c#, devexpress - How to make master-detail relation on non-DB objects (List generic )

List<TmpParent> list = new List<TmpParent>();

List<TmpChild> listChildExternal = new List<TmpChild>();
Initial data filling:
var p = new TmpParent( "A", "A", true );
p.listInner.Add( new TmpChild() );
list.Add( p );
list.Add( new TmpParent( "B", "B", false, TypeEnum.OPERATOR ) );
list.Add( new TmpParent( "C", "C", true ) );
list.Add( new TmpParent( "D", "D", false ) );

listChildExternal.Add( new TmpChild() { str1="C", str2 = "child1" } );
listChildExternal.Add( new TmpChild() { str1="C", str2 = "child1.1" } );
listChildExternal.Add( new TmpChild() { str1="B", str2 = "child1.2" } );

gridParent.DataSource = list;	// master
Find and show detail data:
  • First detail list for inner list.
  • Second detail list for external list connected with relation.
private void gridViewParent_FocusedRowChanged( object sender, 
  DevExpress.XtraGrid.Views.Base.FocusedRowChangedEventArgs e ) {

      gridChildExternal.DataSource =

First grid=master, second grid=detail internal list, third grid=detail external list.

c#, devexpress - How to use attributes in GridControl (devexpress)

The attributes in the class can be used as metadata for generated GridControl (devexpress) columns. 

Class for rows:
public enum TypeEnum {
   [Display(Name = "Type is expression.")]  
   EXPRESSION = 0,
   [Display(Name = "Type is operator.")]  
   OPERATOR = 1
}    

public class TmpParent
{            
   [Display(
     ShortName = "Company", 
     Name = "Company Name", 
     Description = "The amount of currently available product", 
     AutoGenerateFilter = false)
   ]
  public string str1 { get; set; }
  [DataType(DataType.Text), StringLength(20, MinimumLength = 3)]
  public string str2 { get; set; }
  public bool bool1 { get; set; }
  public TypeEnum enum1 { get; set; }
  [DisplayFormat(DataFormatString = "MMMM/yyyy")]
  public DateTime date1 { get; set; }
  [DisplayFormat(DataFormatString = "p", ApplyFormatInEditMode = true)]
  public float value1 {  get; set; }
  [DataType(DataType.Currency), Range(200, 5000), Required]    
  public float value2 { get; set; }
        
   public TmpParent( string _s1, string _s2, bool _b, TypeEnum _enum = TypeEnum.EXPRESSION )
   {
     str1 = _s1;
     str2 = _s2;
     bool1 = _b;
     enum1 = _enum;
     date1 = DateTime.Now;
     value1 = 100.1f;
     value2 = 300.5f;
   }
}
Grid fillings:
var p = new TmpParent( "A", "A", true );
list.Add( p );
list.Add( new TmpParent( "B", "B", false, TypeEnum.OPERATOR ) );
list.Add( new TmpParent( "C", "C", true ) );
list.Add( new TmpParent( "D", "D", false ) );

gridParent.DataSource = list;

c# - How convert string array into one string

If you use this code on string array:
string[] args = Environment.GetCommandLineArgs();      
Console.Write( args.ToString() );
you will get:
System.String[]
But better way in this case is to use string.Join() function (where you can set used delimiter):
string[] args = Environment.GetCommandLineArgs();      
Console.Write( string.Join( ",", args ) );
Then:
C:\app.dll,layoutdir=C:/app/bin
