[This][1] article describes how to find control recursively by type, but the it implementation contains one flaw that leads to losing the "founded" control
Below is presented the fixed version:
/// <summary> /// Find control (recursively) by type /// (http://weblogs.asp.net/eporter/archive/2007/02/24/asp-net-findcontrol-recursive-with-generics.aspx) /// </summary> /// <typeparam name="T"></typeparam> /// <param name="controls"></param> /// <returns></returns> public static T FindControl<T>(System.Web.UI.ControlCollection controls) where T : class { T found = default(T); if (controls != null && controls.Count > 0) { for (int i = 0; i < controls.Count; i++) { if (found != null) break; if (controls[i] is T) { found = controls[i] as T; break; } found = FindControl<T>(controls[i].Controls); } } return found; }
