jQuery Grid Plugin - jqGrid

Hi!,

1. I have set the multiselect =false and yet I can multiselect the rows..

I destroy and create the grid depending on what was button was clicked as I need to display different columns and create differnt toolbar in the grid.

In one of the button the multiselect :false work but on the other two it does not..

2. My second problem is when the page loads it shows the Warning popup with Please select row.. It also disables the whole grid. once I close the popup it is ok, but wehn I destroy it and recreate it, the popup does not show but grid is disabled.. I commented out a in grid.base.js around line no779  $("<div class='ui-widget-overlay jqgrid-overlay' id='lui_" + this.id + "'></div>").append(ii).insertBefore(gv);

With this commented I do not get the disabling but the warning still shows up.

Any pointers will be greatly appreciated..

Thanks

My code is as follows:

function setupGrid(cols, colNames, sortnm, NodeId, Type, title) {
    jQuery("#NodeTable").jqGrid({
       datatype: function(pdata) {
            // alert(JSON.stringify(pdata));
            jQuery.ajax({ type: "POST",
                url: "../asmx/MainPg.asmx/GetNodeTableNew1",
                dataType: "json",
                data: JSON.stringify(pdata),
                contentType: "application/json;charset=utf-8",
                processData: false,
                error: function(XMLHttpRequest, textStatus, errorThrown)
                { ajaxError(XMLHttpRequest, textStatus, errorThrown); },
                success: function(result) {
                    grdData = JSON.parse(result.d);
                    var thegrid = jQuery("#NodeTable")[0];
                    thegrid.addJSONData(grdData);

                }
            })
        },
        colNames: colNames,
        colModel: cols,
        pager: jQuery('#pager2'),
        rownumbers: true,
        rowNum: 10,
        rowList: [10, 25, 50],
        sortname: sortnm,
        viewrecords: true,
        sortorder: "asc",
        caption: title,
        multiselect: false,
        autowidth: true,
        height: "auto",
        toolbar: [true, "top"]
    });
    jQuery("#NodeTable").navGrid('#pager2', { add: false, edit: false, del: false, search: false, refresh: true });
    CreateToolBar(NodeId, Type);

}
