How to hide rows in ExtJS GridPanel?

Question

Suppose I know which row index to target (with this.rowToBeDeleted having a value of 2, say), how can I hide this row only from the grid but not the store (I have a flag in the store, which signifies what rows should be deleted from the db later in my PHP webservice code).

Answer 1

I suggest using store.FilterBy() and pass a function to test the value of the value in rowToBedeleted:

store.filterBy(function(record) {
    return record.get("rowToBeDeleted") != 2;
});
