Hello,
I am struggeling with binding to GridComboBoxColumn. It changes the source list of values instead of the collection in grid.
Model (MeetingMinutesItemType):
public class MeetingMinutesItemType: ObservableObject
{
private string name = "";
public string Name { get => name; set => Set(nameof(Name), ref name, value); }
private string? description;
public string? Description { get => description; set => Set(nameof(Description), ref description, value); }
}
Model (MeetingMinutesItem):
public class MeetingMinutesItem: ObservableObject
{
private string? note;
public string? Note { get => note; set => Set(nameof(Note), ref note, value); }
private MeetingMinutesItemType? type;
public MeetingMinutesItemType? Type { get => type; set => Set(nameof(Type), ref type, value); }
}
ViewModel (SidekickMainViewModel)
public class SidekickMainViewModel
{
public ObservableCollection<MeetingMinutes> MeetingMinutes { get; } = new();
public ObservableCollection<MeetingMinutesItemType> MeetingMinutesItemTypes { get; } = new();
}
Model
<syncfusion:SfDataGrid AutoGenerateColumns="False"
ItemsSource="{Binding MeetingMinutes[0].Items}"
AllowResizingColumns="True"
AllowDraggingColumns="True"
AllowDraggingRows="True"
AllowEditing="True"
AllowDeleting="True"
AllowGrouping="False"
EditTrigger="OnTap">
<syncfusion:SfDataGrid.Columns>
<syncfusion:GridComboBoxColumn HeaderText="Typ"
UseBindingValue="True"
MappingName="Type.Name"
DisplayMemberPath="Name"
SelectedValuePath="Name"
ValueBinding="{Binding Path=Type}"
DisplayBinding="{Binding Path=Type.Name}"
ItemsSource="{Binding MeetingMinutesItemTypes, Source={StaticResource MainViewModel}}"/>
<syncfusion:GridTextColumn MappingName="Note"
TextWrapping="Wrap"
HeaderText="Poznámka"/>
</syncfusion:SfDataGrid.Columns>
</syncfusion:SfDataGrid>
Whole code is attached.
This code shows all necessary. The problem is when I want to change the type od the Items. The value is not changed in MeetingMinutes[0].Items, but in MeetingMinutesItemTypes, which is definitely something I do not want.
Where am I doing a mistake?
Cheers.
