一、在GridView中添加删除确认对话框

实现方法：
双击GridView的OnRowDataBound事件；
在后台的GridView1_RowDataBound()方法添加代码，最后代码如下所示：

    protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        //如果是绑定数据行
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
              if (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate)
            {
                ((LinkButton)e.Row.Cells[6].Controls[0]).Attributes.Add("onclick", "javascript:return confirm('你确认要删除：" + e.Row.Cells[1].Text.Trim() + "吗?')");
            }
        }

    }

另一种方法：

在GridView的RowCommand事件中添加代码

protected void GridView2_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            if (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate)
            {
             
             LinkButton btnDelete = (LinkButton)e.Row.FindControl("LinkButton1");
             btnDelete.Attributes.Add("onclick", "Javascript:return " +"confirm('Are you sure you want to delete this record " +DataBinder.Eval(e.Row.DataItem, "NewsTitle") + "')");

            }
        }
    }

protected void GridView2_RowDeleting(object sender, GridViewDeleteEventArgs e)
    {
        oa jkj=new oa();

        GridViewRow dr = GridView2.Rows[e.RowIndex];
        string id = dr.Cells[1].Text;
        string sql = "Delete from news where newsid=" +id ;
        jkj.Command(sql);//自定义类
        Bind();
    }

二、实现自动编号的方法

双击GridView的OnRowDataBound事件；
在后台的GridView1_RowDataBound()方法添加代码，最后代码如下所示：
    protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        //如果是绑定数据行
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            ////鼠标经过时，行背景色变
            //e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='#E6F5FA'");
            ////鼠标移出时，行背景色变
            //e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='#FFFFFF'");

            ////当有编辑列时，避免出错，要加的RowState判断
            //if (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate)
            //{
            //    ((LinkButton)e.Row.Cells[6].Controls[0]).Attributes.Add("onclick", "javascript:return confirm('你确认要删除：" + e.Row.Cells[1].Text.Trim() + "吗?')");
            //}

        }
        if (e.Row.RowIndex != -1)
        {
            int id = e.Row.RowIndex + 1;
            e.Row.Cells[0].Text = id.ToString();
        }

    }

注意这时最好把前台的第一列的表头该为“编号”，因为以前的第一列被“吃掉”了。
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="3" OnRowDeleting="GridView1_RowDeleting" OnRowEditing="GridView1_RowEditing"
                        OnRowUpdating="GridView1_RowUpdating" OnRowCancelingEdit="GridView1_RowCancelingEdit" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" Font-Size="12px" OnRowDataBound="GridView1_RowDataBound">

                        <Columns>

                        </Columns>

                        <SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />
                        <PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" />
                        <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />
                    </asp:GridView>
