Build 2013.1.319 Introduces js issue

After just downloading and upgrading to build 2013.1.319 - I now receive the following error when starting my app:

Microsoft JScript runtime error: Object doesn't support property or method 'live'

The error occurs in jQuery.unobtrusive-ajax.js (Asp.net mvc):

$("a[data-ajax=true]").live("click", function (evt) {
        evt.preventDefault();
        asyncRequest(this, {
            url: this.href,
            type: "GET",
            data: []
        });
    });

p.s. I am using the jquery.min.js that comes with the latest Kendo build.

Please advise.

[Solved] Exception with Grid After Updating to Latest Build (2013.2.716.340)

I've noticed now the grid is posting filter data even though I haven't defined any filter on the client/server side. This is causing a Binding error - DataSourceRequest.

When I create a dummy filter with the wrapper it no longer throw exception. However even if I disable the Filterable option it still throws and passing filter post data.

.DataSource(ds => ds.Ajax()

.Batch(true)

.Filter(f=> f.Add(d=> true))

See the examples of post data between working and not. I'm not sure if it's the wrappers or the JS but thinking it might be Js causing the Binding to throw.

Old Post Format:
sort=FacilityName-asc&page=1&pageSize=25&group=&filter=

New Post Format Failing:
sort=FacilityName-asc&page=1&pageSize=25&group=&filter=undefined~undefined~undefined

New Post Format Working - see above for the dummy filter:
sort=FacilityName-asc&page=1&pageSize=25&group=&filter=undefined~eq~null

Please advise.

Grid Editing with ASP.NET MVC and LinqtoSql Entity Framework

Sorry if this has been covered somewhere, but I'm new to Kendo and am having trouble finding examples and/or documentation on this.

Basically I'm trying to figure out how to leverage a LinqtoSql entity framework in a .NET MVC application to handle edits/updates/deletes to my database with a Kendo Grid. I'm coming from an AJAX .NET webforms (so not even MVC!) world where tying a .NET grid to a LinqDataSource was pretty much all you needed to handle CRUD operations.

Thanks!

Hi,
I am trying to render a different partial view based on a property of the model. I will then need to pass the model from the current enumeration to the Html.RenderPartial called in the template

@using Assessments.Models;

@model IEnumerable<FallsAssessment>

@{

ViewBag.Title = "FallsAssessmentList";

}

<h2>FallsAssessmentList</h2>

@Html.Kendo().Grid(Model).Name("FallsAssessments").Columns(columns=>

{

columns.Bound(m => m.AssessmentType).Title("Assessment Type");

columns.Bound(m=> m.Ward).Title("Ward");

columns.Bound(m=>m.LastUpdated_TS).Title("Last Updated");

Error rendering data with autocomplete - Object #<Object> has no method 'slice' - how to resolve?

I am following the Using Kendo UI with MVC4 WebAPI OData and EF article. After installing KendoUI and making sure all references are set, I type in three characters, and get the following error:

Uncaught TypeError: Object #<Object> has no method 'slice'

I cleaned up kendo.web.min.js and the error is occuring around line 3498:

success: function (n) {

var i = this,

r = i.options;

return i.trigger(wt, {

response: n,

type: "read"

}), n = i.reader.parse(n), i._handleCustomErrors(n) ? (i._dequeueRequest(), t) : (i._pristine = et(n) ? e.extend(!0, {}, n) : n.slice ? n.slice(0) : n, i._total = i.reader.total(n), i._aggregate && r.serverAggregates && (i._aggregateResult = i.reader.aggregates(n)), n = i._readData(n), i._pristineData = n.slice(0), i._data = i._observe(n), i._addRange(i._data), i._process(i._data), i._dequeueRequest(), t)

The Kendo UI widgets are loading just fine as well as the css:

<link href="~/Content/kendo/kendo.common.min.css" rel="stylesheet" />

<link href="~/Content/kendo/kendo.default.min.css" rel="stylesheet" />

<script src="~/Scripts/jquery-1.9.1.min.js"></script>

<script src="~/Scripts/kendo/kendo.web.min.js"></script>

<script src="~/Scripts/kendo/kendo.aspnetmvc.min.js"></script>

<script src="~/Scripts/appScripts.js"></script>

And I am seeing the same error both with using the Razor MVC helper/extension:

@(Html.Kendo().AutoComplete()

.Name("userAutoComplete") // specifies the "id" attribute of the widget

.DataTextField("USERNAME")

.DataSource(source =>

{

source.Read(read =>

{

read.Url("/api/user");

})

.ServerFiltering(true); // if true, the DataSource will not filter the data on the client

}

)

and through directly through JS:

/// <reference path="kendo/kendo.aspnetmvc.min.js" />

/// <reference path="kendo/kendo.core.min.js" />

/// <reference path="kendo/kendo.autocomplete.min.js" />

/// <reference path="kendo/kendo.web.min.js" />

$(document).ready(function () {

// load up KendoUI

// gets data from /api/user

var dataSource = new kendo.data.DataSource({

transport: {

read: {

url: "/api/user"

}

});

$("#userSearch").kendoAutoComplete({

dataSource: dataSource,

dataTextField: "USERNAME",

minLength: 3

});

$("#userSearch").on('input', function () {

console.log($("#userSearch").val());

});

}); // $(document).ready()

I'm sure this is something simple that I may be missing. I have tried both with the web and all js files.

Any assistance would be appreciated.

Thanks.

Grid ToolBar custom item/template

I am having difficulty working out how to add a Date picker to the Grid ToolBar in order that I use it to filter a large data set (500,000+ reords).

The documentation for showing how to do this for Kendo UI doesn't translate easily to MVC warpper versions.

[Solved] IE8 Bug: Grid-Cell does not stay in edit mode after new row has been added

Hello,

the following bug only occurs in IE 8 and is only reproduceable with IE 8. It is not reproduceable, if you switch your browser to IE 8 mode (via IE Toolbar). So please use a "real" IE 8 browser to reproduce:

OK, here is the bug:
If you add the first row to an empty grid (grid is in batch mode) it is working fine. After you inserted the new row, the grids renders the first cell in edit mode. Now if you add another row, the cell automatically switches from edit-mode to display mode. This occurs for every new grid row > 1.

It also seems, that the bug is connected when using custom Editor Templates (UIHint property set to reference to a custom editor grid cell template). For example I created a simple EditorTemplates that renders the Kendo Auto-Complete Textbox when the grid cell is in edit mode.

Do you have any ideas what can cause the bug in IE 8, or do you need a sample application to reproduce the bug?
