In our UI for ASP.NET Core R3 2020 (2020.3.915) release, the Column menu message of unsticking a column is "null".

This bug will be resolved in our next official release.

In the meantime, as a workaround, manually set the Unstick Column menu message:

.ColumnMenu(c => c.Messages(m => m.Unstick("Unstick Column")))

I have a grid whose first column is a string column, and the 2nd and 3rd columns are sometimes dropdowns based on the value shown in the first column.

I have it mostly working except for a small issue. If I click slowly enough it seems to work but if i click around the different cells eventually my dropdown appears in a cell that it should not. What is the correct way to implement the described behavior?

Should I be looking for a cell template solution? Or do I need to subscribe to a custom grid event?

Any advice would be much appreciated.

Below code needs to be corrected for ASP.NET Core Grid Popup Editing : 

https://demos.telerik.com/aspnet-core/grid/editing-popup?autoRun=true&theme=default-main-dark

.DataSource(dataSource => dataSource .Ajax() .PageSize(20) .Events(events => events.Error("error_handler")) .Model(model => model.Id(p => p.ProductID)) .Create(update => update.Action("EditingPopup_Create", "Grid")) .Read(read => read.Action("EditingPopup_Read", "Grid")) .Update(update => update.Action("EditingPopup_Update", "Grid")) .Destroy(update => update.Action("EditingPopup_Destroy", "Grid"))

 

It seems create arrow function is called for update & destroy as well.

while editing the row data EditingPopup_Create create is called instead of update !!

Hello ,

We use the method ToDataSourceResult ( Telerik UI  for Asp.net Core 2024.1) and EF Core (8.0) to perform a simple query on a table. The primary key of the table is a String type and is case-sensitive. There are two pieces of data in our database. Their primary key values only differ in case.

ID: DEHE061800005DTF, Name: First

ID: DEHE061800005DTf, Name: Second

When we filter based on the primary key, we always get two pieces of data, but they are actually the same piece of data. In other words, another piece of data was not returned. Such as:

ID: DEHE061800005DTF, Name: First

ID: DEHE061800005DTF, Name: First

It seems that some kind of operation is performed internally according to the primary key, but because the case is not taken into account, the same piece of data is used twice.

We wanted to know if we could somehow solve this problem.

Thanks!

How can I solve the Enum filter uing same code but without using ItemTemplate or UI()

/View
columns.Bound(c => c.EmpTypes).Title("Type")
.Filterable(filterable => filterable
.Multi(true)
.ItemTemplate("typetemplate")
.DataSource(ds => ds.Read(r => r.Action("GetEmpTypes", "Report"))));

<script>
    function typetemplate(e) {
        return ({ Text, Value }) => `<span><label><span>${Text}</span><input type='checkbox' name='" + e.field + "' value='${Value}'/></label></span><br/>`
    }
</script>

//ReportController.cs
public JsonResult GetEmpTypes()
{
    var enumList = EnumToSelectList(typeof(EmpTypes)); // Convert the Enums to List<SelectListItem>
    return Json(enumList, JsonRequestBehavior.AllowGet);
}

public static List<SelectListItem> EnumToSelectList(Type enumType)
{
     return Enum
              .GetValues(enumType)
              .Cast<int>()
              .Select(i => new SelectListItem
              {
                  Value = i.ToString(),
                  Text = Enum.GetName(enumType, i),
              })
              .ToList();
}

I'm upgrading to Kendo 2024.1.130 and I've been able to get svg icons on a button or other places using this construct.

<div class="ara-footer">
    <button class="k-button k-button-icontext" onclick="cancelEdit(id)">
        <span id="ericIcon"></span>
        Back
    </button>
</div>
<script>
    kendo.ui.icon($("#ericIcon"), { icon: 'camera' });
</script>

That worked flawlessly.  Thank you for the great example.

Now I'm trying to add svg icons to a Custom command in a grid.  This is the code I have previously when using font-icons.

Html.Kendo()
.Grid<TemplateModel>()
.Name("GridApprovedTemplates")
.Columns(columns =>
{

columns.Command(command => { command.Edit().Text(" ").UpdateText(" ").CancelText(" "); command.Custom(" ").Text("<span class='k-icon k-i-info'></span> ").Click("refreshApprovedTemplateDetail"); }).Width(150);

The code that worked for a single button doesn't work here because you can't have the same id on multiple places in the DOM.  How would I go about using an svg icon here?  (Let's use the camera one as an example).

Telerik UI for asp.net core 2024.1.130

I am trying to implement a grid popup with dropdown list in asp.net core (tag helper) , would like to know how to make this work.

List associated with dropdownlist will be available via a web api call.

please use the following sample as a starter, where we have popup with Frieght, order date, shipName, shipCity 

https://netcorerepl.telerik.com/QoYdOJlL07aiiORy37

I would like to convert shipCity from text box to dropdown list, where i get the list of cities using a web api call.

Could you please help me with this implementation? (if there is already another sample which demonstrates this, that would be fine as well)

Hi There,

I have a complex model in view.  But, i sended simple example for subject.

