Hello,
I want to know that which event will be fired when I select the checkbox in the header of checkbox column. Is there any event which will be fired?

I tried your example but it gives me the value of page size as the value selected in the page size dropdown.
I need the count of the rows seen on current page. If the grid has only 2 rows on a particular page when page size is 10, it should return me 2 instead of 10.

Jash KapasiThanks for the response.
It is working now.
I tried all possible ways of referencing the script files.
I have used the same example from the demos. But I am still facing the same problem of dataadapter.
I removed two js file which were included in the code – jquery-1.10.2.min.js and jquery.js.
Instead of these two I only kept jquery-1.11.1.min.js.Now I am getting the following error :
‘Unable to get property ‘dataAdapter’ of undefined or null reference’.
I am getting this error at following line:
var dataAdapter = new $.jqx.dataAdapter(source, { loadComplete: function (data) { }, loadError: function (xhr, status, error) { } });Thank you for your response.
But where can I find ‘jquery.js’ file?
Following is the code which gives me the error in the dataAdapter initialization:
