Hierarchy Data Grid Force Only One Expand

Radzen.Blazor Components
1

I'm using the RadzenDataGrid that uses hierarchy. I'm attempting to allow inline editing for the records in the child grids. What I'm noticing is that I can achieve this, but only if all other child grids are collapsed. Editing does not work, for example, if I have multiple child grids expanded and I attempt in-line editing on anything other than the last expanded child grid.

It appears that the @ref option on the child grid is set to the last expanded child grid. If there is a way to examine each expanded grid in code, I might be able to work something out. Otherwise, I need to make sure all the expanded child grids are collapsed except for the one I need to edit. Is there a way to do this?

You can set ExpandMode to Single: Blazor DataGrid Component - Hierarchy | Free UI Components by Radzen

There is exactly such template in Radzen Blazor Studio:

Yes, I discovered that if the ExpandMode is set to Single, the confusion about which @ref grid to use is cleared up. I was hoping to be able to have ExpandMode set to Multiple, however.

I think my solution will be to offer options for Multiple or Single. This will allow in-line editing, which requires ExpandMode.Single, and dialog editing which will allow the entire grid to be open.

Thanks for the quick reply
