Question

What event to I need to handle to allow users to add “fruit” the either a valuelist or ultra dropdown.

Since it is a KVP I always get format exception

Dictionary<int,string> fruits = new Dictionary<int,string>();



 private void FruitInit()
     {
    //Create some fruit        
    fruits.Add(-1,"apple");
            fruits.Add(-2,"banana");

            //Create and add to the ultraDropDown
            UltraDropDown fruitUltraDropDown = new UltraDropDown();
            fruitUltraDropDown.DataSource = fruits.ToList();
            fruitUltraDropDown.DisplayMember = "Value";
            fruitUltraDropDown.ValueMember = "Key";
            MyUltraGrid.DisplayLayout.Bands[0].Columns["MyColumn"].ValueList = fruitUltraDropDown;
        }

What event can I handle so when a user types “grape” I can add it to the dictionary with my own key, and it gets added to the dropdownlist. Currently if I type “grape in the cell, I just get a format exception.

Got a response from Mike@infragistics, I didn’t know about ValueListResolved

Answer from Mike

There are a number of events you could
use. I would probably use
BeforeCellUpdate or maybe
BeforeExitEditMode.

Either way, what you would do is use
the ValueListResolved property on the
cell to get the ValueList and then you
can use the GetValue method to try to
find a matching item on the list. Use
the cell.EditorResolved.Text to get
the current edit text in the cell for
your search.
