Update Grid Fetch in client side

Here is my example to update grid request in Client Site.

create new function and check if grid is already loaded

function UpdateGridOptions() {

    var myGrid = document.getElementById("myGridExample");

   
    if (myGrid == null || myGrid .readyState != "complete") {
     
        setTimeout('UpdateGridOptions()', 1000);
        return;
    }
    if (Xrm.Page.getAttribute('accountid').getValue() != null) {
        var accountId = Xrm.Page.getAttribute('accountid').getValue()[0].id;
        var fetchXml = GetFetchForGrid(accountId, Xrm.Page.data.entity.getId());
        //update grid with new fetchXml
        myGrid .control.SetParameter("fetchXml", fetchXml);
        //Refresh grid
        myGrid .control.refresh();

    }
}

Enjoy,
