使用masterpagefile时，Selectedindexchanged无法正常工作 [英] Selectedindexchanged not working correctly when masterpagefile is used

问题描述

请帮助。

使用MasterPageFile时，我的代码块无法正常工作。





它没有MasterPageFile。

如果下拉列表发生变化，则会显示gridview数据。

但是使用MasterPageFile，没有数据显示。

It似乎在下拉列表更改时回发，但无法识别SelectParameters（@KO_EGScore）。



这是我的代码

Please help.
I have a block of codes not working correctly when MasterPageFile is used.


It works without MasterPageFile.
If dropdownlist changes, the gridview data displays.
But with a MasterPageFile, no data display.
It seems posted back when dropdownlist changes, but the SelectParameters (@KO_EGScore) cannot be recognized.

Here is my code

<form id="form1" runat="server">
    <div>
    <h4>List KO Number Genes Data <asp:Label ID="Label1" runat="server" Text="" CssClass="indent small navy"></asp:Label></h4>
     <p>
         <asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True" DataSourceID="SqlDataSource1" DataTextField="KO_EGScore" DataValueField="KO_EGScore" AppendDataBoundItems="true">
             <asp:ListItem Value="">(Please select)</asp:ListItem>
         </asp:DropDownList>
         <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ws_ePathConnectionString %>" SelectCommand="SELECT DISTINCT top(10)  [KO_EGScore] FROM [b_KO_2_EGScore] ORDER BY [KO_EGScore]"></asp:SqlDataSource>
     </p>
     <p>
         <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="true" CellPadding="4"  DataSourceID="SqlDataSource2" ForeColor="#333333" GridLines="None">
            
         </asp:GridView>
         <asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:ws_ePathConnectionString %>" SelectCommand="SELECT  top(10) * FROM [b_ko_orgGenes] WHERE ([koNbr] = @KO_EGScore)">
             <SelectParameters>
                 <asp:FormParameter FormField="DropDownList1" Name="KO_EGScore" Type="String" />
             </SelectParameters>
         </asp:SqlDataSource>
     </p>
     
    </div>
    </form>

我尝试了什么：



我试过了

ClientIDMode =静态，

ScriptManager，和

AutoEventWireup =true ，

他们都没有工作。

What I have tried:

I tried the
ClientIDMode="Static",
ScriptManager, and
AutoEventWireup="true" ,
none of them worked.

使用 ControlParameter [ ^ ]而不是：

Use a ControlParameter[^] instead:

<asp:ControlParameter Name="KO_EGScore" Type="String" ControlID="DropDownList1" PropertyName="SelectedValue" />

FormParameter 正在查找具有指定名称的已发布值。将控件放在命名容器中将更改用于将值发布回服务器的名称。更改 ClientIDMode 不会对名称产生任何影响。

The FormParameter is looking for a posted value with the specified name. Putting the control in a naming container will change the name that's used to post the value back to the server. Changing the ClientIDMode won't have any effect on the name.
