Adding dynamically created table to panel

May 9 2011 6:08 AM

Hi everyone.
I am making three search methods, i have three text bokses and three bottuns. search firstname, lastname, birthday. and a im retriving a list of
an object List<person> for each search. they are seperate search methods.
i am then creating Table table = new Table(); running for( int i = 0; i < list.count ; i++). and adding new row on each loop and adding a link button
to each row to view more of the person object. the id of the linkbuttons is dynamically ( i ) .
my problem is that when i have only one search option the linkbuttons works fine, but when i make the to other searches, i cant get the view more linkbutton event. can any body help me with this ??
I am using N-Tier arcitecture.i am writing my code here, assume that there is an object Person.
this is my code:
file.aspx
<body>
<form id="form1" runat="server">
<asp:Panel ID="PanelContainer" runat="server">
Firstname:
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:Button ID="Button1" runat="server" Text="search" />
 
Lastname:
<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
<asp:Button ID="Button2" runat="server" Text="search" />
 
Birthday:
<asp:TextBox ID="TextBox3" runat="server"></asp:TextBox>
<asp:Button ID="Button3" runat="server" Text="search" />
</asp:Panel>
<asp:Panel ID="PanelResult" runat="server">
</asp:Panel>
<asp:Panel ID="PanelViewmore" runat="server">
</asp:Panel>
</form>
</body>
