Hi,

One suggestion is that you can ajaxify the grid as shown below.
aspx:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
            <AjaxSettings>
                <telerik:AjaxSetting AjaxControlID="RadGrid1">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="RadGrid1"></telerik:AjaxUpdatedControl>
                    </UpdatedControls>
                </telerik:AjaxSetting>
            </AjaxSettings>
</telerik:RadAjaxManager>

Thanks,

Hello,

Please try with below code snippet.

For Server side binding

function openWin(id) {
               var myWindow = window.open('', '', 'width=300,height=300');
               myWindow.document.write("<p>This is 'myWindow' and id is : " + id + "</p>");
               myWindow.focus();
           }

<telerik:GridButtonColumn ButtonType="LinkButton" Text="OPen Window" UniqueName="linkbuttonopenwindow">
                   </telerik:GridButtonColumn>

   protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {

        if (e.Item is GridDataItem)
        {
            GridDataItem item = e.Item as GridDataItem;
            LinkButton lnk1 = item["linkbuttonopenwindow"].Controls[0] as LinkButton;
            lnk1.Attributes.Add("onclick", "openWin('"+item.GetDataKeyValue("ID").ToString()+"'); return false;");
        }
}

For Client side Binding

function RowDataBound(sender, args) {

               var lnkButton = args.get_item().get_cell("linkbuttonopenwindow").getElementsByTagName("a")[0]; // get link button
               lnkButton.onclick = function () { openWin(args.get_dataItem().ID); return false; } // add onclick event
           }

function openWin(id) {
               var myWindow = window.open('', '', 'width=300,height=300');
               myWindow.document.write("<p>This is 'myWindow' and id is : " + id + "</p>");
               myWindow.focus();
           }

<telerik:GridButtonColumn ButtonType="LinkButton" Text="OPen Window" UniqueName="linkbuttonopenwindow">
                   </telerik:GridButtonColumn>

<ClientSettings>
                <ClientEvents OnRowDataBound="RowDataBound" />
            </ClientSettings>

Hello Nagendra,

The Jayesh suggestion is what you need. You could pass the row index as well as the id. Check out the following code snippet:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {

        if (e.Item is GridDataItem)
        {
            GridDataItem item = e.Item as GridDataItem;
            LinkButton lnk1 = item["linkbuttonopenwindow"].Controls[0] as LinkButton;
            lnk1.Attributes.Add("onclick", "openWin('"+item.GetDataKeyValue("ID").ToString() + "," + item.ItemIndex "'); return false;");
        }
}

Kind regards,
