内联代码不适用于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.

Answer 1

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');" />

Answer 2

Well after trying several different ways like with java script classes and what not....I decided to use a input button which I could use some inline code to define it's id. I then put a asp.button inside a invisible div and then when the input button was pushed I would call the click event of the asp.button which in turn would cause the trigger of the update panel to fire off.

I know this is a very ugly way to do it but I spent way too much time looking for a more elegant way to accomplish this.
