Exceptions

ArgumentException

The specified cell when setting this property is not in the DataGridView.

InvalidOperationException

The specified cell when setting this property has a RowIndex or ColumnIndex property value of -1, indicating that it is a header cell or a shared cell.

-or-

The specified cell when setting this property has a Visible property value of false.

Examples

The following code example illustrates how to ensure that the current cell is visible after sorting. This code works only with an unbound DataGridView control. With a DataGridView control bound to an external data source, the current cell is not automatically persisted when sorting.

To run this example, paste the following code into a form that contains a DataGridView named dataGridView1. In C#, you must also connect the Sorted event to the event handler.

private void dataGridView1_Sorted(object sender, EventArgs e)
{
    this.dataGridView1.FirstDisplayedCell = this.dataGridView1.CurrentCell;
}

Private Sub dataGridView1_Sorted(ByVal sender As Object, _
    ByVal e As System.EventArgs) Handles dataGridView1.Sorted

    Me.dataGridView1.FirstDisplayedCell = Me.dataGridView1.CurrentCell

End Sub

Remarks

You can use this property to determine which cell is in the first row and column currently displayed in the control. Typically, this is in the upper left corner, but for right-to-left languages, it is in the upper right corner. You can also set this property to scroll the control to the indicated cell.
