Web Forms :: Global Variables, Menus And Post Back?
Jan 8, 2010
with a problem im having or at least give me an idea about which direction i should be going in.I have an asax file - with the following void Session_Start(object sender, EventArgs e)in that I am storing a session which holds a boolean.This boolean holds a flag which when set to true tells the application to go to the database and retrieve data, if its set to false, it checks the information in memory.I am using master pages and inside my master page i have and ascx files - which holds my navigation items(I build the navigation menu based on certain criteria)on a content page (a page that uses the master page) I perform a function when a button is clicked and I set the session flag to truethe problem is that the flag is not being checked until i refresh the page twice and therefore the menu is not updating until the user clicks to another page.my suspicion is that it is because of the page life cycle (the event handlers are done AFTER page load) - is there anyway around this?Is there any web page links you have got that I cant google? (yes i have googled but to little luck - maybe im using the wrong search term).on an additional note im trying to avoid like the plague - storing anything in the viewstate

Being 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.

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 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.
The pages is

For some reason it seems as though variables that I declare in javascript sometimes persist themselves across applications even when I do a response.redirect. I thought that a response.redirect would clear them out.

I'm using ListView + DataPager + ObjectDataSource mix.
In the implementation of my SelectMethod of an ObjectDataSource I'd like to access a global variable set in the PageLoad() event (the method will return just the proper number of items per page). Although the variable is initialized in PageLoad() it appears to be null in SelectMethod. How can I change that?

I have an app which has a form that used to use AutoPostBack rigged controls (dropdowns, radiobuttons etc.) in an updatepanel, and I used to set session values on each postback. I posted the form using PostBackUrl to an external page, using a bit of javascript OnClientClick to copy my data into meaningfully named hidden fields.
Now, I've had to rewrite the AutoPostBack-ing controls so that all the cascading dropdown work and date calculation etc. is done in JavaScript, and not in C# - no more postbacks, no more updatepanel.
This means I've lost the ability to set my session values on postback. Can anyone think of a solution for setting these before I post my form? I need to set the session variables, plus post (querystrings are not an option) to the external page with the values from my form - and actually send the user to the external page, too.

I am working with Google maps api V3. I need to get the values of the getSouthWest & getNorthEast bounds of my map. To do this the 'bounds_changed' event needs to be fired in order to get the new values. This is all good, however, I need to access these values from outside the event and passed to a server side function (more specifically, I don't want to call my server side function every time the map bounds are changed).
My code is:
//Global
var sw, nw, Searchbounds;
function myFunc(){
google.maps.event.addListener(map, 'bounds_changed', function() {
Searchbounds = map.getBounds();
sw = Searchbounds.getSouthWest();
ne = Searchbounds.getNorthEast();
});
CallServerSideWebService(sw.lat(), ne.lng(), ne.lat(), ne.lng());
}
When executing this code I get the error message sw is undefined.

I have a custom class that pulls user information from a SQL Server table. Now that I'm expanding the site from a single page to others. I want to shift the code to the Session_Start event so that the information is always loaded when the site is accessed. How do I call my custom code from global.asax since its script and not a class.

Beginner question:
I'm not sure if this is specific to Telerik's plug-in I'm trying to use or if it's a 'generic thing' I'm doing wrong ?
I have a RadTextBox:
<telerik:RadTextBox ID="RadTextBox1" Runat="server" name="nameTest"/>
And I have an ASP button that run this code:
Dim a As String = Request.Form("nameTest")
Dim b As String = Request.Form("RadTextBox1")
Both a and b always remain null.
Questions
- How do I get postback values from Rad/components ?
- How do I get postback values from Rad/components when they are in user control ?

1) The web application I'm building is a person enters information and the categories are selected by using checkboxes. The input page I have checkboxlist and it enters correctly has a one line to the database. For example, when they check one of the following Red, Blue, Orange and brown, they appear as one line in the database. When they do a search on the individual I need the checkboxes to return that they were selected when it returns information from the database so they update the information or deselect a color or something. Do I need a autopostback on the checkboxlist?
2) Is it possible to have a search page base on checkboxes. For example, the user checks red, and blue. Clicks on the search button. On a gridview every person who checked red and blue when they first entered information will appear in the gridview. Do I need a checkbox result table with a bit field?
I'm not sure which way I should go with this. Just asking for a direction in how I can do this.
