how to validate the input by another list

[YN]

Hello,

I'm new to UI for Asp.net core. I met a problem here.

 

I have a table "authors" , contains all the author id [A,B,D,G,F]

and I have another table "books", it will be a Grid, showing book name, author name, when inline editing, user can update the author name for the book. when user input 'C', then notify him put a wrong author name. because our list is [A,B,D,G,F] has no C.

 

how to do this?   or how to put a check box list when inline editing a row in Grid?

Hi Sarah,

A possible solution would be to create a custom validation rule as shown in the following demo:

Regarding the custom editors, the following article contains a detailed information how to create a custom editor for a column:

• https://docs.telerik.com/aspnet-mvc/helpers/grid/templating/editor-templates

I hope this helps.
