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

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.

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.

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.

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.

But It is not working as it should be and not showing Drop Down List for Category Column in Edit mode and show numeric text box and text box instead
I'm using Northwind Database as in your example and I didn't change a lot in your code but it is not working .. so could you help to fix this issue and make it work as your example.

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.

Hi,
I have two custom editors in my Grid.
One is a simple dropdown for a "ForeignKeyColumn" - using UIHint("MyEditor") this works fine in Inline as well as in PopUp edit mode.
An other column using a "MultiSelect" works in Inline but not in PopUp edit mode.
In PopUp the whole Column is not displayed.
It is something like the territories in Northwind, where on Record can belong to multiple Territories.
I works fine in Inline - but (for other reasons) I would need PopUp.

Hi, I am using Kendo for ASP.Net MVC version 2015.2.264 using the Blue Opal theme. I have a checkbox input which is not "checkable" when bound to a model property via the @CheckBoxFor razor syntax. It renders correctly using the Kendo assigned theme, but does not allow you to check it even though it is not disabled.
This works:
<div style="display:block;">
<input type="checkbox" id="chkIntegrated" class="k-checkbox" name="Integrated">
<label class="k-checkbox-label" for="chkIntegrated">Integrated 2</label>
</div>
This does NOT work:
<div style="display:block;">
@Html.CheckBoxFor(Function(m) m.Integrated, New With {.class = "k-checkbox", .Id = "chkIntegrated"})
@Html.LabelFor(Function(m) m.Integrated, New With {.class = "k-checkbox-label"})
</div>
I have attached the test html page which illustrates this. Any ideas?
