I want to change password. however, i am not sure because I did not use my side as a membership at all.

When the user types in the new password, this new password will be hashed upon clicking the button and saved into the database.
i have deployed my website on a particular server. i have some limitations in using viewstate and session variables. those pages in which i have used ViewState variables (for storing some information), i user accesses that page and does not do any activity for 5 minutes and if after 5 minutes he does any kind of activity (click on Link or button etc) then he receives following error: "Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster."
how i can avoid above error? another problem is with session. My session expires just after 2-3 minutes. What should i do for maintaining session for long time? i can not use cookies, as if user has disabled the cookies then my website will not work...

I have Dim a(15) as integer i wont to save this array in Viewstate .
View 2 RepliesI have searched the web for the answer and saw that mostly variables are saved in viewstate on page.prerender event. Then the value of the variable is set back in page load event.However, when I save a variable in viewstate on prerender or load events, how can viewstate store the value of the variable after it is changed dynamically on codebehind?
Let's say, after page is loaded, user clicked a button which changes the value of the variable in its onClick event. Then the postback event raised since the button was clicked. According to me, the new value should have been lost and cannot be saved in the viewstate if the variable is saved in the viewstate only in prerender event. Because on postback the prerender event wont fire and the value cannot be saved.
Shouldn't I save the variable in the viewstate just before the postback event rises?? If so, how can viewstate store the new value of the variable if the viewstate is saved in prerender event?
I set ASP.Net ViewState to off for a text box control, but the value for the name of the user is still there. Why is this so?
View 3 Replies At my user-control I populate listbox with collection and want save data in viewstatecontrolstate for further autopostback using.
protected void btFind_Click(object sender, EventArgs e)
{
var accounts = new AccountWrapper[2];

ListBox is populated at button click. When I save accounts to ViewState listBox is empty, when not it displays collection good.
i bind a DataTable to a gridview.i want to use the DataTable in some postback event, and ii want to use viewstate.

View 4 Replieshow save int array in viewstate?
View 4 RepliesI have a composite control that has a couple of private fields that reference values in the cache and these private fields are called during the constructor method. Since a string key is used to identify the value in the cache, I must have a way of storing that string key in such a way that it is available at the time the control is instantiated, and I have to be able to reference it on postbacks without it changing.
In addition, this key is generated the first time the control is loaded, but it should not be changed again after that first time.
How can I accomplish this?
I have already tried saving it to viewstate, but that doesn't work because viewstate is not yet available at the time the control is instantiated.
I have tried using a private field and then checking against Page.IsPostback in the constructor and if it isn't postback, I assign a value to the private field, but on subsequent postbacks it looses it's value, and I can't reassign it in the Page.IsPostBack again because it is an autogenerated GUID.
if user login first time in application in how i promot for change password in Asp.Net C#.
