Hi,

I want to use a variable used (that is entered by a user of the application) in another xaml page. How do I do that? For instance if the data entered on the previous page then a certain button must be disabled in another page.

hi, you can do this by using Query string, or session.
e.g

put some check in the session e.g

session["disablebtn"] = "yes";

and when the next page is loading put a check on the Page_Load event
e.g

 if(convert.ToString(session["disablebtn"]).Equals("yes"))
{

      //  Disable the Button.
}

Let me know if the above solution doesn't help you.

Thanks

XAML means he's using WPF, not ASP.NET

If you tag your questions properly, it would help. This is WPF ? If the two pages are not child and parent, if you don't have a direct relationship where you can call a method or set a property, then you should set up a delegate so that when the data changes, it can call a method telling this page to change the state of the button. I'm not sure what you mean by 'previous page', is this perhaps silverlight ? The same rule would apply, a delegate is the best way to communicate between forms.

Hi, it's a WPF Page and on the 1st page I have :

SQL

sqlIns = "SELECT [Group] FROM [RIMS_DB].[dbo].[Users] WHERE [UserName] = '" + cbUser.Text + "'AND [Password] = '" + pbPass1.Password + "'";

C#

while (dr.Read())
               {
                      groupUs = dr["group"].ToString();
                      if (groupUs == "Admin")
                     {
                       gbwelcome.Visibility = System.Windows.Visibility.Visible;
                      }

else (groupUs == "Admin")
{// blah blah blah}
}

On the 2nd Page I want to call that user logged in which is an admin or any user then disable certain buttons.
