In my application I have used 

ModelState.AddModelError("Fieldid", "ErrorMessage");

first time on button click it is validating fine, 

from second time(without refreshing the page) I give another wrong input and it still validate but error message on UI didn't show.

tried debugging the code didn't found any issue,

tried to see console on web browser , no error shows.

Howdy!

I have a scenario in which I need to run some code when the item selected in a foreign key column in my grid is changed when it is being edited.

I can access other columns' editors without issue, but for some reason, every time I attempt to grab the editor for the foreign key column, it comes up as null.

For instance, I can use the following to grab the numeric text box for the edited row (in the Grid's on-edit event) with no issues:

var mcEditor = e.container.find("input[name=MoistureContent]").data("kendoNumericTextBox");

But, the only thing I can get to return as an object in the same on-edit event of the grid is the following:

var proctorEditor = e.container.find("input[name=ProctorReportId]");

I've tried using the following with no luck:

var proctorEditor = e.container.find("input[name=ProctorReportId]").data("kendoDropDownList");
var proctorEditor = e.container.find("input[name=ProctorReportId]").data("kendoComboBox");

We are using a GridColumnSettings for a grid view.

Because the data is text heavy, we are using a popup when editing it.

This puts the Save and Cancel buttons at the bottom of form.  We have a user who doesn't want to scroll down to Save. (We already have had to put Save at the top of another form with links to Top.)

Is there any way to force the buttons to appear at the top or in both places? Any suggestions welcome. 

These are the basic settings we are using:

on the grid page:

 @(Html.Kendo().Grid<TITLE_PATTERN_1>().Name("grid")
        .Sortable()
        .Editable(x => x.Mode(GridEditMode.PopUp).TemplateName("TITLEPATTERNEditor").Window(w => w.Width(700)))
        .Scrollable()
        .Filterable()
        .Resizable(r => r.Columns(true))
        .ToolBar(tools => tools.Excel().IconClass("k-icon k-i-download"))
        .Excel(excel => excel
        .FileName("TitlePatterns.xlsx")
        .Filterable(true)
        .AllPages(true)
        .ProxyURL("TitlePattern?handler=Save")
        )
          .Columns(columns => columns.LoadSettings(Model.columns)
   )
        .DataSource(ds => ds.Ajax().Events(events => events.Error("error_handler"))
        .Events(events => events.Error("error_handler"))
        .Read(r => r.Url(Url.Action() + "?handler=Read").Data("forgeryToken"))
        .Update(u => u.Url(Url.Action() + "?handler=UpdatePopUp").Data("forgeryToken"))
        .Destroy(d => d.Url(Url.Action() + "?handler=Destroy").Data("forgeryToken"))
        .Model(m =>
        {
            m.Id(id => id.Id);
            m.Field(p => p.Id).Editable(false);

        })
        .PageSize(50)
        )
        .Pageable()

          )

In the GridColumnSettings

 new GridCommandColumnSettings
            {
                Commands =
                {
                     new GridEditActionCommand()
                     {  
                         Name = "Update",
                         Text = "Update",
                         UpdateText = "Save",                         
                         CancelText = "Cancel"                         
                     },

                 },
                Width = "100px",
                Filterable = false,
                Locked = true,
                Title = "Update"
               },

And this is the template:

I am opening a window to display a razor page using the following

function dblClickCalEvent(e) {

		var win = $("#scheduleWindow").data("kendoWindow");

		win.refresh({
			url: "@Url.Page("ScheduleForm", "Details")",
			data: { clickDate: e.dataset.clickdate, scheduleId: e.dataset.scheduleid }
		});
		win.center().open();

	}

This opens the Razor page and calls the OnGetDetails and renders the page using the correct Model.  I have a MultiSelect on the page using the Select Event which once a value is selected POSTs back to the page using the following:

	function attendee_selected(e) {


		$.ajax({
			type: "POST",
			url: "ScheduleForm?handler=AttendAdd",
			data: { __RequestVerificationToken: '@token', attendee: e.dataItem.UserPrincipleName }
		});


	}

Which posts to this:

public async Task<IActionResult> OnPostAttendAdd(string attendee)

And returns Page();

I can see that the model gets populated while debugging the Razor page, however the page never renders the new results on page.  I have tried to call a refresh on the window but this has no effect.  Here is and example of where the ViewDates change once the Page is returned from the Post method and the changes are not reflected in the page in the window:

<table style="width: 100%;">
				<tr>
					@foreach (var d in Model.ScheduleAssistaint.ViewDates)
					{

						<td class="border1" style="text-align:center;">
							@d.ToLongDateString()
						</td>

					}
				</tr>
			</table>

Is this something to do with the fact the page is inside a window?  If so is there a way to fix this?

Thanks

I'm using the Drawer TagHelper and when the page opens, I'd like the Drawer to start open if the user cookie is set to open and closed if the cookie is set to closed. I am doing this currently using javascript but it causes it to open every time you go to a new page. Is there a setting on the taghelper that will cause it to start out open or closed rather than having to set it using javascript?

Thanks!

Here's my code:

Howdy!

I have a scenario in which I have messages stored in a database. My client would like to enable a website portal for his employees to read/respond to said messages. (We already have this implemented and working in a WPF application using the RadChat control from the WPF library)

The documentation for the chat control in ASP.NET Core is really sparse. Like 3 pages of information and that's it. No examples on data binding like most other controls you have... So, my question is this: is it possible to bind the Messages that show up in the chat control similar to the way in which I can say, bind the data that shows up in the ASP.NET Core Grid using a data source transport mechanism?

I know in the case of the WPF implementation, I had to implement a converter for the messages in order to bind them to the control...

Hi,

I have a .net core submission form with an upload that works at the moment,  the form submits successfully, and the files are transferred to S3. Is it possible to convert this form to ajax submission and display the loader whilst the form and uploads are processing before I return my success message?

I have a similar problem to this old thread: Dealing with data which includes a field having an array of objects in Kendo UI for jQuery | Telerik Forums.

I linked a field that is an array of a specific class to a Kendo ListView of a custom editor when you create or edit a scheduler item.

When I add or remove items, there are no problems. Apparently, the scheduler recognizes that there are more or fewer items in the list, but when I modify a list item (one of its properties), the scheduler does not trigger the update event.

Is there a way to trigger the update event when the ListView items are modified or force it to fire?

Hello,

Our company uses Telerik developing web application. I am working on CI/CD, and I found Telerik NuGet source is good - except it requires clear text password.

It's nice to have the NuGet source support API key authentication, and key management in the account generated the key.

In this way we can avoid the risk to publish clear text password. 

Please consider support it :)

Thanks.
