I have two FileUpload button in my form which I put two custom validators. The issue is, when I click on first upload button, the second one also fires and says that it is required field or the similar message. Any idea what is going on?

I need to fire only those custom validator belonging to that particualr control. Here is the code:

<asp:FileUpload ID="MPNCPNFileUpload" runat="server" />
                   <asp:Button ID="MPNCPNFileUploadButton" runat="server" OnClick="TabFileUploadButton_Click"
                       Text="Upload" /></td></tr>
                   <tr><td><asp:CustomValidator ID="TabFileUploadErrorCustomValidator" runat="server" Display="Dynamic"
                       ErrorMessage="CustomValidator"
                       OnServerValidate="TabFileUploadedCustomValidator_ServerValidate">TextFile with MPN-CPN Details should
                       be uploaded</asp:CustomValidator>

<asp:FileUpload ID="DocumentFileUpload" runat="server" />
                    <asp:Button ID="DocumentUploadButton" runat="server" OnClick="DocumentUploadButton_Click" 
                        Text="Upload" /></td></tr>                 
                    <tr><td><asp:CustomValidator ID="DocumentUploadedCustomValidator" runat="server" Display="Dynamic"
                        ErrorMessage="CustomValidator" 
                        OnServerValidate="DocumentUploadedCustomValidator_ServerValidate">Document 
                    must be uploaded</asp:CustomValidator>

protected void TabFileUploadedCustomValidator_ServerValidate(object source, ServerValidateEventArgs args)
    {
        CustomValidator cv = (CustomValidator)source;
        args.IsValid = !String.IsNullOrEmpty(System.Convert.ToString(ViewState["PartsDetailFileName"]));
        
    }

protected void DocumentUploadedCustomValidator_ServerValidate(object source, ServerValidateEventArgs args)
    {
        CustomValidator cv = (CustomValidator)source;
        args.IsValid = !String.IsNullOrEmpty(System.Convert.ToString(ViewState["DocumentFileId"]));
    }

Hi meeram395,

Validation groups might solve your problem. So if you change the first button and the custom validator like so:

<asp:button id="MPNCPNFileUploadButton" runat="server" onclick="TabFileUploadButton_Click" text="Upload" validationgroup="ValGroup1" xmlns:asp="#unknown" />
<asp:customvalidator id="TabFileUploadErrorCustomValidator" runat="server" display="Dynamic" errormessage="CustomValidator" onservervalidate="TabFileUploadedCustomValidator_ServerValidate" validationgroup="ValGroup1" xmlns:asp="#unknown">
</asp:customvalidator>

and then for the second button and custom validator:

<asp:button id="DocumentUploadButton" runat="server" onclick="DocumentUploadButton_Click" text="Upload" validationgroup="ValGroup2" xmlns:asp="#unknown" />
asp:CustomValidator ID="DocumentUploadedCustomValidator" runat="server" Display="Dynamic" ErrorMessage="CustomValidator" OnServerValidate="DocumentUploadedCustomValidator_ServerValidate" ValidationGroup="ValGroup2">

So the first button will only validate ValGroup1 and the second button will only validate ValGroup2. I hope this helps.

So I need to make modification only in aspx page? There is no change in the code-behind? I mean no change in ServerValidate event?

No, you shouldn't need to change the code-behind.

To solve this issue, you can set "ValidationGroup" property of each control.

Try to set MPNCPNFileUpload, MPNCPNFileUploadButton and TabFileUploadErrorCustomValidator controls "ValidationGroup" property to "2" and

DocumentFileUpload, DocumentUploadButton and DocumentUploadedCustomValidator controls "ValidationGroup" property to "3".

hope this will help you. Cool | :cool:

There is a Property called ValidationGroup.
Using this property should solve your problem.

Below is a sample:

<asp:fileupload id="MPNCPNFileUpload" runat="server" validationgroup="ValGrp1" xmlns:asp="#unknown">
<asp:button id="MPNCPNFileUploadButton" runat="server" onclick="TabFileUploadButton_Click" text="Upload" validationgroup="ValGrp1" xmlns:asp="#unknown">
<asp:customvalidator id="TabFileUploadErrorCustomValidator" runat="server" display="Dynamic" errormessage="CustomValidator" onservervalidate="TabFileUploadedCustomValidator_ServerValidate" validationgroup="ValGrp1" xmlns:asp="#unknown">
TextFile with MPN-CPN Details should be uploaded

hi guys,
i try to send a mail like this:

MailMessage mailMsg = new MailMessage();<br />
        mailMsg.From = new MailAddress("localhost", "Webmaster");<br />
        mailMsg.To.Add(new MailAddress("localhost", "Client guy"));<br />
        mailMsg.Subject = "Message Subject";<br />
        mailMsg.Body = msgBody;<br />
        mailMsg.IsBodyHtml = true;<br />
        mailMsg.Priority = MailPriority.High;<br />
<br />
        SmtpClient smtp = new SmtpClient("localhost");<br />
        smtp.Send(mailMsg);

but then i get this error:
<code>The specified string is not in the form required for an e-mail address.

The smtp has already been set up from IIS. i just want to test how to send mail on my local system. how do i do this?

This error means, there is something wrong with the email address you using. Make sure the email address is correct.

Oh didn't you notice, analogous to square roots, they recently introduced rectangular, circular, and diamond roots to determine the size of the corresponding shapes when given the area. Luc Pattyn[^]

MailMessage mail = new MailMessage();

mail.To.Add("demo@gmail.com");

mail.From = new System.Net.Mail.MailAddress("from@gmail.com");

mail.Subject = "Subject";

mail.Body = "hello, this is test mail";

mail.IsBodyHtml = true;

SmtpClient client = new SmtpClient(server name);

client.Credentials = new NetworkCredential("username", "password");

client.Send(mail);
Response.Write("send mail!");

If CDate(Session("DispDt")) > CType(txtDespDate.Text, Date) Then
lblMsg.Text = "Dispatch Date Must be Greater than " & MasterDispDt
txtDespDate.Text = ""
Exit Sub
End If

It is giving error as

Conversion from string "31-01-2009" to type 'Date' is not valid.

Please tell me What can be done.

verify what is coming in your date variable from database??

it will give error only in the case when date string is not valid for example..

sometimes with day instead of 02 comes only 2 when we assign it to a string and datetime conversion fucntion gives error here..... try to give valid date to string.

To convert a string to date, the date format should be MM/DD/YYYY OR MM/DD/YY.

Check how you are retriving the date values from database.

Conversion of date depends on your system's date and time setting. Probably computer assumes that 31 is month and 01 is day. Problem may be resolve by interchanging their positions like 01-31-2009, but it may appear when you deploy it to another system.

To prevent this error, write your date like 31-Jan-2009, this method will never fails cause the use of month name abbreviation. This is my regular practice and I have got no error since I use it in this format. Try and best of luck.

Be a part of solution, rather then be a part of problem
