I have a page that the users get redirected to. On page load this page runs a bunch of code behind that and loads table. The processing could take a few seconds to minutes depending on how big a report is run. Is there any way to completely render the page before automaticly kicking off the code? I am trying to stay away from forcing the user to click on another button.
View 3 Replies I have a page that is mostly dynamically built in the page load of my VB.net code behind page.
The issue is that I made a change to the page and added a button that redirects to a secondary page. When the button is clicked there is a very noticeable lag until the button click event fires because the page is being rebuilt every time.
I had not wrapped the code in the load event in the If not ispostback.... because I have dynamic controls that the user interacts with and I need the page to be rebuilt when the user clicks them.
The dynamic controls are clickable table cells. I did some looking and I found that the RegisterPostBackControl. I thought this would be perfect but, it does not although I maybe using it incorrectly.
Here is the code flow.

View 3 RepliesI am using ASP.NET 2.0 with C#(No AJAX) in my project. In a particular web page, when the a button is clicked, some server intensive C# code runs before the same page is displayed again with the results. While code execution happens on the server in response to Button_Click event, a blank white page is shown to user on his browser in between post backs. How do i show a message in this case, that the processing is still going on and ask the user to wait? I have used javascript to show a message on page unload. But this message is also erased when the page is posted back to the server and the user sees a blank white page on his browser. How do i avoid this white page? Is there a way to show a message in the blank white page? How do i show a processing Message while the page is loading upon on Post Backs to the same Page.

View 2 RepliesI know everyone has heard this a million times, but I need help with the back button and the AJAX update panel.I essentially have a form, that has 5 fields:Vehicle Make (In update panel #1) Model (In update panel #1) Trim (In update panel #1) Ownership Status Zip Vehicle model gets populated depending on what you put in make, same with trim. Now once the user hits next, I do a response.redirect. When I hit the back button, the possible values, and the current index is wiped for Vehicle Make, Model, Trim. I cannot
figure out a way around this.I have read about that history management feature, but seems uselesss since I need to somehow update the make, model, and trim possible values. Isn't there any way for me to get these values in the viewstate before I post the page?
just wanna ask you something. My requirement is that I need to download a large file.So,at the web server, there are a lot of zip files are packeted and when user request a link to download the file, those packeted zipped files will be combined into one large file and download it. So, I have done all the others steps. what I want to know is when user clicked that download link, I pop up another web form and wanna show processing progress or loading icon while zipped files are unzipping. Because unzipping time may take around 3 to 5 minutes depends on file sizes. Now I called the unzip function at the page load event, but it does not appear anything until unzip function has finished. guide me in which event or what kind of mechanism or technology should I use to show icon at the UI while processing at back end code.
View 1 RepliesLooking for the best technique on handling or at least some documentation showing an example.
Starting Page
Gridview control withing an update panel (also various controls used for filtering NOT IN UPDATE PANEL)
Databinding does not happen during page load.
Databinding is initiated when update panel trigger (asp:Button object) is clicked
Hyperlink column is added to returned records
Hyperlink posts to a separate page for detail for record which the hyperlink was clicked.
Second Page
While navigating via the browser back button to previous page (which contained the update panel and gridview) only the (various controls used for filtering) have retained state. The gridview is not shown (which is how the page loads initially when starting) How can I retain the state of the Gridview and add a step in the browser history all together?

I have a ListView control that is inside of an update panel. I have a Button control that calls code behind when clicked and I have a trigger in the update panel that is triggered based on the click event of the button. The button that calls the code behind and inserts a record into the database works fine but I get a full page refresh and the ListView Data is not updated as expected. I then can go to another page, come back and the new data is there. I'm not sure what I missing. Please see the code below.
<asp:UpdatePanel ID="UpdatePanel1" runat="server" >
<ContentTemplate>
<asp:ListView ID="ListView2" runat="server" DataSourceID="sdsrcMessageComments" DataKeyNames="MessageId"

View 2 RepliesLoading image on every postback ...
I have three textbox say textbox1,textbox2,textbox3, and a button.
After user entering the values in the respective textbox, he will click button. It cause postback, that time i need to show loading image, until the value is inserted into the database.
On the whole the user should not feel that the page is postback every time when he click the button, instead of it i need to show loading image.
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 ?

The javascript is running everytime I click the button. However, even though my subroutine updates the session variable after clicking the button, I always get the same alert. In other words, the same javascript is run after postback, and it is not updated. I am positive that the session variable IS being changed.

View 5 RepliesBeing new to ASP.NET I have run into trouble building my own Whack-a-mole program. I think my problem comes from using Buttons, which by themselves send post backs to the server, making the software unusable. The looks are in place, making new buttons show up in the grid, in different places by random. However, when a button is pushed - the score doesn't change (which I feel is strange).
Not so strange is that the Button doesn't work since it sends post back to the server - reloading the UpdatePanel. I think I should use a different controller like the CheckBox and style it hard using CSS (which isn't a problem). Is this the correct way to go, or should I make use of JavaScript AJAX instead?
Note to self: This technique shouldn't be used in a public application since it put too much unwanted pressure on the web server.

I have a panel withitn an updatepanel with some buttons.
When one of the buttons is pressed, I'm updating a different update panel.
The problem is that when I click the button, nothing seems to happen.
If I click the button again , then I see the first update. If I click it again, I see the second update and so on..
