如何响应gridview的特定按钮事件 [英] how to respond to gridview's specific button event

问题描述

我有一行网格视图。 Row包含Combobox文本框和两个按钮。

现在我想处理在gridview里面的Button事件我正在使用它。

I have a a gridview with one row. Row Contain Combobox text box and two button.
now i want to work on Button event which is inside of gridview i am using this .

if (e.RowIndex >= 0 && ((DataGridView)sender).Columns[e.ColumnIndex].GetType() == typeof(DataGridViewButtonColumn))
   {
      DataGridViewRow row = (DataGridViewRow)dataGridView1.Rows[0].Clone();
      dataGridView1.Rows.Add(row);

      MessageBox.Show(e.ColumnIndex.ToString()+' '+e.RowIndex);
   }

工作正常，但问题是;它正在处理按钮单击事件。另外，当我尝试在文本框中写入时（在gridview内部），它也会起火。

It working fine but the problem is; it is working on both button click event. plus as i try to write in textbox (which inside of gridview) it also get fire.

推荐答案

您可以通过列索引进行限制：如果您的按钮位于第五列，例如，它的索引是4.所以，而不是：

You could restrict by the column index: if your button is on the fifth column, for example, it's index is 4. So, instead of:

if (e.RowIndex >= 0 && ((DataGridView)sender).Columns[e.ColumnIndex].GetType() == typeof(DataGridViewButtonColumn))

你可以写：

you can write:

if (e.RowIndex >= 0 && e.ColumnIndex == 4)

每当修改列的索引时，都必须更改代码，这是不方便的。

With the inconvenient that you have to change your code whenever you modify the index of the column.
