Hello again,
Sorry there is no very easy way of doing this but you can register for the
ItemDataBound event and set the image there, like this example:
using System;
using System.ComponentModel;
using System.Drawing;
using System.Windows.Forms;
using Telerik.WinControls.UI;
public partial class Form1 : Form
{
private RadDropDownList radDropDownList1;
public Form1()
{
InitializeComponent();
this.Controls.Add(radDropDownList1 = new RadDropDownList());
radDropDownList1.ItemDataBound += new ListItemDataBoundEventHandler(radDropDownList1_ItemDataBound);
radDropDownList1.Dock = DockStyle.Top;
}
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
radDropDownList1.DataSource = new TestsCollection();
radDropDownList1.DisplayMember = "Name";
radDropDownList1.ValueMember = "Id";
}
void radDropDownList1_ItemDataBound(object sender, ListItemDataBoundEventArgs args)
{
var test = args.NewItem.DataBoundItem as Test;
if (test == null)
{
return;
}
args.NewItem.Image = test.Image;
}
}
public class Test
{
public int Id
{
get;
set;
}
public string Name
{
get;
set;
}
public Image Image
{
get;
set;
}
public Test(int id, string name, Image image)
{
this.Id = id;
this.Name = name;
this.Image = image;
}
}
public class TestsCollection : BindingList<Test>
{
public TestsCollection()
{
this.Add(new Test(1, "Test1", Properties.Resources.ar));
this.Add(new Test(2, "Test2", Properties.Resources.ca));
}
}
Hope this helps, if you have any other questions or comments, please let me know,
Best Regards,
