DataGridView.CellMouseDown DataGridView.CellMouseDown DataGridView.CellMouseDown DataGridView.CellMouseDown Event

定义

当用户在鼠标指针位于单元格边界内时按鼠标按钮时发生。Occurs when the user presses a mouse button while the mouse pointer is within the boundaries of a cell.

public:
 event System::Windows::Forms::DataGridViewCellMouseEventHandler ^ CellMouseDown;
public event System.Windows.Forms.DataGridViewCellMouseEventHandler CellMouseDown;
member this.CellMouseDown : System.Windows.Forms.DataGridViewCellMouseEventHandler 
Public Custom Event CellMouseDown As DataGridViewCellMouseEventHandler 

示例

下面的代码示例演示如何使用此成员。The following code example demonstrates the use of this member. 在此示例中, 事件处理程序报告CellMouseDown事件的发生。In the example, an event handler reports on the occurrence of the CellMouseDown event. 此报表可帮助你了解何时发生事件, 并可帮助你进行调试。This report helps you to learn when the event occurs and can assist you in debugging. 若要报告多个事件或频繁发生的事件, 请考虑MessageBox.ShowConsole.WriteLine消息替换为多行或将TextBox其追加到多行。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.

若要运行示例代码, 请将其粘贴到包含名为DataGridView DataGridView1的类型的实例的项目中。To run the example code, paste it into a project that contains an instance of type DataGridView named DataGridView1. 然后, 确保事件处理程序与CellMouseDown事件相关联。Then ensure that the event handler is associated with the CellMouseDown event.

private void DataGridView1_CellMouseDown(Object sender, DataGridViewCellMouseEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "ColumnIndex", e.ColumnIndex );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "RowIndex", e.RowIndex );
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(), "CellMouseDown Event" );
}
Private Sub DataGridView1_CellMouseDown(sender as Object, e as DataGridViewCellMouseEventArgs) _ 
     Handles DataGridView1.CellMouseDown

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "ColumnIndex", e.ColumnIndex)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "RowIndex", e.RowIndex)
    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(),"CellMouseDown Event")

End Sub

注解

当用户按下任意鼠标按钮时发生此事件。This event occurs when the user presses any of the mouse buttons. MouseEventArgs.Button使用属性可确定单击了哪个按钮。Use the MouseEventArgs.Button property to determine which button was clicked.
