How to find controls in a repeater header or footer

Question

I was wondering how one would find the controls in the HeaderTemplate or FooterTemplate of an Asp.Net Repeater control.

I can access them on the ItemDataBound event,

Answer 1

Find control into Repeater (Header, Item, Footer)

public static class FindControlInRepeater
{
    public static Control FindControl(this Repeater repeater, string controlName)
    {
        for (int i = 0; i < repeater.Controls.Count; i++)
            if (repeater.Controls[i].Controls[0].FindControl(controlName) != null)
                return repeater.Controls[i].Controls[0].FindControl(controlName);
        return null;
    }
}
