Hi ,

I have already visited the given site,however my dropdown is loaded from database values,so I do not have the value to compare and the given example is for fixed values.if my database values are 1,2,3,4 .I have selected 2 then when I submit the page,it should show me the 2 as selected along with 1,3,4 as other options.

The answer IS there, but maybe not obvious to you. Some pseudo-code ...

Code ASP:

<%
iSel=Request.Form("ddlPriority")
%>
<select name="ddlPriority">
<%
DIM strPriority
DO WHILE NOT objRS.EOF
strPriority = objRS.Fields(0)
sSel=""
If strPriority=iSel Then sSel=" selected=""selected"""
%>
<option value="<%=strPriority%>"<%=sSel%>><%=strPriority%></option>
<%
objRS.MoveNext
Loop
 
objRS.Close
Set objRS = Nothing
%>
</select>

I could finally make the solution for this.Here it is

<%
Dim dstrSQL
Set objConn = Server.CreateObject("ADODB.Connection")
objConn.Open Application("conn")
Set oRs = Server.CreateObject("ADODB.Recordset")
dstrSQL="select Name from ProjectPriority order by Name"
oRs.Open dstrSQL, objConn, 1,3

WHILE NOT oRs.EOF
if request.QueryString("Postback") = "true" and oRs("Name") = request("dropdown_menu") then
prioritytypes = prioritytypes & "<option selected value=" & oRs("Name") & ">" & oRs("Name") & "</option>"
ELSE
prioritytypes = prioritytypes & "<option value=" & oRs("Name") & ">" & oRs("Name") & "</option>"
END IF
oRs.MoveNext
WEND

oRs.Close
objConn.Close
%>
<html><head><title>Dynamic Drop-Down Menu Example</title></head>
<body>
<form method="POST" action="preview.asp?Postback=true">
<p><select size="1" name="dropdown_menu">
<%=prioritytypes%>
</select></p>
<input type=submit value="submit"/>
</form>
</body>
</html>

selected="selected" is the correct HTML terminology (or in your case selected=""selected"", as you'd be using it inside a string) but yes, what you have done is fine. I would also ...

Dim prioritytypes
prioritytypes=""

... at the top to be syntactically correct and to preload the variable with an empty string.

Thank you Siteguru !! will add te dim prioritytypes and initialize with empty string :-)
