GridView RowCommond事件请求解答

Question

各位：
   请教一个GridView RowCommond事件的问题
背景：我在GridView中增加了一个模板列，里面增加了一个按钮
问题：
1.如果我增加的控件为Button，则无法触发RowCommond事件，为什么？
2.如果增加的控件为LinkButton，则可以触发RowCommond事件，但是无法执行RowCommond事件中的Page.ClientScript.RegisterStartupScript，JS无效代码如下(GridView中已经增加了RowCommon的事件调用)：
aspx端代码：
onrowcommand="GridReportList_RowCommand"<asp:TemplateField HeaderText="操作" ShowHeader="False">
                                          <ItemTemplate>
                                            <asp:LinkButton ID="btnRowConfirm" runat="server" Text="结果确认" CommandName="ConfirmResult"/>
                                          </ItemTemplate>
                                          <ItemStyle HorizontalAlign="Center" />
                                     </asp:TemplateField>CS端代码：
protected void GridReportList_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        if (e.CommandName == "ConfirmResult")
        {
            Page.ClientScript.RegisterStartupScript(this.GetType(), "myscript", "alert('ddddd');", true);
        }
    }

Answer 1

 protected void GridReportList_RowCommand(object sender, GridViewCommandEventArgs e)
        {
            if (e.CommandSource.GetType() == typeof(LinkButton) && e.CommandName == "ConfirmResult")
            {
                this.ClientScript.RegisterStartupScript(GetType(), "", "<script>alert('ddddd');</script>");
            }
        }

Answer 2

this.ClientScript.RegisterStartupScript(GetType(), "", "<script>alert('ddddd');</script>");
这句话，我单步调试是可以运行的，只是没有出现结果。

Answer 3

有，用的AJAX控件
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
                         <ContentTemplate>
                             <asp:Timer ID="Timer1" runat="server" Interval="120000">
                             </asp:Timer>
                             <asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server" CombineScripts="false">
                             </asp:ToolkitScriptManager>
                             <asp:GridView ID="GridReportList" runat="server" AutoGenerateColumns="False" 
                                 BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" 
                                 CellPadding="3" 
                                 DataKeyNames="EQPID,BUYOFFRESULT,BUYOFFSTARTTIME,BUYOFFENDTIME,LOTID,ALUMINIUMTHICKNESS,FLAG,WIRE" 
                                 OnRowCreated="GridReportList_RowCreated" 
                                 Width="100%" onrowdatabound="GridReportList_RowDataBound"  
                                 AllowSorting="True" onsorting="GridReportList_Sorting" 
                                 onrowcommand="GridReportList_RowCommand">
                                 <FooterStyle BackColor="White" ForeColor="Black" />
                                 <RowStyle BackColor="#F8F8F8" />
                                 <PagerStyle BackColor="#F8F8F8" ForeColor="Red" HorizontalAlign="Left" />
                                 <SelectedRowStyle CssClass="mover" />
                                 <HeaderStyle CssClass="toptrbg" />
                                 <AlternatingRowStyle BackColor="White" />
                                 <Columns>
                                     <asp:BoundField DataField="EQPID" HeaderText="设备号"   SortExpression="EQPID">
                                         <ItemStyle HorizontalAlign="Center" />
                                     </asp:BoundField>
                                     <asp:BoundField DataField="LOTID" HeaderText="批号" SortExpression="LOTID">
                                         <ItemStyle HorizontalAlign="Center" />
                                     </asp:BoundField>
                                     <asp:BoundField DataField="BUYOFFRESULT" HeaderText="Buy Off结果"   SortExpression="BUYOFFRESULT">
                                         <ItemStyle HorizontalAlign="Center" />
                                     </asp:BoundField>
                                     <asp:BoundField DataField="BUYOFFSTARTTIME" HeaderText="Buy Off开始时间" SortExpression="BUYOFFSTARTTIME">
                                         <ItemStyle HorizontalAlign="Center" />
                                     </asp:BoundField>
                                     <asp:BoundField DataField="BUYOFFENDTIME" HeaderText="Buy Off结束" SortExpression="BUYOFFENDTIME">
                                         <ItemStyle HorizontalAlign="Center" />
                                     </asp:BoundField>
                                     
                                     <asp:TemplateField HeaderText="操作" ShowHeader="False">
                                          <ItemTemplate>
                                            <asp:LinkButton ID="btnRowConfirm" runat="server" Text="结果确认" CommandName="ConfirmResult"/>
                                          </ItemTemplate>
                                          <ItemStyle HorizontalAlign="Center" />
                                     </asp:TemplateField>                                     
                                 </Columns>
                             </asp:GridView>
                      </ContentTemplate>
                     </asp:UpdatePanel>

Answer 4

我用的IE6和360，会不会是用了AJAX控件的问题？但是除开GridView之外的按钮触发后都可以执行的
例如下面这句就可以执行
protected void btnresultaffirm_Click(object sender, EventArgs e)
    {
        Page.ClientScript.RegisterStartupScript(this.GetType(), "myscript", "showdiv('');", true);
            }

Answer 5

页面上有很多控件，不止一个GridView，现在是GridView中的按钮无法触发Page.ClientScript.RegisterStartupScript

Answer 6

 Page.ClientScript.RegisterStartupScript(this.GetType(), "myscript", "<script>showdiv('');</script>", true);
这样看行不行。

Answer 7

是updatepanel 的关系用ScriptManager.RegisterStartupScript(UpdatePanel1, UpdatePanel1.GetType(), "alertScript", "alert('ddddd');",  true);

Answer 8

厉害！没错，OK了，THKS
这个帖子还有一个问题：如果我增加的控件为Button，则无法触发RowCommond事件，为什么？

Answer 9

也就是模板中用Button控件，触发不了RowCommond
<asp:TemplateField HeaderText="操作" ShowHeader="False">
                                          <ItemTemplate>
                                            <asp:Button ID="btnRowConfirm" runat="server" Text="结果确认" CommandName="ConfirmResult"/>
                                          </ItemTemplate>
                                          <ItemStyle HorizontalAlign="Center" />
                                     </asp:TemplateField>

Answer 10

你可以这样写：
前台：<asp:TemplateField HeaderText="删除">
                <ItemTemplate>
                    <asp:ImageButton ID="ImageButton1" runat="server" ImageUrl="~/images/post_button_delete.gif" OnClientClick="javascript:return confirm('确实要删除吗？')" CommandName="MyDelete"  CommandArgument='<%#Eval("ID") %>' />
                </ItemTemplate>
            </asp:TemplateField>后台在RowCommand事件中这样写：protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        if (e.CommandName == "MyDelete")
        {
            string ID = e.CommandArgument.ToString();
            sqlString = "delete from tb_Standard where ID='" + ID + "'";
            if (dp.updateData(sqlString) > 0)
            {
                Response.Write("<script> alert('删除成功！');window.location.href='StandardM.aspx' </script>");
            }
            else
            {
                Response.Write("<script> alert('删除失败！') </script>");
            }
            GridView1.DataBind();
        }
    }基本上就没什么问题了，你可以试一下
