View 5 RepliesSession Variables Lost On Postback Using AJAX?
Jun 7, 2010I'm evaluating using Ajax in a new project and so I've developed a simple web page to test a few things, however even the simplest task seems to cause my session to be cleared. I am using VS2008 with .Net 3.5 SP1 and the page is in my existing solution which has several custom handlers and modules in the web.config. Below is the code I'm using, it's a simple test which puts a variable into the session then on the buttons postback tries to get the same variable, however it always fails as the session is blank.

<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server" /> [code]....
State Management :: Protect Variables On PostBack?
May 19, 2010I have a slight delemma that I have not been able to work out.
My Scenario is:
Page_Loads > Calls Sub Random Data Retrieved from a Table - Displayed on screen & Sets Variables from Row(0) for an Insert Statement > Click Button to Insert those Variables.(essentially, the Insert Statement Parameters are Dynamic in that they change each time the page loads)
The Problem I am having, is that each time the page loads, I need a New DataSet, and the Page_Load is operating too quickly, changing my variables on postBack and ultimately, inserting the new values that are now loaded.
How can I:
Page_Loads > Get and Set the Variables I need > Protect Those Variables from changing on the Next Postback (so the insert statement gets the values Iwant to insert but also set and get the next ones)?
If Not Page.IsPostBack Doesnt Work for me in my Page_Load because each time the page.loads, I need those new Random Variables from a DataSet
Someone had Mentioned ViewState, but I am uncertain how to use it. I just want to protect the variables so that it inserts properly
How To Access Variables Defined In Masterpage.master.vb
Feb 1, 2010I have a collection of cookies filled with Browserhawk information in masterpage.master.vb such as;

WCF / ASMX :: Access Session Variables Through A Web Service?
Mar 29, 2011In my ASP.net website we are going to use Silverlight to display some interactive diagrams. The users can add, edit and delete various diagrams on the silverlight front end. Silverlight will call Web Service methods to save the changes into the database. Besides the data being passed by silverlight to web service call, we also need to pass some data from the session (like logged on user id etc.) to the web service call.
My question is that how silverlight can access session data? I am trying to pass session information via a webservice method call over to Silverlight but, the session variables inside the web service methods are returning null value.
The Web Service is running under the same web root where the ASP.net website using Silverlight is also hosted. I have made EnableSession = True for web properties.
Store / Access - Application Wide Variables Or Globals In Asp.net
Feb 8, 2010What is the recommended or usual way an ASP.net web application(in C# language) can store/access values that are needed accross the various pages in a website. For example a basic company website might need the company's name and other related information available to multiple pages. Where do I declare these variables/values and how do I access them. Coming from c++ application programming I would usually store such data in a Singleton class object.

View 1 RepliesJavascript - Access Global Variables That Are Set Inside An Event Listener?
Dec 18, 2010I 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.
How To Access Any Server Side Events Or Variables In The Code Editor Window
Mar 1, 2010While working through some demos today I managed to trick VS 2008 somehow and I cannot access any server side events or variables in the code editor window. Hopefully
this screenshot will demonstrate exactly what I am missing. No matter what control I pick from my source I get the same drop down items overhead. What is quite weird is that when I drop new server side controls onto the source editor I can set the tag attributes for the events, but when I double click that event there is not an automatic created event handler with the same name created for me. Also, on the property pages there is no events image button (the one with the lightning bolt). The only property page items which have the events image button (lightning bolt) are the ajax toolkit controls. Already tried the "import all settings - VB Default" to blast away everything and no luck..
Are Content Web Forms Able To Access Variables Declared In The Code Behind Section Of It's Master Page
Dec 1, 2010I have a Master Page which controls the styling of my site. In the Code Behind, there are a few class instances instantiated as well as variables. These classes validate user access and then create user objects
I have a few Web Content Forms which carries out instructions based on the user objects. So far it seems that on each Web Content Form I have to create new instances of the classes found on the Master Page. This is doubling my work for every Web Content Form.
Is there anyway I can inhereit Classes and objects instantiated in the Master Page Code Behind?

View 2 RepliesC# - How To Access The Value Of A Checkbox Without A Postback
Jun 16, 2010I have a radgrid controlling access to an application for users. There are two columns, a 'name' column and a checkbox 'access' column representing their current access permission. the checkboxes are populated from a database. I would like the to change the checkboxes to grant or deny access to the users I specify. Since there are alot of users I would like to make multiple changes and use a submit button to write the changes to the database. I do not want to postback with each checkbox change and wait for the page to "blink". My problem is that with the checkbox postback disabled, when I click submit, the value of the checkboxes are not registering the changes I make. I need a way to access the current client-side state of the checkbox or some workaround to accomplish this.

View 2 RepliesC# - How To Access Control Text On Postback
Mar 2, 2011I'm making a site and throughout the site I haven't been very consistent with the way I get user input on postbacks. For example, say in a button event that takes two strings retrieved from textboxes and adds them together and outputs the string sum in a label:
protected void btnCalculate_Click(object sender, EventArgs e)
{
string text1 = textBox1.Text; //one way
string text2 = Request["textBox2"]; //the other way
lblSum.Text = text1+text2;
}
I imagine you would want to use Request[""] if the data has been posted to a new page, but for this situation, is one way preferred over another, and why?
