I use asp file upload control to upload an image on my web application.
on its change event like this--
<asp:Image ID="Image1" runat="server" Width="77px" /> </td><td style="width: 350px; height: 8px"> <asp:FileUpload ID="FileUpload1" runat="server" onchange="if (confirm('Upload ' + this.value + '?')) this.form.submit();"/>
i dont want to refresh page while uploading an image.
I want to upload image through fileupload toolbox and display it in image control.
The image control should get the path from fileupload and should display the image.
I have done it with following code attached
HTML Markup-
<asp:FileUpload ID="FileUpload1" runat="server"
style="top: 256px; left: 533px; position: absolute; height: 23px; width: 217px" ForeColor="White" />
<asp:Button ID="btnset" runat="server" Font-Bold="False" Font-Names="Times New Roman" Font-Size="Medium" style="top: 309px; left: 605px; position: absolute; height: 26px; width: 81px" Text="Set Photo " />
<asp:Image ID="Image2" runat="server" style="top: 66px; left: 568px; position: absolute; height: 152px; width: 136px" BorderColor="#CCCCFF" BorderStyle="Ridge" />
VB Code-
Protected Sub btnset_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnset.Click
Image2.ImageUrl = FileUpload1.FileName
End Sub
I'm trying to allow the user to upload an image to the server (this part works) and display it on the next page (this part doesn't). I've got two files, imageuploadtext.aspx, which has the following code:
[Code]....
And the second file is imageloadtext.aspx, which has this short code:
[Code]....
As I said, the upload works fine and the file is received. But I can't get the source to display the correct image on the second page. Could it be to do with the fact the first page is VB and the second is C#? If so what code would I replace the C# with for it to work with VB? By the way, I'm currently getting a ";" expected on the image source line which I'm not sure where it goes, that might be it?
I have two controls, each placed in their own <div> and <UpdatePanel> on my form. I am having trouble getting the partial page postback to fire after the file upload has completed. I have not used the __doPostBack approach before so I'm not sure if I am heading in the right direction.

I have a dynamically generated image placed inside an update panel. The image is generated with the Generated Image control (see here for more:
[URL]. This is basically a specialised httphandler linked to a normal asp:image, where the image src is generated dynamically. In my case, I use some GDI+ to dynamically generate the image, based on values from a database query.
The problem I have is that the image does not update when the update panel updates. The image does, however, update if I manually reload/refresh the page (i.e., hit F5). Why is is that some code fires during an update panel update, and not other code? And, more importantly, what can I do to make sure the image generation code does fire during the updatepanel update?

View 1 RepliesI am using an updatepanel and a grid is placed within the same.Now,I have a checkbox corresponding to each row of the grid.If I check it,say corresponding to one row and click a button(placed outside the panel), a popup will be opened which is a separate aspx page having its own functionality.
The requirement is like I need only the panel to refresh not the whole page.
I have the following code so it'll show an animated progress GIF but if the site takes longer than this, it will quit. Is there a more effective way?

So I'm working on a site that is going to need a file upload control where the user would be able to upload an image, and then the page would postback causing the image to appear for their viewing (before they submit the data to the database, the image is being stored as type image). What I do now is have my own private web form where people send me their image, I format it accordingly and use the following simple code to upload it:
byte[] newimage = fileUpImgFile.FileBytes;
var myDataTable = (from item in context.TypeSet where item.Number == txtBxNumber.Text.Trim() select item).ToList();
foreach (Type item in myDataTable)
{
item.Photo = newimage;
}
context.SaveChanges();
Which works, but in this case, it would only work if the record exists already in the database so the person would have to save the data, then go back in and upload the image (inconvenient and inefficient). Is there a way to upload it, store it in memory, and then display it, without saving it to the database?

View 1 RepliesI'm posting this here because is related with ajax:
I need to upload files without the postback. So far i know that i can use an UpdatePanel with an AsyncFileUpload to achieve this, and it works fine, but this is not enough for me. Turns out that i need the fileupload control to be invisible until the user press a button. then i have to show the file upload control also without the postback, that's why i'm using the updatepanel. To acomplish this i'm using the following code:
[Code]....
if i don't use the normal panel it works fine, but when i put that control, it doesn't work. By "doesn't work" what i whant to say is that it doesn't fire the OnUploadedComplete method.
