Grid with Custom Popup Template - Kendo Validators

Hi there,

I've read in places that the grid will automatically use Kendo Validators inside the add / edit popup, even if this is a custom form - is there any way to prevent this behaviour, so that it will just use standard MVC validation controls?

For complicated reasons, the decision has been made not use Kendo Validators inside our current MVC application - meaning that the validators on our normal forms look very different at present from those used on the grid popups.

If this behaviour can't be prevented, can the Kendo Validators be easily styled to look the same as the default MVC controls - at the minute, all we would like is a simple line of text to appear beside the control.

Thanks,

Paul

get List values on post

I am not sure how to get the values from the sortable object on the post call. Does the Viewmodel property have to match the <li> name or I the sortible object name

@(Html.Kendo().Sortable()
.For("#StandardsDirectives")
.ConnectWith("#MyStandardsDirectives")
.PlaceholderHandler("placeholder")
.Cursor("url('" + Url.Content("~/Content/Curser/closedhand.cur") + "'), default")
)

OR

@if (!Equals(Model.Document, null))
{
foreach (var standard in Model.Document.MyStandardsDirectives)
{
<li class="list-item">@Html.Label(standard.Name)</li>
}
}

Filtering grid

Hi,
I'm working on dynamic grid loaded with bounded column based on datatable definition passed in model, and grid is populated by JSON with dynamic Linq. I have a problem with setting the filtering. Sorting and grouping works just fine, but I don't know why for int type I get list which suggests it's a string. Then when filter for example the main Id with IsEqual I get an error: An exception of type 'System.ArgumentException' occurred in System.Core.dll but was not handled in user code. Then I get right results, but icon is showing that it's still searching. What could be tha cause, and how can I fix it?

Validation Message

How do you get the scheduler to display a validation message in red next to the control that has the error? I'm getting an alert with the errors to display per an example but that doesn't look very professional. See attached image.

Dependencies Needed?

I have a gantt chart now rendering on my MVC page without error. I have plumbed in the IQueryable for the Tasks Datasource but have not touched the Dependencies Datasource. The Gantt is rendering blank.

Does the Gantt chart need the Dependencies Datasource to be wired up?

View:

@(Html.Kendo().Gantt(Of IMS_2.Models.Task, IMS_2.Models.Dependency)().Name("gantt") _

.Columns(Sub(columns)

columns.Bound(Function(c) c.ID).Title("ID").Width(50)

columns.Bound("title").Editable(True).Sortable(True)

columns.Bound("start").Title("Start Time").Format("{0:MM/dd/yyyy}").Width(100).Editable(True).Sortable(True)

columns.Bound("end").Title("End Time").Format("{0:MM/dd/yyyy}").Width(100).Editable(True).Sortable(True)

End Sub) _

.Views(Sub(views)

views.DayView()

views.WeekView(Function(weekView) weekView.Selected(True))

views.MonthView()

End Sub) _

.DataSource(Function(d) d.Model(Sub(m)

m.Id(Function(f) f.ID)

m.ParentId(Function(f) f.ParentID)

m.OrderId(Function(f) f.OrderID)

m.Field(Function(f) f.Expanded).DefaultValue(True)

End Sub) _

.Read("ReadTasks", "Home")

))

Many thanks

[Solved] Grid Popup editing Save adding duplicate value in grid

Hi,

I am using Grid popup editing to add new entries, i am getting an issue when pressing Save on new add multiple times before popup disappears it adds multiple entries to the grid. Is there a way to disable Save button once a request has been send to server to create new entry so it does not send multiple times new entry.

This Happens on IE8 only

Waiting for response,

[Solved] Error 500 unhandled

Dear support team,

I have a grid which registeres an error event. When the model validation fails, the event is correctly triggered and I get a messagebox.

Next i tried to insert a dummy javascript (<script>alert('aaa')</script>) into the textbox.
MVC reacts on it with an error 500 ('a potential malicious request was detected')
However the onError event function is not triggered now.

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

.Name("kendoGrid")

.DataSource(dataSource => dataSource

.Ajax()

.Model(model => { model.Id(i => i.Id); })

.Create(create => create.Action("_Create", "Controller"))

.Read(read => read.Action("_Index", "Controller"))

.Update(update => update.Action("_Update", "Controller"))

.Destroy(destroy => destroy.Action("_Delete", "Controller"))

.Events(events => events.Error("onError")) // <----------- Register Error Event

)

.ToolBar(toolbar => toolbar.Create().Text("New"))

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

.Columns(column => {

column.Bound(i => i.Name);

column.Command(cmd => {

cmd.Destroy();

cmd.Edit();

});

})

)

<script type="text/javascript">

function

onError(e) {

alert("test");

if (e.errors) {

var message = "The folowing errors occured:\n";

$.each(e.errors, function(key, value) {

if (value.errors) {

message += value.errors.join("\n");

}

});

bootbox.alert(message);

} else {

bootbox.alert("An unknown error occured");

}

</script>

Any ideas what I've done wrong here?

btw my version is 2014.Q2

A second issue is, that I don't get a bootbox window. Instead I get a standard message box. Perhaps you have a clue on that too.

thank you,
Chris
