I have a view for Create as well as Edit. My question is can I use those views to show when I click the Create New Popup dialog?

So if I click the Add new record, it'll show the built in grid popup dialog window. Instead of the built in dialog, can I set the grid to show my own Create view? The Create.cshtml? The same goes for the Edit view, when I click the Edit button, can I set it to use the Edit.cshtml instead of the built it edit popup dialog?

Persist grid state on filter or sort action

Good Day,

I am actually looking to find a way to save only filter, sort and current paging options when a user interract with the grid. I have seen this demo https://demos.telerik.com/aspnet-core/grid/persist-state, but I would like it to be automatically instead of having external button to do the action.

I have tried also binding on the databound event using a flag like so, but it only works the first time. My function is a little bit generic, because I would like to automatically do it for every grid in the application without having to configure anything.

    let stateChanged = false;
    $('.k-grid').data('kendoGrid').bind('filter', function (e) {
        stateChanged = true;
    });

    $('.k-grid').data('kendoGrid').bind('sort', function (e) {
        stateChanged = true;
    });

    $('.k-grid').data('kendoGrid').bind('dataBound', function (e) {
        if (stateChanged) {
            const grid = e.sender;
            const storageKey = generateStorageKey(grid);
            const options = grid.getOptions();
            saveGridState(options, storageKey);
            stateChanged = false;
        }
    });

Is there any other way to actually save the state of the grid immediately after the user interract with the grid?

Thank you :)

ForeignKey column binding - Combobox editor for data editing

Hi there,

I want to use Combobox editor for data editing, but it only used with local binding:

@(Html.KGrid(gridInfo).Columns(d=>d.ForeignKey(p => p.TableName, (System.Collections.IEnumerable)ViewData["TableNames"], "Id", "Name")))

@(Html.KGrid(gridInfo).Columns(d=>d.ForeignKey(p => p.TableName, ds => ds.Read(r =>r.Url("/sys/gridinfo/gettablenames")), "Id", "Name")))

If I use remote binding it show Dropdown List editor, I tried .EditorTemplateName("GridForeignKey") but it doesn't work.

Editor template GridForeignKey:

@model object
@(
 Html.Kendo().ComboBoxFor(m => m)
        .ValuePrimitive(true)
        .Filter("contains")
        .BindTo((SelectList)ViewData[ViewData.TemplateInfo.GetFullHtmlFieldName("") + "_Data"])
)

I hope to get help, thanks!

Losing selected rows when changing page

I am using the Kendo grid to show data. I am also using a function to export the selected rows to excel. The thing is, if I select multiple rows from multiple pages it only export the rows from the last page or the page I am currently at.

<div class="container">

        });
        kendo.saveAs({ dataURI: workbook.toDataURL(), fileName: fileName });
    });

Any pointers or suggestions on how to proceed? How not to lose the rows from the previous pages?

How do I call the read and filter method?

I have a grid that I have made external filters for. When a user chooses a filter option, I basically call:

grid.dataSource.filter(filterObj);

However, my grid's read method requires params, which is called like this:

var optionalData = { startDate: startDateVal, endDate: endDateVal };
grid.dataSource.read(optionalData);

When the user chooses a filter, the 1st filter method is hit but my application errors on the read method because it is expecting parameters that are now null. (the startDate and endDate).

How do i call the filter method and pass optional data to it? I assume the filter calls a read?

How do I open a Razor Page in a Kendo Window?

Hi,

I have been using UI for ASP.NET AJAX for over 10 years and have used the radWindow to display a page containing a details, create or edit form as follows:

window.radopen("rw/Project.aspx?Id=" + id + "&pt=" + projecttype, "PopUpWin1");

Having finally made the leap to Razor Pages, I cannot see how to adopt this technique using UI for ASP.NET Core. I can see that you have integrated Grid and Window create and edit functionality but, in this case, I cannot use a Telerik Grid and have to use an existing custom control with a table in it to render the data rows in a foreach loop. If it's possible, I'd prefer to keep this Razor Pages than MVC for a number of reasons. Please let me know if you need any further information.

Many Thanks,

Craig

Bind Upload widget to Model Property - ASPNET CORE MVC - UPLOAD

I have a grid that is using a custom editor template (pop up). I would like when a user is ready to create a new entry, they have the choice to upload a list of files as well.

In my custom editor I have this:

 @(Html.Kendo().Upload()
            .Name("files")
            .HtmlAttributes(new { aria_label = "files" })
        )

In my Grid model, it has a member that looks like this: (Entry is the class name)

public IEnumerable<IFormFile> files {get;set;}

And my controller signature looks like this :

public ActionResult Create_Entry(Entry entry, [DataSourceRequest] DataSourceRequest request)

However Entry.files is always null. I cant seem to get the file upload widget to bind to that mode property?

I have tried adding an extra parameter for files in the controller params but that doesnt work either.

Any help is appreciated.
