How does the CheckedDropDownList control use DescriptionTextListDataItems?

[yw]

I introduced the function that the CheckedDropDownList control can use DescriptionTextListDataItems on https://www.telerik.com/products/winforms/checkeddropdownlist.aspx, but I didn't find any sample code. Only the DropDownList uses DescriptionTextListDataItems. How should the CheckedDropDownList control use DescriptionTextListDataItems?

Hello,

Yes, RadCheckedDropDownList features DescriptionTextListDataItems, which provide an additional element to hold description text. DescriptionTextCheckedListDataItem is similar to the RadCheckedListDataItem and should be added to the Items collection. You need to create an instance of DescriptionTextCheckedListDataItem, set its DescriptionText, and add it to the collection of items. For example:

DescriptionTextCheckedListDataItem descriptionItem = new DescriptionTextCheckedListDataItem();
descriptionItem.Text = "Chicken wings";
descriptionItem.DescriptionText = "description here";
radCheckedDropDownList1.Items.Add(descriptionItem);

More information about how to add items in RadCheckedDropDownList is available in our online documentation here: Adding Items Programmatically - RadCheckedDropDownList - Telerik UI for WinForms
