Model:

 public string TemplateId { get; set; } 
 public byte[] Template { get; set; }
 public string? Filter { get; set; }
 public DateTime ValidFrom { get; set; }

I have Implemented a Grid with a popup editor.

The Template field is used to store the file as Blob in the DB.

In the add row there should be a File upload and in the edit also need a file upload.

I have created a custom template for add row, but the file is not post back to controller.

How can we send the file and the form data in the request to controller?

I have

@(Html.Kendo().TreeView()
    .Name("treeviewAvail")

...and...

 @(Html.Kendo().ListBox()
      .Name("listboxAvail")

How can I 'have both of those so that I can drag/drop from either into another list box?  (It's not needed to go the other way.)

@(Html.Kendo().ListBox()
    .Name("listboxSelected")

I've seen this topic, but it does not handle what I need for TreeView too

The page has two cascades ComboBox .
With a blank page, everything works fine.
But when data is transferred to the page (for editing), then the second ComboBox  does not display and is blocked.
It turns out after loading the data in the first ! does not fit into filterCategory.
How to fix this nuance?

Hello,

I am using upload as an editor template inside grid. But the actual file selected is not being passed to the controller. The controller save method always shows 0 files. Am I missing something here?

Please find the code snippets below.

Grid:

@(Html.Kendo().Grid<DocumentViewEditModel>
    ().Name("Documents").Columns(c =>
    {
    c.Command(command => { command.Edit(); command.Destroy(); }).Width(220).Visible(@readOnlyForm);
    c.Bound(d => d.DocumentId).Hidden(true);
    c.Bound(d => d.ProjectId).Hidden(true);
    c.Bound(d => d.ScagdocumentId).Title("SCAG Document").Width(140);
    c.ForeignKey(d => d.DocumentCategoryId, (SelectList)ViewData["DocumentCategoryList"]).Title("Document Status *").Width(150);
    c.ForeignKey(d => d.NoticeTypeId, (SelectList)ViewData["NoticeTypeList"]).Title("Notice Type *").Width(220);
    c.ForeignKey(d => d.EirtypeId, (SelectList)ViewData["DocumentTypeList"]).Title("Document Type *").Width(250);
    c.Bound(d => d.DocumentDescription).Title("Project Description *").Width(350).HtmlAttributes(new { style = "white-space: pre-line;" });
    c.Bound(d => d.LogDate).Title("Date Received *").Format("{0: MM/dd/yyyy}").Width(170);
    c.Bound(d => d.DueDate).Title("Due Date for Comment").Format("{0: MM/dd/yyyy}").Width(180);
    c.Bound(d => d.DateModified).Title("Date Modified").Format("{0: MM/dd/yyyy}").Width(120);
    c.Bound(d => d.ModifiedBy).Title("Modified By").Width(130);
    c.Bound(d => d.DocumentUploadEditor).EditorTemplateName("DocumentUploadEditor").Title("Upload").ClientTemplate("#:Filename#").Width(150);
    c.Command(command => command.Custom("View").Click("navigateToOpen")).Width(190);
    })
    .DataSource(d => d
    .Ajax()
    .Events(events => events.Error("error_handler"))
    .Read(r => r.Action("GetDocuments", "Projects").Data("getAdditionalData"))
    .Update(u => u.Action("UpdateDocuments", "Projects"))
    .Destroy(x => x.Action("DeleteDocuments", "Projects"))
    .Create(c => c.Action("CreateDocuments", "Projects").Data("getAdditionalData"))
    .PageSize(10)
    .Model(m =>
    {
    m.Id(d => d.DocumentId);
    m.Field("DocumentCategoryId", typeof(int));
    m.Field("NoticeTypeId", typeof(int));
    m.Field("EirtypeId", typeof(int));
    m.Field(d => d.DocumentDescription);
    m.Field(d => d.LogDate);
    m.Field(d => d.DueDate);
    m.Field("ScagdocumentId", typeof(string)).Editable(false);
    m.Field(d => d.ModifiedBy).Editable(false);
    m.Field(d => d.DateModified).Editable(false);
    m.Field("ProjectId", typeof(int));
    })
    )
    .Pageable()
    .Sortable()
    .Scrollable(s => s.Virtual(GridVirtualizationMode.Columns).Height("auto"))
    .HtmlAttributes(new { style = "width:1420px" })
    .Editable(e => e.Mode(GridEditMode.InLine))
    .ToolBar(toolbar => { if (@readOnlyForm) { toolbar.Create(); } })
    )

Editor Template:

@(Html.Kendo().Upload()
        .Name("DocumentUploadEditor")
        .Async(a => a
            .Save("UploadNoticeObjects", "Projects")
            .AutoUpload(true)
        )

        .Events(e => e.Upload("onNoticeUpload")
                .Success("onSuccess"))

 )

Controller:

I am trying to do ServerPaging with this example from telerik:  https://github.com/telerik/ui-for-aspnet-core-examples/tree/master/grid/razor-pages-custom-datasource-date-editing/RazorPageGridTest/Pages/Customer

I have modified OnPostReadRecords by adding [DataSourceRequest] DataSourceRequest request

public JsonResult OnPostReadRecords([DataSourceRequest] DataSourceRequest request)

And I have added .ServerPaging(true) to the grid definition.

The resulting value of request is default and the page number is always '1'.

I am new to the telerik controls, so it's really like casting spells for me.

Hello,

When using HtmlHelper I can do something like this if I want to change the UpdateText and CancelText to blank: 

columns.Command(command => {
    command.Edit()
    .Text(" ")
    .UpdateText(" ")
    .CancelText(" ")
    .HtmlAttributes(new { title = "Edit" });

    command.Custom("Destroy")
    .Click("showDeleteConfirmation")
    .IconClass("k-icon k-i-trash")
    .Text(" ")
    .HtmlAttributes(new { title = "Delete" });
}).Width(75);

How do I accomplish the same thing with TagHelper? I tried checking to see if there's a canceltext or updatetext attribute but there is none. 

<column width="75" title="Commands">
    <commands>
        <column-command text=" " name="edit" title="Edit" ></column-command>                      
        <column-command text=" " name="cancel" title="Cancel" ></column-command>
    </commands>
</column>

Thank you.

Context: This is an ASP.NET Core 6 project using MVC controllers.  I have successfully gotten Grid widgets to work on another page which shares the same _Layout as the below page.  As a result, I think it's unlikely that my issue is related to how Kendo is installed in the project.

The Problem

I am attempting to add a searchable DropDownList to my project.  Though my ultimate goal is to use Virtualization to allow the search of a very large number of objects, I am unable to get the widget to function with a much small set of test data.  No matter how I attempt to configure the widget or change how I pass data back to it I get the same result:

I have confirmed via the Visual Studio debugger that my Json response contains the correct data and contains no values that are null or empty. 

My Code:

View

Note: SamAccountName is the field that should be displayed, used for text search, and selected as a value by the user.

Controller

Domain Model

As stated, the current code is much more simple than what I will eventually require, but I cannot even get this to work.  I have tried structuring the controller about a hundred different ways, and the only change is that sometimes I get an error saying a field can't be recognized.  Is this something to do with how I'm structuring my Json?  

I've been beating my head against this for almost 2 days now, I could really use some help.

How can I do color text hyperlink in Telerik ASP.NET Core Grid?
