Xrm.Page.getControl() returns null

Using CRM 2015.

I'm creating a button that loops over the selected records in a view and performs a custom method.

Here's the setup:

Created a button on the main view menu bar in one of our custom entities.

Added javascript for the new button to call.

try {
var selectedEntityReferences = [];

var selectedRows = Xrm.Page.getControl("<control name here>").getGrid().getSelectedRows();
alert("selectedRows:" + selectedRows.getLength());

selectedRows.forEach(function (selectedRow, i) {

selectedEntityReferences.push(selectedRow.getData().getEntity().getEntityReference());
alert(selectedRow.getData().getEntity().id);

});
} catch (ee) {
alert(ee.message);
}

I tried replacing "<control name here>" with what I thought the name of the control was - but it gives 'selectedRows is null' error.

This sent me on a search to find the proper control name.

In the MSD documentation I found 'Xrm.Page.getControl()' should return a list of controls - but when I use this method it returns a null object.

This leads me to believe there are no controls on the page - but how is this possible?

Also - where would I find the proper name for the control that holds the view grid?

RE: Xrm.Page.getControl() returns null

Bit old but running Xrm.Page.getControl() in DevTools returned everything on the page and i went through there and found my field named "header_new_fieldname" and what I am assuming happened is when I first created the form I put it on the header and now its in the form but it kept the header tag some how.

Updating my code to call the header worked. Or i could remove and re-add it or maybe even in classic there would be something to update its name.

I found the answer to this.

In this case - I am not looking at a sub-grid. When looking at a view - you just need to pass the MSD Parameter 'SelectedControlSelectedItemIds' to your function. This will give the GUID of the selected items in the view.

Hi CRM Novice,

to get the right control name you need to enter form editor the double click on grid control and get name value.

Please let me know if you solve.
