Add the C3 of this line to your code behind file:
Protected WithEvents button1 As System.Web.UI.WebControls.Button
Just expand the #Region " Web Form Designer Generated Code " and add a
reference there to the button.

Subject: [AspNetAnyQuestionIsOk] DataList question
Hello everybody! :)
I hope somebody can give me some advice on how to solve this:
I have a very simple DataList defined like this:
<asp:datalist id="DataList1" runat="server" Width="90%"
HorizontalAlign="Center">
<HeaderTemplate>
<asp:Button ID="Button1" Runat="server" Text="New
Entry"></asp:Button>
</HeaderTemplate>
<ItemTemplate>
<Table width="100%" cellspacing="5">
<tr>
<td>Name:</td>
<td><%# DataBinder.Eval(Container.DataItem, "Name") %></td>
</tr>
<tr>
<td>Email:</td>
<td><%# DataBinder.Eval(Container.DataItem, "Email") %></td>
</tr>
<tr>
<td>Website:</td>
<td><%# DataBinder.Eval(Container.DataItem, "Website")%></td>
</tr>
</Table>
</ItemTemplate>
</asp:datalist>
Now the problem is with the "Button1" defined in the HeaderTemplate,
for some reason it does not seem to be recognized by the code behind
class:
....
protected System.Web.UI.WebControls.Button Button1;
....
private void InitializeComponent()
{
this.Button1.Click += new System.EventHandler(this.Button1_Click);
this.Load += new System.EventHandler(this.Page_Load);
}
....
private void Button1_Click(object sender, System.EventArgs e)
{
Console.WriteLine("Button1 Clicked!");
}
The first line in the InitializeComponent method gives me this
runtime error:
"Object reference not set to an instance of an object"
Now if in the aspx page I take Button1 outside the DataList is works
fine ... What am I doing wrong in the DataList then?? :(
Thank you very much for your help :)
Victor.
