DataGridView的CellClick事件

Question

即使我们单击DataGridView的标题，单元格单击事件也会被触发。如何阻止它开火？

Answer 1

比较RowIndex和ColIndex，如果它们的值为-1（标题列/行索引），则为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 ...
    }
