When endless scrolling and grouping is enabled on the KendoUI grid, collapsing large groups causes the grid to load ALL the hidden detail rows into the DOM.
This takes a very long time for the grid to do, as well it violates the whole point of a paging system. (ie I only want you to load X records at a time). Afterwards the performance of entire website (including the grid) will be very poor since potentially thousands of rows have been loaded into the grid and then immediately hidden. Additionally, these rows do not add any value to the user, since they are all hidden anyways.
When a category is collapsed, the grid should NOT add any new rows for that category to the DOM.
I have included a sample that demonstrates the performance issues.
the adaptive rendering in the grid control is not working in the current version(2019.3.1023).
To reproduce go to https://docs.telerik.com/kendo-ui/controls/data-management/grid/appearance/adaptive#configuring-panes-on-mobile --> Open in Dojo --> Run and the 2 rows are not displaying. If you switch to version, choose Library dropdown, 2018.3.1017 or up to 2019.1.220 the 2 rows are ok.
Similar behaviour is inspected to the scheduler control agenda view. To reproduce go to https://docs.telerik.com/kendo-ui/controls/scheduling/scheduler/adaptive-rendering#configuring-panes-on-mobile --> Open in Dojo --> Run --> change view from week to Agenda and the 2 events are not shown. If you switch to version, choose Library dropdown, 2018.3.1017 or up to 2019.1.220 the 2 events are ok.
Tried in chrome, safari and mobile phones.
The most important part of using Vue especially in Mobile, is it's small size and performance. Unfortunately, Kendo UI's Vue components are wrappers around jQuery which is something we are trying to avoid in our ongoing developments. I'd like to suggest building NEW Vue components in full native format with no despondency on other none related frameworks. Thanks! ..Ben
some time we need to looking up in folder On telerik ASP.NET is call FileManager We just need function like :http://elfinder.org/ Thanks
The ability to export a grid to excel has been a great addition, we would like the ability to export in CSV and XML also.
Currently, after export to excel and opening the exported file again in Spreadsheet, the row heights for rows with predefined height change. The above could be easily observed on the Index demo:
* initially, the height of the top row is set to 70px;
* export the Spreadsheet to Excel;
* after re-importing the above file, the height of the first row "Invoice #52" becomes 81px without any apparent reason.
