I am working with an application where I have thousands of images to load on ImageBrowser of Kendo Editor.
ImageBrowser is getting stuck as having too many images to load, Can we have any option to add pagination or lazy loading in ImageBrowser?
So, I can load only 20 images at a time and other based on request.
Please note that I am fetching images from controller method which returns list of FileBrowserEntry as below.
Thanks in advance...
I'm using primefaces (5) autocomplete component where the total number of options is around 500. While this is a high number, the data sent is quite simple and the transfer from server to client is quick.
I was wondering if it is possible to preload/cache all autocomplete options on page load in order to avoid any ajax delay while the user is writing text.
Does anyone know of how to do this?
Can any one please let me know how can I load first 5000 rows into kendo grid and then load the remaining rows on page selects. I have 50000 rows to load and the page with kendo grid is loading pretty slow. So I want to use lazy loading approach..like loadin gthe first 5000 and then load the next rows in 1000's on page button clicks.
Any help appreciated!
You can either enable virtual scrolling or implement server paging.
Set server paging true for Kendo Data source
Set Page Size 300 for Kendo Datasource
Set Virtual scroll true for kendo grid
Now make sure in grid has 6000+ records
Scroll down grid to middle (such that you want to see 300 record on 50th page)
If you observe in browser, kendo grid data source call to get records for each page still the 50th page arrived.
Yes it will call for every page if you don't move the scroller fast.
Kendo says following about virtualization : If set to true the grid will always display a single page of data. Scrolling would just change the data which is currently displayed.
There is an existing issue with multiple requests during fast scroll.
If you want to limit performance hit and you don't want to always load 300:
make page size smaller - in this case the virtualization is quite likely going to skip some pages. However this relies at the users skill to scroll fast, if they scroll slow all the pages will be loaded.
implement server side paging via pager and avoid virtualization- this will allow you to control what are you getting from the server.
When using the "virtual scroll" feature of jqgrid to only create elements that are displayed for large data sets there is a lag while it builds up the cells.
If you are using ajax to fetch data the loading display appears but if the datatype is local the display doesn't get a chance to update with the loading message and user sees a blank table for a while until it renders.
Are there any suggestions for how to get the loading message to show for this scenario? Are there any events or hooks into jqgrid for adding a timeout to get the browser a chance to render the loading message?
