Hi
I'm newbie in using SF components and I want to ask you for little help. I want to use sfAutoComplete entry inside of template column in sfDataGrid in my MVVM project. Please tell me how can I bing SelectedValue property of sfAutoComplete to my business model?
XAML
<sf:SfDataGrid x:Name="dataGrid2"
ItemsSource="{Binding CKTypeSelector}"
AllowEditing="True"
NavigationMode="Cell"
SelectedItem="{Binding selCKType}"
SelectionMode="Single"
EditTapAction="OnDoubleTap"
EditorSelectionBehavior="MoveLast"
AllowPullToRefresh="False"
LiveDataUpdateMode="AllowDataShaping"
GroupingMode="Multiple"
ColumnSizer="Star"
AutoGenerateColumns="False"
AllowSorting="True"
VerticalOptions="FillAndExpand"
HorizontalOptions="FillAndExpand"
>
<sf:SfDataGrid.Columns>
<sf:GridTextColumn HeaderText="{extensions:Translate lblName}"
MappingName="Name"
AllowEditing="False" />
<sf:GridTemplateColumn HeaderText="{extensions:Translate lblValue}"
MappingName="selControlKey_ID"
MinimumWidth="200">
<sf:GridTemplateColumn.CellTemplate>
<DataTemplate>
<sfACompl:SfAutoComplete x:Name="autoComplete"
DataSource="{Binding PickerControlKeys}"
DisplayMemberPath="Name"
SelectedValuePath="ID"
SelectedValue="{Binding ??????? selControlKey_ID ???????}"
MaximumSuggestion="5"
AutoCompleteMode="Suggest"
SuggestionMode="Contains"
HighlightedTextFontAttributes="Bold"
HighlightedTextColor="Red"
DropDownTextSize="10"
DropDownItemHeight="14"
TextSize="12"
LoadMoreText="{extensions:Translate lblLoadMore}"
NoResultsFoundText="{extensions:Translate lblNoResult}" />
</DataTemplate>
</sf:GridTemplateColumn.CellTemplate>
</sf:GridTemplateColumn>
</sf:SfDataGrid.Columns>
</sf:SfDataGrid>
ViewModel
public class AccControlKeyTypeSelector
{
public AccControlKeyTypeSelector() { }
public int ID { get; set; }
public string Name { get; set; }
public ICollection<PickerControlKeys> PickerControlKeys { get; set; }
public int selControlKey_ID { get; set; }
}
public class PickerControlKeys
{
public PickerControlKeys() { }
public int ID { get; set; }
public string Name { get; set; }
}
public class BudgetTypePageViewModel : BaseViewModel, IBudgetTypePageViewModel
{
private ObservableCollection<AccControlKeyTypeSelector> _cktypeselector = new ObservableCollection<AccControlKeyTypeSelector>();
private AccControlKeyTypeSelector _selcktype = new AccControlKeyTypeSelector();
public ObservableCollection<AccControlKeyTypeSelector> CKTypeSelector
{
get { return _cktypeselector; }
set
{
_cktypeselector = value;
OnPropertyChanged(nameof(CKTypeSelector));
}
}
public AccControlKeyTypeSelector selCKType
{
get { return _selcktype; }
set
{
_selcktype = value;
OnPropertyChanged(nameof(selCKType));
}
}
..........
}
and some code to fill collections, which works OK.
DataGrid must display values from CKTypeSelector collection in rows (about 7 rows), every CKTypeSelector item has its own collection of exact PickerControlKeys and the selControlKey_ID property to store ID of one ControlKey value selected from PickerControlKeys collection.
Suggestion box works and shows values what I want and I'm able to select one of these. Bud when I select the ControlKey value, it is not written into CKTypeSelector.selControlKey_ID or selCKType.selControlKey_ID.
Please give me some hint to resolve this little stupid problem. Thnx a lot.
David
