I'm creating a web app using ASP.NET and AJAX. It was working fine till last week. Without anything obviously changed, it began loosing HttpContext between the "PageLoad" and Page Events of a dynamically added User Control. The main ASPX page has a placeholder to load the dynamic control. To avoid "View State Tree" errors, I add the pre PostBack User Control back into the placeholder in the "OnInit" event of the ASPX page, then remove it and add the new User Control in the "PageLoad" event. The code goes to the "PageLoad" event of the newly added User Control (uc1) (all is fine here), then it goes to the "PageLoad" of a User Control inside this first user control (uc2) (all is still fine here). Then the code goes back to whatever Event that was fired on uc1 (it is here where HttpContext is lost). Mind you that this setup was working fine since it's inception about one month ago. I have been tinkering with it all along and have not made any app-wide changes (to my recollection) that could create this effect. Anybody ever come accross this problem.
any help will be greatly appreciated.

Hi,
I have a button field in GridView. It shows the ID. When I click on it should grab the id and open new ASpx page based on that ID.
How can I do that.
Thanks in advance

You got to assign a property called command name!
So assign a command name to your button and write your logic accrdingly in the ItemCommand event!
if(e.commandname=="name")

while click the button you have to fire an event (you can call edit,delete ... command). In that function you can get the selected rows and you can process what ever you want.
Thanks

In my web page, I have a TreeView control. It databinds the image property on every node, however, the images I have are all different sizes, and I need them all to display 64x64 on the page.
Is there anything I can do short of manually resizing them with photoshop? I'd do that... but I don't have the time.

Hello Friends,
I am in a search of some information over asp.net. I have created a web application which my client requires to set in on a server which is phisically present in the company premises itself. The condition of the client is such that when the users are using the application in the same premise they should not be routed through internet, so the bandwith could be saved. Over there they should use LAN for processing the application. But for the user who is accessing the website through internet should hit the same server and application. So in short they need that the application should have two pointers.
I have tried giving it two pointers, the application is getting accessed through internet, user can login sucessfully but as the any activity is clicked it displays "Page Cannot be displayed" the reason is it is searching for internal server files through URL.
Eg...
My test application is deployed by name http://testsoft/login.aspx
My live application which has a public ip is by name http://255.26.235.22/login.aspx
When user logs in a web application internaly and clicks on any activity through LAN the application redirects the pages through the url http://testsoft/myactivity.aspx
But when user logs in a web application externally it should display ip http://255.26.235.22/myactivity.aspx but instead of that its getting redirected to http://testsoft/myactivity.aspx which is basically for internal users. So external users are not getting access through the activities of the application and the result which gets displayed is "Page cannot be displayed".
Is there any solution related to global.asax file ? If any kindly let me know.
Please reply ASAP,

The above code shows that you are using Absolute Path instead of relative path. Eg, You must use Response.Redirect("Login.aspx") where Login.aspx file is located in the same root not Response.Redirect("http://testsoft/login.aspx").

As per knowledge nope... But I have seen some application are frame the URL in Global.asa or Global.asax file. You check both scenario.

What exactly is it that you need help with? Opening the dialog box? Getting the file name from the dialog box? Using the file name in the code that reads the file?

ASP.NET is serverside. However, you have HtmlInputFile to lend you little help.

I have a concern on your reply to the spammer. When I visited his profile, he has signed only for posting spam messages. So I think we can just report spam/abuse and ignore.
When you reply to his message, an email would go to him with your email address also. He might be successful in that way harvesting email addresses for his spam database for further improving his spam venture.

No, he does NOT get my eamil address. He gets a message from CodeProject with my name on it. He never gets to see my email address, or anyone elses for that matter.

There seems to be widespread ignorance as to the nature of AJAX. AJAX is basically a way of using features build into the javascript language, the only thing you need is a browser with appropriate js support. ASP.NET has NO AJAX support, none at all. Microsoft has a .NET 2.0 only ( AFAIK ) library which makes it easy to offer AJAX without writing any code, but AJAX itself, is universal.

Don't use a DataReader, use a datatable or dataset to bind to the control. A datareader will remain open only as long as the database connection. In your case it is being closed almost immediately, which is good. However, using a datareader has the potential to remain open longer than it should, thus reducing the capacity of your site.
