Combobox in WPF unable to add hardcode values with database values
XAML Code:
<ComboBox x:Name="CbLinge" HorizontalAlignment="right" Margin="0,150,0,0" VerticalAlignment="Top" Width="300" Height="25" RenderTransformOrigin="1.018,0.565 "
ItemsSource="{Binding GetLinge}"
DisplayMemberPath="Linge"
SelectedValuePath="Linge"
SelectedValue="{Binding FinishedManual.Ligne}"/>
C# Code:
public void _fillLinge()
{
List<FinishedManualPrintingLinge> linge = _finishedProductService.GetFinishedManualLinge().ToList();
foreach (var item in linge)
{
GetLinge.Add(item);
}
}
By This piece of code,I'm able to get the values from database and able to display in Dropdown.
Problem:
The dropdown list for "Ligne" is linked to data available in order table. But if any order for the line, then it is not visible in drop-down "Ligne". So, it should be hardcoded/ populated by (1,4,6,7,8,9,10).
Now, I am not sure how to display the hardcode values if order : x is selected.

What do you mean by But if any order for the line, then it is not visible in drop-down "Ligne".?

@Alain: example we have 1 more drop-down above which is displaying orders. Now if user select the order which doesn't have and existing value of linge. So in that case my drop- down will show (1,4,6,7,8,9,10) values.

So you want to have aFallBackvalue for your collectionBinding. It is easy enough, also you clicked on combobox and rotated it a bit, you don't needSelectedValuePathwhen you useSelectedValue.

OPTION 1
Display a hardcoded set of values:
Here is how I have done it:
<ComboBox ItemsSource="{Binding GetLinge, TargetNullValue='123456789', FallbackValue='123456789'}"/>
In your case you would use the TargetNullValue to populate the values. The 10 might be a bit tricky as the string is IEnumerable so it will pick single characters from the array. But I think this will push you in the right direction.
OPTION 2
Another option is to modify your public void _fillLinge() method and let it return default values if there aren't any found.
OPTION 3
Another Option would be to use a converter which would then supply the default items instead of modifying the public void _fillLinge() method.
The choice is yours.
