Hello,

I need to have the background of the drop down portion of my combobox have alternating colors. I can accomplish this with an event handler for the ItemDataBound event and a simple counter like this:

private void radComboBox1_ItemDataBound(object sender, Telerik.WinControls.UI.ItemDataBoundEventArgs e) 
i++; 
 
FillPrimitive fpOneDropDownItem = (e.DataBoundItem.Children[0] as FillPrimitive); 
fpOneDropDownItem.BackColor = (i % 2 == 0) ? ColorTranslator.FromHtml("#000000") : ColorTranslator.FromHtml("#262626"); 
fpOneDropDownItem.NumberOfColors = 1
 

I would like to get this behavior using a theme. Is it possible? I see there is an IsOdd property on the grid, is there something similar for the combobox?

Thanks,

-Gary

Hi Gary,

Thank you for the question.

Currently, the IsOdd property is only available for the RadGridView's GridRowElement. RadComboBoxItem (RadListBoxItem) does not support this feature, and it is not possible to achieve the desired behavior either by code or by using a theme. I have logged this request in our ToDo list and we will try to include this functionality in one of the future releases.

If you have additional questions, feel free to contact me.

Kind regards,
