From my initial experiments and looking at the documentation it seems like the TelerikGrid component doesn't currently have features for performing data validation, is that correct?  If so, are there plans to add validation for the grid, and if so what sort of timescale are we looking at for those?

Hi,

Yes, the built-in validation in the Grid edit forms is on our immediate roadmap, and you should see it available in a few weeks at the most.

Thanks Bozhidar.  Is the roadmap something you could share with the community?  It would be really useful to know which features are coming and in what sort of timescale, it will help us work out what we can use Telerik components for and what we'll need to develop ourselves?

I had a look on GitHub and it doesn't look like the Blazor project is open-source, otherwise I'd track the plans there.

Hello Tom,

We are working on a roadmap page as well, I expect that it will be live in a URL similar to this: https://www.telerik.com/support/whats-new/blazor-ui/roadmap

Things are still quite dynamic, because, while we do have some ideas, we are also trying to follow very closely the feedback we receive, sometimes we even implement features or fixes on the days that we receive requests.

For the time being, A good spot to provide feedback and to see what is popular (i.e., is likely to get implemented sooner) is our feedback portal: https://feedback.telerik.com/blazor. After the roadmap page is live, the feedback portal will still be an important tool that we will continue using to gauge interest and determine priority.

On the source code - we will definitely make it available in the future, probably as a zip package available in your account, like the other suites we have. We are also looking into this too.

All that said, if you have questions, requests, bug reports or just general feedback on how you use blazor, our components and what you would like to see in the future - just reach out to us. A forum thread, a private ticket, the feedback portal are all places we can talk.

Hi Ziga,

The PopUp edit form has an EditForm and supports validation. You can see it in action in this demo: https://demos.telerik.com/blazor-ui/grid/editing-popup

There is also an example in the documentation: https://docs.telerik.com/blazor-ui/components/grid/editing/popup

Hello,

InCell editing and InLine editing cannot have an out-of-the-box validation because that's not how validation in Blazor works. You can read more about this here: https://feedback.telerik.com/blazor/1447439-is-there-a-way-to-implement-custom-validation-in-a-blazor-telerik-grid-when-pressing-save-update-command-button-if-not-is-there-plans-on-providing-custom-validation-as-a-feature-in-the-near-future.

What you can consider is using the OnUpdate and OnCreate events to determine if the data is valid and if not - show a message to the user and put the item back in edit/insert mode through the grid state: https://docs.telerik.com/blazor-ui/components/grid/state#initiate-editing-or-inserting-of-an-item.
