ASP.net Usercontrol Base and child how to initialize Base controls ????

Question

HI ,

1.create Base usercontrol which contains a label and sets text of it to be "test1" this is set in the ascx page. 2.Create a user control which inherits from the base user control. 3. Now on the page load of the child control i try to do:

protected override void Page_Load(object sender, EventArgs e) { //Exception thrown by this as Label1 is null this.Label1.Text = "sasasas";

}

However i get an exception because the Label1 is null.

Can aonyone tell me how to initialize the base controls controls when the child control is created?????

thanks Niall

Hi NBrowne,

Try calling EnsureChildControls() before you access the label. Cheers Tigger

As RPM1984 commented: do not inherit from your Webusercontrol but nest it inside of your other Usercontrol. When you have exposed a Control(f.e. your Label or its Text property) as property in the "parent"-UC, you can access it from your "child"-UC.

Besides, always use LoadControl to initialize an dynamically added Usercontrol and not the constructor (what might be the cause that the Textbox is NULL).
