从数据库绑定下拉列表 [英] bind dropdown from database

问题描述

我在asp.net中更新鲜。

i在网格中有一个下拉列表，里面有列表项。



i不能绑定值使用Gridview.Databind（）中的itemtemplate中的数据库



这里是我的下拉列表

i am fresher in asp.net.
i have a dropdownlist in grid with list items in it.

i cant bind the values from database in itemtemplate while using Gridview.Databind()

here is my dropdownlist

<pre lang="HTML">
<asp:DropDownList ID="DropDownList3"   runat="server" Height="16px" Width="53px" SelectedValue='<%# Bind("EdnLevel") %>' >
<asp:ListItem Selected="True">Nos</asp:ListItem>
<asp:ListItem>Kg</asp:ListItem>
<asp:ListItem>Ltr</asp:ListItem>

</asp:DropDownList>

推荐答案

<asp:dropdownlist id="DropDownList3" runat="server" height="16px" width="53px" selectedvalue="<%# Bind("EdnLevel") %>" xmlns:asp="#unknown">
<asp:listitem>Nos</asp:listitem>
<asp:listitem>Kg</asp:listitem>
<asp:listitem>Ltr</asp:listitem>
 
</asp:dropdownlist>

and now you have to find the dropdownlist within grid
on rowdatabound event
eg.

dropdownlist objddl=(dropdownlist)grid1.rows[rowindex].fincontrol["dropdownlist id"];
objddl.SelectedValue="Assiged The Data What U Want"
