UltraComboEditor in UltraWinGrid with ValueList
posted

Hi all,

I'm using an UltraComboEditor as an editor in an UltraWinGrid to make a translation "Internal ID"  <-> "User Key". The UltraComboEditor has a DataTabe as the DataSource:

ID           Key
100        1
101        2
102        3
...            ....
201        100

Entering data:
DisplayMember     ValueMember
1              ->              100
2              ->              101
100         ->               100      WRONG
201         ->               201     WRONG

What do I have to do the only Values in the key-list are accepted and correctly translated?
DisplayMember      ValueMember
1                 ->           100
2                 ->           101
100            ->            201
201            ->            Not accepted

    Hello masch,

    A possible approach to achieve this might be by hooking to the 'BeforeCellUpdate' event and do something like the following:

    

    bool isItemInList = false;
            private void ultraGrid1_BeforeCellUpdate(object sender, Infragistics.Win.UltraWinGrid.BeforeCellUpdateEventArgs e)
            {
                foreach(ValueListItem item in ultraComboEditor1.Items)
                {
                    if(item.DisplayText == e.Cell.Text)
                    {
                        isItemInList = true;
                        break;
                    }
                }
    

                if (!isItemInList)
                {
                    e.Cancel = true;
                }
            }

    Please feel free to let me know if I misunderstood you or if you have any other questions.
