Default Button enable property - Late binding

Dear Friends

I have number of buttons like add, edit, save, etc. in different forms (in more than 50 forms) If one button is clicked other buttons' enabled property will be true or false in a particular form.

I want one method which will be written in a module or in a class. This will be used to control all buttons in various forms. Please give sample coding for this.

'This is in one form1

Private Sub cmdAdd_Click(ByVal sender As Object, ByVal e As
System.EventArgs) Handles cmdAdd.Click

      btnAddStatus()

   End Sub

Public Sub btnAddStatus()

      cmdAdd.Enabled = False
      cmdEdit.Enabled = False
      cmdSave.Enabled = True
      cmdDelete.Enabled = False
      cmdView.Enabled = False

   End Sub

I want like this as below
************************************************** *********
Private Sub cmdAdd_Click(ByVal sender As Object, ByVal e As
System.EventArgs) Handles cmdAdd.Click

      btnAddStatus(me)

   End Sub
**************************************************

Module Test

public sub btnAddStatus(byval obj as Object)

           obj.cmdAdd.Enabled = False
           obj.cmdEdit.Enabled = False
           obj.cmdSave.Enabled = True
           obj.cmdDelete.Enabled = False
           obj.cmdView.Enabled = False

end sub

End Module

is it possible to make a common method to activate buttons. Please
rectify the error and send.

Hey,

Why not use findcontrol instead, instead of passing an object (which you can't pass the object) like that. You could make that method a custom page class method which all your pages inherit from.

public class CustomPageClass
  public sub ChangeStatus(objStatus as CurrentStatus)
     Dim cmdAdd As Button = Me.FindControl("cmdAdd")
     if (cmdAdd IsNot Nothing) Then cmdAdd.Enabled = ..

     etc.
  end sub
end class

Hi...
Since you are using .NET 2.X, you can use "My" Object

The My.Application.OpenForms gives a Collection of currently open Forms

Then, you can iterate through the forms collection and then set

foreach frmSet in My.Application.OpenForms
    frmSet.cmdAdd.Enabled=false
        ..............
And so on :)
