Re: Can't find other Controls from my own Control

I'm creating a "PopUpDatePicker" control, inheriting from Hyperlink. The goal is to click on that control, select a value from a Calendar and set this date value to a target control, usually a TextBox.

Adding something to my own question here. I've modified my OnPreRender event to look like this:

protected override void OnPreRender(EventArgs e)
{

Control control = Page.FindControl(TargetControl);


this.Attributes.Add("onclick", string.Format("window.open('DatePicker.aspx?field={0}', 'calendarPopup', 'width=230,height=209,resizable=no,statusbar=no');", control.ClientID));

base.OnPreRender(e);

}

This time I am not casting the current page from the current handler, I'm just using the Page property the Hyperlink control inherited. However, the result is just the same: FindControl() always returns null. What am I doing wrong?

Thanks in advance,

-Benton
