Answer 2

GridViewRow drv = ((GridViewRow)(((System.Web.UI.WebControls.ImageButton)(sender)).Parent.Parent));
string version = this.GridView1.Rows[drv.RowIndex].Cells[1].Text.Trim();//这里就要看你的程序了，主要是要得到该行中的一个值，这个值能唯一标识这条记录。
下面就是用正常的sql删除，更新代码了。

Answer 3

protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
    {
       int id=GridView1.DataKeys[e.RowIndex].Value.ToString();
       //执行你的删除的操作
    }

Answer 4

 protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
    {
        //单击编辑按纽使该行为可编辑状态
        GridView1.EditIndex = e.NewEditIndex;
        
    }
    protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
    {       //写更新的操作方法
    }
    protected void GridView1_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
    {
        //取消编辑状态
        GridView1.EditIndex = -1;
       
    }

Answer 5

我刚学asp.net,对于二楼的代码看不明白，不过还是要谢谢你啊。
三楼，需要将编辑、删除按钮的ID  写成ShowEditButton，ShowDeleteButton这样吗？我有点不明白。

Answer 6

对于对BUGTOON有特殊要求的不推荐
可以用强转的方式获得每行的BUTTON按钮然后实现其click事件
