DataGridView.RowEnter Event

Occurs when a row receives input focus but before it becomes the current row.

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

public event DataGridViewCellEventHandler RowEnter
/** @event */
public void add_RowEnter (DataGridViewCellEventHandler value)

/** @event */
public void remove_RowEnter (DataGridViewCellEventHandler value)

In JScript, you can handle the events defined by a class, but you cannot define your own.
Not applicable.

This event occurs when the DataGridView is initially loaded, as well as when the user selects a row other than the current row.

This event occurs before the CurrentRow property is updated. To retrieve the index of the newly-entered row, use the DataGridViewCellEventArgs.RowIndex property within the event handler.

For more information about handling events, see Consuming Events.

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;
    }
}
