Hi all,

 

So I've seen a couple of questions about this, but none of the solutions have helped. 

I'm attempting to build something like this demo for Asp.Net Core 2.0:  https://demos.telerik.com/aspnet-core/grid/checkbox-selection

 

When I set up the app, I don't get the checkboxes in the grid.  I've tried multiple browsers.

 

I'm using version 2017.3.1206.  I built a test project to try to get this to work, building off the code in the above demo.

 

Here is my view:

 

 

Here is my controller:

 

 

Here's my _Layout.cshtml:

 

The grid renders fine, but the selection columns are empty.  Any help is appreciated - thanks!

I want to persist grid state whenever a column width, order, or visibility state is changed such that when a user visits the same page in the future the columns are in the same state.  I don't want to require an extra button click after the user makes a change to column state.

I am familiar with having a client template for a Boolean column to display "Yes" or "No" for true or false.  I have many templates that use the syntax below with no problems yet this grid on one template will show no data at all if I display that column.  If I comment it out the data shows fine.

 

 

I can observe the 5 records that are returned in the grid's Read method in the debugger and see that the non null able column has valid values

 

Any suggestions?

I created a grid with a dropdown.  The drop down has an Id and a Name.  The name is what the user should see and the Id is what the system will use.

 

When using inline editing, the drop down appears ok, but when selecting the item, the data doesn't go back to the service and when in display mode nothing is shown.

 

It wont let me attach an example:

 

here is the code

  public class ReferenceData
    {
        /// <summary>
        /// Gets or sets the identifier of the model.
        /// </summary>
        /// <value>
        /// The identifier of the model.
        /// </value>
        public int Id { get; set; }

        /// <summary>
        /// Gets or sets the name.
        /// </summary>
        /// <value>
        /// The name.
        /// </value>
        public string Name { get; set; }
    }

public class GridRowViewModel
    {
        /// <summary>
        /// Gets or sets the identifier of the model.
        /// </summary>
        /// <value>
        /// The identifier of the model.
        /// </value>
        public int Id { get; set; }

        /// <summary>
        /// Gets or sets when the career gap started.
        /// </summary>
        /// <value>
        /// the start of the career gap
        /// </value>
        public DateTime From { get; set; }

        /// <summary>
        /// Gets or sets a value indicating whether [qualifying service].
        /// </summary>
        /// <value>
        ///   <c>true</c> if [qualifying service]; otherwise, <c>false</c>.
        /// </value>
        public bool Flag { get; set; }

        /// <summary>
        /// Gets or sets the reason.
        /// </summary>
        /// <value>
        /// The reason.
        /// </value>
        public ReferenceData ReferenceData { get; set; }

        /// <summary>
        /// Gets or sets the reason identifier.
        /// </summary>
        /// <value>
        /// The reason identifier.
        /// </value>
        public int ReferenceDataId { get; set; }

        /// <summary>
        /// Gets or sets when the career gap ended
        /// </summary>
        /// <value>
        /// The end of the career gap
        /// </value>
        public DateTime To { get; set; }
    }

public class IndexViewModel
    {
        public IList<ReferenceData> ReferenceDataList { get; set; }
    }

Is there an example of Kendo UI async Upload on Razor pages (No controller) ? I tried below but I get 404 error .

 

<div class=""> @(Html.Kendo().Upload() .Name("files") .Async(a => a .Save("Save", "UploadManagement/Index") .Remove("Remove", "UploadManagement/Index") .AutoUpload(true) ) ) </div>

 

[HttpPost]public ActionResult Save(IEnumerable<IFormFile> files){}

Hello,

How can i call the Get method of my controller ? When i load my page, it's only calling the Post Method. I followed the web api events exemple. Thank you.

 

 

Is it possible to read a DataSource using a Route Name rather than a Controller / Action ? 

Hi folks,

I'm trying to build custom create and edit buttons to navigate to a totally new view, rather than using inline or popups. I've got the edit one to work using a JavaScript function to redirect to the edit view, but can't seem to get the create one to work.

Here's my grid:

@(Html.Kendo().Grid<Project.Models.Organisation>()
.Name("grid")
.HtmlAttributes(new { style = "ScrollHeight: 700px" })
.Columns(columns =>
{
columns.Bound(c => c.Name).Width(80);
columns.Command(command =>
{
command.Custom("Details").Click("showDetails");
}).Width(20);
})
.Sortable()
.Filterable()
.Pageable(x => x.PageSizes(new int[] { 5, 10, 15, 20, 100 }).Refresh(true).ButtonCount(5))
.ToolBar(toolbar => {
toolbar.Custom().Text("Create").HtmlAttributes(new { id = "showCreate" });
})
.DataSource(dataSource => dataSource
.Ajax()
.PageSize(10)
.Events(events => events.Error("error_handler"))
.Model(model =>
{
model.Id(p => p.Id);
model.Field(p => p.Name);
})
.Read(read => read.Action("List", "Organisations"))
)
)

Here's the edit function, which works fine:

function showDetails(e) {
e.preventDefault();
var dataItem = this.dataItem($(e.currentTarget).closest("tr"));
window.location.href = '/Organisations/Details/' + dataItem.Id;
}

And here's the create function, which doesn't appear to do anything:

function showCreate(e) {
e.preventDefault();
window.location.href = '/Organisations/Create/';
}

I've tried a couple of approaches:

1) In ASP.NET examples, you appear to be able to do the following to fire a controller method directly, is this not available in Core?

toolbar.Custom().Text("Create").Action("Create", "Organisations");

2) Another approach that appears possible from research is to use HtmlAttributes, but this appears to do nothing, am I missing something?

toolbar.Custom().Text("Create").HtmlAttributes(new { id = "showCreate" });

I'm pretty new to ASP Core, so any pointers would be gratefully received.

Thanks,
Dave.

I have a dropdown list that has a source where multiple items have to be displayed based on a parameter. I have activated the virtualization and a method of ValueMapper has to be provided.

 

On this javascript function I have to call again using ajax but I have to send also the datasource parameter.

 

Is there a way from the ValueMapper function to get to the dropdownlist? I do not want to know the name of the dropdownlist because this functionality should be used by multiple dropdownlists.

I tried to get to the dropdownlist from the this object but it seems that the function is called in the context of some kind of virtual object and not the dropdownlist
