  • Code you have tried ? Datasources ? Linq ? – squelos Mar 08 '12 at 19:01

In your ViewModel, create a SelectedItem property which notifies on change as so: 

private object _selectedItem
public object SelectedItem
{
    get
    {
        return _selectedItem;
    }
    set
    {
        _selectedItem = value;
        OnPropertyChanged("SelectedItem")
    }
}

Bind your SelectedItem property of your combo box to this property.

Then watch for a change on SelectedItem and change your datagrid's source property accordingly.

  • I have a question about this. I have my Combobox populated already with a list property I created. The combobox is populated with a column from my db. I want to be able to select a string from the list in combobox and then have my datagrid populate with other columns from db that are not the combobox property but other properties that share the unique combobox property. I was thinking, should I use linq to fetch all the other columns from db that contain the unique combobox property on selection and then bind that property to datagrid. Does that sound right? – Kala J May 07 '14 at 15:36
