DataGridViewComboBoxColumn selection disappear Maddie from Dartford17-May-09 2:00 Maddie from Dartford 17-May-09 2:00  Hello, I am using DataGridViewComboBoxColumn as a column of DataGridView. I have assigned data source as a List<myobject> and i am able to see all values in dropdown. Now, for any Key Press it always select and display first element of list and but the selected value disappear as focus is taken away from the cell. For e.g the comboBox list contains A, B, C & D. Now user presses key 'B' then it display 'B' as expected but if user presses 'E' then it display 'A' as selected and very strangely the selection disappears as focus looses from the cell. What should i do not to display any selected value if it not in list?

(Employees can be any ICollection, ArrayList, Hashtable what not .. don't matter) Thanks dev Re: what's the diff between lock(Employees.SyncRoot) and lock(Employees)? S. Senthil Kumar17-May-09 1:04 S. Senthil Kumar 17-May-09 1:04  The SyncRoot property is used when you create synchronized collections using the .Synchronized() method. All operations on the synchronized collection lock on the object returned by the SyncRoot property. Creating synchronized collections using Synchronized() is not recommended though, because just making individual operations threadsafe usually isn't enough. Other than that, it doesn't really matter.
