Hi Mike,

Thank you for checking.

The workaround works fine for me.

Thank you.

Hi Dirk,

I created a small test project to try this out and I am getting the same results. It looks like the CheckState on the other items is actually changing, but the display is just not refreshing. So when you close the dropdown and re-open it, it's correct.

But this is clearly a bug. I'm going to forward this on to Infragistics Developer Support so they can get it corrected.

In the mean time, you can work around it by forcing the list to refresh:

        void checkedItemList_CheckStateChanged(object sender, EditorCheckedListSettings.CheckStateChangedEventArgs e)
        {
            ValueList valueList = sender as ValueList;
            if (valueList == null)
                return;

            ValueListItem selectedItem = e.Item as ValueListItem;
            if (selectedItem == null)
                return;

            if (selectedItem.DataValue.ToString() == "Any" && selectedItem.CheckState == CheckState.Checked)
            {
                foreach (ValueListItem valueListItem in valueList.ValueListItems)
                {
                    if (valueListItem != selectedItem)
                        valueListItem.CheckState = CheckState.Unchecked;                        
                }
            }

            IUltraControlElement valueListDropDown = DropDownManager.GetCurrentDropDownControl(valueList.Owner.Control) as IUltraControlElement;
            if (valueListDropDown != null)
                valueListDropDown.MainUIElement.DirtyChildElements(true);
        }

Thanks Mike,

This works for me.

Kumar
