"[Bind(Prefix = "models")] " in    https://demos.telerik.com/aspnet-core/grid/editing

I strictly followed the code in this page, but my save updates doesn't work.  

Hello,

I'm new to UI for Asp.net core. I met a problem here.

I have a table "authors" , contains all the author id [A,B,D,G,F]

and I have another table "books", it will be a Grid, showing book name, author name, when inline editing, user can update the author name for the book. when user input 'C', then notify him put a wrong author name. because our list is [A,B,D,G,F] has no C.

how to do this?   or how to put a check box list when inline editing a row in Grid?

I'm getting a 400 Error when I click on the toolbar button to export the grid contents to Excel.  The call to the ProxyURL method never happens.

Chrome Dev Tools shows the following.

POST https://localhost:44329/Admin/Companies?handler=Read 400

I suspect this is because the Anti-Forgery token is not getting passed to the read that the export function uses although it looks like the same read call that the grid uses successfully.  Any ideas on how I can resolve this?

Hi Experts,

    I am using kendo-validator to validate the input controls like (Textbox, Dropdown etc.)

The validation for empty field is working if i move one control to another control using Tab.

I needed that all validation for empty fields should triggered on form submit, not on Tab.

The sample code is below.

<div class="row">
    <div class="col-md-4">
        <form id="addfacility" asp-action="Add" kendo-validator="true">
            <div asp-validation-summary="ModelOnly" class="text-danger" style="width:900px;"></div>

            <div class="form-group" style="width:400px;">
                <label asp-for="Name" class="control-label"></label>
                <input asp-for="Name" class="form-control" maxlength="200" style="width:300px" />
                @*<span asp-validation-for="Name" class="text-danger" style="width:500px"></span>*@
            </div>
            <div class="form-group" style="width:400px;">
                <label asp-for="Address.Address1" class="control-label"></label>

Hi, 

I follow https://docs.telerik.com/aspnet-core/getting-started/getting-started this instruction to create a new asp.net core 2.1 mvc project to test Telerik UI for Asp.net Core version 2019.1.220

I installed client resource manually following https://docs.telerik.com/aspnet-core/getting-started/getting-started-copy-client-resources#manual-installation . But the browsers console showed kendo js errors. I was sure I followed the instructions correctly, I don't know why it didn't work. 

I zipped the codes and attached the download url in this thread:

https://celiawestus2.blob.core.windows.net/publics/test/WebApplication1.7z 

Could anyone help to solve this problem?

Does the drop down list tag helper have events?  I can't seem to find documentation anywhere on events.  I want to take action when selected or changed.

The examples in the link below only cover the HTML Helper.

Hi,

Hello,

Is there a way to open the toolbar's splitbutton popup to show the items when the splitbutton itself is clicked instead of the little arrow?

Thanks,

Shawn A.

toolbar.ClientTemplat(string) seems to override all previous toolbar items.

So:

.ToolBar(toolbar => {
                        toolbar.Create(); /*toolbar.Save();*/
                        toolbar.Custom().Text("export").IconClass("k-icon k-i-table").HtmlAttributes(new { onclick = "approval_grid_export()" });

                        toolbar.ClientTemplate("etc");

                    })

seems to destroy the toolbar.Create() and toolbar.Custom().

Is there way to just add the ClientTemplate()?

Hello,

Is there a way to position the items in a Kendo Toolbar so that some buttons are located on the left-side of the toolbar and some on the right side with empty space between?

Thanks,
