When you change the data source of the grid, it must re-render the data again.
For example, when you use a custom edit form, you add/edit the data with your own code and not through the grid. This is useful, for example, when you only want to show a few columns in the grid, but the model has many more editable fields. Or, when you want a customized layout/behavior of the edit form.
Tooltip is another one of those controls we use everywhere, would like to see a Blazor implementation.
So far in the TelerikGrid component it is only possible to set the title of a column to a string. It would be useful to give the title/header a template instead of a simple string. In this way one could for example place a button, image, (...) inside the columnheader.
This kind of template-ability could be very handy in various other cases elsewhere, so please bring this flexibility into ui for blazor.
Binding a date input or a date picker to a nullable value causes a build-time error
error CS1503: Argument 1: cannot convert from 'System.DateTime?' to 'System.DateTime'
When there are wide columns that produce a horizontal scrollbar, scrolling horizontally does not scroll the headers. It must.
WORKAROUND (see also the rules for the containing div that provides the scroll):
As Razor Components are becoming the next generation of MSFT ASP.Net Core UI and Telerik is also developing new tool called Unite UX, it would be a huge UI design boost for us to visually design Razor Component pages and be able to do responsive test right at design time.
Telerik being a UI company, it's time to move forward with visual designer than writing HTML code in 2019.
I hope the team will give it a consideration.
