I creatred a new project using the Telerik template. By default, the IAntiforgery token was injected. In order to use that token, the Datasource invokes it this way:
.DataSource(ds => ds.Ajax()
.Read(r => r.Url("/Index?handler=Read").Data("forgeryToken"))
That .Data references to a script like this:
<script>
function forgeryToken() {
return kendo.antiForgeryTokens();
}
</script>
Question... if I have additional data to include, how is the forgeryToken included?
I use a script like this:
function gridGetData() {
//alert("grid.gridGetData");
//alert("customerId: " + customerId);
var groupId = $("#groupId").val();
if (groupId != null && groupId !== 0) {
var firstName = $("#firstNameFilter").val();
var lastName = $("#lastNameFilter").val();
var isActive = $("#isActiveOptions").val();
//alert("gridGetData - firstName: " + firstName);
//alert("gridGetData - lastName: " + lastName);
//alert("gridGetData - isActive: " + isActive);
return {
customerId: customerId,
customerUniqueId: customerUniqueId,
groupId: groupId,
sessionId: sessionId,
firstNameFilter: firstName,
lastNameFilter: lastName,
isActiveFilter: isActive
};
} else {
return @Html.Raw(Model.GetIndexData());
}
}
Is it possible to do use a dynamic editor on a column with C# wrappers, like the example below does for jquery?
https://docs.telerik.com/kendo-ui/knowledge-base/grid-use-dynamic-editor
How can I achieve similar functionality?
I have a simple Preference object that can have different types of values. (Boolean, String, Number, etc).
The preference object has a DataType that tells it what type for each row. I would like to use this value to determine what editortemplate to use.
Thank you very much for your help.
I based the implementation on the example video about TagHelpers. But no data is displayed. A call to the URL (https://localhost:44337/Suppliers/Read) provides data. What am I doing wrong?

I am trying to have a treelist with the new functionality and the drag&drop functionality.
I have enabled the drag&drop functionality but the treelist does not update the relationship after the drop ends.
On another post it was suggested to set Autosync on the datasource. However this creates the problem that when creating a new item it is automatically saved without the user been able to enter values first. This is not acceptable for my situation because there are some fields that are mandatory and I do not want to use a default value. So Autosync is out of the question.
On another post it was suggested to handle the DragEnd and call manually the sync on the datasource. However this is not handle as expected. Because my method sometimes should fail (The datasource error event is called). And after the error event is handled the treelist is in an incorect state since the dragged item is displayed with the wrong parent (In the Autosync if an error occured the drop would be canceled and the item returns to the initial position)
So my question is how can I have the two functionalities? (Autosync-ing only drag&drop and leave the create without autosync)
Hello,
I have scheduler that has editable events. When editing an event the template that i provide loads up another scheduler. The scheduler within the editor template needs to have it's date set to match the start date of the event i'm editing. So far i can get this working by using a custom binder to bind my date in the editor model to my scheduler.
EditorTemplate:
@(Html.Kendo().Scheduler<
TaskViewModel
>()
.Name("staffAvailability")
.Height(300)
.HtmlAttributes(new {data_bind = "bindDate:start, visible:Staff.length" })
.Timezone("Europe/London")
.Editable(false)
.AutoBind(false)
.Views(views =>
{
views.TimelineView(timeline =>
{
timeline.Footer(false);
});
})
.DataSource(dataSource => dataSource
.ServerOperation(true)
.Read(read => read.Action("ListStaffSessions", "Scheduler").Data("getStaffAttendance"))
).Events(e => e.DataBound("dataBoundAttendanceControl").DataBinding("dataBindingAttendanceControl"))
)
javascript:
kendo.data.binders.widget.bindDate = kendo.data.Binder.extend({
init: function (widget, bindings, options) {
kendo.data.Binder.fn.init.call(this, widget.element[0], bindings, options);
},
refresh: function () {
var that = this,
value = that.bindings["bindDate"].get()
var scheduler = $(that.element).data("kendoScheduler");
scheduler.date(value);
}
});
The issue i have is i don't want the scheduler to read from my data source on load, so i've specified that autoBind should be false on this scheduler however because i'm trying to bind the date this way that results in a change event being fired and my data source gets read.
Is there any way for me to provide the scheduler in my editor template a start date via the html helpers to avoid having to write a custom binder?
Hi,
I've created a grid to with i've added several dropdowns as editor controls I have added the relevant UIHints etc... and the drop downs are shoing and being populated correctly however when selecting a value from one of the dropdows I get an error that shows up in the console complaining that the property is null and when the model is passed through to the update method the values being passed are those of the original data and not the updated fields
This is my grid:
@(

columns.Bound(t => t.StandardFee).Title("Standard Fee");
columns.Bound(t => t.PremiumFee).Title("Premium Fee");
columns.Bound(t => t.TheoryTestCode).Title("Theory Test Required")
.ClientTemplate("#= TheoryTestCode == null? '' : TheoryTestCode.Description #");
columns.Bound(t => t.FullTestRequired).Title("Full Test Required")

My editor controls (obviously in separate partial views named the same as the ui hint):
@(Html.Kendo().DropDownList()
.Name("FullTestRequired") // The name of the widget has to be the same as the name of the property.
.DataValueField("Id") // The value of the drop-down is taken from the TheoryTestCode Id property.
.DataTextField("Category") // The text of the items is taken from the TheoryTestCodes Description property.
.BindTo((System.Collections.IEnumerable)ViewData["DriverTestTypes"]) // A list of all TheoryTestCodes which is populated in the controller.
.AutoBind(false)
)
@(Html.Kendo().DropDownList()
.Name("TheoryTestCode") // The name of the widget has to be the same as the name of the property.
.DataValueField("Id") // The value of the drop-down is taken from the TheoryTestCode Id property.
.DataTextField("Description") // The text of the items is taken from the TheoryTestCodes Description property.
.BindTo((System.Collections.IEnumerable)ViewData["TheoryTestCodes"]) // A list of all TheoryTestCodes which is populated in the controller.
.AutoBind(false)
)
The following is where i populate the dropdowns :
public
async Task<ActionResult> Index()
{
ViewData[
"TheoryTestCodes"
] =
new
List<TheoryTestCodeViewModel> {
new
TheoryTestCodeViewModel { Description =
"MotorBike"
, Id = 2, TestCode = 2 },
new
TheoryTestCodeViewModel { Description =
"Car"
, Id = 1, TestCode = 1 }
};
ViewData[
"DriverTestTypes"
] =
new
List<FullTestRequiredViewModel>
{
new
FullTestRequiredViewModel { Category =
"A1 Off Road"
, Id = 2 },
new
FullTestRequiredViewModel { Category =
"Test"
, Id = 3 }
};
ViewData[
"DriverTestTypesDefault"
] =
new
List<FullTestRequiredViewModel>
{
new
FullTestRequiredViewModel { Category =
"A1 Off Road"
, Id = 2 }
};
return
this
.View(
"DriverTestType"
);
}
The console error that is displaying is "Uncaught TypeError: Cannot read property 'FullTestRequired' of null" which happen on the selection of an item from the dropdown
I can't see what is wrong so any assistance would be gratefully appreciated :)
When I add an editor to a form either directly or through the new wizard, it does not unmask the field. Please let me know what am I doing wrong.
...
item.Add()
.Field(field => field.Zip)
.Label(label => label.Text(
"Zip"
))
.Editor(editor => editor.MaskedTextBox().Mask(
"00000-9999"
).UnmaskOnPost());
...
I am trying to use either the new Form or Wizard widget as a popup editor, but it does not bind the data item to the widget.
Is this supported? Is there a way I can archive this?
Thanks
