Examples

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.

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;
}

Private Sub dataGridView1_CellEnter(ByVal sender As Object, _
    ByVal e As DataGridViewCellEventArgs) _
    Handles dataGridView1.CellEnter

    dataGridView1(e.ColumnIndex, e.RowIndex).Style _
        .SelectionBackColor = Color.Blue

End Sub

Private Sub dataGridView1_CellLeave(ByVal sender As Object, _
    ByVal e As DataGridViewCellEventArgs) _
    Handles dataGridView1.CellLeave

    dataGridView1(e.ColumnIndex, e.RowIndex).Style _
        .SelectionBackColor = Color.Empty

End Sub

Remarks

This event may occur twice for a single click if the control does not have input focus and the clicked cell was not previously the current cell.
