I have a template column in a  radgrid.
The filter row applies any filters whenever a user enters text into any filter textbox and presses enter.

I have added a template column that has a dropdown bound to a linq to sql datasource.

It is populating just fine.  I am hocking up to the selectedindexchanged event on the dropdown when a user changes the filter item in the dropdown and it is set to autopost back.

In the selectedIndexChanged server side code (.cs)  I need to apply whatever they selected to the radgrid filters.  

What I mean by this:
  If the user has already applied a few filters before selecting a item in the dropdown. I need to append this additional filter parameter to the filterexpression of the radgrid.

Anyone aware of a good example of applying another filter and maintaining the current filters already applied.

Hello Warren,

A behavior similar to the one you need is demonstrated in the first grid from the following online example:

Filter templates

Please give it a try and let me know how if it works for your scenario.
