SharePoint - Dynamically Setting a property on a webpart. Possible with inline C# code block ? or Javascript?

I want to dynamically set the FilterValue1 property of a Content by Query to the querystring IDs value.

I tried to do it with an inline embed FilterValue1="<%= Reponse.Write .. but no luck

Without having to code my own webpart, any way to change the property value with a small C开发者_如何学Go# code block on the aspx page?

How about with javascript?

Thank you!
