Kendo Grid: How to keep scoll position after calling sync (with Batch property set to true)

We have a Kendo Grid, shows many records with Batch property set to true.
Sync() is called after user modifies data, but then the scroll always moves up to the first row.

$('#grid').data('kendoGrid').dataSource.sync()

How can I prevent the scroll from moving up to the first row?
I have set focus to the current cell by calling, but it doesn't work (from this example: http://dojo.telerik.com/@Alexander/Ezoh/3):

this.current(cell);
grid.table.focus();

Thank you very much in advanced.

Inline editing validation with drop-down list fails

I've got a grid, which uses in-line editing on the sub-grid for the linked hierarchical data.

When just using a text box, the validation message display, and prevents entry of a blank value, but when I replace it with a drop-down list editor template, the validation fails to fire, causing an error message to be displayed (from the controller) when the record tries to save. This is strange, as when I do similar drop-down lists with pop-up edit forms, the validation works fine.

The grid:-

@(Html.Kendo().Grid<CMS_2013.Models.ApportionmentScenario>()

.Name("Grid")

.Events(e=>e.Edit("onEdit"))

.Columns(columns=>

{

columns.Bound(o => o.ID).Title("ID");

columns.Bound(o => o.FormattedDateTime).Title("Created");

columns.Bound(o => o.ScenarioName).Title("Name");

columns.Bound(o => o.CreatingUser).Title("User");

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

})

.ClientDetailTemplateId("detailsTemplate")

.ToolBar(commands=>commands.Create())

.Editable(editable=>editable

.Mode(GridEditMode.PopUp))

.DataSource(dataSource=>dataSource

.Ajax()

.Model(m=>m.Id(p=>p.ID))

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

.PageSize(10)

.Read(read=>read.Action("ReadScenarios","Apportionment"))

.Create(create=>create.Action("InsertScenario","Apportionment"))

.Update(update=>update.Action("UpdateScenario","Apportionment"))

.Destroy(delete=>delete.Action("DeleteScenario","Apportionment"))

)

.Pageable()

.Sortable()

.Filterable()

)

</div>

<script id="detailsTemplate" type="text/kendo-tmpl">

@(Html.Kendo().Grid<CMS_2013.Models.ApportionmentData>()

.Name("Data_#=ID#")

.Columns(columns=>

{

columns.Bound(o => o.FormattedDateTime).Title("Date");

columns.Bound(o => o.Purchaser).Title("Purchaser");

columns.Bound(o => o.Apportionment);

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

})

.ToolBar(commands=>commands.Create())

.Editable(editable=>editable

.Mode(GridEditMode.InLine))

.DataSource(dataSource=>dataSource

.Ajax()

.Model(m=>m.Id(p=>p.ID))

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

.PageSize(10)

.Read(read=>read.Action("ReadData","Apportionment", new { SID = "#= ID #" }))

.Create(create=>create.Action("InsertData","Apportionment", new { SID = "#= ID #" }))

.Update(update=>update.Action("UpdateData","Apportionment"))

.Destroy(delete=>delete.Action("DeleteData","Apportionment"))

)

.Pageable()

.Sortable()

.ToClientTemplate())

The editor template for the purchaser field (PurchaserEditor.cshtml):-

@(Html.Kendo().DropDownList()

.Name("Purchaser")

.DataTextField("ShortName")

.DataValueField("Purchaser")

.OptionLabel("Choose Purchaser")

.HtmlAttributes(new { style="width:180px;"})

.DataSource(source=>source

.Read(read=>read.Action("GetPurchaserLookUpList2","ManualData"))))

The object meta data:-

public class ApportionmentDataMD

{

[Required, StringLength(6)]

[UIHint("PurchaserEditor")]

public object Purchaser { get; set; }

[Required]

[UIHint("ApportionmentPercent")]

public object Apportionment { get; set; }

}

Thanks

Everything Works with the exception of Filtering

Hello All!

I have setup a page that uses the Kendo UI Grid (code attached below). Everything seems to be working fine with the exception of filtering. I've looked at the documentation and browsed through the forums, but must have completely missed the answer. Can anyone take a look and offer any help? Thanks for your time in advance!

Call Select-Method after onChange of Dropdownlist

Hi everybody,

I've the following problem: I tried to add a dropdownlist to a Html.Telerik.Grid in the Toolbar. I did it like this:

01..ToolBar(toolbar =>

02. {

03. toolbar.Template(@<text>

04. <div class="toolbar">

05. @Html.DropDownList("SelectedShopCategoryId",

06. Model.AvaiablePriceLists,new

07. {@onchange="onChange(this.value);"})

08. </div>

09. </text>);

10. }))

Now in the onChange-Event of the DropDownList I want to fire the Select-Command of the grid from this piece of code:

1..DataBinding(dataBinding =>

2. dataBinding.Ajax().Select("ProductList", "Event", new RouteValueDictionary {

3. { "selectedIds", Model.SelectedProductIds } }))

How can I achive this behaviour or how can I call the action in the controller with Javascript/Ajax?

Greetings

Alexander

loading existing tree data on-demand and on page load

Hi

This is probably a really dumb question, but can anyone point me to a simple example of how I can automatically select and expand nodes on my tree on page load?

Our tree contains a great deal of data, so we're using load on-demand. I need to create a page that allows users to edit an existing tree, but I can't seem to work out how I can load on-demand only the ticked nodes and their siblings.

Globalization on Kendo grid

Hi,

To allow the user to change the website language, I've added globalization on my grids following the instructions here.

~/Scripts/jquery.min.js

~/Scripts/kendo.all.min.js

~/Scripts/kendo.aspnetmvc.min.js

~/Scripts/cultures/kendo.culture.fr-BE.min.js

The last instruction before the end of head tag is :

<script>

kendo.culture('@culture');

</script>

I checked, all files are included in that order. However the grid messages and date en decimal formats remain in english as you can see in attached screenshots.

Note:

The user can change language on the fly (I've seen solutions using directive <globalization> in web.config. I think I cannot use that)
The language change but the date format must remains the same (comma for decimals and dd/MM/yyyy as date format)

I use editor template to edit grid inline but I cannot format the value that way. Am I missing something ?

Get rid of colors on the Agenda view

I'm trying to display the Agenda view on the Scheduler without the colors.

I have tried using a custom event template like so (edited for brevity):

Html.Kendo().Scheduler<Project.Models.ViewModel>()
.Name("Scheduler")
.EventTemplate(
"<div class='agenda-template'>" +
"<p>#= title #</p>" +
"</div>"
)

However, this does not get rid of the colors on the Agenda view. Suggestions?
