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);

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);
        }

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,

Sam

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.

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. 

Hi, I am new to kendo grid and over all telerik, I am having issues populating the data.  

please check the code below. This is the simplest form.  

//cshtml view

@using Kendo.Mvc
@using Kendo.Mvc.UI
@model IEnumerable<Database.Station>
@{
    ViewBag.Title = "Records";
//    foreach(var v in Model)
//    {
//      var i=  v.Componenet;
//    }
}

@ViewBag.heading
<hr />


<hr />



@if (Model.Any())
{
    <div>

          @(Html.Kendo().Grid(Model) 
    .Name("grid")
    .Columns(columns => {
        columns.Bound(p =>p.ATA).Width(100);
        columns.Bound(p => p.Componenet).Width(100);
        columns.Bound(p => p.Description).Width(140);
        columns.Bound(p => p.DiskNumber);
        columns.Bound(p => p.SoftwareNumber).Width(150);
    })

    .HtmlAttributes(new { style = "height:430px;" })
    .DataSource(dataSource => dataSource
        .Ajax()

        .Read(read => read.Action("Main", "Station"))
     )
)
    </div>
    }

//controller

  public IActionResult Main()
        {
            var stationList = new List<Station>();
            var station = new Station
            {
                ATA = "22",
                SoftwareNumber = "check",
                DiskNumber = "1234",
                Componenet = "AC",
                Description = "Description"
            };
            stationList.Add(station);

            var station2 = new Station
            {
                ATA = "29",
                SoftwareNumber = "check2",
                DiskNumber = "1235",
                Componenet = "Bike",
                Description = "Description"
            };
            stationList.Add(station2);
            return Json(stationList);

        }
    }

I also noticed following the instruction. it does not tell me to include any css or javascript or any javascript code in script section. so nothing of that natrure is included.  Below is the outcome of the nuget.  I have no css or other js file from kendo. 

And this is what i get

Hi,

I would like to know if there's a way of displaying files that are already uploaded in the upload widget.
To make my inquiry clear, I want the upload widget to act as a table of the upload files it has already uploaded. The current behavior only shows the files that are added in the document at the moment  of uploading. Once you navigate out of the page and back the upload files array gets emptied.

Thanks in advance for any response!

Our customers using the spreadsheet copy/paste values in the Spreadsheet (ASP. NET CORE)

Sometimes pasted decimal separator is ".", sometimes is the ",".

Is there a way to search and replace the pasted values from "," to ".", or, if not, to search and replace in Spreadsheet ?

Hello,

I am working on an application that the client has just added additional filter criteria beyond what grid filter provides.

I believe I might be able to do this using the example here Create Filter Widgets with Multiple Filter Criteria | Kendo UI Grid for jQuery | Kendo UI for jQuery (telerik.com) - maybe. I'm using ASP.Net Core 5 Razor pages so sometimes examples don't always work.

All of the fields (except for a couple that are date fields) are char or text type columns in the database.  The client wants to be able to use functions like "greater than", "in",  and "Is one of".  (I know greater than is not going to give them what they think) but the In condition or the Is One of condition they say are needed.

The filter now for 2 items is not enough.

For example, they need to filter for several POs at once - as you might do with a sql query SELECT * FROM tableaname WHERE fieldname in ('po1', 'po1', 'po3', 'po4') as an example.  none of the data is sequential so the need for "IN" or "IS ONE OF" filtering conditions.

Is this possible?

How would it be coded and handled on the backend?

Are the available filters documented somewhere here on the site?

Can we use wild cards in the filter value?  As when the search condition may vary inside the string and not with the start or end with characters?

thanks!

Hello all,

Could someone point me to an example or suggest the best approach for this? The application is asp.net core 5 using Razor.

I am using GridColumnSettings in my grid because there is one SQL table to populate many different pages & we change elements based on the context of use.

On one page, we've added a custom function to the filtering for one column so that we can provide a SQL "IN" condition.  This is working great. However for that one column, can someone suggest how to provide a custom filter menu so that we restrict what options are provided. (Users are going to be confused if they have options on the filter menu that do not work as they expected...)

I've tried a few examples found from searching this site but none seem to work.  Either I got it wrong (for possible) or  because of the columns.LoadSettings<Model.columns> from the server side, it doesn't execute any client side code on the .cshtml page.

I've included the relevant code below.

Any suggestions or examples will be greatly appreciated.  Thank you.

This is the grid on the .cshtml page.

<div id="griddiv">
    @(Html.Kendo().Grid<HPK_DATA>(Model.testdata)    
    .Name("grid")
    .Columns(columns => {
       columns.LoadSettings(Model.columns);
    })
    .Events(ev=>{
        ev.Filter("onFilter");
        //ev.FilterMenuInit("filterMenuInit");
    })
    .Pageable()
    .Sortable()
    .Scrollable()
    .Filterable()
    .DataSource(dataSource => dataSource
        .Ajax()
        .PageSize(20)
        .Read(read => read.Url(Url.Action()+"?handler=Read").Data("forgeryToken"))
     )
)
</div>

This is a portion of the gridcolumnsetting code for brevity.  The column that needs a custom filter menu is the SERIAL_NO.
