1) Currently, how are you trying to access the city values?
2) Can you show the markup for the city dropdown?
3) What is the error you are getting?

Thanks for the reply:
1)This code is of AjaxServerPage.aspx.vb
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim strSelectedItem As String = Request("selectedItem")
Dim lngId As Long
Dim strSql As String = ""
Dim oDT As Data.DataTable
Dim objDB As New CDataBase
'
If Not IsNothing(strSelectedItem) Then
lngId = IIf(Len(strSelectedItem) = 2, Right(strSelectedItem, 1), Right(strSelectedItem, 2))
If Left(strSelectedItem, 1) = "C" Then
strSql = "Select * from StateMaster where countryid = " & lngId
Else
strSql = "Select * from CountyMaster where stateid = " & lngId
End If
Else
lngId = 0
Exit Sub
End If
strSql = strSql & " And IsActive = 1"
'
Dim strTemp As String = ""
oDT = objDB.ExecuteDatatable(strSql)
With oDT
If .Rows.Count > 0 Then
strTemp = "<Select>,0/"
For i As Integer = 0 To .Rows.Count - 1
strTemp = strTemp & .Rows(i).Item(2) & "," & .Rows(i).Item(0) & "/"
Next
End If
End With
'
Response.Clear()
Response.ContentType = "text/xml"

Response.Write(strTemp)
Response.End()

}
After selecting any state I am getting list cities in the city combo.But on my code behind page I am not getting the City Name and City ID.Folowing is the code:
Public Sub FillAllCombos()
Try
'Fill cmbState combo with all states
strSql = "Select StateID,StateName from StateMaster where IsActive = 1"
FillCombo(cmbState, strSql)
'Fill cmbContactType combo with Contact Type from MiscMaster
strSql = "Select MiscID,MiscName from MiscMaster where IsActive = 1 and MiscType='" & const_MISCTYPE_CONTACTTYPE & "'"
FillCombo(cmbContactType, strSql)
Catch ex As Exception
End Try
End Sub
Please help me in the following problem.

Hi,
I gave u the code.I am using Ajax for this.I got this code from net.
Thanks...
|
|

|

The code is either not enough/not all the code.
Also, I get the feeling that you have not understood the code you are usng - so how do you plan to maintain it or even make it work? I may be wrong though.
Anyhow, goto to HTML Source view in the VS 2005 and find out the HTML markup for the city dropdown. Copy paste that markup here. In your code, where and how are you trying to access the city dtopdown values? that also needs to be shown to analyse this.

Well I understood the code.
I said my problem that I dont get the Id and name of the city on my codebehind page.How do I get that as i am getting the value through script.
Thanks....

I will try for the last time:
Can you post here the HTML/ASPX markup for the city dropdown?

If you're serious about learning this stuff, then I would suggest that you start by talking a look at http://www.asp.net/[^]. This site has some great tutorials and reference samples available.
As well as this, you will need to get a couple of good books on ADO.NET and ASP.NET (search Amazon and read the customer reviews).
I would also recommend that you take a look at more general issues in web development and buy books on XHTML and CSS.
Good luck.

The ASP.NET samples I am talking about are located here[^] and here[^].
The first one is a task by task walkthrough on how to accomplish different tasks in ASP.NET. The second are a set of Starter Kits that show "best practices" in development and offer you an opportunity to review and learn from other peoples designs/codes. This is how things like DotNetNuke came into being.

Dear all..
I have a login form, when I click the submit button, the code checks the users name and the password in the database if it is available, but it checks the password without its case(e.g.: the string "nour" is similar to the string "NOUR")
How can I control the password to be case sensitive?
Regards..

Hi,
One solution may be retriving the password from the db and check the password in the code level.

Hi,
int result = string.Compare(txtPwd.Text,strdbPwd,false);
Here false means accept case sensitive true means ignore case sensitive

Thanx alot baby

If you are using Sql Server, you could always cast the passwords to Varbinary and compare them.
SELECT ...
FROM UserList
WHERE UserName = @UserName AND
CAST(Password AS VARBINARY(30)) = CAST(@Password AS VARBINARY(30))
