    Default Unanswered: Using ExtJs, a problem occurred when xml data received and paging

    Unanswered: Using ExtJs, a problem occurred when xml data received and paging


    Hi, all

    Using ExtJs, I m testing to transfer received xml data to specific grid.
    I made a simple text file which has 10 output values , and set pageSize to 5 from paging toolbar.


    That is, the desired output for 10 values could be 5 values on each pages(2 pages).
    It divided to 2 pages correctly, however there are 10 same values on each pages.


    What is the cause for above problem?
    I hope your comments will be possible solutions.

    Thank you!

    Please post in the correct forum. Your question appears to be about ExtJS 3, not ExtJS 4.

    Paging must be implemented server-side. Setting the pageSize will not chunk up the data into pages for you.

    There are 3 parameters on the request (page, start and limit) that you can use to determine which results to return. There is some overlap in these 3 parameters, just use whichever combination suits your use case.
