OnDataBinding

Telerik.Web.UI.OnDataBinding Property

To get or set property values for client API properties, you must call property accessor methods that are named with the get_ and set_ prefixes. For example, to get or set a value for a property such as cancel, you call the get_cancel or set_cancel.

This event will be raised when the grid is about to be bound to data client-side. Can be used to change dynamically any of the grid declarative client-side binding properties if needed.

Meaningful with client-side data-binding only!

This event will be raised twice by default - the first call will retrieve the data and the second call will fetch the total items count.

Fired by	RadGrid
Arguments	location - the physical location of the web service/page method which retrieves the data for the grid methodName - the name of the method which collects the data methodArguments - the arguments that will be passed to the method which gets the data (start row index, maximum rows, sort parameter, filter parameter)
Can be canceled	Yes, set eventArgs.set_cancel(true) to cancel
