What I have is an asp page that users can enter batch numbers.  They need the ability to enter multiple batch numbers or just one batch number.  So my thought was to place a link button on the screen that when they click on it , it adds another textbox to enter another batch number.  Then the last part of the question would be how do I get an id of the textboxes to add back into the databases.

an easier approach (imo) would be to have users type in multiple batch numbers into one textbox, seperated by commas, spaces, semicolons (whatever really).  Then you could easily get all the values using:

TextBox.Text.Split();

It also would avoid any postback or limiting of amount of numbers you could enter like the multiple textbox approach may cause.  Or are you stuck on multiple boxes?

No not at all, enter in one place would be even better.  The thing that I guess I would need to more info on is the SQL insert statement.  We call out our connections from the common.vb so alls I have to do is a simple
Update  table  so on.
How would I go about updating a textbox described above using this insert method.
Thanks

This is the approach I would take:
string[] delimiters = new string[] { " ", ",", ";" };
string[] batches = txtBatches.Text.Split(delimiters, StringSplitOptions.RemoveEmptyEntries);
foreach (string s in batches)
    // insert into db
 
// your insert method would depend on how you access your DB
// Personally I like LINQ, but if youa re unfamiliar with that 
// I would say to go with the System.Data.SqlClient approach

Ok here is the code I wrote but I am getting a lot of blue underlines.
The first is it says string is a class type and so not a valid expression,  foreach is not declared,
most of it is not declared statements.

Private Sub lnkSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles lnkSubmit.Click

        string[] delimiters = new string[] { " ", ",", ";" };
        string[] batches = txtBatchNum.Text.Split(delimiters, StringSplitOptions.RemoveEmptyEntries)

        foreach (string s in batches)

        sql = "INSERT tblbatchNum (inTaskForceID, intUICid, strbatchNum) VALUES ('" & ddlTaskForce.SelectedValue & "', " _
                & "'" & DDLUIC.SelectedValue & "', '" & txtBatchNum.Text & "')"

        Response.Redirect("sadform.aspx")

    End Sub

Solution,
I added a link button that after they put in a number they press on link its saved moved intot a listbox so they can see it and then they can enter other numbers.  1. this allows them to see what they enter right away and 2. solves my problem of entering multiple numbers while giving error correction in teh textbox.
