<Columns>
<asp:TemplateField HeaderText="Name">
<ItemTemplate>
<asp:TextBox ID="txtName" runat="server" Text='<%#Eval("Name") %>'></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="Emailid" HeaderText="EmailId" />
<asp:TemplateField >
<ItemTemplate>
<asp:LinkButton ID="lnkgettext" runat="server" OnClientClick="return callme(<%= txtName.ClientID %>);" Text="Gettextboxvalue" ></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
</Columns>
