Quick Start

C#:

csharp

using Syncfusion.Windows.Forms.Tools;

FontListBox fontListBox1 = new FontListBox();
fontListBox1.Size = new System.Drawing.Size(160, 94);
fontListBox1.UseAutoComplete = true;
fontListBox1.SelectionMode = System.Windows.Forms.SelectionMode.One;
fontListBox1.SelectedIndexChanged += FontListBox1_SelectedIndexChanged;
this.Controls.Add(fontListBox1);

private void FontListBox1_SelectedIndexChanged(object sender, EventArgs e)
{
    label1.Font = new System.Drawing.Font(
        fontListBox1.SelectedItem.ToString(), 11, System.Drawing.FontStyle.Regular);
}

VB.NET:

Imports Syncfusion.Windows.Forms.Tools

Dim fontListBox1 As New FontListBox()
fontListBox1.Size = New System.Drawing.Size(160, 94)
fontListBox1.UseAutoComplete = True
fontListBox1.SelectionMode = System.Windows.Forms.SelectionMode.One
AddHandler fontListBox1.SelectedIndexChanged, AddressOf FontListBox1_SelectedIndexChanged
Me.Controls.Add(fontListBox1)

Private Sub FontListBox1_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs)
    label1.Font = New System.Drawing.Font(
        fontListBox1.SelectedItem.ToString(), 11, System.Drawing.FontStyle.Regular)
End Sub
