It is a good practice to work on the underlying data source instead of modifying the data grid directly.
You have already created a data table so why not use it as the data source?

It should be something like this
C#

C#

DataTable dtBarcodes = blOrderDetails.getProductsonBarcode(Convert.ToString(tbbarcode.Text));
dgvTextiles.DataContext = dtBarcodes.DefaultView;

XAML

XML

<DataGrid Name="dgvTextiles" ItemsSource="{Binding}">

here dtbarcodes will give the values based on a particular barcode so dtbarcodes eventually changes according to corresponding barcode.

You don't specify the structure of the data table returned by getProductsonBarcode() and you don't specify what structure you want to present in the grid view, so it is not easy to give more specific advice.

Create a new data table then, with a static structure that can be shown in the grid and use that as a data source.
