Question

I have a user control with a WebDateTimeEdit server control on it (essentially a TextBox). I’d like to be able to set some of the server control’s properties by way of the user control’s markup or programatically. for example I have this defined on my user control:

public string CssClass
{
    get { return this.WebDateTimeEdit1.CssClass; }
    set { this.WebDateTimeEdit1.CssClass = value; }
}

which allows me to do

<uc1:MyControl ID="MyControl1" runat="server" CssClass="fancycss"  />

and this works. but if I want to add a control through code,

MyControl myControl2 = new MyControl();
MyControl.CssClass = "fancycss";

this blows up because WebDateTimeEdit1 is null.

is there any way I can make this happen? also can do I do this

myControl2 .Font.Size = FontUnit.Point(8);

where the Font property is read only on the server control?

It depends on how your control is defined (is it a CompositeControl?), But generally speaking, you want to call EnsureChildControls() as the first line of the setter (and likely the getter too)
