This is my working code that shows how to start a resume and how to save it using asp.net mvc how do I tell that the file's The size is too large if the user submits a file that can not be operated. Right now, if a user submits a file too large, then they take them to an error page. I just want to do something on a popup or screen that asks them to submit a short file Thank you! 

  if (resume.File.ContentLength> gt; {string fileName = path. GetFileName (resume.File.FileName); String path = path. Combine (server.mappath ("~ / content / resume"), filename); Resume.File.SaveAs (Path); } TempData ["Notice"] = "Added resume:" + resume.File.FileName; See Return (Resume); } Hold (exception) {ViewBag.Message = "upload error"; See Return ("Upload"); }}

You can do it with a simple javascript:

< Pre> & lt; Script type = "text / javascript" & gt; $ ('# Image-file') ('Change', function () {var filesize = this.files [0]. Size / 1024/1024). Fix (2) + "MB"); // can now use the filesize variable and check it's price and show pop}}; & Lt; / Script & gt;

Or you can use it: 

  GetFileSize (fileid) function {try {var fileSize = 0; // If IE ($ .browser.msie) {// Before creating an object of ActiveXObject, please ensure that ActiveX is active in your IE browser objFSO = New ActiveXObject ("Scripting.FileSystemObject"); Var filePath = $ ("#" + fileid) [0]. value; Var objFile = objFSO.getFile (filePath); Var fileSize = objFile.size; // size in KB file size = file size / 1048576; // FF, Safari, Opera, and others other than {fileSize = $ ("#" + fileid) [0]). File [0]. Size // This will calculate the file size / put your warning or validation message here}} hold (e) {warning ("error:" + e); }}

Or you can submit the file size as: 

  & lt; Script type = "text / javascript" & gt; $ (Document) .ready (function () {$ ('# upload'). ('Click', function (e) {e.PreventDefault ()) var filesize = $ ("# file"). Files [0] .size / 1024/1024) .toFixed (2)); // File MB can now use the filesize variable and check it if the value and show pop (parciet (files)> 3) {warning ("file is too large"); Return false; } And {$ ("form"). Submit (); }}); }); & Lt; / Script & gt;

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ
