RadCheckedDropDownList: CheckAllItem gets hidden after scrolling to the bottom and then back to the top

Use the following code snippet:

    Sub New() 
        Me.RadCheckedDropDownList1.ShowCheckAllItems = True
        Me.RadCheckedDropDownList1.AutoSizeItems = True
        For x = 1 To 20
            Dim i As New DescriptionTextCheckedListDataItem
            i.Value = x
            i.Text = x.ToString()
            i.DescriptionText = "abc def ghijkl mnop abc def ghijkl mnop" & x
    End Sub

Open the popup, scroll to the bottom and then back to the top.

Expected: The CheckAllItem is visible

Actual: The CheckAllItem is hidden

Hi, Denis,

Currently, the possible solution that I can suggest is to disable the AutoSizeItems property: 

        Me.RadCheckedDropDownList1.AutoSizeItems = False
