I have a project and I am trying to register a custom server control (there is no .ascx
file) on the page. I am currently using
namespace MyApp.Controls{
public class CustomControl: WebControl{
public string Text
{
get
{
String s = (String)ViewState["Text"];
return ((s == null) ? String.Empty : s);
}
set
{
ViewState["Text"] = value;
}
}
protected override void RenderContents(HtmlTextWriter output)
{
output.Write(Text);
}
}
}
On my page,
<%@ Register TagPrefix="myControls" Namespace="MyApp.Controls" %>
<myControls:CustomControl runat="server" Text="What up!" />
I receive a Parser Error, with the message "Unknown server tag 'myControls:CustomControl'."
What am I doing wrong?
Well, if this control is in another class library, or even if it's in the same one, it wouldn't be a bad idea to specify control's assembly in @Register:
<%@ Register TagPrefix="myControls" Namespace="MyApp.Controls" Assembly="MyApp" %>
<myControls:CustomControl runat="server" Text="What's up!" />
Clean and rebuild your solution too in order to verify everything is compiled rightly!
