How to create a delete button in GridView?

提问by Or Betzalel

I made another Column in my GridViewcalled delete. When delete is clicked, the row should be deleted or in other words, I need to get the current row's user name to delete it.

我在我的GridView删除中创建了另一个列。单击删除时，应删除该行，或者换句话说，我需要获取当前行的用户名才能将其删除。

1. Which event should I use? (RowDeleting, Rowdeleted etc...)
2. How do I get the username from the current row?

1. 我应该使用哪个事件？（RowDeleting、Rowdeleted 等...）
2. 如何从当前行获取用户名？

You can use the RowDeletingevent, by storing the user name in the data key collection you can access it programmatically.

您可以使用该RowDeleting事件，通过将用户名存储在数据键集合中，您可以以编程方式访问它。

<asp:GridView DataKeyNames="UserName" ID="GridView1" 
     runat="server" OnRowDeleting="GridView1_RowDeleting">

Then, in the code behind use the data key to delete the record.

然后，在后面的代码中使用数据键删除记录。

protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
  string userName = (string) GridView1.DataKeys[e.RowIndex].Value;
  DeleteUser(userName); 
}
