We need your feedback, because we are considering changes in the release approach for Telerik UI for ASP.NET MVC. Please provide your feedback in the comments section below:


1. Is it hard to understand the version numbers of our releases? If yes, what makes them hard to understand them?

2. Would semantic versioning (SemVer) of our releases make it easier to understand our version numbers and what's behind them?

3. If we go with SemVer, we might need to start with version 3000.0.0 as we currently use 2022.x.x. Please share your thoughts about this approach and ideas for what number versioning would work best for you.

 am using Azure Ad authentication in my ASP.Net 4.8 MVC application. When authentication is expired and when user clicks on the link or button user get redirected to login page. So that is good.

However, I have a problem with AutoComplete textbox which is also available on the same page among buttons and link. If user leave the app open and comes back after page authentication cookie is expired and enter a value in autocomplete textbox, then textbox doesn't do anything, it works as there is no data to filter and doesn't even throw an error. I would expect it to redirect user to login page or refresh the token.

I suppose that could be known to those who uses Jquery or ajax functions or telerik controls to how to check for token. I am just new to all that.

Just in case if the code is needed so here it is.

  <form action="@Url.Action("Transaction", "Job")" method="POST">
            <div>
                <div class="col-xs-4 k-content py text-left">

                    @{
                        try
                        {
                            @(Html.Kendo().AutoComplete()
                    .Name("searchValue")  //chaninging the name of the class to UserModel
                    .DataTextField("SearchString") //DataTextField("dataField")
                    .Filter("contains")
                    .MinLength(2)

                    .HtmlAttributes(new {style = "width:100%"})
                    .DataSource(source =>
                    {
                        source.Read(read =>
                        {

                            read.Action("GetAutoComplete", "Job")
                                .Data("onAdditionalData");
                        })
                            .ServerFiltering(true);
                    })
                    //.Events(e => e.DataBound("onDataBound"))
                    )

                        }
                        catch (Exception e)
                        {
                            //this.RedirectToAction("Reporting", "ReportManagement");
                        }

                    }

I'm trying to reduce the clutter on the grid column headers. I love the idea of giving the users the power to hide and show columns but do not want to see those 3 dots on every column. For all other columns i just want the filter icon present.

I want to show the column menu only for the first column (first column is a selector checkbox). Version would be the latest and greatest. Is this possible?

I've tried a multitude of options, but the ones that don't throw errors, I get "/Date(16400...." as the results

Here are some of the tries.

columns.Add().Field("StartDate").Title("Start Date").Template("#:kendo.toString(StartDate,'MM/dd/yyyy')#").Width("150px");

columns.Add().Field("StartDate").Title("Start Date").Template("#:data.StartDate.ToString('MM/dd/yyyy')#").Width("150px");

columns.Add().Field("StartDate").Title("Start Date").Template("#= kendo.toString(StartDate, 'MM/dd/yyyy')#").Width("150px");

 

I did see the one user voice asking for a "Format" method for MCCB as getting the escape correct is difficult but didn't give any examples.

Hello everyone,

I have a little problem with editing my grid and I hope you can help me.

I am currently developing a grid (Telerik UI for ASP.NET MVC Grid) in which you can open another grid using a button at the end of the row. In this second grid it is possible to select one or more employees (Inline Editing with a DropDown) for the previous entry. In addition to the actual employee, there is another column where you can set a checkbox to "true" or "false". You can create a new entry with the button on the top left and you can edit or delete it with the two buttons on the right in the line.

Now to my question: My plan is that the name of the employee can only be changed when creating the entry. If you click on Edit, the name should no longer be editable, only the checkbox should be.

How exactly do I do this?

I had the idea to set the field "UserId" to .Editable(false) under .Model. But if I do that, I can neither change the value when creating nor when editing. When creating the entry, the drop-down menu for selecting an employee should be available, but not when editing.

In the attachments I have pictures showing the grid exactly.

Thanks in advance
Lars

 

@(Html.Kendo().Grid(Model)
    .Name("AssignmentsGrid")
    .Columns(c =>
    {
        c.ForeignKey(m => m.UserId, (IEnumerable) ViewData["users"], "Id", "Name").EditorTemplateName("ProjectUserDropdown");
        c.Bound(m => m.Resigned).ClientTemplate("<input type='checkbox' #= Resigned ? checked='checked' :'' # disabled='disabled' />");

Greetings,

 

I'm working on an issue with our Kendo UI...essentially i have a parent node and i want to add a child node and have the change show up immediately like it does in the Kendo UI example.  Upon clicking Add for a new child node, i can enter my details and update the row. 

In the example shown here: https://demos.telerik.com/aspnet-mvc/treelist/editing you'll see once the update button is clicked the row automatically updates and you can see the child node you've created.

My issue is that once i click the update button the row disappears and only a page refresh will show the new child node row.

