Hello,

 

You can try these 3 things to resolve the issue:

1. Ensure that there is OnCommand event defined as demonstrated here:

https://docs.telerik.com/devtools/aspnet-ajax/controls/grid/data-binding/understanding-data-binding/client-side-binding/client-side-binding-specifics

2. Wrap the script tag inside a RadScriptBlock:
https://docs.telerik.com/devtools/aspnet-ajax/controls/ajaxmanager/radcodeblock-and-radscriptblock

3. Ensure that the RadScriptBlock and the script inside are placed inside the body and after the RadScriptManager.

I hope this will prove helpful.

Hi Eyup,

 

                  thanks for reply i use external javascript file so how we put Wrap the script tag inside a RadScriptBlock.

Hi,

 

Find the <script ...></script> element which contains the link to the external js file and try to include it inside the RadScriptBlock.

Hi,

 

Yes, this is correct. Just make sure also that every script related to Telerik components is added after the script manager:

        <telerik:RadScriptManager ID="RadScriptManager1" runat="server">
            <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>

        <telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">
            <script type="text/javascript">
            //Put your JavaScript code here.
            </script>
        </telerik:RadScriptBlock>

Also, ensure that there is no script error after you disable AJAX:
