Event Type

Examples

The following code example demonstrates using the MinSize, MaxSize, ShowEffects and FontMustExist members and handling the Apply event. To run this example paste the following code in a form containing a FontDialog named FontDialog1 and a Button named Button1.

   private void Button1_Click(System.Object sender, System.EventArgs e)
   {
       // Set FontMustExist to true, which causes message box error
       // if the user enters a font that does not exist. 
       FontDialog1.FontMustExist = true;
       
       // Associate the method handling the Apply event with the event.
       FontDialog1.Apply += new System.EventHandler(FontDialog1_Apply);

       // Set a minimum and maximum size to be
       // shown in the FontDialog.
       FontDialog1.MaxSize = 32;
       FontDialog1.MinSize = 18;

       // Show the Apply button in the dialog.
       FontDialog1.ShowApply = true;

       // Do not show effects such as Underline
       // and Bold.
       FontDialog1.ShowEffects = false;
       
       // Save the existing font.
       System.Drawing.Font oldFont = this.Font;

       //Show the dialog, and get the result
       DialogResult result = FontDialog1.ShowDialog();

       // If the OK button in the Font dialog box is clicked, 
       // set all the controls' fonts to the chosen font by calling
       // the FontDialog1_Apply method.
       if (result == DialogResult.OK)
       {
           FontDialog1_Apply(this.Button1, new System.EventArgs());
       }
           // If Cancel is clicked, set the font back to
           // the original font.
       else if (result == DialogResult.Cancel)
       {
           this.Font = oldFont;
           foreach ( Control containedControl in this.Controls)
           {
               containedControl.Font = oldFont;
           }
       }
   }

   // Handle the Apply event by setting all controls' fonts to 
   // the chosen font. 
   private void FontDialog1_Apply(object sender, System.EventArgs e)
   {

       this.Font = FontDialog1.Font;
       foreach ( Control containedControl in this.Controls )
       {
           containedControl.Font = FontDialog1.Font;
       }
   }

Remarks

Every time the Apply button is clicked, another Apply event is raised.
