Window have 2 text boxes ,one button and one Data grid view . when click button , data grid view need to display values of text box!

What I have tried:

private void btn_Click(object sender, RoutedEventArgs e)
{

DataTable dt = new DataTable();
dt.Columns.Add("id");
dt.Columns.Add("name");
DataRow dr = null;

if (dt.Rows.Count > 0)
{
dr = dt.NewRow();

dt.Rows.Add(txt1.Text, txt2.Text);
grid1.ItemsSource = dt.DefaultView;

}
}

In this case Data grid rows got updated , not adding values one by one!

Please anyone suggest a way to accomplish this in WPF!?

Thanks in Advance!

Hello,
Every time you are generating new object of DataTable in button click and then checking whether it contains any row or not . Obviously it does not contain any row. That's Why data is not showing .
First declare the Table globally means out side of button Click and define its columns
In button click event change the code by this way

DataRow dr =dt.NewRow();
dt.Rows.Add(txt1.Text, txt2.Text);
if (dt.Rows.Count > 0)
{
  grid1.ItemsSource =null;  //null the ItemSource just before you set the new value: 
  grid1.ItemsSource = dt.DefaultView;
}

Thanks
