What is the recurrenceId field for in the scheduler and if it is important why or why is it not part of the ISchedulerEvent interface that is required for the scheduler view model???????????????????
What exactly is going on with this product?
Hi,
I am having problems getting the total count field from JSON odata using the Html Helper for the Kendo Grid. Getting the odata.count value using JavaScript is fine though but our preference is to use the MVC html helper. The following is both examples:
Using MVC Html Helper produces the following JavaScript
error: Uncaught TypeError: Cannot read property 'count' of undefined. See the Schema property for where we are trying to get the oData.count.
@(Html.Kendo().Grid<DataObject>()
.Name(
"grid"
)
.Columns(columns =>
{
columns.Bound(e => e.Field1).Filterable(
false
);
columns.Bound(e => e.Field2);
columns.Bound(e => e.Field3);
})
.DataSource(dataSource => dataSource
.Custom()
.Type(
"odata"
)
.Schema(schema =>
{
schema.Data(
"value"

.Total(
"odata.count"

Looking in the documentation there are only examples of this using javascript, are there some examples using the html helpers as well somewhere? Any pointers in the right direction are welcome.
thanks,

Hi,
I did search for your private bower repositories. The UG link is broken from your site.
http://docs.telerik.com/kendo-ui/install/bower#install-kendo-ui-professional-bower-package
404 - File or directory not found.​​
Also the same for this below page too.

Hi,
we try to update with the VS Extension by clicking "Upgrade Wizard" from our current 2015.2.805.545 Dev Version to the newest 902 version.
After a few minutes Visual Sutdio freezes on "Copy Globalization files" from Telerik.
I try to wait the whole night, checked for this this morning but no change.
Any ideas?
I working with the telerik grid a since a few weeks.
It seems that the Bound() Method of the MVC Grid ignores the Type when I write Bound(type, name).
When I have a model binded grid, it works perfectly:
@(Html.Kendo().Grid<Web.Models.Consumption.PDCAModel.PDCAActionplanModel>()
.Name("PDCAActionplanGrid")
.NoRecords(@ResourcesLocal.Resources_Energy_PDCA.NoActionplanAvailable)
.Columns(col =>
{
col.Bound(x => x.PlanCreatedAt).Title(ResourcesLocal.Resources_Energy_PDCA.PlanCreatedAt).Width(200).Format("{0:dd.MM.yyyy}");
col.Bound(x => x.PlanstringTranslated).Title(ResourcesLocal.Resources_Energy_PDCA.Planstring);
})
.Events(e => e.DataBound("PDCAActionplanGrid_DataBound"))
.ClientDetailTemplateId("template")
.DataSource(ds => ds
.Ajax()
.Read(read => read.Action("DataSourcePDCAActionplanGrid", "Consumption"))
)
)
Here my column "PlanCreatedAt" is a datetime which will be shown perfectly.
Now I want to use a dynmic binded grid with a DataTable as DataSource:
@(Html.Kendo().Grid<dynamic>()
.Name("CompilationLogicGrid")
.NoRecords()
.Columns(col =>
{
col.Bound(typeof(DateTime), "Date").Filterable(false).Title(ResourcesGlobal.GlobalResources.Datum).Format("0:dd.MM.yyyy");
})
.Filterable(filtering => filtering.Enabled(true))
.Sortable()
.DataSource(dataSource => dataSource.Ajax()
.Read(read => read.Action("DataSource_CompilationLogicGrid", "Consumption"))
.Sort(x => x.Add("Date").Descending()))
)
There it seems, that the binding will completly ignored. The output is either a plain string which I wrote in the format 0:dd.MM.yyyy or a the plain output of the json response
The JSON Response is on both grids exactly the same: /Date(xxxxxxxxxx)/
I am using the scheduler binding to local data from my viewmodel. The scheduler is set to TimeZone of "Etc/UTC" and all the dates are stored as UTC however they are all adjusted in the scheduler. How can I turn off scheduler timezone adjustments. There should be nothing to adjust to since everything is UTC!
Honestly, I keep running into problem after problem with these products and I think that $2,000 was a big mistake.
The problem is I'm not able to pass the date selected by user from Kendo Date time picker in View to Controller using ajax call. Any help or input would be much appreciated. When I put the debugger, I found that control is just passing over it but not hitting the Action method in the Home controller.

Hi
I have question to you how I can pass id to my custom popup.
The whole problem is that I need to load specific data to my dropdownlist. and I need pass id off item which is in edition.
I tried:
@Html.Kendo().DropDownListFor(m => m.Level).DataTextField(
"Text"
).DataValueField(
"Value"
).DataSource(dataSoruce => dataSoruce.Read(read => read.Action(
"LoadPosibleOrderDll"
,
"ProductCategories"
,
new
{ categoryId = Model.ParentCategory })))
model of tree list
.Model(model => { model.Id(p => p.Id);
model.ParentId(p => p.ParentId);
model.Field(p => p.Id).Editable(false);
model.Field(p => p.Level);
model.Field(p => p.ProductCategoryOrder);
model.Field(p => p.Parent.Name);
model.Field(p => p.OrderPosibilities );
})​
I am storing the values selected with my Cascading ComboBoxes in the local storage so it will remember what they have chosen. The problem is when the browser back button in clicked, the Cascaded combobox's Datasource is empty so when I set the value it just puts the # in the drop down instead of showing the selected item.
From what I can tell it is not calling the read method when the back button is pressed and is not cacheing the list since I am using ServerFiltering. I have even tried manually calling the read method of the datasource in JavaScript but to no avail.
How can I get this list to re-populate when the back button is used?
