    Adrian Forbes shares a Combo and Textbox Example

     

    This has a combo with a number attached to it. Same as 2Combo1Textbox with just the secondary combo and textbox. Selecting a value in the combo will update the textbox with the associated number.


    Here is the code for this Example

    <!-- Author: Adrian Forbes -->
    <%
    strconn = "Driver={SQL Server};Description=sqldemo;SERVER=127.0.0.1;
    UID=LoginID;PWD=Password;DATABASE=Database_Name
    set conn = server.createobject("adodb.connection")
    conn.open strconn
    set objRS = createobject("ADODB.Recordset")
    objRS.Open "select ID, strParent, intValue from Parents", strconn
    if Request("cboPrimary") = "" then
    lPrimary = objRS("ID")
    else
    lPrimary = clng(Request("cboPrimary"))
    end if
    %>
    <form name=frmTest action="ComboTextboxLinked.asp" method=POST>
    <p>
    <select name=cboPrimary size=1 onChange="PopulateTextbox();">
    <%while not objRS.EOF
    lID = clng(objRS("ID"))%>
    <option value="<%=lID%>"<%if lPrimary = lID then Response.Write " SELECTED"%>>
    <%=objRS("strParent")%>
    <% objRS.MoveNext
    wend
    %>
    </select>&nbsp;&nbsp;&nbsp;<input type=TEXT name=txtValue>
    </p>
    <p>
    <input type=SUBMIT value="Select" id=SUBMIT1 name=SUBMIT1>
    </p>
    </form>
    <%
    objRS.MoveFirst
    while not objRS.EOF%>
    <input type=HIDDEN ID="intValue<%=objRS("ID")%>" value="<%=objRS("intValue")%>">
    <%objrs.MoveNext
    wend
    objRS.Close
    set objRS.ActiveConnection = nothing
    set objRS = nothing
    %>
    <script language=VBScript>
    sub window_onLoad
    PopulateTextbox
    end sub

    sub PopulateTextbox
    lID = document.frmTest.cboPrimary.value
    document.frmTest.txtValue.value = document.all("intValue" & lID).value
    end sub
    </script>
