Hello,
I believe I've found an issue with the DataGrid Column Picker. If you use both the 'DropDown' and the external toggle (change visible state of the column), you can end up in a state where a click on the toggle button "get lost".
You can reproduce this behavior at Blazor DataGrid Component - Column Picker | Free UI Components by Radzen using the following click path.
Click path:
Dropdown: enable Id Column > Id will be shown > Click on "Toggle EmployeeId column visibility"
Nothing happened on 1st click.
The 2nd click works as expected.
I'm going to dig around in the code again to see if I can figure out what's going on. I'll let you know as soon as I have a clue.
thanks for your support!
best regards
