On GridViewSelected Index Changed Event, Read the Selected Row in object of GridViewRow Class. Then Store the Object in Session and Access from Next Page.

Pass the value through URL as query string. In the second page, you can read this and display on the label.

Text box Format problem

Hi ,

i have used a Regular expression to validate the textbox to number format.

<asp:textbox id="TextBox5" runat="server" cssclass="InputField" tooltip="Enter Invoice Date (DD/MM/YYYY)" ontextchanged="TextBox5_TextChanged" maxlength="10" autopostback="True" >="">
<asp:regularexpressionvalidator id="regexpName" runat="server"
="" errormessage="This expression does not validate."
controltovalidate="TextBox5"
validationexpression="^\\d{1,4}(\\.\\d{1,3})?$" enableviewstate="true">;

i have one problem.
that is in textbox, if i enter 22.1 it has to become 22.10
or 22 it has become to format 22.00

protected void TextBox5_TextChanged(object sender, EventArgs e)
{
double a;
a = Convert.ToDouble(TextBox5.Text);

TextBox5.Text = String.Format("{0:f3}", a);
}

it changes the format but it does not validate then.
i.e it is been trigered after the validation.

i.e even if i enter 111111 it just appends zeroes like 111111.000 .

so is there any way i could do the validation and change the format after validation in the textbox.

thanks in advance.

This works as you expected. I assumed that you have set Textbox1.AutoPostBack = True; Even though the error has been captured by the validation control it doesn't causes validation for textbox. So TextBox5_TextChanged has been fired.

Make the TextBox's CausesValidation = "True". Its working fine as you expected and I have checked it. Please let us know if you find any problem.

if you use .net 2.0 or .net 3.5 you can use this .

hi,
i have tried using masked edit extender and maskedvalidating extender
but the problem here is it allows to enter in any location of the textbox .

i.e if input is 111111.10
no problem
but if input is 1_____.10
it gets converted to 1000000.10 automatically.

or if input is __12_.10
it gets converted 120.10

how can we solve this problem.or is there any other way we can have zeroes in decimal place always in the textbox while typing.

Thanks and regards,
sriharsha

Open file in their respective application

If you look this control is nothing but a DLL you can modify it as well. So modify this control or try to get a javascript functionality for this one.

Dear All,

I have an aspx page which contains link to different files created in different application such as .PDF, .doc, .txt, .xls etc.
My requirement is to open each type of files in their respective application window.
I tried System.Diagnostics.Process.Start method, but it does not works in client browser.

Please help, if any one knows how to handle it.

Give Link with each of the file. So that user can able to download file from there. When user will Click on the link he should get message with "Open" , "Save" , "Cancel" Button . Which is the common scenario of web application.

Thanks for the response. But it is opening the files in the browser window itself.
e.g., if I click on .doc file link, it should launch MS-Word and the file is to be opened in that application[assumed that MS-Office is already installed]. The same case is with MS-Excel, PDF[PDF reader installed] etc.

This is browser dependent and you have zero control over how it displays.

FileUploading gives error on Production Server

TextStrengthDescriptions can have 10 text descriptions at max. So you can change "very poor" string and instead you can show a status like "Not entered".

Hope that helps.

I have a fileupload control in my form for uploading PDF files. The issue is it is working fine in my local host and failing in production server. It is giving error that "Error Uploading File. The path is not of a legal form".

Following is my code:

protected void DocumentUploadButton_Click(object sender, EventArgs e)
    {        
       
        string errMsg = string.Empty;
        string PDFFilename = string.Empty;
        string PDFSaveLocation = string.Empty;

        if (DocumentFileUpload.HasFile)
        {
            string DocFileName = Path.GetFileName(DocumentFileUpload.PostedFile.FileName);
            string FileExtension = Path.GetExtension(DocumentFileUpload.PostedFile.FileName);

            string appPath = System.Web.HttpContext.Current.Request.ApplicationPath;
           

            if (!appPath.EndsWith("/", StringComparison.Ordinal))
            {
                appPath = String.Concat(appPath, "/");               
                PDFFilename = Path.GetFileName(DocumentFileUpload.PostedFile.FileName);
                ViewState["PDFFilename"] = PDFFilename;
                PDFSaveLocation = Server.MapPath(String.Concat(appPath, "/tmp/")) + PDFFilename;
                Label3.Text = "PDFFileName: " + PDFFilename;
                Label1.Text = "PDFLocation: " + PDFSaveLocation;
                DocumentFileUpload.PostedFile.SaveAs(PDFSaveLocation);
            }
            try
            {
                Guid g = AddFile(DocumentFileUpload.FileBytes, PDFFilename);
                ViewState["DocumentFileId"] = g;              
                File.Delete(PDFSaveLocation);

                DocumentUploadedCustomValidator.IsValid = true;
          
            }
            catch (Exception ex)
            {
                string strmsg = ex.Message;
                Label4.CssClass = "ErrorMessagesLabel";
                Label4.Text = "Error Uploading File. " + strmsg;
            }
}

Any idea what is the issue? Please help.I am not getting any head and tail of the issue since it is working fine in local system. It is not even printing the path and pdf file name.

I tried to get the path from where it is getting uploaded. For that purpose, I have adde a label control to print the path , Label1.Text = "PDFLocation: " + PDFSaveLocation;, But that itself, is not printing.
Even the the PDFFilename itself is not printing, Label3.Text = "PDFFileName: " + PDFFilename;

Make sure the Folder where you are uploading files is exists.
Now, There could be the issue with Folder Permission. In Local System, your .NET Application runs with ASP.NET Engine, which having the all kinds of permission that it can writes on your disk.
No, In Production when you have Hosted the sites on IIS Server, IIS run by default "Network Service" Identity, which having the minimum permission to read the files from server, NO Write Access.

Possible Resolution :

1. Give the Write Access Permission to Everyone for that Folder where you are uploading file.
2. Create a Separate Application Pool for you web application, Change the Identity of the Application pool to "Local System" which allows client to Write on your Server.

Hope This Will Help You Smile | :)

Thanks for your answer.

I am not getting the path of the production server even though I tried to print using a label control. So I think I will go for the second resolution. Can you please tell me how can I create the application pool? Any articles would suffice.
