Hey akhter,

Please refer below sample.

HTML

EmployeeId :
<asp:TextBox ID="txtId" runat="server" />
<asp:Button Text="Insert" runat="server" OnClick="Insert" />
<asp:GridView runat="server" ID="gvDaetTime" AutoGenerateColumns="false">
    <Columns>
        <asp:BoundField DataField="Date" HeaderText="Date" />
        <asp:BoundField DataField="Time" HeaderText="Time" />
    </Columns>
</asp:GridView>
