ASP.NET - Setting MasterPage

Does anybody know how to set the MasterPage for an existing web form? When I try to set the property it is grayed out and cannot be changed.

Also, how do you set an event for a web form like in windows applications? Because I can't see the list of events for the form?

Thanks

Make sure you have created your web form as a "Web Content Form". Then view source / html. Locate the first line and you should see MasterPageFile. Change this to what you require.
You can also set this at runtime using Page.MasterPageFile = "SomeMasterPage.Master", but you need to do it during the PreInit stage (can't be done during the PageLoad stage).

What events do you need to set? Note that web forms work differently to windows forms. The main event you would use for a web form is Page_Load. You can also use PreRender, PreInit, etc, but Page_Load is the main one. Other controls such as buttons, text boxes, GridViews have events that are more similar to win forms.

{
    base.OnPreInit(e); 
    etc.etc
}
