DataGridViewRowsAddedEventArgs.RowIndex Property

Gets the index of the first added row.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public int RowIndex { get; }

Property Value

Type: System.Int32
The index of the first added row.

When the user adds a new row using the row for new records, the value of this property is equal to the index of the new location of the row for new records, which is one greater than the row just added. When you add rows programmatically, however, the value of this property is the index of the first row added.

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the DataGridView.RowsAdded event. This report helps you to learn when the event occurs and can assist you in debugging. To report on multiple events or on events that occur frequently, consider replacing MessageBox.Show with Console.WriteLine or appending the message to a multiline TextBox.

To run the example code, paste it into a project that contains an instance of type DataGridView named DataGridView1. Then ensure that the event handler is associated with the DataGridView.RowsAdded event.

private void DataGridView1_RowsAdded(Object sender, DataGridViewRowsAddedEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "RowIndex", e.RowIndex );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "RowCount", e.RowCount );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "RowsAdded Event" );
}
