Hello!

I'm new to WPF, but as life goes, I have to bind to a ObservableCollection of Business Objects to a RadGridView in Code Behind, because the number of GridViewDataColumns is dynamic. Here I have an example (in my real application, my business class contains fields for sales data and the radgridview should be able to show a different number of sales periods).

Example:
=======

Business Object:
----------------------
public class Person : INotifyPropertyChanged
{
    private string _Firstname;
    private string _Lastname;
    
    public evebt PropertyChangedEventHandler PropertyChanged;

    public string Firstname
    {
        get { return _Firstname; }
        set 
        {
            _Firstname = value;
            OnPropertyChanged("_Firstname");
        }
    }

    public string Lastname
     {
         get { return _Lastname; }
         set 
         {
             _Lastname = value;
             OnPropertyChanged("_Lastname");
         }
     }

    protected void OnPropertyChanged(string strPropName) 
     { 
         PropertyChangedEventHandler handler = PropertyChanged; 
         if (handler != null) 
         { 
             handler(this, new PropertyChangedEventArgs(strPropName)); 
         }     
     }
  
}

ObservableCollection:
-----------------------------

public class Persons : ObservableCollection<Person>
{
    public Persons() : base()
    {
    }
}

ExamplePage:
-------------------
public partial class ExamplePage:Page
{
    
    Persons _p;

    public ExamplePage()
    {
        InitializeComponent();
        //Pseudo-Code: the ObservableCollection ist filled up in the DAL
        _p = DAL.GetPersons();

        //How or what is the way of binding the ObservableCollection to the radgridview1??
        //Possibility 1:
        radgridview1.DataContext = _p;
        //Possibility 2:        
        radgridview1.ItemsSource= _p;
        //Possibility ...: anything else?

        GridViewDataColumn colFirstname = new GridViewDataColumn();
        colFirstname.Header = "Firstname";
        colFirstname.UniqueName = "cFirstname";
        
        //I think, that here is the right place for column-bindung, but how?

        radgridview1.Columns.Add(colFirstname);        

        GridViewDataColumn colFirstname = new GridViewDataColumn();
        colLastname.Header = "Lastname";
        colLastname.UniqueName = "cLastname";
 
        //I think, that here is the right place for column-bindung, but how?

        radgridview1.Columns.Add(colLastname);   

    }
}

Please help me!

Kind regards

key: WPF, RadRichTextBox, RadDocument

I did the following steps to print merged RadDocument but it does not print and calling Print method hangs on forever. I had to kill the process.  Printing 1 Document works fine but same issue happens when I try to print 2 merged documents.

1. I am merging a list of RadDocuments  in to one RadDocument using methods answered in this forum.       
2. Then setting RadRichTextBox’s  document to the above created merged RadDocument.
3. Then printing using RadRichTextBox’s print method. radRichTextBox.Print("richtextbox", PrintMode.Native)

FYI, for Part 1) I did try this:
    foreach(var document in radDocuments)
    {
        mergedDocument.CaretPosition.MoveToLastPositionInDocument();

        mergedDocument.InsertInline(new Telerik.Windows.Documents.Model.Span(FormattingSymbolLayoutBox.PAGE_BREAK));

        mergedDocument.InsertFragment(new DocumentFragment(document));

}

and also  this:
 RadDocument mergedDocument = new RadDocument();
 foreach (RadDocument document in documents)
 {
     foreach (Section section in document.Sections)     {
         Section copySection = section.CreateDeepCopy() as Section;
         document.Sections.Remove(section);
         mergedDocument.Sections.Add(copySection);
     }
 }

Am i merging RadDocuments correctly? What could be the issue?
If this is a known Issue, then whats the best way to Merge and Print RadDocuments?

By the way : Document 1 had 7 pages and Document had 4 pages with 4 images total. It seems that as soon as I merge it does not print.

Hello!

I have many expression columns in my grid.

In the RowLoaded-Event I want th check, if the result of the expression is lower than 0. If yes, the text (forecast) color should be set to red.
How can I access the result of the expression?


I tried different things, but I'm not able to get the value for checking.

What I'm doing wrong? Please help.

Kind regards

Thanks
