Identify the trigger for an On-load event for Sub-grid in Dynamics CRM | MS CRM
Introduction :
With CRM 2015 SP1, the client API was extended to allow attaching events to subgrid to manage the subgrid data operations.
The OnLoad event however executes on all of the following operations
1.Load of parent form
2.Save of parent form
3. Add a new record in sub grid
4. Remove a record from sub grid
5.Navigating to prev/next page in sub grid
when we register a method on the onload event, ts does not indicate in any way which of the above actually fired the onload event
Workaround to identifying the operation :
We cannot register an event when the record is added/removed from the sub grid. The only event available is onload so one way to identify if it was one of the add/remove operations that caused the grid to call the onload event. we can keep a check on the count of records in the grid.
we can register the onload event using the following code
function onLoad() {

The rowcount is defined as global variable and is updated here to store the count of records in the grid when the form is loaded initially.
function
onGridLoad() {
var functionName = " onGridLoad ";
var currentRowCount = null;
try {
//setting timeout beacuse subgrid take some time to load after
the form is loaded
setTimeout(function () {
//validating to check if the sub grid is present on the form
if (Xrm.Page != null && Xrm.Page != undefined
&& Xrm.Page.getControl("contact_subgrid") != null
&& Xrm.Page.getControl("contact_subgrid") != undefined) {
//stores the row count of subgrid on load event of CRM Form
currentRowCount =
Xrm.Page.getControl("contact_subgrid").getGrid().getTotalRecordCount();
if (currentRowCount >
_rowCount) {
//call the intended function which we want to call only when records
are added to the grid
dosomething();
//set current row count to the global row count
_rowCount = currentRowCount;
}
else if (currentRowCount < _rowCount) {
//call the intended function which we want to call only when
records are removed from the grid
dosomethingelse();
//set current row count to the global row count
_rowCount = currentRowCount;
}
}
}, 2000);
} catch (e) {
Xrm.Utility.alertDialog(functionName + "Error: " +
(e.message || e.description));
}
}
