Problem showing selected value of combobox when it is bind to a List<T> using Linq to Entities
- by Syed Mustehsan Ikram
I have a combobox which is has itemtemplate applied on it and is bind to a List of entity return using linq. i m using mvvm. It is bind to it successfully but when i set the selected value of it from code at runtime to show the selected value coming from db it doesn't select it. For reference here is my combobox xaml.
SelectedValue="{Binding Path=SelectedManufacturer}"
Grid.Column="3" Grid.Row="2" Margin="20,9.25,68,7.75"
ItemTemplate="{StaticResource ManufacturerDataTemplate}" TabIndex="6"/
Here is my part from code behind from viewModel.
List currentManufacturers
= new List();
tblManufacturer selectedManufacturer = null;
public List CurrentManufacturers
{
get
{
return currentManufacturers;
}
set
{
currentManufacturers = value;
NotifyPropertyChanged("CurrentManufacturers");
}
}
public tblManufacturer SelectedManufacturer
{
get
{
return selectedManufacturer;
}
set
{
selectedManufacturer = currentManufacturers.Where(mm => mm.ManufacturerID == Convert.ToInt32(selectedDevice.tblManufacturer.EntityKey.EntityKeyValues[0].Value)).First();
NotifyPropertyChanged("SelectedManufacturer");
}
}
