I'm using a Kendo UI Grid in conjunction with two AutoComplete widgets. Everything mostly works perfectly, however, if a user pages through the grid and then does a search using one of the AutoComplete widgets, the grid does not display the data. The pager at the bottom of the grid is updated but the grid is blank. The user must click on a page before the data is displayed. I have not been able to find a setting to resolve this despite hours of Googling. Here's the code for my grid:

@(Html.Kendo().Grid(Model)

.Name("grid")

.Columns(columns =>

{

columns.Bound(a => a.EmployeeOI).Visible(false);

columns.Bound(a => a.DepartmentOI).Visible(false);

columns.Bound(a => a.LevelId).Width(60).Title("Level");

columns.Bound(a => a.DepartmentName).Width(150).Title("Department");

columns.Bound(a => a.EmployeeId).Width(60).Title("Emp");

columns.Bound(a => a.BuyerName).Width(100).Title("Buyer Name");

columns.Bound(a => a.MinAmount).Width(100).Title("Min Amt");

columns.Bound(a => a.MaxAmount).Width(100).Title("Max Amt");

columns.Command(command => { command.Edit(); command.Destroy(); }).Width(200);

})

.ToolBar(toolbar => toolbar.Create())

.Editable(editable => editable.Mode(GridEditMode.PopUp))

.Pageable()

.Sortable(s => s

.AllowUnsort(false)

.SortMode(GridSortMode.MultipleColumn))

.Scrollable()

.HtmlAttributes(new { style = "height:650px;, width:100%" })

.DataSource(dataSource => dataSource

.Ajax()

.Sort(x => x.Add(y => y.LevelId).Ascending())

.Sort(x => x.Add(y => y.MaxAmount).Ascending())

.ServerOperation(false)

.PageSize(8)

.Events(events => events.Error("error_handler"))

.Read(read => read.Action("Read", "Home").Data("gridAddlData"))

.Create(update => update.Action("EditingPopup_Create", "Home"))

.Update(update => update.Action("EditingPopup_Update", "Home"))

.Destroy(update => update.Action("EditingPopup_Destroy", "Home"))

.Model(m =>

{

m.Id(i => i.Id);

m.Id(i => i.EmployeeOI);

m.Id(i => i.DepartmentOI);

m.Field("LevelID", typeof(string));

m.Field("EmployeeId", typeof(string));

m.Field("BuyerName", typeof(string));

m.Field("MinAmount", typeof(decimal));

m.Field("MaxAmount", typeof(decimal));

m.Field("DepartmentId", typeof(string));

})

)

Will UI for MVC work in the same project as UI for AJAX controls

We have a rather large project that uses the Telerik UI for ASP.NET AJAX tools. We are looking to do our new work in this project using the UI for MVC controls. Are there any issues mixing these two Telerik toolsets in a single project? We cannot seem to find any information on this online.

UI for MVC Grid error

I'm working through the Grid HtmlHelper extension example in the Telerik documentation. I get red squiggly line with 2 errors.Unknown method and unknown type. When i debug I get " CS0246: The type or namespace name 'KendoGridServerBinding' could not be found (are you missing a using directive or an assembly reference?)" I have the add namespace in web.config and the kendo.mvc is referenced in my project. I have attached the code and error.

Testing Lazy Loading

I've downloaded and I'm running the kendoui-northwind-dashboard-master project.

In the OrdersController I've set a breakpoint on the Orders_Read Action.

I run the application in Debug and navigate to the Products & Orders page.

In Locals I drill down into orders/Results View and it returns 830 records.

I then set the Order Date filter to 'Is after 4/22/1998'.

In Locals I again drill down into orders/Results View and it still returns 830 records.

The view properly filters and returns 34 items.

1. Is Lazy Loading being used in this Grid?

2. If so how do I verify only the filtered records are returned from the DB query?

3. If Lazy loading is not being used in this project could you point me to or supply me with one that is?

I need to be able to build a project that scales properly so that I can return a subset of records rather than the thousands of records that will be in the database.

Issue with grouped multi select list when selecting an item

I've found a strange behaviour thats happening when i've got a grouped multi select list (again virtualised as asked in the other thread "Multi select change event not firing") and try to select an item.

The grouping function itself seems fine, as i can see the different items are under their respective headers, however when i try to select an item from the drop down list, a completely different item is selected instead of the selected item (most of the time it seems to be reversed, e.g. items 1, 2, 3, 4 showing on grouped list. Select item 1, and item 2 gets selected. Select item 2, item 1 gets selected. Sometimes the correct item is selected).

If there is no grouping applied, the selected value is always correct.

Kendo UI Grid Ajax Binding with DetailsTemplate

I try to make a grid hierarchy. I have two grids. One of them is inside of the other. Parent grid reads the data via ajax read method. Returning json result has a field of a list. I want to use this list for populating the inner grid. But i get an error of Cannot use only server templates in Ajax or WebService binding mode. Please specify a client template as well.

@(Html.Kendo().Grid<Customers>().Name("grid")

.Scrollable()

.Pageable().Columns(columns =>{         columns.Bound(o => o.CompanyName);         columns.Bound(o => o.ContactName);}).DetailTemplate(@<

div>@(Html.Kendo().Grid<Phones

>(item.Phones).Name("g" + item.ID).Scrollable().Pageable().Columns(columns =>{                         columns.Bound(o => o.Number);}))</

div >).DataSource(datasource => datasource

.Ajax().Read(read => read.Action("GetCustomers", "Home", new { x = "asd"}))))

I dont want the inner grid read via ajax. I want it to use the list field of returning json.

Tabindex not working correctly

Hi Everybody,

I have an ASP.NET MVC site, when I do some Razor code to add a Dropdownlist to the view.

I have the following code in my cshtml file for generating the Dropdown and it works fine.

<div class='col-md-8'>
@(Html.Kendo().DropDownListFor(m => m.CountryCode)
.DataTextField("Text").DataValueField("Value").
AutoBind(true).DataSource(dataSource => dataSource.Read(read =>
{ read.Action("GetCountries", "Member"); })).Events(f => f.DataBound("OnDataBound")))
@Html.ValidationMessageFor(m => m.CountryCode)
</div>

The output in IE 11

<span tabindex="0" title="" class="k-widget k-dropdown k-header" role="listbox" aria-busy="false" aria-disabled="false" aria-expanded="false" aria-haspopup="true" aria-readonly="false" aria-activedescendant="e8e82663-3c75-4f99-9459-7b7a41945db1" aria-owns="CountryCode_listbox" unselectable="on">

<span class="k-dropdown-wrap k-state-default" unselectable="on">

<span class="k-input" unselectable="on">Danmark</span><span class="k-select" unselectable="on">

<span class="k-icon k-i-arrow-s" unselectable="on">select</span></span></span><input name="CountryCode" tabindex="8" class="k-valid" id="MedlemLandekode" style="display: none;" type="text" value="Danmark" data-role="dropdownlist" data-val-required="Feltet er påkrævet" data-val="true"></span>

<script>

jQuery(function(){jQuery("#MedlemLandekode").kendoDropDownList({"dataBound":OnDataBound,"dataSource":{"transport":{"read":{"url":"/Felix.ASPNet.MVC/Medlem/GetCountries"},"prefix":""},"schema":{"errors":"Errors"}},"dataTextField":"Text","autoBind":true,"dataValueField":"Value"});});

</script>

<span class="field-validation-valid" style="display: none;" data-valmsg-replace="true" data-valmsg-for="CountryCode"></span>

I can see that my top element has tabindex = 0 instead of tabindex =8, this is avoiding me to tab into the dropdown list
