I have an upload control inside a panel and I am wanting to restrict the file types. I have found the following regExp but I'm unsure where to put it?
ValidationExpression="^(([a-zA-Z]:)|(\{2}w+)$?)(\(w[w].*))(.doc|.PDF|.gif|.jpg)$"
Does this go into the 'ValidationGroup' within the upload button?
I have implemented a validation for the file upload control such that, only when some entry is made in the file upload control textbox, the Upload button will be enabled else it wil be disabled.
When I implemented this , the validation on the Upload button is not working. For the upload button I need to check certain fields are not empty. But I find that because of the above implementation, the validation function for this one is not working .
I just don't understand how this is done. I've gone through several questions here and from a few other websites.
Basically, a company will be adding process steps, and I want there to be a textbox with a button next to it that reads "Add another step." Once clicked, a new textbox will appear beneath the current one, and the button will be moved next to the new text box. What do I need to do?
i'm experiencing some weird problem and cannot find any solution on how to fix it.... i have this function where user can update their email address, password etc. i put all this into an accordion. all works perfectly fine until i added in some validation. the validation works fine to. the problem is, now none of my button works. as in it does not trigger any action..

How do I add maximum rows that can be added ?
Im trying to upload file (lets say .xls file) but i need to check if the file type is macth with it binary. for example we can renamefileA.mp3 as fileA.xls on our windows and upload it. i need to check this first. can anyone suggest me how to check this file type ?based from what I browse, I found that BInaryReading can do it. here is the code
[Code]....
this check correctly. BUT, once it returns TRUE (when FileA.xls is really an XLS file), the POSTED FILE content will be 0. and the upload went file (the SAVEAS works) , and the file copied to the specified directory. but the content is 0 and when i open it, it said that the file is corrupted.i think this is due to the BINARY READER. is that true ? because before above method called, i make a breakpoint and the POSTEDFILE content length is still 16kb. after the method called, its 0.
I hv taken 2 panels one for School transport detail , the other for Personal Transport detail.
The validation controls are different for the panels. When selecting 1st panel the other gets disable and on clicking Save button the error msg of 1st panel appears if not entering proper values. But when 2nd panel I am selecting and without entering any value clicking Save button it still giving error msg of 1st Panel yet it is disabled.
I have added a file upload control and tried to upload a image with image name...it was succesfull..
Now when i click Add More Photos....i want fileupload controls to be added...(without using JavaScript)
I'm doing a multiple file upload script that add flies to a listbox and afterward uplods them to folder.
Every thing goes fine, even under the size and a extension restrictions, but when I try to add an .exe file with 30MB I would expect the script to write a warning saying the file is over the size limit and as an extension that cannot be uploaded, instead it shows a Page Unavailable
I'd tried to troubleshoot with try/catch on the init event but it doesn´t reach that far, it seem's that the compilation stops with no explanation...or is there?
I have an application that lets the use upload a pdf, I wanted to put a limit on the size the pdf can be. If the user tried to upload something too big I wanted to display a message to the user. I am trying to use a custom validator where it checks the size of the file and if it is too big it will set the "IsValid" to false. Is this the correct way to go about doing this? Is there a better way? When I test it, everything works in IE 8 and FF, but it does not work in IE 7 and can't figure out why.Here is what I have so far, this is on my aspx page:

And this is the code behind:

Some time back i posted for help in uploading CSV file to DB. With the assistance of other members, i was able to set that up on a test page and got the functionality working.. Now project is coming to the end and need to take that code / logic and incorporate with our application. On certain forms, we need to allow the user to export / import via a CSV file.. So this question is muti part for each function.
#1 Export = Since each form is unique, how can i setup the page to export that forms data that is currently in the DB? (I've used this control before [URL] and worked great) for excel. This may work fine for exporting the data out of the db for the user.
#2 Import, if the above is used or some other solution to export the specific table data, is there anyway to validate that the csv file that is being uploaded contains all the columns and is in the correct order? I mean if they were to export the data, but come back few days later to import it, and didnt realize that they selected a csv for another page or maybe they picked the right file, but while editing it they removed a comma or entered some data that would throw the format out of wack.. just looking for a way to read the selected file to import and compare to the table it is suppose to go into and make sure that the columns match and if possible, check for duplicates. I have read thru the forum and found ways to read the file into memory, set the data to a datatable or dataset and working with it that way.
So really looking for some good examples of being able to allow the export of data to .CSV and then allowing the data to be imported back into the table.(with validation in place before the import occurs)

How to use the asp file upload inside the update panel.
It works fine when it is place outside the update panel.
I have a panel (say, panel1) inside another panel (say, outer-panel)....The panel1 is visible only when a checkbox is checked in the outer-panel. I am using script manager, update panel and trigger to do this.
Now I have many text boxes in the panel1. I have to put a validation on all the boxes.
I tried to test this by putting validation on 2 boxes and this works fine on my local machine. When I put the same logic on the server, it does not. Of course the page on my local machine has fewer text boxes compared to the page on server. But I do not understand why the same logic works on my local machine and does not work on the server.
The page on the sever is a very long one and also it has a captcha control..... when ever I try not to enter text in one the text boxes which has validation and then hit submit...it redirects me to another page with out prompting for the validation error.
How do I add alert box or message-box in between the code in asp.net web application with c#. I am using updatepanel.

And here is where I add the Client Validation to the customer validator in the code behind.
[Code]....
The validation is if there is a value present in the first text box then the second text box is required.The page throws an error when the validation should fail, but if I ignore the error the validation works correctly.Do I need to move my javascript to the code behind as well?

View 1 RepliesI have a dynamic html table. I can create new rows by clicking 'add' button at runtime.
Each row has 3 textboxes and a fileupload control. A row can be submitted after filling the textboxes and browsing the file for upload.
A 'submit' button is there to submit a row(which will also upload the selected file).
If i select a row, fill it, choose a file to upload after browsing and click submit button, it works fine.
The problem is that if I fill a row (and not submit) and 'add' a new row, my previously selected file (filepath) disappears.
What can I do to keep the file path remain after adding new rows?
In the code behind based on a condition i want to add a error message to the Validation Control.
I tried the below.
'Call function to add error message.
protected void AddErrorToValidationSummary(string errorMessage)
{
CustomValidator custVal = new CustomValidator();
custVal.IsValid = false;
custVal.ErrorMessage = errorMessage;
custVal.EnableClientScript = false;
custVal.Display = ValidatorDisplay.None;
this.Page.Form.Controls.Add(custVal);
}
