Hi try following its working for Rollup 12 and earlier.
function UpdateSubGrid() {
//This will get the related entity grid details and store in a variable.
var relatedGrid = document.getElementById("SubGrid");
//Get the lookup field
var lookupfield = Xrm.Page.getAttribute("new_relatedEntityid").getValue();
//This will get the lookup field guid if there is value present in the lookup
if (lookupfield != null) {
var lookupid = lookupfield[0].id;
var lookupName = lookupfield[0].name;
}
else {
return;
}
//This method is to ensure that grid is loaded before processing.
if (relatedGrid == null || relatedGrid.readyState != "complete") {
setTimeout('UpdateSubGrid()', 2000);
return;
}
//This is the fetch xml code which will retrieve all
//the related entity records to the lookup selected
var fetchXml = "<?xml version='1.0'?>";
fetchXml += "<fetch version='1.0' output-format='xml-platform' mapping='logical' distinct='false'>";
fetchXml += "<entity name='new_entity'>";
fetchXml += "<attribute name='new_name' />";
fetchXml += "<attribute name='new_code' />";
fetchXml += "<attribute name='createdon' />";
fetchXml += "<order attribute='new_name' descending='false' />";
fetchXml += "<filter type='and'>";
fetchXml += "<condition attribute='new_relatedEntityid' operator='eq' uiname='" + lookupName + "' uitype='new_relatedEntity' value='" + lookupid + "' />";
fetchXml += "</filter>";
fetchXml += "</entity>";
fetchXml += "</fetch>";
try{
//Setting the fetch xml to the sub grid.
relatedGrid.control.setParameter("fetchXml", fetchXml);
//This statement will refresh the sub grid after making all modifications.
relatedGrid.control.refresh();
}
catch(e) // FOR ROLLUP 12
{
//Setting the fetch xml to the sub grid.
relatedGrid.control.SetParameter("fetchXml", fetchXml);
//This statement will refresh the sub grid after making all modifications.
relatedGrid.control.Refresh();
}
