Hi indradeo,

Check this example. Now please take its reference and correct your code.

HTML

    OnRowDataBound="OnRowDataBound">
    <Columns>
        <asp:BoundField DataField="Item" HeaderText="Item" />
        <asp:BoundField DataField="Date" HeaderText="Date" />
    </Columns>
</asp:GridView>
