[Solved] How to disable a grid button after successful post

I have an ajax post method where the user will sign up for an open slot. After the slot gets assigned, I want to disable the button and change the text. Can anyone tell me what I'm doing wrong here. I'm coming from Web Forms to MVC so it's been a little learning curve.

here's my grid

@(Html.Kendo().Grid(Model)
                .Name("Grid")
                .Columns(columns =>
                {
                    columns.Bound(p => p.Id).Hidden(true);
                    columns.Bound(p => p.JobStartDateTime).Visible(false);
                    columns.Bound(p => p.JobInfo).Title("Job");
                    columns.Bound(p => p.JobTimes).Title("Times");
                    columns.Bound(p => p.JobPayDisplay).Title("Pay");
                    columns.Command(cmd => cmd.Custom("Details").Click("Details"));
                    columns.Command(cmd => cmd.Custom("Sign Up").Click("SignUp"));


                })
                .Pageable()
                .Scrollable(scr => scr.Height(500))
                        .DataSource(dataSource => dataSource
                            .Ajax()
                            .PageSize(20)
                            .ServerOperation(false)
                        )
                )

and then here's the javascript function

function SignUp(e) {
        var id = $(e.currentTarget).closest("tr").find('td:first').html();
        $.ajax({
            type: 'POST',
            url: '/Jobs/SignUp',
            data: {id : id},
            headers: { "RequestVerificationToken": $('input[name="__RequestVerificationToken"]').val() },
            contentType: 'application/x-www-form-urlencoded; charset=UTF-8', 
            success: function (result) {
                alert(result);
                $(this).find(".k-grid-SignUp").addClass("k-state-disabled");
                $(this).find(".k-grid-SignUp").text("Awarded");
            },
            error: function () {
                alert('Failed  ' + result);
                
            }
        })
    }

How to filter a grid column from a ComboBox selected value

I have a combobox separate from my grid and I want to use the comboBox selected value to filter the grid results. Do I need to do this in Java script? What is the best way to do this?

Upgrade to Nuget package Telerik.UI.for.AspNet.Core 2022.2.510 now requires nuget package Microsoft.AspNetCore.Mvc.NewtonsoftJson

In Core 6 project setting following global JSON option to maintain property case (such as required for returning JSON result for Kendo Grids), since the Telerik upgrade, you now have to manually add Microsoft.AspNetCore.Mvc.NewtonsoftJson nuget package

builder.Services.AddRazorPages().AddNewtonsoftJson(options => options.SerializerSettings.ContractResolver = new DefaultContractResolver());

or change to use System.Text.Json

builder.Services.AddRazorPages().AddJsonOptions(options => options.JsonSerializerOptions.PropertyNamingPolicy = null);

TabStrip reload undefined

Hello,

I am trying to reload the content of one of my Tabs in different scenarios. I have different grids and other tabs that when their content changes I need to reload my checklist tab. However, when I call tabStrip.reload("li:first"); I get reload undefined.

Here is my TabStrip:

                  @(
                        Html.Kendo().TabStrip()
                        .Name("CaseTabStrip")
                        .TabPosition(TabStripTabPosition.Left)
                        .Animation(animation => animation.Open(effect => effect.Fade(FadeDirection.In).Duration(5)))
                        .Events(events => events.ContentLoad("onContentLoad"))
                        .Items(items =>
                        {
                            items.Add().Text("Checklist")
                                .Selected(true)
                                .LoadContentFrom(Url.Action("Checklist", "Cases", new { caseId = Model.Id }));
                           
// Extra tabs removed for brevity

                            items.Add().Text("Documents")
                                .LoadContentFrom(Url.Action("Index", "Documents", new { caseId = Model.Id }));
                        })
                        .HtmlAttributes(new { @class = "mt-5" })
                    )

And, this is how I am implementing the reload of the Checklist tab.

        var ReloadChecklist = () => {
            var tabStrip = $("#CaseTabStrip").data("kendoTabStrip");
            tabStrip.reload("li:first"); // No console error, but stepping through code shows "reload undefined"
        }

        function DocTypeRequestEnd(e) {
            var grid = $("#Documents").data("kendoGrid");
            if (grid) {
                grid.dataSource.read();
            }
            ReloadChecklist();
            GridRequestEnd(e);
        }

Where I call tabStrip.reload() I don't get a console error but the debugger show "reload undefined." It's odd because I can inspect the tabStrip variable and see my items. I can also see reload as an option under <prototype>

[Solved] How to change the mouse point of the dropdown content in ASP.NET Core Kendo MultiColumnComboBox

Hi,

I'm struggling to change the mouse pointer when selecting a value inside MultiColumnComboBox. Before opening, the mouse pointer looks correct, but then it opens and the cursor attribute doesn't seem to apply.

