BUG: The ClientSize property of the TextBox control incorrectly includes the size of the borders if the BorderStyle property is set to BorderStyle.FixedSingle (814351)

MORE INFORMATION

Steps to Reproduce the Behavior

1. In Visual Studio .NET or Visual Studio 2005, create a new Windows application by using Microsoft Visual Basic 2005, Microsoft Visual Basic .NET, Microsoft Visual C# 2005, or Microsoft Visual C# .NET.
   
   By default, Form1 is created.
2. From the toolbox, drag a TextBox control onto Form1.
3. In the design plane, right-click TextBox, and then click to select Properties.
4. In the Properties window, set the Multiline property of the TextBox control to true.
5. From the toolbox, drag a Button control onto Form1.
6. Double-click Button Control to open the code view for the Button1_Click event.
7. Add the following code to the Button1_Click event:
   

   Visual Basic .NET or Visual Basic 2005 Code

      ' Set BorderStyle to FixedSingle and print ClientSize and Size		
      TextBox1.BorderStyle = BorderStyle.FixedSingle
      Console.WriteLine(vbCrLf & "BorderStyle = FixedSingle ")
      Console.WriteLine("ClientSize is " & TextBox1.ClientSize.ToString())
      Console.WriteLine("Size is " & TextBox1.Size.ToString())
   
      ' Set BorderStyle to None and print ClientSize and Size
      TextBox1.BorderStyle = BorderStyle.None
      Console.WriteLine(vbCrLf & "BorderStyle = None")
      Console.WriteLine("ClientSize is " & TextBox1.ClientSize.ToString())
      Console.WriteLine("Size is " & TextBox1.Size.ToString())
   
      ' Set BorderStyle to Fixed3D and print ClientSize and Size
      TextBox1.BorderStyle = BorderStyle.Fixed3D
      Console.WriteLine(vbCrLf & "BorderStyle = Fixed3D ")
      Console.WriteLine("ClientSize is " & TextBox1.ClientSize.ToString())
      Console.WriteLine("Size is " & TextBox1.Size.ToString())

   Visual C# .NET or Visual C# 2005 Code

      // Set BorderStyle to FixedSingle and print ClientSize and Size		
      textBox1.BorderStyle = BorderStyle.FixedSingle;
      Console.WriteLine( "\nBorderStyle = FixedSingle ");
      Console.WriteLine("ClientSize is " + textBox1.ClientSize.ToString());
      Console.WriteLine("Size is " + textBox1.Size.ToString());
   
      // Set BorderStyle to None and print ClientSize and Size
      textBox1.BorderStyle = BorderStyle.None;
      Console.WriteLine( "\nBorderStyle = None");
      Console.WriteLine("ClientSize is " + textBox1.ClientSize.ToString());
      Console.WriteLine("Size is " + textBox1.Size.ToString());
   
      // Set BorderStyle to Fixed3D and print ClientSize and Size
      textBox1.BorderStyle = BorderStyle.Fixed3D;
      Console.WriteLine( "\nBorderStyle = Fixed3D ");
      Console.WriteLine("ClientSize is " + textBox1.ClientSize.ToString());
      Console.WriteLine("Size is " + textBox1.Size.ToString());

8. On the Debug menu, click Start.
9. On the View menu, point to Other Windows, and then click Output.
10. Click Button Control.
    
    The ClientSize for various BorderStyle settings is displayed in the Output window.
