Examples
The following code example illustrates how to handle this event to change the BackColor property of the cells in the current row. In this example, the background color is set in the RowEnter event, then reset to Empty on the RowLeave 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_RowEnter(object sender, 
    DataGridViewCellEventArgs e)
{
    for (int i = 0; i < dataGridView1.Rows[e.RowIndex].Cells.Count; i++)
    {
        dataGridView1[i, e.RowIndex].Style.BackColor = Color.Yellow;
    }
}
private void dataGridView1_RowLeave(object sender, 
    DataGridViewCellEventArgs e)
{
    for (int i = 0; i < dataGridView1.Rows[e.RowIndex].Cells.Count; i++)
    {
        dataGridView1[i, e.RowIndex].Style.BackColor = Color.Empty;
    }
}
Private Sub dataGridView1_RowEnter(ByVal sender As Object, _
    ByVal e As DataGridViewCellEventArgs) _
    Handles dataGridView1.RowEnter
    Dim i As Integer
    For i = 0 To dataGridView1.Rows(e.RowIndex).Cells.Count - 1
        dataGridView1(i, e.RowIndex).Style _
            .BackColor = Color.Yellow
    Next i
End Sub
Private Sub dataGridView1_RowLeave(ByVal sender As Object, _
    ByVal e As DataGridViewCellEventArgs) _
    Handles dataGridView1.RowLeave
    Dim i As Integer
    For i = 0 To dataGridView1.Rows(e.RowIndex).Cells.Count - 1
        dataGridView1(i, e.RowIndex).Style _
            .BackColor = Color.Empty
    Next i
End Sub
