[Solved] SelfHierarchy RadGrid with LinqDataSource

[Ivan Zlatanov]

Hi,

I am not sure about the status of what I am about to report, so I will write it for to be sure.

When using radGrid with the SelfHierarchy functionality and LinqDataSource , the default FilterExpression where I specify the default filter for the top parets isn't working correctly. My guess is that it is being applied to child items also.

I replaced the LinqDataSource with SqlDataSource, and it started working as expected - the filter was being applied only to the top master details view.

To replicate this use a LinqDataSource object with any type of select in it - it doesn't matter. Then set a filter - simple example "ParentId == null". It will load the parents correctly, but it will look for their childs wrong. I can also provide simple source code if it is needed to replicate the error.

Let me know about the status of this, because I would really not want to use SqlDataSource instead of LinqDataSource.

Best Regards,

Ivan.

Hello Ivan,

I successfully recreated your scenario on my end. I will need some time to examine this behavior - I will write back to you as soon as I have more information.

Greetings,

Same problem here - I spent a day pulling hair out, suspecting I was doing something stupid.  Any news?

Hello Evgeni,

Unfortunately self-referencing hierarchy and LinqDataSource are not supported at this point. I added this task to our product backlog for future implementation.

Excuse us for the inconvenience.
