Hi Team
I need some help, have a combo box, it suppose when loading the application it loads the recipe codes name on the combo box, but its not but the data is on the grid fine. Maybe there is a property that is conflicting with this. Below is my logic
<!---Stock code variable holder--> <UserControl.Resources> <CollectionViewSource x:Key="StockCode" Source="{Binding Code}"/> <CollectionViewSource x:Key="StockDescription" Source="{Binding Description}"/> </UserControl.Resources> <!---Recipe name and drop down box--> <Label x:Name="lblDriverName_Copy" FontWeight="SemiBold" Visibility="Visible" Content="Recipe Code:" HorizontalAlignment="Left" VerticalAlignment="Top" Width="179" HorizontalContentAlignment="Right" Background="#FFE3E3E3" Margin="17,65,0,0" BorderThickness="1" BorderBrush="#FFBEBEBE"/> <ComboBox x:Name="cbxRecipe" TabIndex="1" IsTextSearchEnabled="True" IsEditable="True" IsTextSearchCaseSensitive="False" Foreground="Black" HorizontalAlignment="Left" Margin="207,63,0,0" VerticalAlignment="Top"
