I am trying to add a fileupload control to my aspx page so the user can add pictures, but when I am implementing the code behind on VB the fileuploader controler is not recognized. I have this on aspx page inside a formview:

I'm using a FileUpload control in a website which should only be able to upload images. To that end, I'm checking its MIME type before accepting the upload.Does anyone know whether the FileUpload.PostedFile.ContentType property comes from the file itself or the request? The latter is insecure, since the request can be spoofed. If that's the case, does anyone know a good way to validate a file securely?

I know it's not just something completely pooched, because I created a new project with this code in it and that uploaded the file.[code]If I go select a file, then click the submit button, once the execution makes it to checkForm, Directory.FileName is "" and Directory.HasFile is False..[code]

View 1 RepliesHow do i add my javascript file as an embeded resource to the page after the ajax javascript already on the page? NB want to do this part dynamically to have code wrapped up in usercontrol.
in aspx page: scriptmanager
Code: Assembly: WebResource("Functions.js", "text/javascript")
Code: onPreRender:
ScriptManager.RegisterClientScriptResource(Me.Page, Me.GetType().BaseType, "Functions.js")
This code successfully adds my javascript code to the page but not after the AJAX javascript and so not all of my functions work correctly.
I have a master page which contains everything that inherits it within a form. A page inheriting from it needs to run some javascript to act on a text field on a page. However, I can't seem to reference that text field through the javascript, since the form begins on the master page. The following line will come up bogus: document.form1.txtFindUser.value = blah.responseText; This is because form1 is defined on the master page, while txtFindUser is on the current page.
View 3 RepliesDoes anyone know why a Page_Load would be called twice on a page when requesting an aspx page?I am using .Net 2.0 with the new .net 1.1 compilation model installed. Whenever I request a page, the Page_Load on the aspx page appears to be called twice, so does the Page_Load on and user controls added to that page.

I have a User registration form. On that form the user supply all his contact details and he can upload a image with the normal file upload control in ASP.net.
This is my problem. If anything goes wrong on the page then i give the User a error message saying what he left out or what went wrong. But the page refresh when that does happen. NOW the link to the image the user selected is gone. NOW when the user fix his error he thinks that he is uploading a picture but he never did because when the page re loaded it removed the link to his image inside the file upload control.
Note, the user don't have to upload a image, so there will be no error when the field is blank.

I have an aspx page with three web controls: one to control the List Users page, one to control the Edit Users page, and one to control the Add User page. I have discovered a method for accessing these elements, but it seems to be limited. Here is what I have done:
Protected Sub editUser(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewEditEventArgs)
'set selected user from gridview.

This works in most cases. However, I am unable to access the "enabled" attribute of these web controls. Why is this, and how might I access that attribute?
I am trying to check all the checkboxes on a webform (aspx) page, which is inside a master page,depending on the ID of the checkbox. The checkboxes are created dynamically, so I only know the prefix for finding it. So, I need to find these checkboxes by iterating the controls on the page somehow. It's not working out.

I have a parent page and child page, both aspx. All is working, but now I would like to close child page, if user leaves child popup page and goes back to parent page and clicks on something else like page index of Gridview. I CANNOT close popup child page if user goes to another app, or some other location, I only want to close if something on parent page is changed.
I have the PageIndexChange Event set up for other purposes, I would just like to add some functionality, perhaps a script manager to close the child popup page if the Gridview index is changed, java or another way which ever works best.I think I might also need to check if the child page is even open.

View 3 RepliesFirst off I'm using aspx pages with Visual Basic .net 2008 for the code behind.
I'm using a FileUpload control on an aspx web page to upload files to the server.
When I click on the Browse button I get a dialog box to select the file. I select the file and click the Open button and the entire file path populates the textbox portion of the control, just as it should.
However, when I use the same process to select a second file, after clicking the Open button it takes over 2 minutes for it to populate the textbox portion.
For some reason when the user click on the submit button and he re-fresh the page the same data get's uploaded again to my SQL Server 2005 database. I do not what this to happen... I am making use of a SQL Data Source!
