New Error with guid column since last update

Radzen Studio Blazor Server
1

Good evening,

I have unfortunately two tables which contain a PK-Column which is named guid.

I cannot change this name because other applications rely on that.

Before last update (version < 2.82.2) this was no problem. Now I get an error in those screens where I use a dropdowndatagrid and the ValueProperty is this column guid. I have included a screenshot.

Please can you have a look at that?

Thank you and best regards

Frank

Hi @FrankWuttke,

Do you have this error in the designer only or runtime as well?

Hi Vladimir,

unfortunately also at runtime.

It looks like this:

Hi @FrankWuttke,

You have a property named after system type (Guid) which was causing the error. We've fixed this and you can update the Radzen.Blazor reference in your project to 4.3.9. Radzen with updated reference to Radzen.Blazor will be released later this week.

Thank you, Vladimir!
