You can only assign a string to the .Text property of a Textbox.

The answers given so far do not compile with Option Strict On.

You should use:

txtVendorFAX.Text = daPo.Tables("vendor").Rows(i).Item(3).ToString

You should also make sure you have Option Strict Turned On: http://www.codinghorror.com/blog/2005/08/option-strict-and-option-explicit-in-vbnet-2005.html

use .Text property of the textbox by using following code

txtVendorFAX.Text = daPo.Tables("vendor").Rows(i).Item(3)

a textbox is a Textbox, not a string. This is why you are getting the error Unable to cast object of type 'System.String' to type 'System.Windows.Forms.TextBox

Try this:

txtVendorFAX.Text = Convert.ToString(daPo.Tables("vendor").Rows(i).Item(3))

Try this instead:
