Hello Sudheer,

Let me know whether the suggested code suits your scenario:

<telerik:GridTemplateColumn>
    <HeaderTemplate>
        <asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
    </HeaderTemplate>
    <ItemTemplate>
        <asp:CheckBox ID="CheckBox1" runat="server" />
    </ItemTemplate>
</telerik:GridTemplateColumn>

protected void Button1_Click(object sender, EventArgs e)
{
    bool found = false;
    foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
        if ((item.FindControl("CheckBox1") as CheckBox).Checked)
            found = true;
    if (!found)
        RadAjaxManager1.Alert("Please select at least one checkbox!");
}
