View 3 RepliesState Management :: Losing View State Upon Refresh?
May 13, 2010I 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.

View 9 RepliesAsp.net - Grid View - View State For Nested Controls?
Jul 14, 2010I 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.

View 1 RepliesWeb Forms :: View State Truncated And A Blank Web Page?
May 19, 2010Recently I had migrated my ASP.net 1.1 based application from a IIS5.1 based platform to a IIS 6.0 based Platform.The new platform has 4 nodes with a load balancer.
One of the page of my application, which is perhaps the heaviest one in terms of form components like textboxes, dropdown is not behaving properly.Some times the users only get a "Blank White Screen" and some time they get a "Invalid ViewState" , Invalid length for a Base-64 char array.
Based on the KB
http://support.microsoft.com/kb/831150 I understand that the view state is getting truncated.
I had been facing this issue since we migrated to the new platform and the application was working perfectly fine on the old platform.

Forms Data Controls :: View State And GridView With Template Column
Mar 2, 2011I have a GridView that isn't databound until the user clicks a button...
[Code]....
The GridView has one bound column: the employee name. It also has a template field that has an empty asp:Table.
[Code]....
I populate the tblInfo in the RowDataBound event.
[Code]....
The CreateInfoTable(...) method manually creates the rows and columns for the employee. This works, and I can see my dynamically created table; however, after the user submits the form back to the server for PostBack, the rendered page after submission is missing my manually populated table. How can I save my table across PostBacks?

View 2 RepliesIs 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?

Nov 8, 2010I'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."

C# - View State Not Retaining Values?
Jan 7, 2011I'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.
