爲什麼在DataGridView中的SelectionChanged事件時CellClick事件不會觸發？

Question

dataGridView1_SelectionChanged事件觸發，當我選擇一行但dataGridView1_CellClick事件不觸發。我只使用一個網格。

private void mgInvoice_SelectionChanged(object sender, EventArgs e) 
     { 
      if (this.IsFlagForShowImage) 
      { 
       ////If show image flag is true then only show images for invoices. 
       try 
       { 
        if (this.mgInvoice.SelectedRows != null) 
        { 
         if (this.mgInvoice.SelectedRows.Count > 0) 
         { 
          invoice = this.mgInvoice.SelectedRows[0].DataBoundItem as TAPInvoice; 

         Thread th = new Thread(new ThreadStart(LoadDocumentIdByInvoice)); 
         th.Start(); 

         this.ShowInvoiceImageDocumentByDocId(this.invoice); 
         IsModifiedCollection = true; 

         //Zahid 
         this.SetPriviliges(); 
        } 
       } 
      } 
      catch 
      { 
       throw; 
      } 
      finally 
      { 

      } 
     } 
    } 

上述事件正確着火。但下面提到的事件不會引發火災。

private void mgInvoice_CellClick(object sender, DataGridViewCellEventArgs e) 
     { 
      if (this.mgInvoice.Columns["FImagesReviewed"].Visible) 
      { 
       this.mgInvoice.Columns["FImagesReviewed"].Visible = true; 

      } 
     else if (this.mgInvoice.Columns["FImagesApproved"].Visible) 
     { 
      this.mgInvoice.Columns["FImagesApproved"].Visible = true; 
     } 
    }

我有同樣的問題。有一個分配到DataGridView的SelectionChanged事件處理程序的CurrentCell：

_DataGridView.CurrentCell = cellToSelect; 

之後，我刪除了此任務的CellClick事件再次被解僱。
