    I'm trying to create listbox items programatically and have been so far completely unable to set the back color of the listbox items or to turn the borders on for all listboxitems. Please help.

            // Method to set default ListItem properties 
            private RadListBoxItem newListItem(string displayText, int ID, GMapMarker marker) 
                RadListBoxItem item = new RadListBoxItem(); 
                item.ImageAlignment = ContentAlignment.MiddleLeft; 
                item.TextImageRelation = TextImageRelation.ImageBeforeText; 
                if (marker is JobMarker) 
                    item.Image = (Image)Properties.Resources.ResourceManager.GetObject(((JobMarker)marker).IconFileName); 
                    if (!((JobMarker)marker).IsGeoCoded) 
                        item.BackColor = Color.LightPink; 
                else if (marker is EmployeeMarker) 
                    item.Image = (Image)Properties.Resources.ResourceManager.GetObject(((EmployeeMarker)marker).IconFileName); 
                    if (!((EmployeeMarker)marker).isGeoCoded) 
                        item.BackColor = Color.LightPink; 
                item.Text = displayText; 
                item.Tag = ID; 
                return item; 

    This is the code I am using to create the listboxitem

    Hello Versile,

    Thank you for contacting us.

    The RadListBoxItem is built from a FillPrimitive and a BorderPrimitive. These control the appearance of the item. So instead of setting the RadListBoxItem itself, you will need to set specific properties of the appropriate primitive. Here is a sample snippet that illustrates this approach:

    FillPrimitive fp = ((FillPrimitive)radListBoxItem1.Children[0]);
    fp.BackColor = Color.Pink;
    fp.BackColor2 = Color.Orange;
    fp.BackColor3 = Color.Yellow;
    fp.BackColor4 = Color.Red;
    fp.NumberOfColors = 4;
    fp.GradientStyle = Telerik.WinControls.GradientStyles.Linear;
    BorderPrimitive bp = (BorderPrimitive)radListBoxItem2.Children[1];
    bp.ForeColor = Color.Pink;
    bp.ForeColor2 = Color.Orange;
    bp.ForeColor3 = Color.Yellow;
    bp.ForeColor4 = Color.Red;
    bp.BoxStyle = Telerik.WinControls.BorderBoxStyle.SingleBorder;
    bp.GradientStyle = Telerik.WinControls.GradientStyles.Linear;

    I hope this is helpful. Let me know if you have further questions.

    Kind regards,
    the Telerik team
