您可以使用bind绑定数据库中的值

示例如下:

< pre lang ="c#">
< asp:TemplateField HeaderText ="Status" ItemStyle-Width ="100px">
< ItemTemplate>
< asp:DropDownList ID ="DropDownList1" runat ="server" SelectedValue =''<％#Bind("STATUS")％>''
Enabled ="false">
< asp:ListItem Text ="Active" Value ="1"></asp:ListItem>
< asp:ListItem Text =无效" Value ="0"></asp:ListItem>
</asp:DropDownList>
</ItemTemplate>
< EditItemTemplate>
< asp:DropDownList ID ="DropDownList1" runat ="server" SelectedValue =''<％#Bind("STATUS")％>''>
< asp:ListItem Text ="Active" Value ="1"></asp:ListItem>
< asp:ListItem Text =无效" Value ="0"></asp:ListItem>
</asp:DropDownList>
</EditItemTemplate>

< ItemStyle Width ="100px"></ItemStyle>
</asp:TemplateField></pre>

You can use bind to bind a value from database

example is given below:

<pre lang="c#">
<asp:TemplateField HeaderText="Status" ItemStyle-Width="100px">
<ItemTemplate>
<asp:DropDownList ID="DropDownList1" runat="server" SelectedValue=''<%# Bind("STATUS")%>''
Enabled="false">
<asp:ListItem Text="Active" Value="1"></asp:ListItem>
<asp:ListItem Text="Inactive" Value="0"></asp:ListItem>
</asp:DropDownList>
</ItemTemplate>
<EditItemTemplate>
<asp:DropDownList ID="DropDownList1" runat="server" SelectedValue=''<%# Bind("STATUS")%>''>
<asp:ListItem Text="Active" Value="1"></asp:ListItem>
<asp:ListItem Text="Inactive" Value="0"></asp:ListItem>
</asp:DropDownList>
</EditItemTemplate>

<ItemStyle Width="100px"></ItemStyle>
</asp:TemplateField></pre>
