Adding items programmatically
Updated over 6 months ago
RadButtonTextBox supports adding items at run time, which means that you can manually populate it with data. The following examples demonstrate how to add different button elements to the RadButtonTextBox's RightButtonItems and LeftButtonItems collections.

Add button elements programmatically
C#
Dictionary<int, string> glyphs = new Dictionary<int, string>();
List<RadButtonElement> buttons = new List<RadButtonElement>();
glyphs.Add(0, ""); //yammer
glyphs.Add(1, ""); //twitter
glyphs.Add(2, ""); //pinterest
glyphs.Add(3, ""); //google
glyphs.Add(4, ""); //facebook
glyphs.Add(5, ""); //linkedin
glyphs.Add(6, "\ue817"); //Reddit
glyphs.Add(7, "\ue81d"); //Tumbler
glyphs.Add(8, "\ue813"); // MySpace

RadButtonElement radButtonElement = new RadButtonElement();
radButtonElement.DisplayStyle = Telerik.WinControls.DisplayStyle.Text;
radButtonElement.TextElement.CustomFont = "TelerikWebUI";
radButtonElement.TextElement.CustomFontSize = 10;
radButtonElement.TextElement.TextRenderingHint = System.Drawing.Text.TextRenderingHint.AntiAlias;
radButtonElement.Text = glyphs[i];
buttons.Add(radButtonElement);
}
radButtonTextBox1.RightButtonItems.AddRange(buttons[0], buttons[1], buttons[3], buttons[4]);
radButtonTextBox1.LeftButtonItems.AddRange(buttons[5], buttons[6], buttons[7], buttons[8]);
radButtonTextBox1.AutoSize = false;
radButtonTextBox1.Text = "";
The following code snippet demonstrates how to add programmatically different types of elements in RadButtonTextBox:

{

}
private void RadForm1_Load(object sender, EventArgs e)
