I have a ScrollViewer where I need to change the pages on the fly. As you navigate the app I'm changing the content of a scrollviewer in a different view (pre-loading content). If I go from 3 pages, down to 1, and back up to 3 the ScrollViewer only shows 1 page. I've tried the refresh() and content() methods but that doesn't seem to re-initialize the scrollviewer. If I change the content of a scrollviewer how do I tell it to re-initialize itself?

[Solved] Handling server side errors (non-MVC version)

I'm aware of the following example showing how to deal with server side errors.
http://www.kendoui.com/code-library/mvc/grid/handling-server-side-validation-errors-during-pop-up-editing.aspx

However I'm trying to handle server side errors using the non-MVC version of the Kendo grid and I notice in the API there is no dataBinding event that I can cancel. So how would I cancel the data binding in this scenario? Thanks,

Scott

Show progress on Grid popup edit save

I have a Grid which uses popup editing with a custom popup template.

I've finally got it all working just as I want, with some tricky ajax driven validation, but I've now run into a slight problem.

It takes a couple of seconds for the new or updated data to be sent to the server and a valid response to be received. In this time, users are thinking they've not clicked the Save button properly and are resubmitting the data.

What would be the best way to show some sort of progress indicator to let the user know something is happening until the popup closes and the grid is displayed again.

Thanks.

Hidden validators when virtual scrolling & createAt bottom

Hello,

I have a grid with virtual scrolling on it due to huge data.
On all my grids I would like to create new lines only at the bottom of the grid.
When the grid has to display a validator ("field required" as for exemple) the validator is hidden at the bottom of the grid (we only see the arrow but not the complete message).
I don't think it will be hard to reproduce, is there a workaround ? Thanks

.kendoMobileListView Web API and endlessScroll challenges

I am having issues getting endlessScroll to work to work with API. Maybe I am just not putting two and two together. I have seen options of converting IEnumerable to IQueryable OData, but that did not work either. Watching the Network trace, it appears that it is passing the correct parameters to the Web API controller.

The current issue is that when I scroll down, the endlessScroll does not get triggered for more records. It returns the pageSize specified but does not make another request to the Web API Get(). Please help! And thanks in advance for the assistance.

HERE IS MY INDEX.HTML PAGE SCRIPT. BELOW IS MY WEB API GET()

<script>

var dataSource;

function listViewInit(e) {

dataSource = new kendo.data.DataSource({

pageSize: 10,

page: 1,

serverPaging: true,

transport: {

read: {

url: "/api/Message/?isArchive=false",

dataType: "json",

type: 'GET'

}

},

parameterMap: function (options) {

var parameters = {

take: options.take,

skip: options.skip,

pageSize: options.pageSize,

page: options.page //next page

};

return parameters;

},

schema: {

data: function (data) {

return data.Data;

},

total: function (data) {

return data.Count;

}

});

e.view.element.find("#secure-inbox").kendoMobileListView({

endlessScroll: true,

dataSource: dataSource,

template: $("#listTemplate").text(),

scrollThreshold: 10

})

.kendoTouch({

filter: ">li",

enableSwipe: true,

touchstart: touchstart_inbox,

tap: navigate_inbox,

swipe: swipe_inbox

});

}

// Other Functions Removed For Forum Post //

</script

>






// GET api/<controller>
       public object Get(bool isArchived = false, int page = 1, int pageSize = 20)
       {
           IEnumerable<Message> data;
 
           int count;
 
           triagedbEntities db = new triagedbEntities();
           db.Configuration.ProxyCreationEnabled = false;
 
           data = (from x in db.view_secure_messages
                       where (x.TriageDecision != null) == isArchived
                       select new Message
                       {
                           msg_id = x.MessageID,
                           message_subject = x.MessageSubject,
                           message_received = x.MessageReceived
                       }).OrderByDescending(a => a.message_received).Skip((page - 1)*pageSize).Take(pageSize).ToList();
           count = data.Count();
 
           return new
           {
               Count = count,
               Data = data
           };
       }

[Solved] Error occurs when invoking addRow on a Grid with templated column

Hello Kendo,

With your latest 2013Q1 release, we just encountered an error every time when trying to add a new row on ui.Grid, which a templated column was involved. A simple code sample shows as below:

<script>
$(function() {
$('#grid').kendoGrid({
dataSource: {
data: [
{ a: "dafdsf" }
]
},
columns: [
{
field: "a",
width: 120,
template: 'template: #= a #'
}
]
});

$('#add').click(function() {
$('#grid').data('kendoGrid').addRow();
});
});
</script>
</head>
<body>
<div id="grid"></div>
<button id="add">add</button>
</body>

When the add button was clicked, an error "Uncaught ReferenceError: a is not defined " went out.

Can you please take a look at this, as this is so much urgent for us. Or could you suggest any other work around?

Thanks,
Wenhao

Area Chart

How do you make an area chart whose first x-axis data point is not aligned with the y-axis start the "area" from the y-axis (origin)?

In my specific example, January is our first x-axis data point, and since the January data point is not aligned with the y-axis, there is a space of "emptiness" that looks funny on the chart. I would like the area chart to begin at the intersection of the x-axis and y-axis so that gap is filled (the January data point does not need to move, the area chart just needs to start at the origin and move to the first data point, which will be January). The reason the area chart does not begin at the y-axis is because the exhibit includes both an area chart and line chart.

I've added a photo to help describe the problem.

Thanks in advance for the help.
