Hi,

I'm not sure if this is a bug or just a misunderstanding on my part. I'm also putting this post here, but it may be more relevant for the SPA section!

When using a dropdownlist inside a view (rendered as part of an SPA layout), the following element is created at the foot of the body (as well as the normal markup):

<div style="display: none; position: absolute;" data-role="popup" id="dropdownlist1-list" class="k-list-container k-popup k-group k-reset"><ul aria-live="off" id="dropdownlist1_listbox" aria-hidden="true" role="listbox" tabindex="-1" style="overflow: auto;" unselectable="on" class="k-list k-reset">

On a view change, using layout.showIn(), I was to understand the the view and all its child elements would be removed from the DOM. As it is, these elements remain - if the view reference is retained it would appear that only one instance is created if the the view reference is recreated, a duplicate is formed when the view is rendered.

The JSFiddle here demonstrates the issue hopefully. Obviously if there are a lot of views being used with many dropdownlists, then the capacity for many of these remnants to be created could be significant. I haven't done exhaustive testing, but this doesn't seem to happen for (for example) the grid.

Grateful for any assistance!

Many thanks,

J.

mismatched quotation marks around the word groupable in kendo.all.min.js

Not sure what version of kendo I have, but the javascript parser add-in for Visual Studio detected an anomaly in the kendo.all.min.js file -- in one place the word groupable is quoted with a single quote on the left end and a double quote on the right end.

mismatched quotation marks 'groupable" in kendo.all.min.js

I'm not sure what version I've got, but there's a mismatched quotation mark (single on one end , double on the other) in kendo.all.min.js.

I tried to attach a PNG showing where it is, but there's an error message "Invalid post content".

Thanks

GridEditMode.InLine after Edit then Update - Grid Stays In Edit Mode

Title says it all. I am editing a record inline. When I hit update, the request to the server occurs, the record is saved and the response is returned. However, the Grid does not acknowledge the fact that the AJAX request was successful. So the Grid stays in edit-mode. If I cancel then refresh the grid, the row shows up as it should (saved). No errors are occurring on the server or client.

I'm using the ASP.NET MVC Wrappers - AJAX.

<div style="width: 700px">

@(Html.Kendo().Grid<RoleGridModel>()

.Name("grdRoles")

.Columns(columns =>

{

columns.Bound(r => r.Name).Width(200);

columns.Bound(r => r.Description).Width(300);

columns.Command(command => {

if (security.CanAdd || security.CanUpdate) command.Edit();

if (security.CanDelete) command.Destroy();

}).Width(200);

})

.Groupable(grouping => grouping

.Enabled(false))

.Events(events => { if (security.CanAdd && !security.CanUpdate) events.DataBound("function() { this.table.find('.k-grid-edit').hide(); }"); })

.DataSource(dataSource => dataSource

.Ajax()

.Model(model => model.Id(r => r.RoleId))

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

.Read(read => read.Action("Index", "Roles", new { area = "Setup" }))

.Create(create => create.Action("Create", "Roles", new { area = "Setup" }))

.Update(update => update.Action("Edit", "Roles", new { area = "Setup" }))

.Destroy(destroy => destroy.Action("Delete", "Roles", new { area = "Setup" }))

.Sort(sort => sort.Add(r => r.Name).Ascending())

.PageSize(10))

.Filterable(filtering => filtering

.Enabled(true))

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

.Pageable(paging => paging

.Enabled(true)

.Info(true)

.PageSizes(false)

.Refresh(true))

.Scrollable(scrolling => scrolling

.Enabled(false)

.Height(400)

.Virtual(false))

.Sortable(sorting => sorting

.Enabled(true)

.AllowUnsort(false)

.SortMode(GridSortMode.SingleColumn))

.ToolBar(toolbar => { if (security.CanAdd) toolbar.Create(); })

)

</div>

[HttpPost]

public ActionResult Edit([DataSourceRequest] DataSourceRequest request, RoleGridModel model)

{

if (ModelState.IsValid && model != null)

{

try

{

Role r = Mapper.Map<RoleGridModel, Role>(model);

r.AppContext = this.AppContext;

r.SubscriberId = this.AppContext.SelectedSubscription.SubscriberId;

r.SubscriptionId = this.AppContext.SelectedSubscription.SubscriptionId;

r.ModifyDate = DateTime.UtcNow;

r.IsNew = false;

r.IsMarkedForDelete = false;

r.HasChanges = true;

r.Save();

}

catch (Exception ex)

{

LogException(ex);

ModelState.AddModelError("", "Unable to update role. " + ex.Message);

}

return Json(ModelState.ToDataSourceResult());

}

can NumericTextBox be used with USA 5-digit zipcodes (actually a string of digits not a number) that can begin with leading zero?

US zipcodes come in two varieties, a 5-digit code (e.g. "90210") and a 5-digit-hyphen-4-digit code (e.g. "19063-2345"). I am interested in the former.

Both formats can begin with a leading zero, e.g. Princeton NJ zipcode is "08540".

Can the NumericTextBox be made to preserve the leading zero, and to display the value as a string of five digits without commas, decimal points?

I'm looking to adapt the NumericTextBox into a masked text box that accepts a string of five digits.
Does KendoUI have a masked text box that I've overlooked?

Thanks

Get field name in filterable UI javascript function

Hi

I am using the following syntax to use a the javascript function for adding a dropdown to a filter within a column of a grid:

columns: [

{

title: "Typ",

field: "FileExtension",

width: 50,

filterable: {

ui: dropDownFilter

}

},

{

title: "Titel",

field: "Title",

width: 360,

filterable: {

ui: dropDownFilter

}

},

Within the javascript function "typeFilter" I would like to know the column or better the field of the column

to build a javasript function that can work dynamically for several columns.

So is there a way to get the field ("FileExtension") within the javascript function or a way to pass it down to it?

function dropDownFilter(element) {

element.field ?????

}

Thanks for your help!

Best regards,

Pascal Hohensträter
