Answer 1

If you want to:

1. keep AutoGenerateColumns="True" AND
2. keep the columns Width being automatically adjusted to the data from the DataTable rather then have the same width

you need to set "1*" to the last column only. Please:

1) Add the event handler to .xaml

2) Add the following code to .xaml.cs

    private void dataGrid_AutoGeneratedColumns(object sender, EventArgs e)
    {
        int i = ((DataGrid)sender).Columns.Count;
        DataGridColumn column = ((DataGrid)sender).Columns[i - 1];
        column.Width = new DataGridLength(1, DataGridLengthUnitType.Star);
    }
