How to render UserControl with parameters in ASP.NET [duplicate]

Question

I use following code to render UserControl.

//render control to string
StringBuilder b = new StringBuilder();
HtmlTextWriter h = new HtmlTextWriter(new StringWriter(b));
this.LoadControl("~/path_to_control.ascx").RenderControl(h);
string controlAsString = b.ToString();

But I want to pass to UserControl some parameters so it should get data and update its properties just before rendering.

How it could be done? Thank you!

As answered here:

Just load the control using the path of the .ascx file, cast to proper type and set the properties one by one:

MyControl myControl = (MyControl )Page.LoadControl("~/path_to_control.ascx");
myControl.Param1= 1;
myControl.Param2= 2;
myControl.RenderControl(h)

OR:

Page.LoadControl(typeof(MyControl), new object[] {1, 2}).RenderControl(h);
