Hello.
I have 2 issues.
C1.WPF.Grid.Ja 5.0.20203.37
.NET5
1. Sort of DataGrid is OK. FlexGrid sort throws null exception.
DataGrid
<DataGridTemplateColumn
Width="140"
CanUserSort="True"
Header="MembersB[2] 2"
SortMemberPath="MembersB[2].Name">
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<TextBox Text="{Binding Path=MembersB[2].Name, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}">
<TextBox.Style>
<Style TargetType="{x:Type TextBox}">
<Style.Triggers>
<!-- https://stackoverflow.com/a/15567948/9924249 -->
<DataTrigger Binding="{Binding Path=MembersB[2].Name.Length, FallbackValue=0, TargetNullValue=0}" Value="0">
<Setter Property="Foreground" Value="Red" />
</DataTrigger>
</Style.Triggers>
</Style>
</TextBox.Style>
</TextBox>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
FlexGrid
<c1:GridColumn
Width="140"
AllowSorting="True"
Header="MembersB[2] 2"
SortMemberPath="MembersB[2].Name">
<c1:GridColumn.CellTemplate>
<DataTemplate>
<TextBox Text="{Binding Path=MembersB[2].Name, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}">
<TextBox.Style>
<Style TargetType="{x:Type TextBox}">
<Style.Triggers>
<DataTrigger Binding="{Binding Path=MembersB[2].Name.Length, FallbackValue=0, TargetNullValue=0}" Value="0">
<Setter Property="Foreground" Value="Red" />
</DataTrigger>
</Style.Triggers>
</Style>
</TextBox.Style>
</TextBox>
</DataTemplate>
</c1:GridColumn.CellTemplate>
</c1:GridColumn>

2.
When one of indexed properties is null for FlexGrid, null exception is thrown.
DataGird is OK.
ex:
Row1: MembersB[1] = p1;
Row2: MembersB[1] = p2;
Row3: MembersB[1] is null
fig2.
Could you fix these exceptions?
