jQuery Grid Plugin - jqGrid

Hi,

 

I have some cases where I have a lot of columns, so naturally - I use column chooser - but I also want that the DB backend to select the appropriate columns.

For that, I need to know each time column chooser submit - and the columns chosen.

I managed to do that...

jQuery("#scroll37").jqGrid ('navButtonAdd','#pscroll37',{
  caption: "", buttonicon: "ui-icon-calculator", title: "choose columns",
  onClickButton: function() {
    jQuery("#scroll37").jqGrid('columnChooser', {
      done: function(perm) {
         if (perm) {
             alert("The column chooser closed with 'OK' button");
             var cols = [];
             $.each(
             $('#scroll37').jqGrid('getGridParam', 'colModel'),
             function () {
             if (!this.hidden && !this.hidedlg) {
                 cols.push(this.index);
                 alert(this.index);
                 alert(this.name);
                 //problem here: $("#scroll37").trigger("reloadGrid");
             }
         }
     );
  } else {

   alert("The column chooser closed with 'Cancel' button");

    }
}});
}});

The problem is where it says "//problem here" in the code: After I know which columns were selected, I want to respond to the event. If I refresh the grid, it resets itself completley (even if I were at the bottom of the grid, it will load it all again)... So I'm looking for a way to trigger the call to the url - and of course I want to be able to pass parameters (to pass the columns).

 

So something like this:

$("#grid").jqgrid('callUrl','myUrl?columns=a,b,c');

But haven't been able to find such API.

Thank you.
