Binded Datagrid displays System.Data.Datarow as data

Question

Using VS2010 C#
Hi All,
I am having a really annoying issue which I know there's an easy fix for, but i cannot figure it out for the life of me. My goal is to copy info from an excel sheet to the datagrid. To achieve this, I am taking the clipboard and creating a datatable, and
from the datatable --> datagrid. I have finally got the datagrid to display the correct column names and number of rows, but the records are showing "System.Data.Row" instead of the row's ItemArray. I've debugged the datatable and the correct
info is right there in the ItemArray properties. Can someone please help me resolve this issue?
Thanks in Advance!!!
Here's my code:
private void button1_Click(object sender, RoutedEventArgs e)
string s = System.Windows.Clipboard.GetText();
string[] lines = s.Split('\n');
string[] columnsNames = lines[0].Split('\t');
lines = lines.Where(w => w != lines[0]).ToArray();
DataTable dt = new DataTable();
DataRow dr;
List<DataRow> list = new List<DataRow>();
foreach (string str in columnsNames)
dt.Columns.Add(str, typeof(string));
DataGridTextColumn dgtxcol = new DataGridTextColumn();
dgtxcol.Header = str;
dataGrid1.Columns.Add(dgtxcol);
dgtxcol.Binding = new Binding(".");
for (int row = 0; row < lines.Length; row++)
string[] rowInfo = lines[row].Split('\t');
dr = dt.NewRow();
for (int z = 0; z < rowInfo.Length; z++)
if (rowInfo[z].Contains('\r'))
rowInfo[z] = rowInfo[z].Replace('\r', ' ');
dr[columnsNames[z]] = rowInfo[z];
dt.Rows.Add(dr);
list = dt.AsEnumerable().ToList();
dataGrid1.ItemsSource = list;
string name = ((DataRow)dataGrid1.Items[0]).ToString();
private void dataGrid1_LoadingRow(object sender, DataGridRowEventArgs e)
e.Row.Header = (e.Row.GetIndex()+1).ToString();

Since the DataContext of a DataGridRow is an item in the DataGrid's IEnumerable<T> ItemsSource, you must specify the column name or property name of T to bind to for each column. "." just binds to the DataRow itself.
You must also remove the \r also from the column name. You can then set the ItemsSource property of the DataGrid to the DefaultView of the DataTable itself.
The following modified code seems to work fine for this sample data:
col1 col2
val1 val2
private void button1_Click(object sender, RoutedEventArgs e)
string s = System.Windows.Clipboard.GetText();
string[] lines = s.Split('\n');
string[] columnsNames = lines[0].Split('\t');
lines = lines.Where(w => w != lines[0]).ToArray();
DataTable dt = new DataTable();
List<DataRow> list = new List<DataRow>();
foreach (string str in columnsNames)
string name = str.Replace("\r", "");
dt.Columns.Add(name, typeof(string));
DataGridTextColumn dgtxcol = new DataGridTextColumn();
dgtxcol.Header = name;
dataGrid1.Columns.Add(dgtxcol);
dgtxcol.Binding = new Binding(name);
for (int row = 0; row < lines.Length; row++)
string[] rowInfo = lines[row].Split('\t');
DataRow dr = dt.NewRow();
for (int z = 0; z < rowInfo.Length; z++)
if (rowInfo[z].Contains('\r'))
rowInfo[z] = rowInfo[z].Replace('\r', ' ');
dr[z] = rowInfo[z];
dt.Rows.Add(dr);
dataGrid1.ItemsSource = dt.DefaultView;
string firstname = dt.Rows[0][0].ToString();
Hope that helps.
