Answer 1

Based on your code I can suggest to recheck id of a section. Is it really ChildCasesGrid? Could you please provide a screenshot of section settings form?

Based on provided screenshot you use id of a grid and not of a section on which it is put. So solution - find Id of a section and put it to your code.

Answer 2

Since the only .controls you're attempting follows this line

Xrm.Page.ui.tabs.get("general").sections.get("ChildCasesGrid")

then it means that .get("ChildCasesGrid") result is null or undefined.

This means that you don't have any section named ChildCasesGrid inside the tab named general : either one of the names is wrong (watch out, they are case-sensitive).

Answer 3

@andrii butenko that's the name of my section

Answer 4

你真的想做Xrm.Page.getControl("ChildCasesGrid").setLabel("new label")来设置子网格的标签
