Expose the ability to specify an Edit Form Type mode for the Grid similar to the Telerik UI for ASP.NET AJAX control:

https://demos.telerik.com/aspnet-ajax/grid/examples/data-editing/edit-form-types/defaultcs.aspx

Hi

I'm using the popup editor to edit rows in the grid.

I'm using following javascript method to open the popup:

function editSelectedRow(name) {
    var grid = $('#' + name).data('kendoGrid');
    var rows = grid.select();
    grid.editRow(rows[0]);
}

This function is called when a row is double clicked:

$("#Binders tbody").on("dblclick", "tr[role='row']", function (e) {
    editSelectedRow("Binders");
});

I have this code for many years now and it was never a problem.

With the latest version of the grid this code fails (the popup doesn't open) upon making a change in the popup window. As long as no changes is done to the record in the popup, there will not be a problem.

The error received is the following:

jquery-3.7.1.min.js:2  jQuery.Deferred exception: Cannot read properties of undefined (reading 'id') TypeError: Cannot read properties of undefined (reading 'id')

When the data in the grid is refreshed, no error will occur anymore.

HOWEVER... I also have an "Edit" button on the toolbar of the grid. That buttons uses the same 'editSelectedRow' function but when that button is used, the popup window will open, even after a change to the record!!

With other words... something goes wrong when double clicking a row after an update was made.

What has changed?

Best regards,

Grid row drag and drop capabilities enhancement request.

Currently, in order to drop a row from one Grid into another empty Grid, adding a placeholder row to the empty Grid with custom logic is required: https://demos.telerik.com/kendo-ui/grid/drag-drop

It would be nice to have a more robust drag and drop functionality that doesn't rely on custom logic to such an extent.

Is it possible to implement binding of TimeSpan property to TimeDurationPicker editor?

For example:

@model TimeSpan?

@(Html.Kendo().TimeDurationPickerFor(m => m))

I have noticed that neither the HtmlHelper nor the TagHelper wrappers of the Grid's Pageable.Pagesize configuration support the all option to be configured as a page size.

This is unlike the Kendo UI for jQuery pageSize option which supports it as per the example in the API:

 pageable: {
    pageSizes: [2, 3, 4, "all"],
    numeric: false
  }

When a Grid that has a DateTime column is exported to Excel that column doesn't get its width automatically like columns bound to other types of data.

An explicit Width needs to be set for the DateTime column as evident in this Telerik REPL.

Could you please fix the columns.autoWidth of the kendo.ooxml.Workbook to work for all types of data?

Is it possible to add an option to enable/disable the valuePrimitive of the DropDownList editor of a Foreign Key column in the Grid? This way, the ForeignKey column can be configured to allow null values.

I have a model with configured Display and Required DataAnnotation.

However the TagHelper Grid doesn't serialize them because it is lacking a configuration property to bind to a Model like the HtmlHelper does:

@(Html.Kendo().Grid<Kendo.Mvc.Examples.Models.CustomValidationProductViewModel>() 
        .Name("grid")      
        ...
 )

Can this capability be implemented for the TagHelper as well?

Is it possible to implement a method in the Read() configuration of the DataSource that will append parameters as name-value pairs to the query string?

For example:

.Read(r => r.URL(myUrlPath).Handler(myPageHandler).AddQryStrPairs(myNameValuePairsModel))

Currently, I am appending the parameters manually as follows:

.Read(r => r.Url(qurc.PageUrlPath 
 "?handler=Read&area=" +  TkgrArea + "&serviceType=" + qurc.ServiceType.ToString() + "&serviceTag=" + qurc.ServiceTag  + "&entityType=" + qurc.EntityType).Data("forgeryToken"))

Hello Team Telerik,

we have a Grid with a Select column:

...
.Columns(c =>
        {          
                c.Select().Width(50)
....

We want to give users the ability to quickly group rows that are selected. However, grouping the Grid by the Select() column is not possible

Is it possible to implement an option for the Telerik UI for ASP.NET Core Grid to change the default filter operator "eq" to "contains" when the Grid column checkbox filter menu is enabled?

For example:

columns.Bound(p => p.ShipName)
  .Filterable(ftb => ftb
    .Multi(true)
    .Search(true)
    .Operators(op => op
      .ForString(s => s
        .Clear()
        .Contains("Contains")
)));

//Filter expression:
filter: ShipName~contains~'test'
