I want to make a combobox in a c# .NET 4.5 Windows Forms application (note: not WPF) that displays all the truetype installed font on the system and that every font is form
You can achieve this by following a project published couple of years ago here, https://www.codeproject.com/Articles/318174/Creating-a-WYSIWYG-font-ComboBox-using-Csharp
But instead of doing that, you can follow the Narek Noreyan steps and adding more, use a rich text box, whose text font will be changed after selecting a font family from the combo box.
Some code snippet here,
using System.Drawing.Text;
void mainformload(object sender, EventArgs s)
{
InstalledFontCollection inf=new InstalledFontCollection();
foreach(Font family font in inf.Families)
combobox.Items.Add(font.Name); //filling the font name
//get the font name of the rich text box text
combobox.Text=this.richtextbox.Font.Name.ToString();
}
void comboboxselectionchanged(object sender, EventArgs e)
{
richtextbox.Font=new Font(combobox.text, richtextbox.Font.Size);
}
