[CLOSED] Filtering in Store Load event doesn't work in complex pages
Hello,
I've found out, that sometimes filtering a grid in a store's load event doesn't work, if the page is too complex. Maybe the filter method is called before the grid is rendered? The solution for me is to add Delay.
This is a working simple solution without Delay:
Thanks!

new Company { Name = "Heaven" },

companies.Add(new Company { Name = "Hell 666"});

this.Store1.DataSource = companies;
this.Store1.DataBind();
