DataGridView的CellClick事件

Question

即使我們單擊DataGridView的標頭，單元格單擊事件也會被觸發。如何阻止它開火？

Answer 1

比較RowIndex和ColIndex如果它們有-1（頭列/行索引）值，那麼它就是ignore。

testDataGridView.CellClick += (senderObject, eventArgs) => 
{ 
    if (eventArgs.RowIndex == -1 || eventArgs.ColumnIndex == -1) 
    return; 
    //statements here 
}; 

Answer 2

private void DataGridView1_CellClick(object sender, DataGridViewCellEventArgs e) 
    { 
     if (e.RowIndex == -1) 
     {     
      return;     
     } 
     //Write your code here ... 
    }
