WPF toolkit datagrid usage; WPF datagrid column size;

The datagrid for old WPF (from Visual Studio 2008) is available as an addon from WPF toolkit project. WPF toolkit is available here. Source code for this example is available here. In this example one creates a class holding data in the grid (GridRow). Instances of this class are held in an ObservableCollection. It has to be ObservableCollection because only then changes in the collection will be reflected in the grid. You could use a simple List but the Grid will not update new information then.

Later on you set the grid’s ItemsSource as the ObservableCollection created earlier on.

 

        In XAML file:
       
    <dg:DataGrid AutoGenerateColumns="True"  Height="433" Name="dataGrid1" Width="809" Canvas.Left="4.999" Canvas.Top="55"  Margin="5" SelectionChanged="dataGrid1_SelectionChanged" AutoGeneratedColumns="dataGrid1_AutoGeneratedColumns">
        </dg:DataGrid>
       
       
        In cs file:
       
        public class GridRow
        {
            public string Nr { get; set; }

            public string Lp { get; set; }

            public string Name { get; set; }

        }
       
        public static ObservableCollection<GridRow> GetSampleCustomerList()
        {
            ObservableCollection<GridRow> aaaa = new ObservableCollection<GridRow>();
            GridRow gr = new GridRow();
            gr.Nr = "10345";
            gr.Lp = "1";
            gr.Name = "Janina";
            aaaa.Add(gr);
        }
       
        private void constructDataGrid()
        {
            dataGrid1.ItemsSource = GetSampleCustomerList();
        }
       
        private void dataGrid1_AutoGeneratedColumns(object sender, EventArgs e)
        {
            dataGrid1.Columns[0].Width = 55; //Nr
            dataGrid1.Columns[1].Width = 46; //Lp
            dataGrid1.Columns[2].Width = 140; //Name
        }
