How to assign a textbox.text value to selected dropdownlist value

[golyg]

I have a page where the user selects a product. I wish to then populate the textbox value with the selected ddl value to allow them to update the value if necessary.

Here's my code:

Protected Sub ddlProductFamilies_SelectedIndexChanged(sender As Object, e As EventArgs) Handles ddlProductFamilies.SelectedIndexChanged

        txbProductFamilyUp.Text = ddlProductFamilies.SelectedValue.ToString

End Sub

When I debug this, txbProductFamilyUp value appears to be assigned the ddlProductFamilies.SelectedValue but when I return to the page, the textbox is null.

Any ideas?

That will only work if you've explicitly set the dropdown value the same as the text. Try ddlProductFamilies.SelectedText

Also check if there is other code in the codebehind that would overwrite the value.
