Property Value

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;
    }
}

private void button1_Click(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.set_FontMustExist(true);
    // Associate the method handling the Apply event with the event.
    fontDialog1.add_Apply(new System.EventHandler(fontDialog1_Apply));
    // Set a minimum and maximum size to be
    // shown in the FontDialog.
    fontDialog1.set_MaxSize(32);
    fontDialog1.set_MinSize(18);
    // Show the Apply button in the dialog.
    fontDialog1.set_ShowApply(true);
    // Do not show effects such as Underline
    // and Bold.
    fontDialog1.set_ShowEffects(false);
    // Save the existing font.
    System.Drawing.Font oldFont = this.get_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.Equals(get_DialogResult().OK)) {
        fontDialog1_Apply(this.button1, new System.EventArgs());
    }
    // If Cancel is clicked, set the font back to
    // the original font.
    else {
        if (result.Equals(get_DialogResult().Cancel)) {
            this.set_Font(oldFont);
            for (int iCtr = 0; iCtr < this.get_Controls().get_Count();

                    get_Item(iCtr);
                containedControl.set_Font(oldFont);
            }
        }

    this.set_Font(fontDialog1.get_Font());
