In the event handler for CellValueChanged, for a certain condition, I want the focus to stay in the cell and clear its content. What's happening is focus (cursor) is in the next cell when the handler finishes its work. It needs to be in the same cell that caused the event. MyGrid.CellValueChanged -= new DataGridViewCellEventHandler(Cell...
Some event handlers for the WinForm DataGridView have DataGridViewCellEventArgs as a parameter and a ColumnIndex as a property of that argument.

How can I achieve this since the paint events are on...
I am setting the width of a WinForm datagridview column to 140 and I am checking the width and it's 100. The grid is wide enough to make all columns wider. Why isn't the column accepting the 140 value? Is there a setting which controls the max width? MyGrid.Columns["Name"].Width = 140; int i = MyGrid.Columns["Name"].Width; //why is i = ...
