Hi everyone,
I'm slowly going mad with Masterpages and the FindControl. After a
couple days of figuring out how to use the FindControl command from
within a Masterpage, I still can't explain why this code does not
function. As you can see if you compile it with 2005, clicking
"Button" will achieve the desired result of displaying the contents of
the textbox, however the test(); function called from Page_Load does
not do anything. (for example when I'm autoposting back)
Any help would be appreciated. Below is some test code that I wrote.
test2.aspx
---------------
<%@ Page Language="C#" MasterPageFile="~/MasterPage.master"
AutoEventWireup="true" CodeFile="test2.aspx.cs" Inherits="test2_aspx"
Title="Untitled Page" %>
<asp:Content ID="Content1" ContentPlaceHolderID="MainContent"
Runat="Server">
<asp:DropDownList ID="DropDownList1" runat="server"
AutoPostBack="true">
<asp:ListItem>1</asp:ListItem>
<asp:ListItem>2</asp:ListItem>
<asp:ListItem>3</asp:ListItem>
<asp:ListItem>4</asp:ListItem>
<asp:ListItem>5</asp:ListItem>
</asp:DropDownList>
<asp:Table ID="Table1" runat="server">
<asp:TableRow>
<asp:TableCell Width="100">Length</asp:TableCell>
</asp:TableRow>
</asp:Table>
<br />
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click"
Text="Button" />
</asp:Content>
