    Hi,

    I am using kendo ui asp.net mvc.I have kendo grid with Virtualization support. Virtualization will load data on scroll. When grid has multiple pages at that time I can’t find records of previous page through JavaScript or Jquery and also I loss the state of previous record.

    Is kendo ui providing progressive data load support in grid control?

    In our application, we want to load data with progressive load like Silverlight.

    For ex:

    Case 1:

    I have 500 total records and grid page size is 20.So I will get 20 records in each page. When I scroll for more record previous record must maintain in same state. If I select any record through checkbox and move down and again come bake top previous record must get with select state.

     Case 2:

     I have 500 total records and grid page size is 20.So I will get 20 records in each page. My filtering, sorting and search will perform on server or backend service side. In first page I select top 5 records out of 20.now I search diff record which is not available in first 20 records so I have to take that from service but when I back must found previous record with new record in select state.

    How can I handle this type of situation without progressive load?

    Hello Sanjay,

    I am afraid that the selection of the checkboxes could not be kept when virtual scrolling is enabled and you scoll to get the next batch of records. This is because when virtual scrolling is enabled and you scroll down the tr elements which are no longer visible are removed from the DOM and next one are appended. 

    I am sorry for the inconvenience.

    Kind Regards,

    This seems like a solution I just found for this, to be able to track it.

    It has a live example too.
