                 // The hyperlinks are created dynamically (it's faceted search) and the IDs start with "Assessment"
                idOfControl = args.get_eventTarget();

                if (idOfControl.indexOf("Assessment") > -1) {
                    // This control is inside a  RadAjaxPanel
                    // <telerik:RadAjaxPanel ID="PortfolioAjaxPanel" runat="server" Width="720px" HorizontalAlign="NotSet"           
                    // LoadingPanelID="AjaxLoadingPanel">
                    currentUpdatedControl = "<%= AssessmentInstanceRepeater.ClientID %>"; //
                }

                //show the loading panel over the updated control
                currentLoadingPanel.show(currentUpdatedControl);
            }

            function ResponseEnd() {
                //hide the loading panel and clean up the global variables
                if (currentLoadingPanel != null) {
                    currentLoadingPanel.hide(currentUpdatedControl);
                    currentUpdatedControl = null;
                    currentLoadingPanel = null;
                }
            }
        </script>
    </telerik:RadCodeBlock>   

The code inside the RadCodeBlock is not executed. I also refer to jQuery version 1.7.1 and use it successfully with $.noConflict();. This is the order of the scripts included (just in case this is the problem):

In the BODY:
    <telerik:RadScriptManager ID="ScriptManager1" runat="server" EnableTheming="True">
        <Scripts>
            <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />
            <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" />
            <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQueryInclude.js" />
        </Scripts>
    </telerik:RadScriptManager>
    <script src="scripts/jquery-1.7.1.min.js" type="text/javascript"></script>
    <script src="scripts/jquery-ui-1.8.18.custom.min.js" type="text/javascript"></script>  

[The RadCodeBlock goes here]

And right before closing the BODY:
    <script language="javascript" type="text/javascript">
        $.noConflict();

      jQuery(document).ready(function($) {
           // My code handling modal pop-ups, inline editing, hiding and showing content. This works correctly.
        });
    </script>

The RadAjaxManager has the following AjaxSetting:

            <telerik:AjaxSetting AjaxControlID="AssessmentLinksPlaceholder">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="ClearAllLink" />
                    <telerik:AjaxUpdatedControl ControlID="AssessmentAppliedFilterPlaceholder" />
                    <telerik:AjaxUpdatedControl ControlID="AssessmentLinksPlaceholder" />
                    <telerik:AjaxUpdatedControl ControlID="StatusLinksPlaceholder" LoadingPanelID="AjaxLoadingPanel" />
                    <telerik:AjaxUpdatedControl ControlID="AssessmentInstanceRepeater" LoadingPanelID="AjaxLoadingPanel" />
                </UpdatedControls>
            </telerik:AjaxSetting>

AJAX execution works correctly. The only problem I have to solve is how to disable or to block or to show the loading panel the other panels.

A reply to our problem is appreciated.

I have created the simplest form I can to test setting a RadTextBox using javascript.

aspx:
VB:

I get the following error:
Microsoft JScript runtime error: Unable to get value of the property 'set_value': object is null or undefined

Yes I have to do it on page load.
Yes I have to do this using javascript.

Hi,

Hi, I'm looking an either client-side or server-side to either append '*' to the Folder Name or switch the icon.  Right now, we're only allowing members to download the files and we keep that the download status.

Thanks

Can you send me the sample code to describe how to use raddatapager control with radgridview....Your demo site doesnot explain the pager control with gridview.
Thanks
