Hello
How can I content Script 

.ClientTemplate

transfer it to file or Partial, that is, to have a code similar to the following:

columns.Bound(e => e.TicketId).Title(" ").ClientTemplate("
 @await Html.PartialAsync("_MsgList_FileUpload_Select",new { MessageId = "#=MessageId#" })
")

Good afternoon,

I've noticed an inconsistency with the styles of textboxes when editing inline in a grid for textboxes and numeric textboxes.

In the demo they appear correctly, having had the surrounding span added, and have the theme's colouring and styling:

https://demos.telerik.com/aspnet-core/grid/editing-inline?autoRun=true&theme=classic-opal

However, if you edit in Telerik REPL (and the same happens for me in my dev environment) the numeric textboxes display differently, and don't pick up the theme's styling:

I've also notice that the EditorTemplates for Boolean, Date and DateTime are not working correctly as the closing bracket appears too early and renders the text:

HtmlAttributes(new { title = Html.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldName("")})

I have fixed this by editing the templates.

Kind regards,

Richard

Hi,

I have a Kendo Validator with some custom rules, including hitting an API to prevent name duplication.

            rules: {
                noDups: function (input: any) {
                    if (input[0].id == "Name") {

                        let url = $("#duplicate-link").data("url") + "?name=" + input.val();

                        $.get(url, function (response) {
                            return !response;
                        });
                    }

                    return true;
                },

Basically, if the name comes back as "already found" from the API, return false.

I have logged the output and the response is returning false when the name matches.

However, when validating the form, only the required validator is firing.  I don't see the false return value affecting the validator's red box and validation message, and the form still submits.

        $("#submit").on("click", function () {
            let validator = $("#form1").data("kendoValidator");

            if (validator.validate()) {
                console.log('validated');
            }
        });

                @(Html.Kendo().TextBoxFor(m => m.Name).HtmlAttributes(new { @class = "form-control", placeholder = "Application Name", required = true, data_noDups_msg = "This field is required" }))

Any thoughts?  Thanks!

The model I have to work with has mixed Json property names. Can´t easiely unify them as that will break filtering on the db. While the grid has a seperate model from the db entity ToDataSourceResultAsync is called after mapping the IQueryable, so cosmosdb will use the json attributes on the grid model and not the db entity to generate the query. Prior to .net core there supposedly was a method to define the field name .From.

.Model(model =>
{
   model.Field(p => p.Name).From("name");
})

The .From method no longer seems to exist. My workaround for now was to implement a custom extension method that uses reflection to set the name.

public static class KendoExtensions
{
    public static DataSourceModelFieldDescriptorBuilderBase<T, TDataSourceModelFieldDescriptorBuilder> MapFrom<T, TDataSourceModelFieldDescriptorBuilder>(
        this DataSourceModelFieldDescriptorBuilderBase<T, TDataSourceModelFieldDescriptorBuilder> builder, string name)
        where TDataSourceModelFieldDescriptorBuilder : DataSourceModelFieldDescriptorBuilderBase<T, TDataSourceModelFieldDescriptorBuilder>
    {
        var fieldInfo = builder.GetType()
            .GetField("descriptor", BindingFlags.Instance | BindingFlags.NonPublic);

        var descriptor = (ModelFieldDescriptor)fieldInfo!.GetValue(builder);

        descriptor!.From = name;
        return builder;
    }
}

Is there another way of doing this now? The above works just fine right now, but accessing protected members of 3rd party libraries is something I would very much like to avoid.

The following is the link where they said that there is supposed to be a .From method, but that does not seem to exist for me in 2023.1.117.

Only just now saw that the last reply said that this is only available when using a Custom Data Source. Guess I gotta do that instead then. Will try that tomorrow. Not sure why that would be required looks like a case of more boilerplate for no reason to me.

Hi, 

I'm working on develop web application using MVC Core with Razor. I'm using kendo upload to upload excel file.  After I got the uploaded excel file, I want to read the data to the temp table (or grid if possible). How do I get to the Posted File InputSteam to read  or loop data to temp table? With asp.net web form, I used PostedFile.InputSteam to read data, how do I do that with kendo upload control?

Thank you for your help.

Hello,

I want the grid to be refreshed column wise as the DataTable datasource changes. Calling the client side read function refreshes the data source but does not refresh the columns based on the data source changing. We have filters that will remove/add columns since the DataTable is dynamic. I am populting the grid like below:

ASP.NET Core Dynamic Grid in ASP.NET Core - Telerik UI for ASP.NET Core

Thank you.

A new demo application called e-shop was released concomitant with the release of Telerik UI for ASP.NET Core 2023.1.117.    Normally source code for demo programs can be installed as an option in the Control Panel.  However, in this case,  it appears, after some searching that the course code  was not installed in the C:\Program Files (x86)\Progress\Telerik UI for ASP.NET Core R1 2023\wrappers\aspnetcore\Examples folder.   Runnning the Demo Shortcut and clicking on the sample e-shop Applcation simply takes you to https://demos.telerik.com/aspnet-core/eshop/. 

Can anyone point me to a download link for the source files for the e-shop sample application?

I'm trying to use the pdf Viewer control to display pdfs which have fillable forms on them.  When I open the pdf with viewer control the fillable pdfs just show up as a flat pdf (meaning the form fields are not fillable).  Is there a way to get the PdfViewer control to display the pdf as a fillable pdf?  I feel like with tools like RadPdf, this has got to be possible in the browser and would be surprised if there wasn't a way to do this with our Kendo controls.

Ultimately, I want to submit that filled in pdf back to the server to be saved back to the database.
