AJAX :: Update Panel - Changed Image Not Loading?
Oct 28, 2010
I've got a working update panel which works fine when updating a label control, but I can't get it to work with an updated image (initial image loads fine - the problem is with the update). I think the problem maybe that the image name and location don't change, only the physical file. In other words, I've loaded the page, then updated the image (same name and location), but the image does not update with the label? Here's my code:

And the code behind:

Now whenever dropdownlist index change's on select, untill page loads complete data it should show mesage as "Loading.... in center and middle of the page and background should become bit transparent". And when page load completely with data then that background and message should get disappear.

I am using Ajax to update my UpdatePanel every 1 second and it is working perfectly with my gridview. However, when I placed a image into the UpdatePanel, which it supposed be changing and updated every 1 second, it does not update but the gridview does. Gridview is getting active changing data from the database without any problem. The image which I want to see the updating is the StreamImage.jpg. StreamImage.jpg is inside my local directory. It only updates when I hit the refresh button.
<asp:Content ID="Content4" ContentPlaceHolderID="ContentPlaceHolder2" Runat="Server">

I'm having a problem where users with a slow connection aren't getting my image feed properly.i'm sending them new images every second to a picturebox inside an Ajax Update panel, using an Ajax Timer.so if their connection is really slow, one image doesnt load fully before the next one comes in, so they never get the whole picture...And for people with a faster connection, I would like to increase the update rate, and currently I see no way of dynamically setting the update rate.

I tried this link to generate verification Image [URL] ..... It works fine.
But I'd like to put a button in page for regenerating captcha for example. When the image was unreadable for user.
So I put an updatepanel in page and this is my code:
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<tr> <td colspan="2">
<asp:Image ID="imCaptcha" ImageUrl="~/Captcha.ashx" runat="server" />
[Code] .....
Although the image changes but the whole page is refreshed. Whether this is due to incompatibilities httphandler and updatepanel?

We have two update panels on our webpage. Now first update panel is having button cancel. While second update panel is having a file upload control.
Now if the user uploads a file that is going to upload in about 2 mins, and in between, say after 30 seconds the user clicks the cancel button, the upload taking place in update panel 2 should stop.
How do we achieve this ?

I'm new to the world of Update Panels and i'm having a hard time figuring out how to use them properly.
I have a form that has a table(TABLE1)...and inside TABLE1 i am linking to a sql data source....at the bottom of the table i have a 'Add' button.
When the user clicks the add button...a modal popup appears (POPUP1) and inside the POPUP1 the user can click a link that can add a user...when the link button is clicked...a panel within POPUP1 is set to visible = true.
I have one update panel around the whole table and the add button...when i click add and then click the link to add a user....the modal popup disappears.
