Is there a way to only have the nulltext italisized?  I do not want the entered text by the user to be italisized.  This seems like it would be a pretty popular thing so it seems like there must be a way , thanks in advance.

Hello,

As far as I'm aware, it is not currently possible to change the font italics of the null text.

Hello regina,

Thank you for contacting us. You should use code to provide this functionality. Please consider the following code snippet:

private Font regularFont;
private Font italicFont;
 
public Form1()
{
   InitializeComponent();
 
   Font editorFont = this.radMaskedEditBox1.Font;
 
   this.regularFont = new Font(editorFont.FontFamily, editorFont.SizeInPoints, FontStyle.Regular);
   this.italicFont = new Font(editorFont.FontFamily, editorFont.SizeInPoints, FontStyle.Italic);
}
         
private void radMaskedEditBox1_Enter(object sender, EventArgs e)
{
   this.radMaskedEditBox1.Font = regularFont;
}
 
private void radMaskedEditBox1_Leave(object sender, EventArgs e)
{
   if (this.radMaskedEditBox1.Text.Length == 0)
   {
       this.radMaskedEditBox1.Font = italicFont;
   }
}

It's a good idea to have the fonts created once because the creation of a Font is a heavy operation and can lead to memory leaks.

I hope this will help you. If you need further assistance I would be glad to provide it.

Hi,

I've learnt something new here. Thanks.

May I suggest a slight change though. we can cut down on the number of events called and also we need to ensure that this is called from from_load as well in case the RadMaskedEditBox does not have a value when the form loads

private void radMaskedEditBox1_TextChanged(object sender, EventArgs e)
{
    if (this.radMaskedEditBox1.Text.Length == 0)
    {this.radMaskedEditBox1.Font = italicFont;}
    else
    {this.radMaskedEditBox1.Font = regularFont;}
}

and in form load
radMaskedEditBox1_TextChanged(null, null);

Hope that helps
Richard

@Ivan,
Actually, your way will fire less, and so better, but this would still need the check on load
if (this.radMaskedEditBox1.Text.Length == 0)
{
    this.radMaskedEditBox1.Font = italicFont;
}
