jQuery Grid Plugin - jqGrid

I use two searchfilters: filterGrid and filterToolbar.

The searchFilter contains only the most general fields. The filterToolbar applies to more specific fields.

Typically I first search with searchFilter and afterwards limit the data by using the filterToolbar. This works great.

Problem:

Sometimes I want to change the searchparams of the filterGrid. When searching, the params of the filterToolbar are forgotten, I have to trigger it.

It seems that the filterToolbar knows the data from filterGrid, but contrariwise, filterGrid  ignores the filterToolbar params.

Is there a possibility that this behavior can be implemented?

If not, which solution would you suggest? I prefer one search, without triggering a second one.

Thanks in advace.
