I have an asp.net core razor page app im trying to make an edit page I would like to add a Telerik grid to bind to a list of objects that I have declared as a bind property. The Grid is displaying great but when the form posts back I want the grid to modelbind to the list and pass back in the new records, changed records, and delated actions done in the grid.  This is not happening and if I use the bind property or pass the parameter on the onpost I can't get the grid values passed back.

   In the code behind

  public class HowToUseSteps

    {

        public int Id { get; set; }

        public string Steptext { get; set; }

    }

  [BindProperty]

        public  List<HowToUseSteps> _Steps { get; set; }

in the cshtml

<form method="post">

              @(Html.Kendo().Grid(Model._Steps)

              .Name("HowToUseSteps")

              .Editable(editable => editable.Mode(GridEditMode.InCell))

              .Columns(columns =>

              {

                  columns.Bound(column => column.Id).Title("Id").Width(100);

                  columns.Bound(column => column.Steptext).Title("Step");

                  columns.Command(command => command.Destroy()).Width(150);

              }

           )

                .ToolBar(toolbar =>

                {

                    toolbar.Create();

                    toolbar.Save();

                })

                    .DataSource(dataSource => dataSource

        .Ajax()

        .PageSize(20)

        .ServerOperation(true)

     )

    <button type="submit" class="btn btn-success">Save</button>

</form>

I know i can call separate on change on delete events on the grid. but i was hoping to use databinding on a postback instead.  any help would be appricated. 

Thanks

How to display the real value without formating.

Default formating is N2 :

Value : 10.567

Display: 10.56 or 10.57 with round

Change formating to N8 :

Value : 10.5678

Display: 10.56780000

I would like to display 10.567 or 10.5678 without 0, as in edition.

Thx.

                    <label for="poNumTextbox" style="color:white; line-height:3.2; padding-right:5px; padding-top:5px">PO#</label>
                    <div class="k-textbox" style="width:120px">
                        @(Html.Kendo().NumericTextBox<int>()
                            .Name("poNumTextbox")
                            .Format("#")
                            .Decimals(0)
                            .RestrictDecimals(true)
                            .Placeholder("PO #")
                        .HtmlAttributes(new { style = "font-size:inherit; width: 100%" })
                        .Spinners(false)
                        )
                    </div>

I am trying to figure out how to keep leading zeros. Numbers can be something like "00045678" with max 8 chars. However when you click out of the textbox, it is converted to "45678" I'm using numeric textbox to prevent entry of non-numeric characters. Also no decimals or special characters - numbers only. 

Thank you.

edit: nevermind, found that MaskedTextbox gives me what I need without having to misuse NumericTextbox

Hi,

I am trying to get the id of the selected entry in a combo box on a Razor page.

I modelled the code on the DatePicker example from the Razor examples.

I added a DatePicker to my page along with my Combo box.

The page loads and the combo box loads its entries. When I make a selection, the page does a post and my OnPost handler is called.

The value for the DatePicker is there but the ComboBox returns a null value.

I have enclosed screen shots of my cshtml and cshtml.cs pages. The DatePicker and ComboBox are setup identically as far as I can tell.

Any suggestions on what I might be doing wrong. 

Thanks,

Charlotte

So, basically I do not want clients to have the options to delete or rename files which they have by default when you use FileManager through tag helper. All I need is clients to be able to view available files and download them. Is there any alternative to FileManager to achieve this feature? I greatly appreciate any help or directions. Thank you.

Edit: Using <Context-Menu> tag helper inside the filemanager component accomplished what I was looking for.

What is the usage of UnmaskOnPost?
It seems that if the value is true or false the unmasked text is passed to the ViewModel/Model/Controller.

I need the masked value to be passed for additional validation.

Good afternoon,

I have created a pie chart based on a ViewModel that contains:
int OperatorId,
string OperatorName,
int OperatorTotal

The chart series is created with a click event as:

            .Series(series => series
                    .Pie(model => model.OperatorTotal, model => model.OperatorName)
                    .ColorField("Color")
                    .Padding(0)
            )
            .Events(events => events.SeriesClick("onPieChartClick"))

I can access e.series.name and e.category in the click event which gives me the OperatorName, but I really need the OperatorId.

Is there a way that I can group the pie chart by Id but display the name, or pass the Id in the click event?

Many thanks

Richard