The error i get when trying to update the row is a generic: POST http://localhost:16922/Rackhouses/RackhouseTreeList_Add 500 (Internal Server Error)

Here's my cshtml for the treelist:


@(Html.Kendo().TreeList<WhiskeySystems.ViewModels.RackhouseTreeListItemVM>
    ()
    .Name("treelist")
    .Toolbar(toolbar => toolbar.Create().Text("Add Rackhouse"))
    .Columns(columns =>
    {
        columns.Add().Field(e => e.Name).Title("Name").Width(220);
        columns.Add().Field(e => e.InMyBond).Title("In My Bond").Width(100).Template("<input type='checkbox' data-bind='checked: InMyBond' onclick='return false;'/>" );
        columns.Add().Field(e=> e.Tiers).Title("Tiers");
        columns.Add().Field(e => e.Rows).Title("Rows");
        columns.Add().Field(e => e.Capacity).Title("Capacity");
        columns.Add().Width(300).Command(c =>
        {
            c.Edit();
            c.Destroy();
            c.CreateChild().Text("Add Zone");
            c.Custom().Name("defaultZone").ClassName("zoneDefault").Click("setDefaultZone").Text("Set Default");
        });
    })
    .Editable(e=>e.Mode("inline"))
    .DataSource(dataSource => dataSource
    .Create(create => create.Action("RackhouseTreeList_Add", "Rackhouses"))
    .Read(read => read.Action("RackhouseTreeList_Read", "Rackhouses"))
    .Update(update => update.Action("RackhouseTreeList_Update", "Rackhouses"))
    .Destroy(delete => delete.Action("RackhouseTreeList_Delete", "Rackhouses"))
    .Events(e=> { e.Error("onError"); e.RequestEnd("requestEnd"); })
    .Model(m => {
        m.Id(f => f.Id);
        m.ParentId(f => f.ParentId);
        m.Expanded(true);
        m.Field(f => f.Capacity);
        m.Field(f => f.DistilleryId);
        m.Field(f => f.InMyBond);
        m.Field(f => f.InvTypeId);
        m.Field(f => f.Name);
        m.Field(f => f.Rows);
        m.Field(f => f.Tiers);
    })

    )
    .Events(e => { e.DataBound("OnDataBound"); e.Edit("OnEdit"); })

    )


Heres my TreeList Add code for the controller:

 


public JsonResult RTreeList_Add([DataSourceRequest] DataSourceRequest request, RTreeListItemVM VM)
        {
            using (var contextScope = _scope.Create())
            {
                try
                {

                    _RBS.AddRTreeListItemVM(VM);
                    contextScope.SaveChanges();
                    //Assign the new Id back to the VM after saving.
                    if (VM.ParentId.HasValue)
                    {
                        VM.Id = VM._zone.Id + 0.2m;
                    }
                    else
                    {
                        VM.Id = VM._r.Id + 0.1m;
                    }
                }
                catch (Exception ex)
                {
                    ModelState.AddModelError("Error", ex.Message);
                }

                return Json(new[] { VM }.ToTreeDataSourceResult(request, ModelState), JsonRequestBehavior.AllowGet);
            }
        }









                   

 

 

I've done quite a bit of troubleshooting and cant seem to find anything that stands out.  Made sure my scripts are running in the right order.  Im new to kendo so still trying to ramp up my knowledge here.  Thanks in advance!

Hi,

In the export to Excel from Kendo grid have problem.

Can I put one field as textual, one as a date and all others as a number? When exporting, they all come to me as numbers, so I have a problem with XLSX that eats the first 0, and I would like to put that field in textual.

This is my code:

 SpreadDocumentFormat exportFormat = SpreadDocumentFormat.Xlsx;

            Action<ExportCellStyle> cellStyle = new Action<ExportCellStyle>(ChangeCellStyle);
            Action<ExportRowStyle> rowStyle = new Action<ExportRowStyle>(ChangeRowStyle);
            Action<ExportColumnStyle> columnStyle = new Action<ExportColumnStyle>(ChangeColumnStyle);
            List<ExportColumnSettings> columnsData = new List<ExportColumnSettings>();
            //columnsData.Add(new ExportColumnSettings() { Field = "RB", Title = "R.b.", Hidden = false, Format = null });
            columnsData.Add(new ExportColumnSettings() { Field = "BR", Title = "BR", Hidden = false, Format = null });
            columnsData.Add(new ExportColumnSettings() { Field = "Date", Title = "Date", Format = "{0:MM/dd/yyyy}", Hidden = false });
            columnsData.Add(new ExportColumnSettings() { Field = "Name", Title = "Naziv i sjedište", Format = null, Hidden = false });
            columnsData.Add(new ExportColumnSettings() { Field = "OIB", Title = "OIB", Format = "@", Hidden = false });
            columnsData.Add(new ExportColumnSettings() { Field = "Iznos", Title = "Iznos rn.", Format = null, Hidden = false });

 

and my settings for Cell style:

   private void ChangeCellStyle(ExportCellStyle e)
        {
            bool isHeader = e.Row == 0;
            SpreadBorder border = new SpreadBorder(SpreadBorderStyle.Thin, new SpreadThemableColor(new SpreadColor(0, 0, 0)));

            SpreadCellFormat format = new SpreadCellFormat
            {
                ForeColor = isHeader ? SpreadThemableColor.FromRgb(50, 54, 58) : SpreadThemableColor.FromRgb(0, 0, 0),
                VerticalAlignment = SpreadVerticalAlignment.Center,
                    //NumberFormat = "dd.MM.yyyy.", 
                    //NumberFormat = "@",
                TopBorder = border,
                BottomBorder = border,
          
            };
            e.Cell.SetFormat(format);
        }

 

Thnx,

Andrea
