GridView删除行

<asp:BoundField DataField="pid" HeaderText="节目编号" InsertVisible="False"

<ItemTemplate>
<asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="False" Text="删除" OnClientClick='<%# "if (!confirm(\"你确定要删除" + Eval("pid").ToString() + "吗?\")) return false;"%>'>
</asp:LinkButton>
</ItemTemplate> 每行后面都有删除点击删除后删除数据库编号为Eval("pid")的数据请教点击确定（怎么样判断点的确定）后后台代码怎么写？最好能给小段代码谢谢

<asp:TemplateField>
                    <ItemTemplate>
                        <asp:LinkButton ID="LinkButton1" runat="server" OnClick="LinkButton1_Click" OnClientClick="return window.confirm('确定要删除？');">LinkButton</asp:LinkButton>
                    </ItemTemplate>
                </asp:TemplateField>    protected void LinkButton1_Click(object sender, EventArgs e)
        {
            ScriptManager.RegisterStartupScript(this,this.GetType(),"","alert('你点了确定！')",true);
}
在你做数据绑定的时候就给它附上
GridViewEmp是GridView的ID
foreach (GridViewRow gvr in GridViewEmp.Rows)
                {
                    LinkButton lb = (LinkButton)gvr.FindControl("lbDelet");
                    lb.Enabled = true;
                    lb.Attributes["onclick"] = "return confirm('确定删除?')";
                }
Up
也可以设置CommandName
<asp:LinkButton ID="LinkButton1" runat="server" OnClientClick="return window.confirm('确定要删除？');" CommandName="delete" CommandArgument="<%Eval("pid")%>">LinkButton</asp:LinkButton>
if(e.CommandName="delete")
{
  int id = (int)e.CommandArgument;
  ...
}
你可以参考这种方法

怎么从后台获得当前行的pid呢？             怎么绑Eval("pid")
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
  int index=e.RowIndex ;
  GridViewRow gvr=GridView1.Rows[index];
  str1 = gvr.Cells[1].Text;
}protected void GridView1_RowDeleted(object sender, GridViewDeletedEventArgs e)
{
  if (e.Exception == null)
  Message.Text += "<br>您成功删除了"+str1 ;
  else
  Message.Text += "删除失败";
}

GridView有rowdelete和rowediting方法
protected void GridView1_RowDataBound1(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            if (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate)
            {
                ((LinkButton)(e.Row.Cells[11].Controls[1].FindControl("LinkButton2"))).Attributes["onclick"] = "if(!confirm('你确认要删除 " + e.Row.Cells[1].Text + " 吗?')) return false;";
            }
        }
    }点击删除的后台代码
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
    {
        string strsql = "delete from  room  where ID='" + GridView1.DataKeys[e.RowIndex].Value + "'";
        modify.DeleteCmd(strsql);
        gvbind();
    }
你不是在前臺用了OnClientClick 事件嗎！
OnClientClick="return confirm('确定要删除吗？')"
後臺就不需要寫啦！
RowCommand  在這個事件裏面調用刪除的方法就可以啦！
ASP代码：
<asp:TemplateField HeaderText="删除" ShowHeader="False">
                                <ItemTemplate>
                                    <asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="False" CommandName="Delete"
                                        OnClientClick="return confirm('您确定要删除该项吗？');" Text="删除"></asp:LinkButton>
                                </ItemTemplate>
然后再在GridView属性事件的RowDeleting事件添加一些Ｃ＃代码：
1.写个数据库操作类 dao ，能够直接执行 sql2.执行 dao.excutesql("delete from table where id = " + pid)3.重新绑定 gridview ,即 gridview1.databind();
但是必须设置GridView 的 DataKeyNames="id"后台：
  /// <summary>
    /// 删除
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    protected void gvMessage_RowDeleting(object sender, GridViewDeleteEventArgs e)
    {
        int id = Convert.ToInt32(gvMessage.DataKeys[e.RowIndex].Value.ToString());
        MessageManager.DelMessage(id);
        DisplayMessage();//重新绑定
    }或者：<asp:TemplateField HeaderText="删除" ShowHeader="False">
  <ItemTemplate>
  <asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="False" CommandName="del"  CommandArgument='<%# Eval("id") %>'
  OnClientClick="return confirm('您确定要删除该项吗？');" Text="删除"></asp:LinkButton>
  </ItemTemplate>后台： protected void gvNews_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        if (e.CommandName == "del")
        {
           int id =Convert.ToInt32(e.CommandArgument.ToString());
           MessageManager.DelMessage(id);
           DisplayMessage();//重新绑定        }
    }
