inline code doesn't work on a asp:Button

Question

Could someone tell me why this is happening and how to fix it if possible?

I have a button in a aspx file like:

<% foreach blah %.

orderID = GenerateCorrectOrderID();

    <input id="btnOrder"  type="button" style="background-color: #000040; color: #FFFFFF; font-weight: normal" value="Order" onclick="javascript:OpenOrderService('<%=orderID%>','A');" />


<% end foreach blah %>

The orderID is being placed correctly in the html as expected. I would like to replace the input button with a asp.button like this:

                    <asp:Button ID="btnOrder"  style="background-color: #000040; color: #FFFFFF; font-weight: normal" Text="Order"    OnClick="UpdateOrderGrid" runat="server" CausesValidation="False" Visible="False"  onclientclick="javascript:OpenOrderService('<%=#orderID%>','A');"  />

The <%=#orderID%> is not being properly placed in the html file. In fact it looks just like this: <%=#orderID%> How can I force it to inline properly?

Any idea on how I can get this to work? I really want to use a Asp.Button because I have a trigger in a update panel that it is attached to.

If it were me, I would use a repeater and databind the onclientclick instead of putting the code in your aspx/ascx file.

If you MUST do it this way, it appears you've mixed databinding syntax with inline evaluation syntax.

What I think you want is

... onclinentclick="javascript:OpenOrderService('<%= orderId %>','A');" />

那么尝试了几种不同的方法，比如java脚本类和什么不是....我决定使用一个输入按钮，我可以使用一些内联代码来定义它的id。然后我将一个asp.button放在一个不可见的div中，然后当按下输入按钮时，我会调用asp.button的click事件，这反过来会导致更新面板的触发器被触发。

我知道这是一种非常丑陋的方式，但我花了太多时间寻找更优雅的方法来实现这一目标。
