右擊面板不工作

Question

private void panel1_MouseClick(object sender, MouseEventArgs e) 
     { 
      if (e.Button == MouseButtons.Right) 
      { 
       ColorDialog cd = new ColorDialog(); 
       if (cd.ShowDialog() == DialogResult.OK) 
       { 
        this.panel3.BackColor = cd.Color; 
       } 
      } 
     } 

private void panel1_MouseDown(object sender, MouseEventArgs e) 
     { 
      Panel pnl = sender as Panel; 
      if (pnl != null) 
       pnl.DoDragDrop(pnl.BackColor, DragDropEffects.Move); 
     } 


    private void panel2_DragDrop(object sender, DragEventArgs e) 
    { 
     var data = e.Data.GetData(typeof(Color)); 

     if (data != null) 
      ((Panel)sender).BackColor = (Color)data; 
    } 

    private void panel2_DragEnter(object sender, DragEventArgs e) 
    { 
     e.Effect = DragDropEffects.Move; 
    } 

我想，如果我按PANEL1應該顯示顏色選擇顏色對話框內點擊右鍵，然後我可以將PANEL1顏色拖放到是Panel2。 但這段代碼後colpetion最終拖放工作，但沒有工作panel1右鍵點擊 幫助我？

在鼠標右擊首先調用mouse down事件，因此它的，所以你試過像這樣的鼠標按下事件

private void panel1_MouseDown(object sender, MouseEventArgs e) 
     { 
      if (e.Button !=MouseButtons.Right) 
      { 

      Panel pnl = sender as Panel; 
      if (pnl != null) 
       pnl.DoDragDrop(pnl.BackColor, DragDropEffects.Move); 
      } 
     }
