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.

Currently, calling the ClientTemplate method of the Grid's ToolBar overrides any previously defined commands. 

It would be really useful to expose an option to use the Template component to define a custom command for the Grid's ToolBar, instead of having to rewrite the entire TollBar in the ClientTemplate configuration.

I'm currently evaluating the ASP .Net Core Components and whilst I'm liking it so far, I have to say - the documentation leaves a lot to be desired.

At the moment, I am trying to use grid and looking at documentation, I have no idea if I am meant to be looking in Kendo.Mvc.UI.Fluent or Kendo.Mvc.UI - and when I am there and find an item, there just isn't enough detail. In addition, the demos section appears to actually be more helpful and I'm constantly looking there.

What caused me to write this is that I have simply enabled GridFilterMode.Row on an instance and whilst I like it, I want to change the default from "Is Equal To" to "Contains"... I have been experimenting for the past few hours without any luck and I'm going round in circles on documentation:

I can see that Filterable requires GridFilterMode, but the documentation is lacking - https://docs.telerik.com/aspnet-core/api/Kendo.Mvc.UI/GridFilterMode#kendomvcuigridfiltermode

I then try to find the filterable modes documentation, but, half the features/methods just don't seem to have any affect whatsoever.

Personally, I'm having great luck learning about your components from the demo section and adapting the code to suite my needs - but, if there isn't a demo, it appears to be a very hard task to learn what is and isn't possible.

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?

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

Expose configuration options for setting the options - Size, ThemeColor, FillMode and Rounded - of the Grid's command buttons and toolbar buttons, as possible for a simple Button component.

Adding a separate configuration for the Cancel command button would also be beneficial. For example:

    .Columns(columns => {   
        columns.Bound(p => p.ProductName);
        columns.Bound(p => p.UnitPrice).Width(140);
        columns.Bound(p => p.UnitsInStock).Width(140);
        columns.Bound(p => p.Discontinued).Width(100);
        columns.Command(command => command.Destroy().ThemeColor(ThemeColor.Error)).Width(150);
    })
    .ToolBar(toolbar => {
        toolbar.Create().ThemeColor(ThemeColor.Info).Size(ComponentSize.Large);
        toolbar.Save().ThemeColor(ThemeColor.Success);
        toolbar.Cancel().ThemeColor(ThemeColor.Warning);
    })

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
