I'm getting error for dynamic Grid InCell editing. Error is displayed on editing before calling UpdateHandler. It is observed for adding new row or editing any row. 

Error: System.ArgumentException: Instance property 'x' is not defined for type 'System.Dynamic.ExpandoObject' (Parameter 'propertyName')

I was not getting this error In previous version 2.21.0 on edit of a dynamic field. Getting this error after updating to new 2.23.0 version without any code change.

Please make the source code available to people with paid licences.

ADMIN EDIT

The source code for UI for Blazor will become available. Click the Follow button on the upper left hand side to get a notification email when that happens, and click the Vote button to add your vote for it if you need it.

The current plan is to make the source code available to commercial license holders in November 2021.

Having the ability to specify sections and then allowing the user to expand the section can be very helpful for complex content or menus.

The sections can be expanded so 1 is visible always or multiple can be expanded.

Sometimes it is helpful to allow the user to pick colors for various purposes.

This control can display the RGB value along with allowing them to change the hue/brightness along with the alpha component.

Also the ability to select from a set of predefined colors would be very nice.

ADMIN EDIT

Here is a sample project that showcases how you can use Kendo widgets in Blazor and also contains samples of color pickers: https://github.com/telerik/blazor-ui/tree/master/common/kendo-in-blazor

I'd like at least a linear gauge

how to use Multiple Column Header in grid?

thanks

Hi,

Is it possible to implement search/look-ahead in the current version of the DropDown component? If not, will you be adding this feature soon?

Thank you.

Ben

Like the grouping in the Kendo combo box https://demos.telerik.com/kendo-ui/combobox/grouping

<AdminEdit>

This Feature Request would be an umbrella for implementing items grouping for select components (ComboBox, DropDownList, MultiSelect, and others).

</AdminEdit>

Transitioning our application from Telerik React to Blazor, our comboboxes in our React application are hooked up to OData endpoints because of the amount of data they could display, some as large as 30mb of json.

Server filtering, https://feedback.telerik.com/blazor/1447481-server-filtering-with-custom-data-request-event-that-can-accommodate-remote-data, almost works, however:

• I can't set PageSize on the combobox
• I can't set TotalCount on the combobox
• Using Telerik.Blazor.ExtensionMethods.ToOdataString throws a NullReferenceException when I try to use it in the ReadItems method with the ComboBoxReadEventArgs args.Reqeuest.ToOdataString()

I tried setting up my combobox like my OData Grid, i.e.

<TelerikComboBox Data="@Dtos"
                         OnRead="@ReadItems"
                         Filterable="true"
                         Placeholder="Find what you seek by typing"
                         @bind-Value="@SelectedValue"
                         TextField="Name" 
                         ValueField="Id"
                         Pageable="true" 
                         PageSize="20" 
                         TotalCount=@Dtos.Count
                         >

However it throws an exception:

blazor.webassembly.js:1 WASM: System.InvalidOperationException: Object of type 'Telerik.Blazor.Components.TelerikComboBox`2[[MyType, MyNamespace, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null],[System.Guid, mscorlib, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e]]' does not have a property matching the name 'Pageable'.

Was hoping this would 'just work' like it does with the Grid, which is amazing!
