Hi Valentin,

To add a UserControl to a PlaceHolder, you use the Add method of the placeholder. Here is an example:

UserControl ucControl1 = (UserControl)LoadControl("WebUserControl1.ascx"); 
PlaceHolder phPlaceHolder = (PlaceHolder)this.FindControl("Form1").FindControl("PlaceHolder1");
phPlaceHolder.Controls.Clear(); 
phPlaceHolder.Controls.Add(ucControl1);
