Hi!
I have 2 datasources: for multiselect and for dropdownlist, and 1 datasource for insert data into db from multiselect and dropdownlist.
But as result i have new record in database: id_client: blank and id_board: (needed value).
When i do "alert(required.value() + optional.value() )" i getting needed values. Why is blank posted data in field "id_client"?

**** I WAS INCORRECT IN MY ASSUMPTION THAT DATA WAS LOST WHILE SCROLLING.  PLEASE DISCARD THIS POST.

I have a grid in cell editing mode with virtual scrolling with a dataSource using batch updates.  When the virtual scrolling requires new data to be fetched from the server, any unsaved changes to the current data are lost.  That makes sense because the dataSource is only maintaining a portion of the total data at any given scroll position.

I would like to present the use with a message like "You need to save changes before scrolling any more..." and give them the opportunity to either save or cancel the existing changes or simply stop the scrolling until the either save or cancel.

I tried binding to the requestStart event that is triggered by the dataSource's undocumented prefetch method that is called while virtual scrolling.  I can prevent the new data from being fetched by calling event.preventDefault() in the handler but the grid is left in a disabled state via a kendo progress indicator that was initiated somewhere along the way.

The relevant code in kendo-ui that I've been examining include VirtualScrollable._scroll() and DataSource.prefetch().

Q: Is there a more elegant way of doing this?  I know I could use paging and have more control but virtual scrolling is just much cooler IMO.

Thanks

I have a requirement to disable the ComboBox under certain conditions (or make readOnly). Part of the requirement is the appearance of the ComboBox; the dispaly area must have a light Grey background and the Text must be black. However, while I can make the background lightgray, nothing I do works for setting the text to Black.

I also have the same problem with DatePicker widgets.

So how do I go about keeping the text color black when the a widget is disabled?

Hi,

we want to change the title in navbar according to some global variables.
after navigating to another application page via app.navigate('ksettings.html') it's not possible to call title method of the navbar, eg.

$("#photonavbar").data("kendoMobileNavBar").title( g_models.ParamsVM.valSpecNames.join(' ' ) );

because $("#photonavbar").data("kendoMobileNavBar") is undefined.
Event indicating all kendo structures are initiated would be usefull.

How to track that page was succesfully navigated and all kendo structures are instantiated?

Thanks in advance

Scenario:

Kendo control is in a partial view.

Page loads to homepage, no kendo control.

User clicks to view that has a kendo control, we pull that partial view down and inject it into the container.

Some kendo controls do not load at all (calender), and in the scheduler's case, does not render the scheduled events.

I've tried using the deferred feature then calling Kendo().DeferredScripts(), but that only results in the scheduler not rendering at all.

The grid renders fine when dynamically injected, however.

The deferred feature documentation says the default functionality is for the control's initialization scripts to fire immediately after the control is rendered. If this is the case then injecting a partial view with kendo controls within should not be a problem.

However, all of the controls that I've tested work fine when they are rendered during page load, but only the grid works as expected when injected after page load.

I'm using a Kendo Mobile View and I've set the data-zoom attribute to true ("data-zoom = true") so that my view can Pinch and Zoom. 

Is there an attribute or css style that I can set to limit the size in which the Pinch and Zoom resizes the contents? I want to set a max and min size. 

I want to make my view so that it can zoom in but I want to constrain the view so that it doesn't get smaller than 100% of the viewport width. I like to set the min-width equal to the viewport width in some way. How do you do this?

Any help would be greatly appreciated. 

Hi,
We have the following datasource
I only want it to hit the server "getMessagesFromServer()" if there is no cache (which is working) or when the user "pulls to refresh" in the listview e.g.
How can I tell messages.read that the user has forced a refresh and it needs to go to the server to get the data rather than the cache.

Thanks in advance

I have an issue where I have a scheduler which extends off the bottom of the page and when you click on it, the whole page shifts up, so that the top, left corner of the calendar is at the top of the page.  Is there a way to prevent the page from shifting?

When you double-click to bring up the editor, it ends up opening at the wrong time slot, because it shifted between clicks.

Please see that attached.  We have a few donut charts and want the labels on them.  We have done what we can to reduce the size, but the labels and chart title still seem to get cut off (see attached pictures).  This is in a responsive UI, and it seems the labels are not always counted when using the "$(this).data("kendoChart").redraw()" method.
