Describe the Bug

We have been migrating our grids to RadzenDataGrid from RadzenGrid. After getting everything else working, it appears that RadzenDataGrid.InsertRow() is not functioning. We have implemented everything from this example and cannot find any differences.

Steps to Reproduce

Clone this repo locally: https://github.com/CloudNimble/RadzenDataGridProblem
Set a breakpoint here.
Hit F5 and let the app run & load.
Click the "Add New Record" button.
Step through it adding a new item.
See that it does not put the row into edit mode.

Expected Behavior

I expect it to behave like the previous RadzenGrid and put a new row in the table and put that row into Edit Mode, just as in this example:

Screenshots

This is what the screen looks like after you click the button in our reproduction project. Confirmed that the breakpoint has been hit at the method has been called. No rows are added, and no additional errors are listed in the Console.

Environment

OS: Windows 11
Browser: Edge
Version: 109.0.1518.70

Additional context

This is currently blocking us from moving to Production.

I've replaced RadzenDataGrid and RadzenDataGridColumn with RadzenGrid and RadzenGridColumn however the insert didn't worked again.

Thanks for looking into it! Odd. I wonder if it's a .NET 7 thing? I'll roll it back to .NET 6 and see if it works.

The last version of Radzen.Blazor that I can guarantee it worked in for RadzenGrid was 3.6.8.

If you want to set those changes as a Pull Request on my repro project, I'll pull it down and see if I can roll back to the last verison / runtime it worked in.

didn't worked with 3.6.8 as well - pull request submitted.

I believe I have identified the problem. The code previously worked on .NET 5.0 with version 3.8.6. I was able to reproduce it locally in an older version of BurnRate.

In previous iterations, calling await gridInstance.InsertRow(item); was sufficient to get the Grid into Edit mode. The record was only committed to the underlying List if it was actually edited.

Instead, I'm now having to call:

ViewModel.Entities.Insert(0, item);
await EditRow(entity);

...and simply remove the blank item from the collection if it is deleted before it is persisted.

I will push an update that shows the codebase working, as well as a repo of it working the way it is supposed to on .NET 5.0. I will update this thread when those two branches have been pushed.

Here's the working version on .NET 7 that bypasses gridinstance.InsertRow(): 187555826e

Here's a repro of a working version on .NET 5 + Radzen 3.6.8: bfd06d45a2

I'd really like it to work the way it did in .NET 5. Hope this helps track the problem down. Thanks so much!

Try latest Radzen.Blazor with .NET 5 - if it works then the problem is caused by a change in the EF DbSet. We've not changed anything related to insert.

OK, I spent quite a bit of time rolling through different versions.

.NET 5 + latest: Working
.NET 6 + latest: Working
.NET 7 + latest: Working
.NET 7 + latest [Initial Checkin]: Still not working

Diff between initial version and working version: https://github.com/CloudNimble/RadzenDataGridProblem/compare/initial-version...dotnet7?expand=1
(Focus on the CloudNimbleGrid.razor change)

It looks like setting some of the properties in the original might be causing the problem:

If you could look into what could be causing the problem from that, I will continue to try to narrow it down on this end tomorrow. Thanks!

@robertmclaws commented on GitHub (Feb 3, 2023):

So I figured out what the problem is. Because the datasource we're using is remote, when the data is loaded well after the Grid is rendered, it's not refreshing the Grid with the new data. We had to set our custom grid wrapper to watch the ViewModel for when the LoadingStatus changed, and call gridInstance.Reload().

@enchev I would suggest that you folks add a RadzenDataGrid.Refresh() method that makes it clear you are just going to update the rendering from the existing data, not reload the underlying data source.

I'll go ahead and close this now. If any future readers want to see the fix, let me know.

I have the very same problem and it's very frustrating. I thought the problem was with me and my code, but thankfully, I did a series of tests to figure out that the problem was the insert method.

Strangely, the insert works the first time but doesn't work the second time I call the insert method.

My project is using .NET 8, so I assume it shares the same underlying issue as with .NET 7.

I need to get this fixed for a project I am working on for a client.
Any attempts at fixing this issue would be very much appreciated :)

I can confirm that this problem only happens when the data source is remote and has changed.
What is the best way to work around this problem?

Hello @robertmclaws , I'm interested in having this fixed. Did you manage to find a workaround for .NET 7/8?
