ASP.NET Custom user control to add dynamically
What I have done is use the Page.LoadControl method in the Page_Init to add the custom user control to a place holder on the page.
protected void Page_Init(object sender, EventArgs e){ //MyControl is the Custom User Control with a code behind file MyControl myControl = (MyControl)Page.LoadControl("~/MyControl.ascx"); //UserControlHolder is a place holder on the aspx page // where I want to load the user control to UserControlHolder.Controls.Add(myControl);}This works fine for me.
Here is the code for the dynamically loaded user control:
MyControl.ascx.cs
public partial class MyControl : System.Web.UI.UserControl{ protected void Page_Init(object sender, EventArgs e) { LiteralControl lit = new LiteralControl("Test Literal Control"); Page.Controls.Add(lit); } protected void Page_Load(object sender, EventArgs e) { whatever.Visible = true; if (IsPostBack) { whatever.Visible = false; } }}
