This is actually a combobox within the RadGridView but my c# syntax/datastructure problem is the same. I need a list with two items ClassName and ClassID for a combobox. The possible key-value pairs will be 'A'-0 'B'-2, 'C'-3 and 'D'-4 .
I've been provided a table from a client with either the values "A or B" or "A,B,C,D". (Picture of table info below) I need to translate either of those two possibilities into two possible collections to bind to a combobox. Either the combobox displays an A and B, or A and B and C and D. When the user makes a selection and saves.... the collection (rows in datagrid) will contain within it the key-value pair selected. That value will be returned to target table also pictured below with it's possible values.
If someone can see where I'm trying to go with this I would appreciate any comments or suggestions, even if that comment is I'm not clear what I'm trying to do. I'm stuck with these tables. Below is my idea of a model and then a switch statement I need to put somewhere to translate the incoming value into a form the combo box will require. (to bind to) Thanks for helping me work through this design process in an area new to me. greg
public class Model : INotifyPropertyChanged
{
private string _ClassName;
private string _ClassID;
public Model(Model)
{
}
public string ClassName{ get { return _ClassName; } set { _ClassName= value; RaisePropertyChanged ("ClassName"); } }
public string ClassID{ get { return _ClassID; } set { _ClassID= value; RaisePropertyChanged("ClassID"); } }
public event PropertyChangedEventHandler PropertyChanged;
private void RaisePropertyChanged(String propertyName)
{
PropertyChangedEventHandler handler = PropertyChanged;
if (null != handler)
{
handler(this, new PropertyChangedEventArgs(propertyName));
}
}
}
switch (incoming 'Class' field value in collection)
{
case "A or B":
AorB();
break;
case "A, B, C, D":
ABCD();
break;
}
private ObservableCollection<ClassName> AorB()
{
ObservableCollection<ClassName> _ClassNames = new ObservableCollection<ClassName>();
ClassName _className;
className = new ClassName ("A", 1);
_ClassNames.Add(className );
className = new ClassName ("B", 2);
_ClassNames.Add(className );
return _ClassNames ;
}
private ObservableCollection<ClassName> ABCD()
{
ObservableCollection<ClassName> _ClassNames = new ObservableCollection<ClassName>();
ClassName _className;
className = new ClassName("A", 0);
_ClassNames.Add(className );
className = new ClassName("B", 1);
_ClassNames.Add(className );
className = new ClassName("C, 2)
_ClassNames.Add(className );
className = new ClassName("D, 3);
_ClassNames.Add(className );
return _ClassNames ;
}
