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

定義

使用者在滑鼠指標位於儲存格界限內且按著滑鼠按鈕時發生。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 

範例

下列程式碼範例示範如何使用這個成員。The following code example demonstrates the use of this member. 在此範例中, 事件處理常式會報告CellMouseDown事件的發生次數。In the example, an event handler reports on the occurrence of the CellMouseDown event. 此報表可協助您瞭解事件發生的時間, 並可協助您進行調試。This report helps you to learn when the event occurs and can assist you in debugging. 若要報告多個事件或經常發生的事件, 請考慮MessageBox.ShowConsole.WriteLine取代為, 或將訊息附加TextBox至多行。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.

若要執行範例程式碼, 請將它貼入包含名為DataGridView DataGridView1之類型實例的專案中。To run the example code, paste it into a project that contains an instance of type DataGridView named DataGridView1. 然後確定事件處理常式與CellMouseDown事件相關聯。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

備註

當使用者按下任何滑鼠按鍵時,就會發生此事件。This event occurs when the user presses any of the mouse buttons. MouseEventArgs.Button使用屬性來判斷所按的按鈕。Use the MouseEventArgs.Button property to determine which button was clicked.
