    I have put a subgrid on a form. This is shown or hidden according to a field value on the form.

    The onChange code I have on the field works fine, but the same code in the onLoad causes an error.

    Xrm.Page.getControl("mysubgrid") is null.

    How can I get access to the subgrid control in the onLoad?

    you can add a setTimeout in order to check for the subgrid

    function GridEvent(gridName) {
   // retrieve the subgrid
   var grid = Xrm.Page.getControl(gridName);
   // if the subgrid still not available we try again after 1 second
   if (grid == null) {
       setTimeout(function () {GridEvent(gridName);}, 1000);
       return;
   } else {
     // your code here
   }
}

    The proper way would be:-

    As all grids are child entities therefore you should use oData (retreivemultiple) and check child entity count and show hide the grid based on count.
