I have a DataGrid. It has a sub DataGrid. It can render ok with version 2.11.14. But render failed with version2.18.3.
my operation is below:
1.click "ADD" button to add a new data. I can't see the new data after saved.
"""
parentDTO.Children.Insert(0, childDTO); //add a new data
"""
2.click sub datagrid delete button. I can't see the changes after saved.
"""
var index = DropDownList.FindIndex(item => item.Id == parentDTO.Id); //find the index of deleting data
DropDownList.RemoveRange(index, 1); //delete the data by index
"""
But every thing is ok with version 2.11.14
