Hi
try this example :-
<asp:TemplateField ShowHeader="False"> <ItemTemplate> <asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="False" Visible='<%# GetShowEditButton() %>' CommandName="Edit" Text="Edit"></asp:LinkButton> <asp:LinkButton ID="LinkButton2" runat="server" CausesValidation="False" Visible='<%# GetShowInsertButton() %>' CommandName="New" Text="New"></asp:LinkButton> <asp:LinkButton ID="LinkButton3" runat="server" CausesValidation="False" CommandName="Delete" Text="Delete" Visible='<%# GetShowDeleteButton() %>'></asp:LinkButton> </ItemTemplate> </asp:TemplateField>
in your codebehind, you have the following:
protected bool GetShowEditButton()
{
return Roles.IsUserInRole("Admin");
}
protected bool GetShowInsertButton()
{
return Roles.IsUserInRole("Admin");
}
protected bool GetShowDeleteButton()
{
return Roles.IsUserInRole("Admin");
}
Hope this helps
