TextBox.Databindings.Add() question.

Question

I have a dataset dsReceivedGoods. It has a table called dtPurchaseInvoice. I choose them as datasource for a datagrid so VS automatically creates two objects for it:

1. dtPurchaseInvoiceBindingSource
2. dtPurchaseInvoiceTableAdapter

There is a column dcInvoiceNumber which is a primary key for dtPurchaseInvoice.

I have a textbox on the form that I need to bind to this column. I Have tried the following but the value inside the datatable is always blank.

txtInvoiceNumber.DataBindings.Add("Text", dtPurchaseInvoiceBindingSource, "dcInvoiceNumber");

for dtPurchaseInvoiceBindingSource DataMember is : dtPurchaseInvoice and DataSource is dsRecieveGoods

I dont know what I am doing wrong here...

Thanks
