passing c# parameter into kentico transformation

Hi

I have a CMSRepeater as follows


<cms:CMSRepeater ID="rptKeywordSearch" runat="server"  ClassNames="cms.MenuItem" Path="/%" 
            TransformationName="cms.MenuItem.SimpleList" MaxRelativeLevel="3" ZeroRowsText="">
            <HeaderTemplate>
                <ul class="keywordSearch">
            </HeaderTemplate>
            <FooterTemplate>
                </ul>
            </FooterTemplate>
        </cms:CMSRepeater>

In the transformation I am trying to read a value from the QueryString, I want to pass this into the new function I have which reads in the 'Keywords' field (csv'd values) and a search term.

The function reads the keywords field, splits out the string into an array and does a boolean check to see if the search term exists within the array, returns true if it does and false if it doesn't.


<%
string searchTerm = Request.QueryString.Get("searchtext");
%>

<li class="<%# MyFunctions.getKeyword(Eval("Keywords").ToString(), Request.QueryString.Get("searchtext"))%>"><%# GetDocumentLink() %></li>
<!--<li class="<%# MyFunctions.getKeyword(Eval("Keywords").ToString(), "car")%>"><%# GetDocumentLink() %></li>-->

The commented out line in the transformation works as expected, but now I want to dynamically pass in the search term (from the query string)

the repeater then returns values adding true or false to the class of each li

I then used CSS to hide (display:none;) on the items that have false applied. However, I have been told that this may not be acceptable for SEO and accessibility reasons.

Can anyone shed any light?

Thanks

RE:passing c# parameter into kentico transformation

Hello,

Thank you for your message.

If I understand you correctly I think you should be able to pullout the query string through our query string macro ( http://devnet.kentico.com/docs/devguide/types_of_macros.htm#querystring )

You can pullout the query string like:


{%querystring_key%}

And then pass this to your macro method.

Let me know how it works.

Kind regards,
Richard Sustek

I had tried to pass a macro into the Function.MethodName which I was trying to apply to the LI's class name, but it didn't work. I had a rethink of the task I was trying to do and I set the items that were not keywords to visible=false and rebound the repeater. It worked :)
