C# - View State Not Retaining Values?

Jan 7, 2011

I'm trying to retain "visible" property of a control using view state in the following way

public bool showstatusbox {
get { return Convert.ToBoolean(ViewState["statusbox"]); }
set { ViewState["statusbox"] = value; }
}

Is there anything I should do other than this to retain value. Because, though I store the value in view state, on postback, its becoming null.

State Management :: Session State Returning Null Values?

Apr 29, 2010

I have a clear button and a textbox in an aspx page. I set the session variable in this page as

String str = Textbox1.Text;

Session["TypeIds"] = str;

and I clear the sessions in a clear button event as

Session["TypeIds"]=null;.

Then when the user types some value in the textbox ,on Response.Redirect on another aspx page, the session variable returns null values.It does not retain its session state. The session state has to be maintained in the next page. Is it because this clear button event and setting explicitly to null creates this problem?

State Management :: Losing View State Upon Refresh?

May 13, 2010

I have two radio button list:

*1* report views -- 4 options -- NOT in updatepanel
*2* pagination views -- 2 options -- IS in updatepanel

The situation goes as follows: Refresh WORKS in default setting but when I select *2* radio button options and refresh the page renders the state that the (1) was entered in.

Example: () are the radio buttons
Report Viewing: () (x) () () Pagination View: (x) () REFRESH works!
Report Viewing: () (x) () () Pagination View: () (x) REFRESH fails to display Report Viewing: () (x) () () Pagination View: (x) ()
Report Viewing: () (x) () () Pagination View: (x) () REFRESH works!
OR: () are the radio buttons
Report Viewing: () () (x) () Pagination View: () (x) REFRESH works
Report Viewing: () () (x) () Pagination View: (x) () REFRESH fails to display Report Viewing: () (x) () () Pagination View: () (x)
Report Viewing: () () (x) () Pagination View: () (x) REFRESH works

I am using the session variable to hold the Pagination Viewing option but during page states, I've noticed that when a 2nd option is selected of *2* radio buttons (doesn't matter of 1st or 2nd option was initially selected) that during debugging mode the step over corrects the issue but not the right table viewing. Upon entering Page_Init selection selection index of radio button list returns to 1st option.

Asp.net - Grid View - View State For Nested Controls?

Jul 14, 2010

I have a grid view with a nested text box in it.I would like to turn view state off but the fact of the matter is when data is posted,the text boxes inside the gridview aren't available (there are no rows in the gridview on postback). Control's information is not stored in the View State (for things like selected value and .text etc.):Control state,introduced in ASP.NET version 2.0, is similar to view state but functionally independent of view state.However,control state cannot be disabled. Control state is designed for storing a control's essential data (such as a pager control's page number) that must be available on postback to enable the control to function even when view state has been disabled.

I have a data pager, and I have hyplerlinks for items in the list view that take you to a file upload or file delete page, and then returns to the list view. It returns to the list view's initial state (first page).

Is It Possible To Place View State In The Session

Feb 15, 2011

(I have a feeling i'm making a mental error thinking this is possible, because it seems too easy, but here goes)

For my intranet web app with 20 users on slow machines, the view state is slowing down their browsers.

But the network is local and fast. So I think to myself, why bother putting all that data on the user's browser?...Something like putting it in the database and then all the page needs to maintain is a unique key. But then I remembered that's how session state pretty much works.

QUESTION: Am I missing something or is this really possible?

Are Events Based On View State In C#

Nov 8, 2010

I've read somewhere that events of ASP .NET are based on View State of ASPX page. The values of submitted controls are matched with their value of view state and if any difference is found then the corresponding event is called up.

"When events are really based on view state than why events are fired even when the view state is disabled using EnableViewState=false."
