<%= _s_Variable %> not working

I have all my images in a directory called "images/Red". They are all the same color and
look the same way. They are all called like the following code:


<asp:ImageButton ID="cmdSave" runat="server" ImageUrl="~/images/Red/Save.jpg"
AlternateText="Save" />


Now some users are complaining they can't see them clearly but some users want them to
stay that color (Red). No problem I thought. I created Blue buttons and put them in
another directory called "images/Blue".


I have _s_CSS_Btn_DWhr as a friend variable "Red". (The default.) I thought the
following would work in the ascx but it doesn't.


<asp:ImageButton ID="cmdSave" runat="server" ImageUrl="~/images/<%= _s_CSS_Btn_DWhr
%>/Save.jpg" AlternateText="Save" />

Instead of substitues "Red" for <%= _s_CSS_Btn_DWhr %> the processor writes
%3C%25=%20_s_CSS_Btn_DWhr%20%25%3E


Can someone tell me what I am doing wrong?

Thanks

Try

<asp:ImageButton ID="cmdSave" runat="server" ImageUrl="<%= "~/images/"
& _s_CSS_Btn_DWhr & "/Save.jpg" %>" AlternateText="Save" />

if it's on c# then use + instead of &

Using <% %> inside a control won't necessarily work. Instead, you can set
cmdSave.ImageUrl in the Page_Load handler.

Andrew, you're right, please ignore my post...

Jennifer, either assign url in the code behind, or add in top of your
page

<script language="VB" runat="server">
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs)
cmdSave.ImageUrl = "~/images/" & _s_CSS_Btn_DWhr & "/
Save.jpg"
End Sub
</script>

and then it should work.
 
Wow. I have to change probably a couple of hundred of these and doing this in the code
behind really is terrible. I was really hoping I could do this with a search & replace
for all the ascx pages. Of well. Thanks for the replies.

Another option could be converting ASP.NET control into HTML input
control

<input type="image" src='<%"/images/" & _s_CSS_Btn_DWhr & "/Save.jpg"
%>' />

which could act the same as ImageButton

You could write a program to do it...

Actually, I just had to use the hyperlink HTML control (non ASP.Net one) to get around a
problem. 99% of the time MS out-thinks us in a good way. But in that 1% of the time,
what a pain-in-the-neck programming can be.

I am going to play with this idea. There might be some problems with this because there
is quite a bit of onClientClick stuff in there.

Thanks again to everyone.

What you can also do is to try to use themes and skins. Because
personalization is exactly what they were designed for.
