How to pass a query string with ASP.NET hyperlink

Question

I am trying to pass an ID as a query string to another page. this is the hyper link code:

<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='../request/inforequest.aspx?ID=     + <%# Eval(ID) %>' Target='_BLANK' Text='Request a Showing' alt='Request a Showing' border='0'
                                CssClass="btn btn-primary"></asp:HyperLink>

This is the resulting url:

http://localhost:51378/request/inforequest.aspx?ID=%20+%20<%# Eval(ID) %>

It is passing the id, 20 is the correct value in this case but it only adds it where there are spaces, I dont understand what is happening here can someone please help?

it's not passing the id 20, it's passing %20 which is a encoded space character... — bastos.sergio

This should work correctly

<asp:hyperlink runat="server" navigateurl='<%# string.Concat("../request/inforequest.aspx?ID=", Eval("ID"))%>' target="_blank" Text="Click Here" />

Try this?

<asp:HyperLink ID="HyperLink1" runat="server" 
    NavigateUrl='~/request/inforequest.aspx?ID=<%# Eval("ID") %>' target="_blank" 
    Text="Request a Showing" alt="Request a Showing" border="0"
    CssClass="btn btn-primary">
</asp:HyperLink>

same thing as above, it just passes <%# Eval(ID) %> to the url. I've tried all manner of combinations of quotes and i either get a This tag is not well formed error or it just wont evaluate the Eval

What specific error did you get with this version, and what link was generated in the output?

adgoodso23 Over a year ago

this was the URL localhost:51378/request/inforequest.aspx?ID=<%# Eval(ID) %>

i add double quotes around ID in the Eval and the syntax highlighting seemed to recognize it but then i get a parser error The server tag is not well formed.

The reason you got the error is because you can't have two sets of similar quote types for a single attribute value.
