The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Validation for Excel File while uploading file

Zones: Appletalk, C# Programming Language, Programming for ASP.NET

Tags: excel, file, validation, uploading

Hi,

I am working on Web Application using C#, ASP.Net2.0, MSSQL 2005

I need to upload the file, so I read the article from the MSDN

http://msdn2.microsoft.com/en-us/library/aa479405.aspx

Now I want to upload only Excel file.

So, from MSDN I got this kind of validation we can put

<asp:RegularExpressionValidator
id="RegularExpressionValidator1" runat="server"
ErrorMessage="Only mp3, m3u or mpeg files are allowed!"
ValidationExpression="^(([a-zA-Z]:)|(\\{2}\w+)\$?)(\\(\w[\w].*))
+(.mp3|.MP3|.mpeg|.MPEG|.m3u|.M3U)$"
ControlToValidate="FileUpload1"></asp:RegularExpressionValidator>

So, I changed the above code to as per my requirement as follows

<asp:RegularExpressionValidator
id="RegularExpressionValidator1" runat="server"
ErrorMessage="Only Excel (.xls) files are allowed!"
ValidationExpression="^(([a-zA-Z]:)|(\\{2}\w+)\$?)(\\(\w[\w].*))
+(.xls)$"
ControlToValidate="FileUpload1"></asp:RegularExpressionValidator>

I get the error
Only Excel (.xls) files are allowed!

But I am chossing Excel file only has the path

C:\dinesh\Projects\ProjectName\Documents\Sample MTOs EE108 (DWP-06-6100EK)(1).xls

Please help me in correcting RegularExpressionValidator

Many Thanks

Check it with server side:

fileExt = System.IO.Path.GetExtension(FileUpload1.FileName)

If (fileExt = ".mp3") Then

And see if it is the punctuation in your filename that is causing the problem.

Just filter the extensions

string ExcelFile;
string[] FindFiles = Directory.GetFiles("C:\\What_ever_Folder\\", "*.xls");
foreach (int ExcelFile in FindFiles) {
ComboBox1.Items.Add(ExcelFile);
}

Hi,

I tried the expression you have given but not worked

I mean I tried

([a-zA-Z-]:(\\w+)*\\[a-zA-Z0_9]+)?.xls

This is quite urgent for me. Or If you have some other way of doing it.

I want the validation to perform on client side and message to display on screen rather than javascript alert

Many Thanks

Please help me

Hi

this pattern i've just tested with the System.Text.RegularExpressions
and is valid

public bool IsValidExcelfile(string strIn)
{
string pattern = "[a-zA-Z0_9].*\\bxls\\b";
Regex expression = new Regex(pattern);
return expression.IsMatch(strIn);
}

Hi,

Thanks for your reply,

No it is not working

I wrote

<asp:RegularExpressionValidator
id="RegularExpressionValidator1" runat="server"
ErrorMessage="Only Excel (.xls) files are allowed!"
ValidationExpression="[a-zA-Z0_9].*\\bxls\\b"
ControlToValidate="FileUpload1"></asp:RegularExpressionValidator>

I have selected the path
D:\dinesh\Project\1\Documents\Sample MTOs EE108 (DEWP-06-6100EK)(1).xls

and I get the error message
Only Excel (.xls) files are allowed

This is a small validation thing which I want

Please help me in resolving this issue. If this way it is not resolving than guide me some other way use anything else

But not javascript alerts

Many Thanks

Try validate before displaying the error message.
Your above code will never reach the validation part.

<asp:textbox id="textbox1" runat="server"/>
<asp:RegularExpressionValidator id="valRegEx" runat="server"
ControlToValidate="textbox1"
ValidationExpression=".*@.*\..*"
ErrorMessage="* Your entry is not a valid e-mail address."
display="dynamic">*
</asp:RegularExpressionValidator>

Thanks vbturbo,

This works fine

Is it possible that we check the modified or created date of the file is current date at the cleint side.

I mean before uploading the file

Great.
