How to use a method that is in one of my pages from the masterpage ?

I have a method called Clean ( ) on my page Register, but I want to run it from the masterpage , you can instantiate a class page ?

You could try to cast the current page to the type Register, if that cast succeeds you're there:

var register = this.Page as Register;
if(register != null)
{
    register.Clean();
}

However, normally it is nnot od best practice because a master is typically used for multiple pages. So why do you want to hardwire this master to a specific page?

  • @AlejandroMoralesLópez: so what is the type of the current page in the `SelectedIndexChangedEvent` of the `DropDownList`? Have you used the debugger? Just inspect the `Page` property of the `MasterPage`. – Tim Schmelter Apr 15 '15 at 21:44

  • You should provide descriptions of how to do these things, rather than just links. – mason Apr 15 '15 at 20:57
  • Everything is there! – Valentin Petkov Apr 15 '15 at 21:01
  • No, everything is *not there*. You need to have the content in your answer itself. A link is not sufficient. The URL's for those pages could change. Their site could go down, temporarily or permanently. – mason Apr 15 '15 at 21:02
