DataGridView.CellLeave Event

.NET Framework 2.0

Note: This event is new in the .NET Framework version 2.0.

Occurs when a cell loses input focus and is no longer the current cell.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

C#
C++
VB
Copy 
public event DataGridViewCellEventHandler CellLeave
J#
Copy 
/** @event */
public void add_CellLeave (DataGridViewCellEventHandler value)

/** @event */
public void remove_CellLeave (DataGridViewCellEventHandler value)
JScript
Copy 
JScript supports the use of events, but not the declaration of new ones.

For more information about handling events, see Consuming Events.

The following code example illustrates how to handle this event to change the SelectionBackColor property of the current cell. In this example the selection background color is set in the CellEnter event, then reset to Empty on the CellLeave event. To run this example, paste the code into a form that contains a DataGridView named dataGridView1 and ensure that all events are associated with their event handlers.

C#
VB
Copy 
private void dataGridView1_CellEnter(object sender, 
    DataGridViewCellEventArgs e)
{
    dataGridView1[e.ColumnIndex, e.RowIndex].Style
        .SelectionBackColor = Color.Blue;
}

private void dataGridView1_CellLeave(object sender, 
    DataGridViewCellEventArgs e)
{
    dataGridView1[e.ColumnIndex, e.RowIndex].Style
        .SelectionBackColor = Color.Empty;
}

Why is it that the value of the Cell is not set correctly before this event?

If I enter a cell (it happens to be a comboBox cell) and select a value, then leave, when this event fires the value of the cell is still null. Why? and what event can I handle that happens when the user leaves the cell, but will let me know the value of the cell?
