How to set the dataSource.transport.read at run time and not execute dataSource.transport.read on request but not on page load?

[AsA]

Problem:

 

A kendo UI "window" widget that contains a "grid" widget.

 

The "window" is a popup window, it is hidden on initial page load.

 

The "window" and the "grid" are initialized using Markup ( data-role="window", data-role="grid" and bind, no JavaScript configuration, only for events)

 

A button "Open Window" opens the popup window that has inside a grid.

 

Every time the popup window is opened a new Ajax call must be done for reloading the grid (through: $("#grid").data("kendoGrid").dataSource.read();)

 

Questions:

 

1. How can be avoided to load data the first time?
Note - I do not bind the grid but as the grid nested into the window (container), when that (the window) is bound, the grid is then bound as well
(is there a way to avoid this behaviour?
It could be done defining the grid outside the window and "attach" it at runtime but I would keep the HTML consistent).

 

2. Is there a way to not raise the dataBound.transport.read the first time (on page loading / binding)?

 

3. I tried to set an empty url (for avoiding the Ajax call on page loading) and then change it at every open popup ($("#grid").data("kendoGrid").dataSource.options.transport.read.url = url;) but it doesn't work, the url doesn't change.

 

Thank you for help

Hello AsA,

 

 

Straight to your questions:

 

1. You can set autoBind to false, so no data is fetched until dataSource.read() method is used. It is explained here:

 

http://docs.telerik.com/kendo-ui/api/javascript/ui/grid#configuration-autoBind

 

2. Same as above

 

3. You can use setOptions to change any of the Grid defined options, here is the relevant documentation piece:
