Hi to all, I would create a view to show several custom functions before grid, these functions will generate several effect to loading data into a grid.

But I would also a Export Excel button, but not above the grid, but enternally, into a div group that contains other controls.

How can I do this?

I don't want use ToolBar of grid.

Can i call a javascript code for example $("#myGrid").exportExcel(); ? Is it possibile?

Hey,

I know there are ways to automatically validate with a kendo validator on a form. However, when I set a min and max value on a Numeric Text Box, after leaving the text box focus, it automatically corrects the value to said range, so the validation always passes. I may be missing it, but I don't see an option with the Razor helper to disable the autocorrect. Is this an option in the .NetCore version or do I need to override this somehow in javascript? I'd like to avoid that if possible as there are numerous (34 to be exact) numeric text boxes that need similar validation. Below is a sample numeric text box.

@(Html.Kendo().NumericTextBoxFor(x=>x.PlanDefault.EmployerMatchPercentMax).Spinners(false).Value(Model.PlanDefault.EmployerMatchPercentMax ?? 0).Min(0).Max(100).HtmlAttributes(new { @class = "form-control" }))

I have a comboBox

@(Html.Kendo().ComboBox()
                    .Name("contactTypeDropDownList")
                    //.DataTextField("Type") ??
                    //.DataValueField("Type") ??
                    .DataSource(source =>
                    {
                            source.Read(read =>
                            {
                                read.Action("GetContactTypes", "ListBox");
                            })
                            .ServerFiltering(true);
                    })
                    .SelectedIndex(0)

 

the action returns items of enum

public IActionResult GetContactTypes()
{
    var contactTypes = new List<ContactTypes>();
 
    contactTypes.Add(ContactTypes.Company);
    contactTypes.Add(ContactTypes.Person);
 
    return Json(contactTypes);
}

 

this enum contains DataAnnotation with "caption"

public enum ContactTypes
    {
        [Display(Name = "Società")]
        Company = 0,
        [Display(Name = "Persona")]
        Person = 1
    }

 

how can I retrieve this "caption" into DataTextField property?

I followed all of the instructions to install Telerik into my exising ASP.NET Core 2.1 application and it all worked fine. The application compiled fine and came up in the website, but when the Index page loaded the date picker did not work and was just a simple text box.

I did not miss any of the steps from what I can see, so I'm not sure why this would not be working.

I'm using Visual Studio 17, and this is an ASP.NET Core 2.1 application.

I'm evaluating Telerik to see if it will be a fit for my needs. The controls look great, but I need to get them working to test this out.

Any help or advice would be greatly appreciated.

How can I get the timeline control to show events in reverse chronological order, I am using the control to show a vertical timeline but would like the most recent dates to appear at the top, I tried the obvious things like reversing the order of the items in the data I was sending to the control but it seems to make no difference.

Hopefully I am just missing something obvious!

Regards

Hi to all,

I followed example in dojo to do this (example in dojo.PNG) that is exactly what I need.

In my case, instead, I'm using a text/x-kendo-template, it's an only difference between my code and example's dojo.

Instead see same effect, I found that my grid is overflowed of window perimeter (examplemy grid.PNG), to see the footer of my grid I need to scroll down at the end (end of grid overflowed.PNG)

This is my style script

style>
    #itemLedgerEntriesWindow {
        padding: 0;
    }
 
    #ileGrid {
        border-width: 0;
        height: 100%; /* DO NOT USE !important for setting the Grid height! */
    }
    #ileTemplate {
        border-width: 0;
        height: 100%; /* DO NOT USE !important for setting the Grid height! */
    }

This is my code

<!--Template della window relativa ai dettagli-->
<input type="hidden" id="purchaseKey" name="purchaseKey" value="false" />
<script type="text/x-kendo-template" id="ileTemplate">
        <input type="hidden" id="itemNoKey" name="itemNoKey" value="#= No #" />
        @(Html.Kendo().Grid<ItemLedgerEntryModel>()
                    .Name("ileGrid")
                    .Filterable()
                    .AutoBind(true)
                    .Columns(columns =>
                    {
                        columns.Bound(f => f.DocumentNo);
                        columns.Bound(f => f.OrderNo);
                        columns.Bound(f => f.VendorNo);
                        columns.Bound(f => f.PostingDate).Format("{0:dd/MM/yyyy}");
                        columns.Bound(f => f.EntryType);
                        columns.Bound(f => f.UnitOfMeasureCode);
                        columns.Bound(f => f.Quantity).Format("{0:N2}").HtmlAttributes(new { style = "text-align: right;" });
                    })
                    .Sortable() // Enable sorting
                    .Pageable()
                    //.Scrollable(scrollable => scrollable.Virtual(true))
 
                    .DataSource(dataSource => dataSource //Configure the Grid data source.
                        .Ajax() //Specify that Ajax binding is used.
                        .PageSize(25)
                        .ServerOperation(true)
                        .Read(read => read.Action("LedgerEntries", "ItemLedgerEntry").Data("itemNoData"))
                    ).ToClientTemplate()
                    )
</script>
 
<!--Window dei dettagli dell'articolo-->
@(Html.Kendo().Window()
        .Name("itemLedgerEntriesWindow")
        .Title("Movimenti Magazzino")
        //.LoadContentFrom("GetItemLedgerEntries", "Home")
        .Visible(false)
        //.Iframe(true)
        .Height(600)
        .Width(1100)
        //.Resizable()
        //.Draggable()
        .Modal(true)
        //.Events(e=>e.Activate("onActivateIleWindow"))
    )

Hi,

we try to use the Grid in Razor Pages (not MVC).

So we have only the page and the page model, not view, controller and model.

All works fine, but how to enable AJAX editing with popup form?

To define the update, create, read and destroy actions via HTML Helper, we need a Controller for the CrudOperationsBuilder. But we dont have one.

Do you have an example, how we can achieve this with Razor Pages?

Thanks in Advance

Ralf

Hi,

Just putting this here in case anybody else might like to use the new Razor Pages:

Here is how I bound to a PageModel (ie no Action or Controller)

 

So the PageModel simply has a public property

public List<MyOjectToBindTo> {get;set;}

 

@(Html.Kendo().DropDownList()
                  .Name("size")
                  .BindTo(new List<MyOjectToBindTo>(Model.MyOjectToBindTo))
                  .DataValueField("Id")
                  .DataTextField("Name")
                  .HtmlAttributes(new { style = "width: 100%" })
    )

I am using Grid and via BindTo(...) it displays a list of objects from my PageModel; this works fine.

@(Html.Kendo().Grid<ProjectImportFormat>()
    .Name("grdProjectImports")
    .BindTo(Model.ProjectResults)
    .AutoBind(true)

...)

 

What I like to do is display the count of all records in the footer of the grid. Normally aggregates are declared inside the datasource, but there is only a list, no datasource. How can this be accomplished?

Regards
Heiko
