[Tester]

protected void RadGrid1_SelectedIndexChanged(object sender, EventArgs e)
    {
        MakeChart(int.Parse(RadGrid1.SelectedIndexes[RadGrid1.SelectedIndexes.Count-1]));
    }

private void MakeChart(int selind)
    {
        DataTable chartdt = new DataTable();
        //Make Chart DataSource Here..
        RadChart1.DataSource = chartdt;

Hello Tester,

if you used ajax then add below code.
  <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">    
            <AjaxSettings>
                <telerik:AjaxSetting AjaxControlID="RadGrid1">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="RadChart1" />
                    </UpdatedControls>
                </telerik:AjaxSetting>
            </AjaxSettings>
        </telerik:RadAjaxManager>


let me know if any concern.
if its not working then provide your html/aspx page code.

Thanks,
