I have searched this issue. Fortunately, this feature is included in the new versions.
Hi Necdet,
There's no need to use two DataGrid2 widgets for this.
One approach is to add a Boolean attribute (for example, IsSelected) to your entity, with a default value of false.
In your data source microflow:
IsSelected attribute to true.Then, in your page logic, use this Boolean attribute to determine which row should be treated as the default selection. When the user changes the selection, simply update the Boolean accordingly.
This keeps the page much simpler than maintaining two separate DataGrid2 widgets.
Kindly mark this as the accepted answer if it helps.
