How to embed user control (ascx) from code behind C#?

Embedding user controls into html page is easy but what about embedding user controls dynamically from code behind c#? Any help/suggestions would be greatly appreciated.

Solution

  • Use LoadControl to load and create a control dynamically. Then you can add it to the page's control-collection.

    UcType myControl = (UcType) LoadControl("UcType.ascx");
this.SomeContainerContainerControl.Controls.Add(myControl);

    where UcType is the type of your UserControl and SomeContainerContainerControl is the control you want to add this uc like a Panel. If you want to add it on top of the page simply use this.Controls.Add(myControl).

    You should add it in Page_Init or Page_Load (at the latest). You have to recreate it on every postback as every other dynamic control with the same ID as before (if any).
