I am having fileupload control having its "multiple" attribute equals to "multiple". I am facing a weird issue in CHROME browser. The isse is that onchange event of file upload control is not firing for more than 12 files selected at once. The event is firing if I have 10 files selected at once. On FF and Safari it is working fine. Here is the code:
I need to get the name of the file the user selects from the input type file control and display it on to the page. The javascript onchange event does not work in ie 7 but works well in ie 8. The same is with the case in jquery change() function.
i want that when a user selects the file to upload then the text area of file upload control should get disabled,only the browse button should be enabled.i want to prevent the user to edit the path of the file upload control..
i have used file upload on one of my web page..the file path is not shown in google chrome..rest in all browser the path is shown..in google chrome only the file name is shown and not the whole path..i want the path to be shown in google chrome
I have to create a HtmlInputText control in code and while in code set it so that it will respond to text changes purely on the client side and not generate a server side event. In an aspx page this would be done like so:
I am having a DOB text box. This text box also allows to enter the date and also to pick the date using ajax CalendarExtender.
I used to set the dirty message when we edit some thing in the page.
When I enter some thing on the text box and click on the cancel button, dirty message will occur.
The problem i am facing is that, in Edit mode, I used to get all the records and assign to the text box. In that scenerio, the dirty message si automatically set since the DOB gets changes.
I need to get an image url using FileUpload Control. When i do it in the explorer it shows all files to select. But i need to show only ".jpg,.gif" files. How can i do it.
function btn_AddToList_Click() { var filePath = document.getElementById("FileUpload").value; if(filePath.length > 0) { var opt = new Option(filePath,filePath); var listBox = document.getElementById("ListBox"); listBox.options[listBox.options.length] = opt; } }
I am using the async file upload control to upload to a image file. I want the user to upload only jpg files. And for that I am checking the uploadedfile content type in server side, after the upload complets. I wanna check this, before upload starts. There is one javascript method
function startUpload(sender, args){}
but how to access the content type of the file selected by user.
I am using ASP.NET 2.0 and trying to use a simple Form to upload a file to a web service. I have the action attrib set to the url of my web service. However, in firefox, I can't see that it is making any call to that service at all. NOTE: I can throw int the below "Action" value to a browser minus the name of the web method and get a page showing the available web method so I believe the URL for the "Action" attribute is correct.
How can I see what is going on since I don't see any call be made. I am also of the opinion that this might not be the best approach. I am new to the entire web development space so I am trying to find better ways of handling problems.
I want to upload files to the web servers from the client machines.
Can i upload a file on a network share folder using file upload control?
I would like to create a share folder on a file server sitting next to the web server. If i upload the file from the network share folder instead of uploading it from the client machine does it make any difference?
Will the file be stored in a temporary location before copying to the final destination? Where will be the file stored in this case of uploading it from share folder?
My testers have discovered that if you type free text into a file upload input then none of the buttons on the page work until that text is removed (so the page cannot be submitted).
I am able to replicate this with the following ASPX code (with no code behind):
(Note that I haven't bound any handlers to the page; despite this, the page is submitted when the submit button is clicked only if no text is entered into the upload text box)
Is there any way to prevent users from typing free text into a file upload control? It seems that this is only possible in IE - Firefox and Chrome natively prevent text from being entered into upload input fields.
I've seen solutions elsewhere which suggest hiding input and replacing it with a label / button combo, but this seems like it might cause more problems and work inconsistently across browsers.
I'm using a slightly modified version of Valum's upload [github link], I've modified it to upload to a database but haven't modified the javascript that it is using to get the file into the Request as an InputStream. The following line of code is failing in IE 8 but is confirmed to work in Chrome. using (Image imgInput = Image.FromStream(Request.InputStream)) The error received is "Parameter not valid". It appears to be having an issue with the Input Stream being used but it exists/has data (not sure how to validate if the data is good or not).

i am trying to upload files through the ASP.NET File Upload control.
Every thing is working fine, except for the fact that when i try to upload the file on the server i am getting an error: (probably some authorization exception).
do i need to give some rights to the upload up there on the server. If so then for which account and do i need to restart the server after giving rights?
