I need to solve the following requirement:

The users of my jqgrid would like to be able to save the current state of the jqgrid filter so that it can be reloaded later. I have looked around on the web and found people with similar requirements. The first thing I tried was to use this to fetch the filter state:

var filter = cloneObject($("#MyGrid").getGridParam("postData"));

, and this to reload it:

$("#MyGrid").setGridParam(null);
$("#MyGrid").setGridParam(filter);
$("#MyGrid").trigger("reloadGrid");

This partly worked: If I set a filter value in the filter toolbar and saved it, it would be active when I reload it, but here is what's not working:

1: It does not seem to load the advanced filters (filter dialog box). Only toolbar filter is loaded

2: Row ordering is not loaded

3: It does not populate the toolbar textboxes with the values. So if I load a filter with "ID=32", I would like the text box for the ID column in the filter toolbar to say "32" so you know what filter is currently active.

So my question is: Am I on the right track with using get/setGridParam for this functionallity? When I look at the filter object that is persisted, it seems to contain all the info I want to save (also information about the advanced filter dialog and row ordering), but it is just not properly loaded.

About number problem number 3: Is there any neat way for doing this automatically, or do I have to parse the filter object and "manually" insert the filter values into the text boxes and dropdowns? I am imagining this would be more difficult to do for the advanced filter dialog, where I actually need to create new "filter rows", and not just set a value in a text box

Will be thankful for all hints and help! I am not very skilled in jqgrid yet, but I am learning Smile
