If Val(txtFontSize.Text) > 0 Then lblGreeting.Font.Size = FontUnit.Point(Val(txtFontSize.Text)) End If ' Update the border style. pnlCard.BorderStyle = Val(lstBorder.SelectedItem.Value) ' Update the picture. If chkPicture.Checked = True Then imgDefault.Visible = True Else imgDefault.Visible = False End If ' Set the text. lblGreeting.Text = txtGreeting.Text End Sub End Class As you can see, this example limits the user to a few preset font and color choices. The code for the BorderStyle option is particularly interesting. The lstBorder control has a list that displays the text name of one of the BorderStyle enumerated values. You ll remember from the introductory chapters that every enumerated value is really an integer with a name assigned to it. The lstBorder also secretly stores the corresponding number so that the code can retrieve the number and set the enumeration easily when the user makes a selection and the cmdUpdate_Click event handler fires.

ASP .NET pages have access to the full .NET class library. With a little exploration, you ll find classes that might help the greeting-card maker, such as tools that let you retrieve all the known color names and all the fonts installed on the web server. For example, you can fill the lstFontName control with a list of fonts using the special System.Drawing.Text.InstalledFontCollection class. Here s the code you ll need: ' Get the list of available fonts, and add them to the font list. Dim fonts As New System.Drawing.Text.InstalledFontCollection() For Each family As FontFamily In fonts.Families lstFontName.Items.Add(family.Name) Next
