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.

View 2 RepliesI have a very odd and disconcerning problem. Just recently a page where I have 1 textbox and a buttoon has ceased to work.
When I look at the post coming into the PageLoad, the pageType is "POST", but the Page.IsPostBack is false!! and the textbox (which had content) is empty.
I have stripped all AJAX script out, so I have a very vanilla page (in a master page) being served.

Using Vb.Net 2003 Asp.Net 1.1
I have a dynamic data bound drop down list, when the user selects thier selected item I have to use the autopostback feature.
Problem is: when the page comes back it is at the top of the page not where i have the control.
I don't really need it to focus back on the dropdownlist but to scroll to it, I want to do it in the code behind.
Any "New" ways to do it, I mean new as in code from like 2010 instead of old code from the early days.
I really don't want to use Page.Register new Script...... code if I can avoid it.
What would be cool is a ScrollToControl() Function for my code behind that worked but didn't register script.
I have a textbox that is used for searching. upon clicking the ok button and posting back, the function is called, and gets matching results by using sql query in the aspx.cs file this information will be displayed in the div tag and set visible. initially div tag will not be visible. after the button posts back, then the div tag will be set visible.
View 1 RepliesI have a user registration form. Here I have link to another page (card info page) which has to be filled for the registration. User fills the few fields in the user registration form and click on the link that takes to card info page. When user clicks the link in card info page to navigate back to registration page, the previous details entered in registration got vanished. So I need to redirect from card info page to registration page without postback. How can i accomplish that?Response.Redirect() is used for redirection.

I am using Attributes.Add("style","color:green") with some checkboxlists and radiobuttonlists. When I click one of the checkboxes and I do the autopostback the attributes clear out. So I would think someone already has a sub to fix this. Something like:
SaveAttributes(checkboxlist1) or SaveAttributes() 'which would loop though all controls and save the state.
and then on pageload it would have
LoadAttributes(checkboxlist1) or LoadAttributes() 'which would loop through all controls and restore the state.

I have a website installed on one of our sales guys laptops and am having issues with the website hanging if left for 2 minutes. This doesn't happen on my dev box, my live machine or the other sales guys machine.
The website will hang. It's not just limited to this page, it will happen on all pages when I leave it for more than 2 minutes and then try and process a page that calls back via button or drop down ect. I have checked the IIS settings of the machine and everything seems the same as the other sales guys machine who is running the same version of the site.
Here are the specs:
Dev Box: asp.net 2, windows server 2008 64bit
Live Box: asp.net 2, windows server 2008 64bit
Working Sales Guy: asp.net2 windows 7 64bit
Broken Sales Guy: asp.net 2 Windows vista 32 bit (the only thing I can see different is windows version)
EDIT: For more information, if I stop the website from trying to load while it hangs, clear my history for the last hour and then refresh, the page comes back fine.
EDIT2: I have just spat out some debug information and it seems it doesn't even go into the post back I need.
EDIT3: This doesn't seem to happen when using Chrome but does when using IE and Mozilla.

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.
I am using jQuery tabs and an ASP.NET listview to display and edit some information. My problem is that when a user inserts a new record in one of the listview items my jQuery tabs go back to the first tab. Is there a way to keep track of which tab I am on or keep it from resting on post back?
