Multiselect configuration with filter and noDataTemplate throws error

Using this example https://demos.telerik.com/kendo-ui/dropdownlist/addnewitem and changing the kendoDropDownList to kendoMultiSelect, i receive the error below because the instance.filterInput is not defined on the widget instance. According to your docs these two property configurations are supported. How can I get the multiSelect to have a filter?

Item Template consuming from MVC DisplayTemplates

Hi,
i'm struggling with the Kendo ListView.
I want to define the Templates with MVC standard DisplayTemplate and EditorTemplates.
But since the support from Telerik does not understand what i want and always pointing me to their demos - which are uselsse - i came here, hopefully there is somebody who can give me an answer about that.
we simply want to use Item Templates for the ListView control.
i dont want to use the Telerik Template language, since its not possible to access complex types (Navigationproperties).
has anybody an idea if its possible in general?
and if yes - are there any examples around?
thanks & best regards
Mike

[Solved] column reorder event delay

Hi, I'm trying to save grid on most user actions but the column reorder event seems to fire before the actual columns are reordered. To accommodate this oddness I've added setTimeout around the saving of grid options. Is this delay a known bug?

function saveUserAdministrationGridState(arg)

{

if (isLocalStorageAvailable())

{

// column reordering firing delayed, so we must delay our saving of options

// hack source: http://stackoverflow.com/questions/21270748/kendo-grid-saving-state-in-columnreorder-event

setTimeout(function () {

localStorage[customGridOptionsLocalStorageKey] = kendo.stringify(grid.getOptions());

}, 5);

}

Grid, Filter and Page

Hi,
I use Kendo UI with Angularjs, I have a grid with datasource calling remote web api and wih just server paging active (in backend I have to call a third part web service with page parameter). I want to use sort and filter on client side. Sort on columns works excellent but when i change page and try to filter on a column value in that page (the second or more), the datasource call again my backend passing page=1 and not the page's number in which i use the filter. I have to build a more advanced filter on the page so i need that filter on columns works locally without changing the page. Sort call WS with the same page's number. A workaround could be passing the current page in a different parameter to the WS, eventually could you help me with that?

Thanks

Validation editors not accessible from last column.

This appears to be a bug as the functionality is essentially broken. The validation editors including those shown in the demo, will appear offscreen and inaccessible if in the last visible column in a horizontally scrolling spreadsheet.

See dojo here.

Steps to reproduce:

Create a spreadsheet that has a horizontal scroll.
In the last column apply cells with validations and/or a custom editor.
Render the spreadsheet and scroll to the right.
Notice the editor buttons appear off-screen, there is no way to access them.

Expected result:
The buttons should appear on the left of the cell instead of the right if they are not accessible (that is, they fall on the last visible column).

Update Datasource After Import

Hi

I have a spreadsheet component, with a datasource. I am exporting a dataset from the spreadsheet, changing it in Excel, and then reimporting it. After I import data, if the imported data has more records than the current dataset, the dataSource is not updated so when I save nothing happens.

In my save, I use dataSource.hasChanges to check if we have changes in the dataset. This is true, even if I have only added a record. However - dataSource.data().length is still the original size. I have tried with dataSource.sync(). Is there something I am missing?
