The Title pretty much says it all but to clarify more I have a page with private properties that are storing a credit card object and a shopping cart object in viewstate so I can maintain a reference to them across postbacks. BTW the page involved will be using ssl. Is this safe?

How i can store value to ViewState?
EDIT: ViewState does not change when browser is refreshed, so even if you write to viewstate it will not save the data. i am trying to store a Queue in a viewstate (to track postbacks and refreshes to stop a form from resubmitting). The Queue is only saving with a count of 1 (the first item that is added to it) no matter how many items i add.
// New Queue of strings
private Queue<string> sTemp;
private Queue<string> p_tempQue
{
set
{
ViewState["sTemp"] = value;
}
get
{
return (Queue<string>)ViewState["sTemp"];
}
}
//BasePage constructor
public BasePage()
{
//create a Queue of string
//sTemp = new Queue<string>();
this.Load += new EventHandler(this.Page_Load);
this.Init += new EventHandler(this.Page_Init);
}
//In the 'page_Init' event we have created a simple hidden field by name 'hdnGuid' which is attached to the page on the first hit itself.
protected void Page_Init(object sender, EventArgs e)
{
//initializing the hidden field
//create a hidden field with a ID
HiddenField hdnGuid = new HiddenField();
hdnGuid.ID = "hdnGuid";
//if it is the first time the page is loaded, create a new guid and assign it as the hidden field value
if (!Page.IsPostBack)
hdnGuid.Value = Guid.NewGuid().ToString();
//add the hidden field to the page
Page.Form.Controls.Add(hdnGuid);
}
//In the 'page_Load' event we check if the hidden field value is same as the old value. In case the value is not same that means it's a 'postback'
//and if the value is same then its 'refresh'. As per situation we set the 'httpContent.Items["Refresh"]' value.
protected void Page_Load(object sender, EventArgs e)
{
if(p_tempQue != null)
sTemp = p_tempQue;
else
sTemp = new Queue<string>();
//The hdnGuid will be set the first time page is loaded, else the hdnGuid
//will be set after each time the form is submitted using javascript.
//assign the hidden field currently on the page for manipulation
HiddenField h1 = (HiddenField)(Page.Form.FindControl("hdnGuid"));
//create an instance of the GuidClass
GuidClass currentGuid = new GuidClass();
//set the GuidClass Guid property to the value of the hidden field
currentGuid.Guid = h1.Value;
//check to see if the Queue of strings contains the string which is the current Guid property of the GuidClass
//if the are equal, then the page was refreshed
if (sTemp.Contains<string>(currentGuid.Guid))
{
//adds item as key/value pair to share data between an System.Web.IHttpModule interface and an System.Web.IHttpHandler interface during an HTTP request.
System.Web.HttpContext.Current.Items.Add("IsRefresh", true);
}
//if they are not requal, the page is not refreshed
else
{
//if the current Guid property in the GuidClass is not null or not an empty string
//add the new Guid to the Queue
if (!(currentGuid.Guid.Equals(null) || currentGuid.Guid.Equals("")))
sTemp.Enqueue(currentGuid.Guid);
System.Web.HttpContext.Current.Items.Add("IsRefresh", false);
}
p_tempQue = sTemp;
}
I want to store some byte[] to ViewState. For example I want to store a list of FileBytes. How can I do it?

View 2 RepliesI am having tough time finding out this reason. I have a web control where i add some variable in viewstate. like viewstate["test"] = "1".

I have an ASP.Net site that has master pages. The master page has some calls to functions to get information from a database. Then in one of the parts of the master page I have form that modifies that information. So when the user clicks a button the information in the database is updated but the display of that information doesn't update until the page is refreshed or another link is followed.
I would like to know how to force a page to refresh without loosing VIEWSTATE information so that the newly updated data in the database will appear correctly on the screen.
