ClearGrouping and System.InvalidCastException

[Francois]

Hi,

Context:

I am developing a DataGrid component with a custom adapter.

In the DataGrid, I add a custom button called “RAZ filters”. This button clears all searches, groupings, filters, sorts, and focuses.

I’m using Blazor server in prerender mode. The Syncfusion NuGet is 19.1.0.59.

Problem:

Unfortunately, I experience problems with the clear grouping functionality (called by “RAZ filters” button). In some cases, it fails with System.InvalidCastException.

This fail only appears in some configurations of the dataGrid component.

The condition that seems mandatory to make this problem appears are:

• At least one column has the parameter AutoFit equals true.

• The parameter EnablePersistence of the grid equals false.

• The parameter GridSelectionSettings of GridSelectionSettings equals true.

I attached an example that reproduce the problem. It is not the DataGrid component I’m using in my project but a simplified version

Thanks for your help.

Best regards.

François

Today, I updated the NuGet to 19.1.0.64 and the problem disappears from the attached example but it persists in my DataGrid component.

I will update this thread if I have more information or another example.
