Good day all!!! I have a combination of controls on my form (NumericUpDown, ComboBox, TextBox). The controls are bound to some data in a DataTable.

My problem is that when I change the values of any of the controls I can not move out of that particular control, either by clicking on another control or using the tab key.

I tried changing CausesValidation to false. That solved the problem of a control holding on to focus, but now the data was not being changed in the datatable.

Then I tried setting the DataSourceUpdateMode to OnPropertyChanged. This solved the problem of a control holding on to focus, and updated the value in the datatable.
However this left me with a problem when I used the mouse wheel to change a value, say in a NumbericUpDown control. If the mouse wheel is moved quickly the datatable value is updated by the control for each value change. So, say my value is 1 and I keep scrolling to 100, my form freezes until the datatable value is update 100.

Is there a better way of solving this databinding issue???
