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.

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...
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.
I m loading 5000 data in kendoui comobobox using transport property also setting ajax time 10secs .the loading exceeds the ajax timings sometimes it could not load the data in combobox.
can anyone help me
So I have a Kendo grid, that has two DropDownLists (DDL) in the toolbar.
The issue I am having is, the grid is dependent on the two DDLs, one which is loaded via an ajax call. However the grid does its ajax call before the DDL is populated, which leads to a failed call.
How can I force the grid to wait for the DDL to be populated.
Note: I CAN NOT give it a default value.
Thanks
Set autoBind to false. This will create the Grid but not load the data.
Then in the DropDownList dataBound event force the Grid to be loaded by invoking grid.dataSource.read.
I have a scenario where i need to use scrolled paging on my jqgrid, and it works perfectly. But now i need to add dynamic grouping capabilities to the grid as well. The problem I face, is that when I group the grid, only records in teh currently loaded page get grouped, and not the whole underlying dataset. Is there a way to acheive this using jqgrid.
a. Grouping groups all rows in a dataset, not just the ones loaded in a scrolled page in the grid.
b. When expanding such a group and scrolling, the grouped rows now follow scrolled paging
Any help here would be appreciated as I have been trying to figure this out for a while now with no luck :-(
Thanks
