passing values via URL

Hey,

Just a wee Q...I am trying to pass the value from my textbox via a URL and am unsure how to get this value.
My link reads:

Code:

<a href="AddSequence.aspx?RepNo=<%#txtRepNo.Text%>" style="COLOR: #0000ff">Add Sequence to this Rep</a>

but no luck! How can I pass this value?

Now, I am assuming you are using asp.net. So you just use a namevaluecollection object. The namevaluecollection is in the System.Collections.Specialized namespace:

Dim col As NameValueCollection = Request.QueryString

Dim RepNo As String = col.Get("RepNo").ToString()

Fraid I'm using VB.NET so I can't utilise the NameValueCollection.
Ordinarily the user clicks on the record from within a datagrid so it is easy to pass the RepNo value to the receiving page (AddSequence), however, the page I am trying to get the textbox value from is on a simple form (just used to display the actual record) and I don't really want to change how the page retrieves the RepNo value (i.e. Request.QueryString()).
There must be a way to get that value when the user clicks on the link and send it along with my URL, no?!

for any of you crazy cats who are looking to pass values via URL I found the simple solution by declaring a session variable in my VB e.g.

Code:

Session("repno") = RepNo

and then accessing that session variable from my HTML like so...

Code:

<a href="AddSequence.aspx?RepNo=<%=session("repno")%>" style="COLOR: #0000ff">Add Sequence to this Rep</a>

ahoy!

Be careful though. I think if the session variable doesn't exist yet, and you try to use it, it will through an error. The book I have says to check for a null value first. It is in C# though, don't know how VB.Net handles it.
