My question is why do we need to Bind() Gridview on evrytime we click on Paging.
If Gridview has a view state then the paging should work from View State then why do we do something like the following on Page Change Indexing. Why do we have to call the database ?...
Gidview1.Datasource = DatabaseCall();
Gridview1.DataBind();
I have created a customized GridView Control.
I have created a property called as IsEntryGrid. Which is boolean. If it is true then it is assumed that it will be a grid where dataentry is possible from footer controls. Controls in footer are created dynamically. My problem is that when i m pressing ok image button control state is not maintained.
eg. In my footer say there is a text box for field OrganicationCode. I enter Org Code as M01 and if i press enter, i m not getting that back in my page event..
my code to create grid footer....
[Code]....
protected override void CreateChildControls()
I 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?
I have a gridview in which I have the autopaging option set to true, when i load the grid everything works on the first page, i can even go to second page , but when i click the edit button nothing happens and after that any click blows up the page giving me error Faile to load view state.
View 5 RepliesI 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 am having a ASP.net application it having three pages ,page 1,page 2,page 3,when the user navigating between this pages I want to maintain the view state in page level after postbacks(i.e.) .If a user visits page 3, passing some query loads some data .then he moves to page 1 doing some entries .after that he once again moves to page 3 now I want to display the data previously available at the time he moves to page 1, same
way I want to do to my three pages up to the user logging out.

View 3 RepliesI 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 RepliesI have a simple user control containing two text boxes which I am adding to placeholder on Button Click event. I am storing the number(count) of clicks in View state and running a loop using count to create all previously added user control. I am also adding IDs to each User control (appending "UC" and count). I have also checked in view source the ids are same each time they are created. I have another button which basically does an post back. I have EnableViewState enabled ="true" in all controlls all the way up to Page Level. My problem is that User Input does not persist on postback. Should this not be happening automatically for me?

View 7 RepliesI'm having troubles remembering how to grab the list view's state, or page, so that when you leave the list, you can return to the list view page you left on. 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).

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?
Which one more costilier View State or Session when a bulk data is stored. Why?
View 2 RepliesI'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."
