Loading/Updating User Controls... how?

[Tarun Mistry]

Hi there, using the following code i see it is possible to load a user
control dynamically and set its properties.

Control c1 = LoadControl("MyUserControl.ascx");
((MyUserControl)c1).BackColor = "beige";
Page.Controls.Add(c1);

However, If i already have a user control on my page, as defined in the
..aspx file, it is possible to change it attributes/properties?

I have a usercontrol called "menu", one of its properties allows you to set
the title of the page. However, id like to alter this title depending on
what information has been submitted via a form, i cant figure out how to
alter its properties before it is rendered.

Please help!
Thanks everyone

In Page Load or whatever:
this.menu = (Menu) LoadControl("Menu.ascx")

In OnPreRender()
this.menu.Title = "Title"

Hi, thanks for the reply.

Ok this code compiles, but doesnt actually do anything. Any ideas?

Kind regards,

Hi,
Just include the control as a field in your page class, the page will load
the control and assign a refference to that field ...

public class MyPage : System.Web.UI.Page
{
protected MyUserControl m_control; //Must be the same as the id of your
//usercontrol.

private void Page_Load(object sender, System.EventArgs e)
{
m_control.BackColor = "beige"; //Will set the control's background color
}

}

Your control's Page_Load event handler will fire after your hosting Page
one, so you can initialize your control in your hosting page Page_Load event
handler.

Hope this helps.

Oh, Im sorry.

add:
this.Controls.Add(this.menu) right after the LoadControl() call.

And you should declare:
private Menu menu
