如何在asp.net中的gridview中编辑自动生成的列数据 [英] How to edit auto generated columns data in gridview in asp.net

问题描述

我想在asp.net中对自动生成的列执行crud操作，



我希望在单击编辑时绑定自动生成列的下拉列表linkbutton，是否可以执行这些操作。

I want to perform crud operations for "auto generated columns" in asp.net,

and i want to bind dropdownlist for auto generated columns when clicking on edit linkbutton, is it possible to perform thease operations.

推荐答案

使用Templatefield而不是boundfield



< asp：TemplateField HeaderText =Item Name>

< itemtemplate>

< asp：Label ID =itemrunat =serverText =''<％＃Bind（Itemname）％>''>



< edititemtemplate>

< asp：DropDownList ID =ddlitemname1runat =serverWidth =120px

DataSourceID =SqlDataSource2DataTextField =Itemname

DataValueField =ItemnameAutoPostBack =TrueSelectedValue =''<％＃Bind（Itemname）％> ; '' >



< asp：SqlDataSource ID =SqlDataSource2runat =server

ConnectionString =<％

Use Templatefield rather than boundfield

<asp:TemplateField HeaderText="Item Name" >
<itemtemplate>
<asp:Label ID="item" runat="server" Text=''<%# Bind("Itemname") %>''>

<edititemtemplate>
<asp:DropDownList ID="ddlitemname1" runat="server" Width="120px"
DataSourceID="SqlDataSource2" DataTextField="Itemname"
DataValueField="Itemname" AutoPostBack="True" SelectedValue=''<%# Bind("Itemname") %>''>

<asp:SqlDataSource ID="SqlDataSource2" runat="server"
ConnectionString="<%

ConnectionStrings：hospital％> SelectCommand =SELECT DISTINCT [Itemname]，[Qty] FROM [Purchaseentry]>









< HeaderStyle CssClass =headersalestylelistWidth =120px/>

< itemstyle width =120pxhorizo​​ntalalign =Center>





和



for edit

单击gridview corner并选择Enable Editing，Enable Deleting等

ConnectionStrings:hospital %>" SelectCommand="SELECT DISTINCT [Itemname],[Qty] FROM [Purchaseentry]">




<HeaderStyle CssClass="headersalestylelist" Width="120px" />
<itemstyle width="120px" horizontalalign="Center">


and

for edit
click on gridview corner and select Enable Editing, Enable Deleting etc

this.gridView.Columns[x]. any thing
