I recently had to make a dropdownlist populated with fonts. Luckily, .NET allows you to use the installed fonts very easy.
First, add a drowdownlist to your ASP.NET page like this:
<asp:DropDownList runat="Server" id="ddlFonts" />
Then call this method to do the actual databinding of the fonts:
private void BindFonts()
System.Drawing.Text.InstalledFontCollection col = new System.Drawing.Text.InstalledFontCollection();
foreach (System.Drawing.FontFamily family in col.Families)
That's all there is to it. Be aware that the fonts are the ones installed on the server hosting your web page.
