DataGridView.RowDividerDoubleClick 事件

定义

用户双击两行间的分隔符时发生。

public:
 event System::Windows::Forms::DataGridViewRowDividerDoubleClickEventHandler ^ RowDividerDoubleClick;
public event System.Windows.Forms.DataGridViewRowDividerDoubleClickEventHandler RowDividerDoubleClick;
public event System.Windows.Forms.DataGridViewRowDividerDoubleClickEventHandler? RowDividerDoubleClick;
member this.RowDividerDoubleClick : System.Windows.Forms.DataGridViewRowDividerDoubleClickEventHandler 
Public Custom Event RowDividerDoubleClick As DataGridViewRowDividerDoubleClickEventHandler 

事件类型

示例

下面的代码示例演示了此成员的用法。 在此示例中,事件处理程序报告事件的发生情况 RowDividerDoubleClick 。 此报表可帮助你了解事件发生的时间,并可以帮助你进行调试。 若要报告多个事件或频繁发生的事件,请考虑将 MessageBox.Show 替换为 Console.WriteLine 或将消息追加到多行 TextBox

若要运行示例代码,请将其粘贴到包含名为 DataGridView1的 类型的DataGridView实例的项目中。 然后,确保事件处理程序与 RowDividerDoubleClick 事件相关联。

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")

End Sub

注解

可以使用此事件自定义当用户双击行分隔符时发生的自动调整大小行为。

DividerWidth 属性不会扩展用户可以双击的区域。 如果使用此属性增加了分隔线的高度,则当用户双击分隔线与相邻列之间的边界时,会发生此事件。
