The following example shows how to display an image to the right of the Job Title column’s caption using HTML tags. The HTML formatting feature is enabled via the TreeListOptionsView.AllowHtmlDrawHeaders property.
string imageName = "customer";
imageCollection1.AddImage(Image.FromFile("c:\\customer-16x16.png"), imageName);
treeList1.OptionsView.AllowHtmlDrawHeaders = true;
treeList1.HtmlImages = imageCollection1;
colJobTitle.Caption = colJobTitle.GetCaption() + "<image=" + imageName + ">";
Dim imageName As String = "customer"
imageCollection1.AddImage(Image.FromFile("c:\customer-16x16.png"), imageName)
gridView1.OptionsView.AllowHtmlDrawHeaders = True
gridView1.HtmlImages = imageCollection1
columnCustomer.Caption = columnCustomer.GetCaption() & "<image=" & imageName & ">"