I tried .HtmlAttributes(new { style = "cursor:pointer;"})

Thoughts or ideas?

Thanks,

Grid column Select() to bool model property

Hello I use in my form grid where I want to have checkbox selection.

I'm still lost how to bind selected row to model property "bool PrintOP"

Here is my .cshtml

div class="table-responsive">
                @(Html.Kendo().Grid(Model.ProdOrderLines)
                .Name("#grid")
                .Editable(editable => {
                    editable.Mode(GridEditMode.InCell);
                })
                .DataSource(dataSource => dataSource
                .Ajax()
                .Batch(true)
                .Model(m =>{
                    m.Id(id=>id.ProdOrderLineId);
                    m.Field(id=>id.PrintOP);
                    m.Field(id=>id.OperationNumber).Editable(false);
                    m.Field(id=>id.OperationName).Editable(false);
                    m.Field(id=>id.Machine).Editable(false);
                    m.Field(id=>id.Recipe1).Editable(false);
                    m.Field(id=>id.Recipe1C).Editable(false);
                    m.Field(id=>id.Recipe2).Editable(false);
                    m.Field(id=>id.Recipe2C).Editable(false);
                    m.Field(id=>id.Recipe3).Editable(false);
                    m.Field(id=>id.Recipe3C).Editable(false);
                    
                }))
                .Columns(c=>{
                    c.Bound(c=>c.ProdOrderLineId).Hidden(true)
                        .ClientTemplate("#= ProdOrderLineId # <input type='hidden' name='ProdOrderLines[#=index(data)#].ProdOrderLineId' value='#= ProdOrderLineId #' />");
                    c.Select().Width(50);
                    c.Bound(c=>c.OperationNumber).Width(50);
                    c.Bound(c=>c.OperationName).Width(100);
                    c.Bound(c=>c.Machine).Width(100);   
                    c.Bound(c=>c.Recipe1).Width(100);
                    c.Bound(c=>c.Recipe1C).Width(100);
                    c.Bound(c=>c.Recipe2).Width(100);
                    c.Bound(c=>c.Recipe2C).Width(100);
                    c.Bound(c=>c.Recipe3).Width(100);
                    c.Bound(c=>c.Recipe3C).Width(100);
                })
                .Editable(ed => ed.Mode(GridEditMode.InCell)))
              <br />
              <br />
            </div>

What I would like to have is when user select row change model property "PrintOP" to true or false for corresponding ProductLine[x]

I hope there is some solution?

Here is also model used in Form

public classOrderDetailViewModel
    {
        public string OrderID { get; set; }    
        public string  ProductName { get; set; }
        public float OrderLength { get; set; }
        public int COL { get; set; }=0;      
        public float CalcLength { get; set; }=0;
        public float RemainingPaste { get; set; }=0;
        public List<ProdOrderLineViewModel> ProdOrderLines {get;set;}
    }

 public classProdOrderLineViewModel
    {
        public int ProdOrderLineId { get; set; }
        public int OperationNumber { get; set; }
        public string OperationName { get; set; }
        public string Machine { get; set; }
        public string Recipe1 { get; set; }="";
        public string Recipe1C { get; set; }="";
        public string Recipe2 { get; set; }
        public string Recipe2C { get; set; }
        public string Recipe3 { get; set; }
        public string Recipe3C { get; set; }

        public bool PrintOP { get; set; }=false;

    }

Many THX in advance for your help.

How to make a colum not resizable ?

Is there a way for ASP.NET Core grid to mark a column as NOT resizable? I mean, no way to resize that column, even if others are able to resize?

Please see this thread on SO.

The proposed solution should work does not matter is that column bound to a data or not, is the column last or first or not. Especially the case when the column is the last one and is a command column. Often such columns are of fixed length, cause buttons or commands are fixed. The actions column should not be moved or resized. However, if the column is pushed by others, the column could go out of the visible view.
