I have a Grid which contains a field with a file upload control in it. The problem is if you go to update the grid and a validation fails the file is lost.Can someone please tell me how and where I could store the file during postbacks?Currently it is in a static field
View 1 RepliesI've got an ASP.NET webform with asp:TextBox and asp:RequiredFieldValidator at the bottom of the page. If client side validation fails on form submit - the page scrolls all the way up.
I'd like to maintain the scroll position on failed client-side validation.
I have the following user control:
[Code]....
This control is used multiple times on one aspx page. The issue is that each time an instance of the control is validated due to a text change any prior error messages are cleared from the validation summary. I want the validation summary to maintain prior error messages during the postback.
How to maintain log in text file about insidences happening in program , for seprate date wise.

I have an application whereby a user browses to an Ajax enabled page, sets up some filters, and then clicks on download report. When the user clicks on this button, they are redirected to a Download.aspx page, which builds up the report and appends it to the response as binary (the file may either be zip/pdf or excel). The issue I am having is that everytime the user goes to the page and hits the download button the warning message from IE pops up "To help protect your security internet explorer has blocked this site from download files to your computer". This is not a huge issue, but the problem is that when the user clicks this warning to accept the file, it reloads the page, and all my filters are lost, so the user has to set up all the filters to filter out the data they dont want and then re-download the file.
The interesting thing is that I thought I could track the filters using session variables, so that when the page reloads after accepting the warning message it could be restored, but IE for some reason is not loading the page in the way it should, and so the Page_Load method is never fired when IE reloads it after the user accepting the warning, so I cannot restore the filter settings on the page because I have no event to do it from!
I have searched and searched for a solution.. I have tried changing the mime headers - I am using content-disposition tag set to "attachment; filename=report.zip", I have tried changing the mime type descriptions to different things to see if I can avoid the warning but to no avail. I have tried using an iframe but couldnt quite get it to do what I want it to do, the page was still being refreshed..
I have a system that has several large objects that need to be built and populated each and every time, and these objects may be accessed quite often as well. As a strategy, caching would not be that good for me because there are potentially thousands of these objects which are fairly large. So I propose to serialize the objects to the file system and then deserialize it when I need those objects again. I have several classes that need this serialization functionality.
These objects change as well, so on the next access I check if there were any changes and then I grab only the changes and edit the object, and then reserialize the object.
My question is what is the best way to do this, since I have several classes ..
i have one grid and one button when i click on that button then it expand and showing another grid under the row of parent grid how to do that.
View 2 RepliesI was referring muddasar's one of the article for the validation. Below is my code and i am trying to validate the file upload selected file format on the submit button. I have 4 upload control and fu1 is mandatory field and others are not mandatory fields. Though i need to validate all the four uploads if the files have been selected. My full sample code is below for easy testing,
<asp:FileUpload runat="server" ID="fu1" />
<asp:Label ID="lblMessage1" runat="server"></asp:Label>
<asp:FileUpload runat="server" ID="fu2" />
<asp:Label ID="lblMessage2" runat="server"></asp:Label>
[code]...
I am doing slight mistake on the return to the main function. if i test indvidual function it works fine. whereas if i include the 4 functions in one function with the return statement, it's not validating. goes to to the server.
I am using one datalist control for uploading multiple images.I hv used one Asp:FileUplaod Control and one button in one itemtemplate.I am using reqired field validator and regular expression validator for file upload cntrl I am assigning validation group for both of them on ItemDataBound event of my datalist so that each upload cntrl hv same validaton group as required field and regular expression validator.Now what i want to do is - i want to show my error message in validation summary which is right at the top of the page.I want one know how to write javascript that will assign validation group of my control in datalist on which i click ?
View 1 RepliesI am using a telerik radgrid so there are around 5 columns each column edittemplate contains a control along with a required field validator and also a property called AllowMultiRowEdit is set to true so i am able to multiple rows in edit mode.
If any of the values are cleared the for multiple rows I want only those to be validated on update of that particular row.
So i implemented the Grids item data bound event find each and every validator along with the update button and set a unique validation group.
The above implementation most times but fails at some time. Is there any other way of going about this ?
I like how the "Html.ValidationMessageFor" and "Html.ValidationSummary" helpers work for validating textboxes, such as for required fields. Is there some way I can accomplish the same thing for a file input control? From the examples I've seen so far you cannot directly bind a file upload to your model, so I can't use the [Required] attribute that I am using for the textboxes.

View 8 RepliesIm 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 have a fileUpload User Control FileUploadControl.ascx containing asp.net fileupload control and a requiredfield validator.I have another usercontrol RenderingTemplate.ascx that contains two FileUploadControl.ascx.RenderingTemplate.ascx is on page RenderingTemplateDetails.aspx, this page has save and cancel button.Now My requirement is in case user selects a file in one fileupload control,he has to select in other as well. If he does not select any file,let postback happen. cannot use Requiredfieldvalidator as it fires for both. I tried adding onclientclick to page save button and check whether file upload has some text in it.but i didnot succedd.Now i want this functionality to be a part of control so that i dont have to recode it on every page. IS there any clientside event on usercontrol which fires when save button of page is clicked.

View 1 RepliesI 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.

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:

The file is validated using FluentValidation. So if the file is valid (Is CSV and less than 400 KB) then the ModelState is valid.
The problem is that if the ModelState is valid then I need to parse the file and here some errors can occur:

Can this be done?
I mean the ModelState was valid but sudenly it is not valid anymore.
