.data only runs once

[Phil]

@(Html.Kendo().Grid<MyModel>()
        .DataSource(ds => ds
            .Custom()
            .Batch(false)
            .Schema(schema => schema.Parse(@<text>parseData</text>))
            .Transport(r => r.Read(c => c.Action("GetStuff", "MyController",
                new
                {
                     prop = Model.prop
                })
                .Data("getExtraData()").Type(HttpVerbs.Post)))
            .PageSize(1)
            .ServerPaging(true)
        )

 

The getExtraData() method runs the first time the grid is loaded. I want to refresh the grid later, so I use this c

$('#messagesgrid').data('kendoGrid').dataSource.read();
$('#messagesgrid').data('kendoGrid').refresh();

 

The method getExtraData() has changed, so when it refreshes I want it to call this method again to attach the data to my request. However the method does not run even though the grid is refreshed.

 

How can I make sure that it runs every time the grid is updated?

I've fixed this by removing the brackets on the Data property.

 

.Data('someMethod') works

.Data('someMethod()') runs once then never runs again

Hi Phil,

Thank you for sharing with the community how you were able to resolve the error. Note that when you type a JavaScript method with brackets this will invoke the method immediately. Please examine the thread below that describes the behavior in more detail.

If you need additional information on sending data to the ActionMethods you would find the following article interesting.
