C# WPF Binding a text file to datagrid

Question

How can I bind a text file to a datagrid with C# WPF? The idea is to have a row in the text file to show as a row in datagrid.

I don't think you can bind text directly to a datagrid

What you can do however is bind an objet to a datagrid

create an objet representing your text file.

-- content --  
text1, param1, param2  
text2, param1, param2  

class OneLine{
  string text {get;set;}  
  string param { get;set; }
  ...
}

You can then bind those objects to the datagrid with a BindingList, which is mostly a List. The magic lies in the Properties of the object. The BindingList will try to get each property of the object and display them in the grid.

BindingList<OneLine> myList = new BindingList<OneLine>();
myList.Add(oneObject);

DataGrid myGrid = new DataGrid();
myGrid.DataSource = myList;

In my project I use the following approach

Create class that represent row in text file for example

public class cls_syslog_record
{
    public DateTime? f1 {get;set;}
    public string f2 {get;set;}                
    public string f3 {get;set;}
    public string f4 {get;set;}        
}

Create IEnumerable that used as source for DataGrid

public IEnumerable<cls_syslog_record> get_line_seq_text()
{
    cls_mvs_syslog_parser parser = new cls_mvs_syslog_parser();
    foreach (string record_line in File.ReadLines(this.filename))
    {
        cls_syslog_record text_record = parser.parse_syslog_text(record_line);
        if (text_record == null)
        {
             continue;
        }
        yield return text_record;
     }
}

set my IEnumerable object as source

static private DataGrid make_text_viewer(string p_filename)
{
    logger.Debug("start");
    DataGrid table_viewer;
    cls_file_line_seq fl_seq = new cls_file_line_seq(p_filename);
    table_viewer = new DataGrid();
    table_viewer.CanUserAddRows = false;
    table_viewer.CanUserDeleteRows = false;
    table_viewer.Columns.Add(create_column("Date Time", "timestamp"));
    table_viewer.Columns.Add(create_column("LPAR Name", "lpar_name"));
    table_viewer.Columns.Add(create_column("JOB ID", "job_id"));
    table_viewer.Columns.Add(create_column("Message", "message"));
    table_viewer.HeadersVisibility = DataGridHeadersVisibility.All;
    table_viewer.ItemsSource = fl_seq.get_line_seq_text();
    return table_viewer;
}

Then setup binding

static private DataGridColumn create_column(string header, string p_property_name)
{
    DataGridTextColumn column = new DataGridTextColumn();
    column.Header = header;
    column.Binding = new Binding(p_property_name);            
    return column;
}
