Convert your Candidate class into something like this:
public class Candidate : DependencyObject
{
//CandidateID Dependency Property
public int CandidateID
{
get { return (int)GetValue(CandidateIDProperty); }
set { SetValue(CandidateIDProperty, value); }
}
public static readonly DependencyProperty CandidateIDProperty =
DependencyProperty.Register("CandidateID", typeof(int), typeof(Candidate), new UIPropertyMetadata(0));
//RegisterNo Dependency Property
public int RegisterNo
{
get { return (int)GetValue(RegisterNoProperty); }
set { SetValue(RegisterNoProperty, value); }
}
public static readonly DependencyProperty RegisterNoProperty =
DependencyProperty.Register("RegisterNo", typeof(int), typeof(Candidate), new UIPropertyMetadata(0));
//CandidateName Dependency Property
public string CandidateName
{
get { return (string)GetValue(CandidateNameProperty); }
set { SetValue(CandidateNameProperty, value); }
}
public static readonly DependencyProperty CandidateNameProperty =
DependencyProperty.Register("CandidateName", typeof(string), typeof(Candidate), new UIPropertyMetadata(""));
//BooleanFlag Dependency Property
public bool BooleanFlag
{
get { return (bool)GetValue(BooleanFlagProperty); }
set { SetValue(BooleanFlagProperty, value); }
}
public static readonly DependencyProperty BooleanFlagProperty =
DependencyProperty.Register("BooleanFlag", typeof(bool), typeof(Candidate), new UIPropertyMetadata(false));
}
in MainWindow.xaml:
<DataGrid ItemsSource="{Binding CandidateList}">
<DataGrid.Columns>
<DataGridTextColumn Header="Id" Binding="{Binding CandidateID}"/>
<DataGridTextColumn Header="RegNr" Binding="{Binding RegisterNo}"/>
<DataGridTextColumn Header="Name" Binding="{Binding CandidateName}"/>
