jQuery Grid Plugin - jqGrid

Hi,

I m using JqGrid. I have created an application where I used to copy grid elements from one page to other. The Other Page have Tabs Structure, Whenever I click on One tab call "Budget Codes", it clears one column of first row. I really don't understand the problem. Please help me in this.

Below is the snapshot for same:
[Image Can Not Be Found]

And here is my code:

function LoadBudggrd(Bindjson) {
    var LoadGrd = (CurGrd == 4);
    if (LoadGrd || BudGrdNotLoaded) {
        budggrd.setGridWidth(1500, true);
        budggrd.setGridHeight("100%", false);
        if (LoadGrd) {
            ShwHidGrds(true);
            budggrd.setGridParam({ datatype: "jsonoffline", offlineData: Bindjson, width: 1140, viewrecords: true, pager: $j('#pagerMtrl')
        }).trigger("reloadGrid");
        }
    }
}

Here Data Comes properly in Bindjson but it is not showing inUI side. Please help me.

Thanks in Advance,
