RadGridView: HeaderCheckbox check/uncheck checkboxes of the first page only when EnablePaging = true
Now, I have 2 problems:
1. Checking / Unchecking header check box, checks/unchecks checkboxes of current page only. I need to perform the operation for the whole grid.
2. I have got filters on. User can select filters on columns. Once filters are applied, records are displayed according to those filters (other records are hidden). Now, when checking the header check box, it only selects records that are part of current page. For example, if I am on first page and apply filter on one column, grid will hide all rows from the first page that do not match the filter and pull records from 2nd and 3rd pages that match the criteria and show on the first page. But if I select check box in the header, then only records from first page are selected, records that came from 2nd and 3rd page are not selected.
