I am gettting the following error when using RadAjaxManager and an asp:LinkButton. 

Microsoft JScript runtime error: 'get_postBackElement().id' is null or not an object

However, if I invoke an Ajax call using the addNewClient button, and then I try and click the deleteClientLinkButton everything works fine.  It is just on the first page load that the error is thrown.

If I set ClientIdMode = AutoID for the page (http://www.telerik.com/community/forums/aspnet-ajax/ajax/radajax-broken-in-vs-2010-beta-2-in-master-content-pages.aspx) then the LinkButton works properly.  However, this renames all my controls and all my CSS is broken and no longer works.

Help please...

Dynamically Generated Radgrid with Form Template loses Dynamic Binding on Edit Click.

 

I have a RadGrid that gets Created and Bound Dynamically. But when I click edit it rebinds the grid then when I hit update it rebinds the grid and loses the datasource and so It has to call NeedDataSource again which blows away the new values before it gets to the update command.

How can I convert the date time to localtime in GridDateTimeColumn?  On ASP.net grid control, I used itemtemplate then convert the datetime field to local time using "ToLocalTime()" but I don't know how to do it in GridDateTimeColumn.                    

Thanks

Hi,

We are trying to create a mobile view of some forms which use Telerik controls for some elements, namely RadInput and RadInputMulti. All other form fields save when the form is posted back on mobile except for the Telerik based fields. When the page is posted back we are seeing a javascript error that reads 'Uncaught TypeError: Cannot read property 'PageRequestManager' of undefined', coming ScriptResource.axd at line 106. 

Is there an issue with using these fields on mobile, and if so is there anything we can do to mitigate this issue and make things work?

We are using version 2015.2.818.35 of the Telerik controls, on a SharePoint 2010 platform.

Testing is happening in Chrome and Safari for iOS, although the solution needs to work on Android as well.

Thanks for any help in advance.

Hi,

I am using RadTabstrip and Raddropdownlist.

 

Whenever the RadTabstrip is selected, the values selected in dropdownlist should be cleared, but i notice whenever i use the  categoryList.get_selectedItem().unselect(); it causes to postback. How to cancel the post back ?

 

I am using this code below

 

 <script type="text/javascript">
function OnClientTabSelected(sender, eventArgs)
{
    var tab = eventArgs.get_tab();    
    var categoryList = $find("<%=rdddlCategory.ClientID %>");   
    if (categoryList.get_selectedItem()) {      
        //categoryList.get_selectedItem().set_selected(false);
        categoryList.get_selectedItem().unselect();
       
    }
}

        function OnClientCategorySelected(sender, eventArgs) {
            alert();
            var tabstrip = $find('<%= rdTpEvents.ClientID %>');            
            if (tabstrip.get_selectedTab().get_text() != "Latest" && tabstrip.get_selectedTab().get_text() != "Working") {              
                eventArgs.set_cancel(true);
            }
        }

</script>

I have a RadToolBar in the CommandItemTemplate of a RadGrid.  I would like to (client-side) disable a button upon row click.  On row click I loop through the tool bar's items and disable the button I want.  This works but only disables the button on the top of the grid.  The command items at the bottom of the grid are left alone.  How can I disable both the top and bottom button?

 

How can I hide the title bar of a radnotification window?

I've tried this way:

 

 

But all my settings are ignored. Title is still visible. Close button either. 

I show it on postback:
