How to Get All Selected Rows. Even when Filtered is applied.

[vijay@spinetechnologies]

I am using global search to filter data and then select rows using checkbox.
When i get the selectedRows using SelectRow().getSelection() it only gives me the selected rows from filtered records.
I want to get all selected rows without filter.
(i.e if I clear the search textbox and get selected rows then it gives all selected rows, but when the search textbox is not empty then it is giving selected rows from filtered records only).

I have also attached screenshots for reference.

Hi team,

If we use filterModel.hideRows = true, then select all Header checkbox is selecting all records. i want to select only filtered records.

That contradicts with your original requirement 

When i get the selectedRows using SelectRow().getSelection() it only gives me the selected rows from filtered records.
I want to get all selected rows without filter.

Please clarify.
