Property Value

Type: System.Drawing..::.Size
A Size that represents the dimensions of the client area of the control.
Remarks

The client area of a control is the bounds of the control, minus the nonclient elements such as scroll bars, borders, title bars, and menus. The SetClientSizeCore method is called to set the ClientSize property. The ClientSize property is not always changed through its set method so you should override the SetClientSizeCore method to ensure that your code is executed when the ClientSize property is set.

The Size..::.Width and Size..::.Height properties represent the width and height of the client area of the control. You can use this property to obtain the size of the client area of the control for tasks such as drawing on the surface of the control.

For more information about drawing on controls, see Rendering a Windows Forms Control.

NoteNote

You cannot bind application settings to this property. For more information on application settings, see Application Settings Overview.

Examples

The following code example resizes the specified control so the control will accommodate its formatted text. The formatted text is the Text property with the control's assigned Font applied to the text. The AutoSizeControl method in this example also has a textPadding parameter that represents the padding to apply to all edges of the control. To make the padding appear equal, align the text with the ContentAlignment..::.MiddleCenter value, if your control supports it.


Private Sub AutoSizeControl(control As Control, textPadding As Integer)
   ' Create a Graphics object for the Control.
   Dim g As Graphics = control.CreateGraphics()

   ' Get the Size needed to accommodate the formatted Text.
   Dim preferredSize As Size = g.MeasureString( _
     control.Text, control.Font).ToSize()

   ' Pad the text and resize the control.
   control.ClientSize = New Size( _
     preferredSize.Width + textPadding * 2, _
     preferredSize.Height + textPadding * 2)

   ' Clean up the Graphics object.
   g.Dispose()
End Sub


private void AutoSizeControl(Control control, int textPadding)
{
   // Create a Graphics object for the Control.
   Graphics g = control.CreateGraphics();

   // Get the Size needed to accommodate the formatted Text.
   Size preferredSize = g.MeasureString(
      control.Text, control.Font).ToSize();

   // Pad the text and resize the control.
   control.ClientSize = new Size(
      preferredSize.Width + (textPadding * 2), 
      preferredSize.Height+(textPadding * 2) );

   // Clean up the Graphics object.
   g.Dispose();
}


private:
   void AutoSizeControl( Control^ control, int textPadding )
   {

      // Create a Graphics object for the Control.
      Graphics^ g = control->CreateGraphics();

      // Get the Size needed to accommodate the formatted Text.
      System::Drawing::Size preferredSize = g->MeasureString( control->Text, control->Font ).ToSize();

      // Pad the text and resize the control.
      control->ClientSize = System::Drawing::Size( preferredSize.Width + (textPadding * 2), preferredSize.Height + (textPadding * 2) );

      // Clean up the Graphics object.
      delete g;
   }
