extjs grid Select All checkbox issue

Question

I Want to get the total count of rows fetched when the user selects/checks SelectAll checkbox in Extjs grid.

Pls let me know how to do this.

Answer 1

To get all the rows in a grid, use:

store.getRange();

To only get the selected rows use:

var selectionModel = grid.getSelectionModel();
var selected = selectionModel.getSelection();

Answer 2

You can use like,

var sm = grid.getSelectionModel();
var Selected_record_count = sm.getCount()

Explanation;

getSelectionModel() - Returns the selection model being used and creates it via the configuration if it has not been created already.

getCount() - Returns the count of selected records.
