OK if someone have the same situation like me here is the solution:

- I made function for grid initialization:

function constructGrid(){
       $("#mygrid").jqGrid('GridUnload');
       jQuery("#mygrid").jqGrid({
           datatype: "local",
           height: 200,
           colNames:['One', 'Two', 'Three', 'Four','Five'],
           colModel:[
               {name:'col1',index:'col1', width:100},
               {name:'col2',index:'col2', width:100},
               {name:'col3',index:'col3', width:100},
               {name:'col4',index:'col4', width:100},
               {name:'col5',index:'col5', width:100}
           ],
           viewrecords: true,
           caption: "Some Caption"
       });
   }

- on document.ready – call :

constructGrid();

- on callback function which returns new data:

success: function(data){
               constructGrid();
               for(var i = 0; i <= data.length; i++)
                   jQuery("#mygrid").jqGrid('addRowData', i+1, data[i]);
           }

And that works for me.

grid.custom.js is loaded after jquery.jqGrid.min.js (I've try before and after and still the same )

It was my mistake by using GridUnload. This is the correct way:

jQuery("#maygrid").jqGrid('GridUnload');

But no matter that now the result in firebug is:

u.p is undefined

I just try something like this:

GridUnload(jQuery("#maygrid"));

for(var i = 0; i <= data.length; i++)
jQuery("#maygrid").jqGrid('addRowData', i+1, data[i]);

And the grid was empty, but not pre filled.

Hello guys. I am using jqgrid to create dinamic tables with datatype: "local". But i saw something strange: instead of replacing rows the grid is appending new results. So i was wondering is there a way to flush table content before add new data?

Thanks in advance!
