Questions on UI for ASP.NET MVC Forum

I am evaluating Telerik ASP.NET MVC for a small shop of C# developers with minimal to no javascript background. In particular the DropDownList event demo (but the same problem applies to many of the demos). The demo link here:

http://demos.telerik.com/aspnet-mvc/dropdownlist/events

Now a typical use case for this component for an ASP.NET MVC developer would be to:

1.Load the DropDownList from an MVC Controller

2. Detect a selection changed event

3. Do something with the selected value in an MVC context, such as having an ActionLink in a Razor view to pass the selected item back to the mvc controller as an action param, or calling a GET on an MVC controller from JavaScript with the selected value in order to demonstrate the "full round trip"

Instead these demos show the bare minimum (outputting to client side log). It would be nice for these demos go the extra mile to show some real non-trivial use-cases in the example code. Sure, you can find the answer to the above stuff by spending half a day in the forums hoping someone else had the same question and searching stackoverflow, etc, but for us the quality and depth of the example code will be the deciding factoring in purchasing a license, thanks

kendo validation does not work the second time

I have a page where i use MVC validation when I click on submit on my form. basically it uses:

@using (Html.BeginForm("InsertData", "DataPage", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
@Html.ValidationSummary(false, "Insert Data unsuccessful.")
...

one of the fields inside this form is:

@Html.Kendo().DropDownListFor(m => m.DType).BindTo(Models.DType.GetDTypes())

This DType business object has the [Required] data attribute on it,and it works great the first time. If i select a DType from the dropdown, then the submit works fine. if i don't select it, then i get a validation error in the summary above telling me i need to enter a value.

Great, no problems so far. The problem though is now i have a validation error, so i correct it on the form by selecting a DType. This does nothing. I click submit, it tells me i still haven't entered a DType value. Putting a breakpoint in the controller confirms that it's not recieving a DType value, despite the fact that i selected one.

If i change the dropdown to a basic @Html.DropDownListFor ... , it works fine, so i know the problem is with the kendo control. What am I doing wrong here, and how can i fix it?
Thanks

Custom button in kendo grid toolbar which works as save changes button (send edited rows)

Hi,

I want to use custom button in kendo grid toolbar which work as save changes button (i.e send edited list of rows),

I have a grid which has a checkbox column "Select" , so when the checkbox is checked the row comes in edited state, and by simply pressing the Save Changes button I could send edited rows to controller method.

But problem is that I need two buttons (i.e Approve and Reject which needs to work same as the "Save Changes" button does) to do different tasks on selected records.

Attached here is snapshot.

Scheduler finished loading event

I have tooltips that I'm trying to initialize and I can't get it to work on the initial load of my view. The function is firing but it seems like the events have not been created yet on the DOM so I'm not able to attach a click event to them. I'm using a custom template with a class ".app". I'm doing a $('.app').each to find all my events on the scheduler. If I click one of the views or reload it with a button click it works. just when it officially loads for the first time. Any help would be great.

Editor changes on focus

Hi,

I have a grid with several ForeignKeyColumns.

In IE11 when I click on a column the dropdown opens (for a blink) - the input moves a bit - and after that it works as expected.
I can also Tab through the fields - if I focus them first they move a bit (without opening) and after it they work normal.

In chrome the "initial moving and ''blink' opening" does not occur.

This only happens in IE when the column is to small to display the whole dropdown.

Select nothing in multiselect causes error

Hi,

I use a MultiSelect to choose several values in an m:n relation.

Everything works as expected as long as I select one or more values.
But when I select nothing I get the following error:

0x800a138f - Laufzeitfehler in JavaScript: Die Eigenschaft "length" eines undefinierten oder Nullverweises kann nicht abgerufen werden.

The failing code is for(n=0,i=e.length;i>n;n++)o+=n%2?s(e[n]):a(e[n]),r._data.push(e[n]);return o}

This happens only when I add a new record.
If I edit an existing one it is possible to remove the formerly chosen element and update after this.

I initialize the field via model.Field(p => p.Salads).DefaultValue(new List<EECanteen.Models.FoodItem>());

To explain my problem - I want to edit meal offerings for a day and can choose from zero or more salads.

TimelineView setting number of days/timeslots

In the webforms control I was able to set the Timeline to a specific day then set how many days I wanted to see after that day. I did this by setting the NumberOfSlots property. I have not been able to find this property in the MVC Scheduler. How do I get this same behavior with the MVC Scheduler control.

thanks for the help.
