Bind a method to text box in wpf
<p>I am new to <code>wpf</code>. I have a method named ABC which returns max id from the database table. I want to bind this ABC to text box in <code>Xaml</code>.</p>

<pre><code>public Int32 ABC()
{
   OleDbConnection con = new OleDbConnection();
   con.ConnectionString = ConfigurationManager.ConnectionStrings["cn"].ConnectionString;
   if (con.State == ConnectionState.Closed)
   {
      con.Open();
   }
   OleDbCommand cmd = new OleDbCommand();
   cmd.CommandText = "select (max(uhid)) from patients"; 
   cmd.Connection = con;
   Int32 k = Convert.ToInt32(cmd.ExecuteScalar());
   return k + 1; // want to assign this value
}
</code></pre>
