adding controls dynamically to panel in a UpdatePanel asp.net 4.0
- by softwaremonster
Hi,
I have a UpdatePanel includes some panels. I want to add to these panel some controls according to the operations. After i click any button twice or after first page load the page gives error. Either I have to use each panel without any post back [no page refresh] how can i solve this? the html code is below.
wordOrgButton enables word panel and after any operation fills that word panel.
same for userOrgButton
<asp:UpdatePanel ID="mainPanel" runat="server" Height="220px">
<ContentTemplate>
<fieldset>
<asp:Panel ID="buttonsPanel" runat="server">
<asp:Button ID="wordOrgButton" runat="server" Text="Words"
onclick="wordOrgButton_Click" />
<asp:Button ID="userOrgButton" runat="server" Text="User"
