如何获取扩展的jqGrid行列数据

Question

When Main jqGrid row is expanded a subgrid is constructed and displayed. I need to capture main grid expanded row column data before subgrid is constructed. For that i'm using subGridBeforeExpand event of Main Grid. In that event the i'm calling a javascript code to capture expanded row column data but with out any success . alert throws sel_id as null . Could any one guide me on this?. Do i need to use another grid event or something wrong with my jquery code?.

**<script type="text/javascript">
     function GetValues() {
       var sel_id = jQuery("#ServersWS").jqGrid('getGridParam', 'selrow'); 
       alert(sel_id);
       var rowData = jQuery("#ServersWS").jqGrid('getRowData', sel_id);
       var temp = rowData['Description']; //replace name with you column
       alert(temp);
    }
</script>**     

 div id="gridWrapper1" style="display: none">
    @{

        var grid1 = new JqGridHelper<Configuration.Models.Post.ProfileModel>(
            "ServersWS",

I am not familiar with Lib.Web.Mvc library, but you can try to use jQuery events instead of callbacks . For example jqGridSubGridBeforeExpand could be what you need:

jQuery("#ServersWS").bind("jqGridSubGridBeforeExpand", function (e, pID, rowid) {
    alert("rowid=" + rowid);
});
