I'm not even sure if PostBackUrl is the command that I want/need. Here is my situation:

In a form on webpage "A" I have a Label, a TextBox, and a LinkButton

I want users to be able to click the linkbutton, which takes them to webpage "B" so they can choose a classcode from a gridview table, I then want that ClassCode to go back into the TextBox on webpage "A"

Could somebody point me to an example of how to do this please?

Here is my Code So Far

findClassCode.aspx

    Sub ChangeTable_Click(ByVal Source As Object, ByVal E As EventArgs)
        Dim YouSelected As String
        YouSelected = "SELECT [code] as Code, [description]as Description FROM [ClassCodes] WHERE [classCodeType]=" & selectDD.SelectedValue.ToString & "ORDER BY [Description]"
        SqlDataSource2.SelectCommand = YouSelected
    End Sub