 

Main View Model : 

public class ErpProductModel
{
    public string Title { get; set; }
    public string Code { get; set; }
    public string ShortCode { get; set; }
    public int MinStock { get; set; }
    public int ShelfLife { get; set; }
    public int CategoryId { get; set; }
    public int TaxCategoryId { get; set; }
    public decimal AmountInProduct { get; set; }
    public int MeasureWeightId { get; set; }
    public int CountryId { get; set; }
    public int StatusId { get; set; }
    public List<ErpProductPackageTypeModel>? PackageTypes { get; set; } = [];
}

PackageTypes Model : 

public record ErpProductPackageTypeModel 
{
    public int? ProductId { get; set; }
    public string Barcode { get; set; }
    public int Quantity { get; set; }
    public string? PackageType { get; set; }
    public int PackageTypeId { get; set; }

    public List<SelectListItem> AvailablePackageTypes { get; set; } = [];
}

View Source :


<script type="text/x-kendo-tmpl" id="packageTypeTemplate">
         <div class="card widget widget-info">
             <div class="card-body">
                 <div class="widget-info-container">
                     <div class="widget-info-image" style="background: url('@Url.Content("/Assets/Images/barcode_mock.png")')"></div>
                     <h5 class="widget-info-title">#=Barcode#</h5>
                     <p class="widget-info-text">#=PackageType# / #=Quantity# PCS</p>
                 </div>
             </div>
         </div>
</script>

@(Html.Kendo().ListView<ErpProductPackageTypeModel>()
            .Name("package-types")
            .BindTo((IEnumerable<ErpProductPackageTypeModel>)Model.PackageTypes)
            .TagName("div")
            .Bordered(false)
            .Layout("grid")
            .Grid(p=> p.Cols(4).Gutter(20))
            .ClientTemplateId("packageTypeTemplate")
            .HtmlAttributes(new { @class= "rubi-listview package-types" })
            .DataSource(dataSource => 
                dataSource.Ajax()
                .Batch(true)
                .ServerOperation(false))
            )

 

Controller Post Method :


[HttpPost]
public virtual async Task<IActionResult> EditAsync(ErpProductModel model)
{
    var erpProduct = await _erpProductService.GetErpProductAsync(model.Id);
    if (erpProduct == null)
        return RedirectToAction("List");
    erpProduct = model.ToEntity(erpProduct);

    await _erpProductService.UpdateErpProductAsync(erpProduct);

    return RedirectToAction("Edit", new { id = erpProduct.Id });
}
When the page is first opened, data is filled into the listview control. No problem here. But when I do a post operation again, the PackageTypes in the model are not filled. In fact, it does not even appear in the first data that arrives. I couldn't figure out why. I only want a Client Side transaction.

My scenario is simple;
I have a product save screen. There are package types depending on this product. If all I want is to fill the package types, I will make various updates, additions or deletions on this data.

Thank you in advance for your help.

Hello,

I am surprised this is not asked about more in the forums on using JavaScript functions in view components.

I have a grid inside a view component and am having issues getting the datasource read Data function to work so I can pass parameters from the view component's backend .cs file to my API (it says grid_getReadParameters is undefiend even though it's defined in script tag at the bottom of the view component). I have read that view components can't really have javascript or something strange like that which makes no sense. I defined a script section in my view component and it was unable to find "grid_getReadParameters". How does one define this within the view component? I do not want to have to sprinkle this around on every page which uses my view component, that would defeat the purpose. Thanks in advance for your help.

See below example:

@(Html.Kendo()
    .Grid<ViewModels.MyViewModel>()
    .Name("grid_" + uniqueId)
    .Sortable()
    .Editable(editable => editable.Mode(GridEditMode.InCell))
    .Filterable()
    .ToolBar(x =>
    {
        x.Create().Text("Add New");
        x.Save().SaveText("Save").CancelText("Cancel");
    })
    .Columns(columns =>
    {
        columns.Bound(c => c.Value)
        .Width(125)
        .Filterable(ftb => ftb.Multi(true).Search(true).CheckAll(true));
    })
    .DataSource(ds => ds
            .Ajax()
            .Batch(true)
            .ServerOperation(false)
            .Read(r => r.Url("/api/ControllerName?handler=MethodName").Data("grid_getReadParameters"))
            .Events(events => events.Error("grid_error"))
            .PageSize(100)
            .Model(m =>
            {
                m.Field(id => id.Value).Editable(true);
            })
    )
)

In the Grid for ASP.NET AJAX, it was possible to drag an entire row (see Telerik Web Forms Drag and Drop of Grid Items - RadGrid - Telerik UI for ASP.NET AJAX and Telerik Web UI Grid Items Drag-and-drop Demo | Telerik UI for ASP.NET AJAX).

In the Grid for ASP.NET Core however, it appears to be necessary to use a "drag handle" in a specific column to drag the row which some of my users are finding somewhat "clunky" and even I find difficult on occasion as I sometimes find that instead of dragging I am in fact highlighting page content instead.

Is it possible to drag an entire row in Grid for ASP.NET Core instead of having to use the drag handle?

In particular, I am looking to be able to drag between grids as well as being able to drag within grids.

Thanks.
