请尝试以下操作，请注意，这还需要您将DropDownList绑定到另一个SqlDataSource，它将显示该列中的所有值：
<asp:TemplateField HeaderText="EddlA Name" SortExpression="eddlAname">
<EditItemTemplate>
<asp:DropDownList ID="eddlAname" runat="server" Text='<%# Bind("eddlAname") %>' CssClass="form-control" RenderMode="Lightweight"
DataSourceID="SqlDataSource2" AppendDataBoundItems="true" DataTextField="eddlAname" DataValueField="eddlAname" BackColor="Transparent"></asp:DropDownList>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="LBLeddlAname" runat="server" Text='<%# Bind("eddlAname") %>' ReadOnly="true" BackColor="Transparent" ForeColor="Black"></asp:Label>
</ItemTemplate>
</asp:TemplateField>
然后，您的其他SqlDataSource看起来将类似于绑定eddlAname列。
<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:CobornSalesDBConnectionString %>"
SelectCommand="SELECT DISTINCT [eddlAname] FROM [EntityNameHere]"></asp:SqlDataSource>
