Good day.
How can I check in aspx whether or not the combobox is checked or not before the page gets posted back? I tried using a requiredFieldValidator, but apparently I cannot use that validation control with comboboxes?

You can write a custom validator in javascript.
By checked I assume you mean, a value has been selected. The best way IMO is for it to start with a default selection.

After you upload, you can use PostedFile.SaveAs wherein you can give a filename of your choice.

I have a crystal report which was running fine but now gives me an error about logon failed and it highlights the following line:
oStream = crpt28.ExportToStream(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat)
Here is the code I am using:
Imports System.Web.Security
Imports System.Data.SqlClient
Imports System.DateTime
Imports CrystalDecisions.CrystalReports.Engine
Imports CrystalDecisions.Shared
Dim crpt28 As CrystalReport28
Dim crpt28 As CrystalReport28
Dim myTable As CrystalDecisions.CrystalReports.Engine.Table
Dim myLogin As CrystalDecisions.Shared.TableLogOnInfo
Dim Param As SqlParameter
Dim SqlCom As SqlCommand
Dim sqlcon As New SqlConnection("Data Source=server;database=data;user id=user;password=pass")
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'Put user code to initialize the page here
crpt28 = New CrystalReport28
For Each myTable In crpt28.Database.Tables
myLogin = myTable.LogOnInfo
myLogin.ConnectionInfo.Password = "kris"
myLogin.ConnectionInfo.UserID = "kris"
myTable.ApplyLogOnInfo(myLogin)
Next
CrystalReportViewer1.ReportSource = crpt28
Dim oStream As New System.IO.MemoryStream
oStream = crpt28.ExportToStream(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat)
Response.Clear()
Response.Buffer = True
Response.ContentType = "application/pdf"
Try
Response.BinaryWrite(oStream.ToArray())
Response.End()
Catch err As Exception
Response.Write("< BR >")
Response.Write(err.Message.ToString)
End Try
crpt28.Close()
crpt28.Dispose()
crpt28 = Nothing
End Sub

Your db credentials that are being used are correct?

hi sanjubaba,
As we know asp:Menu control provide any level menu but it is not flexible to use directly becuase your menu will become static. If you want to change menu items than you have to change front-end. Hence it is better to use database driven menu using asp:Menu control.
Just check this link.

Hope this will help you.
Thanks & Regards

Hi,
I think that problem might be occured at the time when user enter any special tag like chararcter in textboxes like '<' or '>'.
So first you check with this possibility and write RequestValidate = "false" in Page directive.
But this attribute affects security of your site.
Regards,
Amar

First, thanks for the good hint  , the tag like characters generates an exception that I need to handle
But the old problem still not solved

We're using AJAX with an ASP.Net 2.0 site, and we've come across a problem.
We have a simple repeater control that contains a label, textbox, and checkbox. We've ajaxed out page and all is working well, except for this one little problem:
Our repeater controls are in their own update panel, and wheneven we check a checkbox in our repeater control, everything AFTER the updatepanel with our repeater controls in it, dissappears.
We've googled a ton and can't figure this one out. We would be thankful for any help.

Does your repeater make me.Context.Response calls? Me.Context does not always return the same object.

It turns out we had our FooterTemplate innpropriately formatted. (Ok, it was missing altogether).
By adding the FooterTemplate and a tag, it works properly now.
Thanks for your responses.

Hi to all
system.io.directory.createdirectory(Physicalpath) which crate directory in our local system.
when i host my code into server ,i want to create a folder in my local system directory.
i don't want to create directory in the server, i want to create file in local system. please understand my question and give good response
This is haneef.............................................................

You have a basic problem of understanding. Your C#/VB.NET code only ever runs on the server. For this reason, and many others, it's not possible to create a folder on the client side.
If you mean you want to create folders on the server, you cannot ever create them above the application root, that's another issue of security.
