ASP.NET GridView模板字段无关的行为 [英] Asp.net gridview template field irrelevant behaviour

问题描述

大家好，

我正在使用C#在Asp.net中创建一个网站，我拥有一个gridview，在该gridview中，我具有用于编辑和删除记录的模板字段..
现在发生的是页面加载时，当我单击该gridview的edit或delete选项，但回发后它起作用了..

我已经使用了这段代码..

Hi everyone,

I am making a website in Asp.net using C#, i have one gridview and in that gridview i have template fields for edit and deleting records..
Now what happens is when page loads and when i click on that gridview''s edit OR delete option but after postback it works..

I have used this code..

<asp:GridView ID="gdvAssetType" runat ="server" AllowPaging="True"
                               AutoGenerateColumns="False" BackColor="White" BorderColor="#CCCCCC"
                               BorderStyle="None" BorderWidth="1px" CellPadding="3"
                               EnableModelValidation="True"
                               onpageindexchanging="gdvAssetType_PageIndexChanging"
                               onrowcommand="gdvAssetType_RowCommand" Width="747px">
                               <Columns>
                                   <asp:TemplateField HeaderText="Sr No.">
                                       <ItemTemplate >
                                           <asp:Label ID="lbSerialNo" runat ="server" Text=''<%#Container.DataItemIndex+1 %>''></asp:Label>
                                       </ItemTemplate>
                                       <ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" />
                                   </asp:TemplateField>
                                   <asp:BoundField HeaderText="Asset Type" DataField="AssetType">
                                   <ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" />
                                   </asp:BoundField>
                                   <asp:TemplateField HeaderText="Edit">
                                       <ItemTemplate >
                                            <asp:ImageButton ID="imgbtnEdit" runat ="server" CommandArgument =''<%#Eval("AssetTypeId") %>'' CommandName ="EditAssetType" ImageUrl ="../_img/ico_edit_new.gif"  CausesValidation ="false" ToolTip ="Edit Asset Type"/>
                                       </ItemTemplate>
                                       <ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" />
                                   </asp:TemplateField>
                                   <asp:TemplateField HeaderText="Delete">
                                       <ItemTemplate >
                                           <asp:ImageButton ID="imgbtnDelete" runat ="server" CommandArgument =''<%#Eval("AssetTypeId") %>'' CommandName ="DeleteAssetType"  ImageUrl ="../_img/ico_del_new_on.gif" CausesValidation ="false" OnClientClick="if (!confirm(''Do you want to delete this user ?'')) return false;"  ToolTip ="Delete Asset Type"/>
                                       </ItemTemplate>
                                       <ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" />
                                   </asp:TemplateField>
                               </Columns>
                               <FooterStyle BackColor="White" ForeColor="#000066" />
                               <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />
                               <PagerSettings Position="TopAndBottom" />
                               <PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" />
                               <RowStyle ForeColor="#000066" />
                               <SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />
                           </asp:GridView>

我的页面加载代码...

My page load code...

protected void Page_Load(object sender, EventArgs e)
   {
       try
       {
           if (Session["Username"].ToString() != "" && Session["Username"] != null && Session["Role"].ToString() != "" && Session["Role"] != null && Session.Count != 0)
           {
               if (!IsPostBack)
               {

                   FillGDVAssetTypes();
               }
           }
           else
           {
               Response.Redirect("../Login.aspx");
           }

       }
       catch { Response.Redirect("../ErrorPage/Error.aspx"); }
       finally { }
       //AssignRights();
   }

现在在删除模板"字段上单击，它首先会提示用户您是否要真正删除记录"，但是在页面加载时不起作用...编辑和删除记录都仅在回发后才起作用...

请帮帮我..

谢谢&问候，

now on delete template field click it first prompts user that "Do you want to really delete the record" , but it doesn''t works on page load ... Both edit and delete record only works after postback...

Please help me out ..

Thanks & Regards,

推荐答案

在更新或删除后的gdvAssetType_RowCommand方法中，可以调用FillGDVAssetTypes();方法重新绑定数据.

In your gdvAssetType_RowCommand method after update or delete you can call FillGDVAssetTypes(); method to rebind the data.
