Question

I have user control named DateTimeUC which has two textboxes on its markup:

<asp:TextBox ID='dateTextBox' runat='server'></asp:TextBox> <asp:TextBox ID='timeTextBox' runat='server'></asp:TextBox> 

I am dynamically creating this control in another user control:

Controls.Add(GenerateDateTime(parameter)); private DateTimeUC GenerateDateTime(SomeParameter parameter) {     DateTimeUC uc = new DateTimeUC();     uc.ID = parameter.Name;     return uc; } 

But when I render the page, DateTimeUC renders nothing. I checked it like this:

protected override void Render(HtmlTextWriter writer) {     base.Render(writer);      StringBuilder builder = new StringBuilder();     StringWriter swriter = new StringWriter(builder);     HtmlTextWriter hwriter = new HtmlTextWriter(swriter);     base.Render(hwriter);     string s = builder.ToString(); } 

s is empty and Controls.Count is 0. What am I doing wrong?

You must use the LoadControl( 'your_user_control_app_relative_path.ascx' ) method instead of ‘DateTimeUC uc = new DateTimeUC();’
