GridView: When validating through IDataErrorInfo the tooltip errors are updated only after trying to commit a row edit
Posted on:05 May 2020 05:59
This behavior is still not planned for fixing. I completely understand that this behavior is causing you trouble, but it will require a major refactoring in the core logic of RadGridView's validating mechanism. I am afraid our roadmap is full for the near future, so this task still resides in our backlog.

We tried to solve the problem but the fix actually caused some new ones and we had to revert it. This is why the status of this item is Approved. I cannot commit to any specific date or release where this issue will be fixed as its source is in the core logic of RadGridView's validating mechanism.
Please excuse us for the inconvenience caused.

Hi Telerik Team,
Validation messages on error tooltip should get refreshed not only when row is in edit mode but also when the underlying datacontext is changed through the code.
That means any change on a property that grid binds to should also trigger refresh of IDataErrorInfo errors on UI.
Please fix this soon.

This is not a correct behavior please fix this issue.

Yes this fix is required. It should be fix as soon as possible.

Yes, Errors property implementation behavior should be correct and hence please fix this.

There are issues around IDataErrorInfo. We commented the code for 'Errors' property implementation and returned 'null' to avoid multiple messages. This is not a correct behavior.
