private void DataGridView1_RowDividerDoubleClick(Object sender, DataGridViewRowDividerDoubleClickEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "RowIndex", e.RowIndex );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Handled", e.Handled );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Button", e.Button );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Clicks", e.Clicks );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "X", e.X );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Y", e.Y );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Delta", e.Delta );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Location", e.Location );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "RowDividerDoubleClick Event" );
}
Private Sub DataGridView1_RowDividerDoubleClick(sender as Object, e as DataGridViewRowDividerDoubleClickEventArgs) _ 
     Handles DataGridView1.RowDividerDoubleClick

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "RowIndex", e.RowIndex)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Handled", e.Handled)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Button", e.Button)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Clicks", e.Clicks)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "X", e.X)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Y", e.Y)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Delta", e.Delta)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Location", e.Location)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"RowDividerDoubleClick Event")

注解

此事件可用于自定义当用户双击行分隔符时发生的自动调整大小行为。You can use this event to customize the automatic sizing behavior that occurs when a user double-clicks a row divider.

DividerWidth属性不会扩展在其中用户可以双击的区域。The row DividerWidth property does not extend the area in which a user can double-click. 如果已通过使用此属性增加了分隔符的高度,当用户双击分隔线与相邻的列之间的边界,会发生此事件。If the height of a divider has been increased through the use of this property, this event occurs when the user double-clicks the boundary between the divider and the adjacent column.
