I want my dropdownlistbox to show the new item just entered from the database once the user clicks the update(save) button. I exactly don't know what is the exact property or method for dropdownlistbox since im a beginner in .Net.

Here is my code to get a better understanding:

Sub SaveNewSubCat(sender as object,e as EventArgs)

Dim strConn as String = "Database=watal;server=Maxood;User id=sa;password=;"
        Dim objConn as New SqlConnection(strConn)
        Dim cmdInsertSubCat as New SqlCommand("sp_SaveNewSubCat",objConn)

        objConn.Open()
        cmdInsertSubCat.CommandType = CommandType.StoredProcedure

        cmdInsertSubCat.Parameters.Add("@SubCatName",txtNe wSubCat.Text)
        cmdInsertSubCat.Parameters.Add("@CatName",cboCat.S electedItem.Text)

        cmdInsertSubCat.ExecuteNonQuery()

        lblNewSubCat.Visible = "false"
        txtNewSubCat.text=""
        txtNewSubCat.Visible = "false"
    Else
        lblNewSubCat.Visible = "false"
        txtNewSubCat.text=""
        txtNewSubCat.Visible = "false"

    End If
End Sub

Could some tell me what to do here?

Two ways:

(*) Postback to the server Save the value to the database and rebind the dropdown.

(*) Add the new value using JavaScript options object and then use an XmlHttpRequest to save the new value to the database. Using option (2), a roundtrip can be avoided.
