Web Forms :: To Force A Page To Refresh Without Loosing VIEWSTATE Information?
Jul 19, 2010
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.

this is about ASP.NET, ViewState, UserControls and loosing the values of my properties. It is an classic question by know, I know, and even though I have searched here and on Google for a resolution to this problem, I havent succeeded. On the contrary, the more I test different things, the less I understand it seems.
On top of this I am using ext.net and their so called DirectMethod's but I dont think that has much to do with this problem. There are numerous questions I have and I hope that this text will be fairly readable and understandable =)
The UserControl
I have a UserControl, Customers.ascx, that contains some Properties. The "most" important is *_CustomerId*. The _CustomerId is set in code-behind, in ext.net's "DirectMethod" like this (code below from the Page Customers.aspx):

Consider I have 2 controls, C and CompositeC which contains C. Both C and CompositeC have ViewState.
Now consider a third control causes a postback.
The resulting life cycle will be as follow:
CompositeC tries to restore state. To do so it needs to create the child controls, so it creates C.
When C is created it's ViewState is restored.The third control's postback event is triggered. At this time a handler calls CompositeC.RecreatedChildControls() and C is created again.Everything renders.
The problem is that C state is not restored again after step 3. RecreateChildControls method should modify the control's state so that when C is reintroduced to the CompositeC control's collection it's viewstate is automatically restored but it doesn't.

I'll try to specify my problem as simple as possible! I have a problem comunicating between 2 pages; Products.aspx and ProductDetail.aspx. On Products.aspx i have about 15 DDL's on the left side (all set to autopostback), and 1 ListView ond the right side. Results in my ListView control are based on selcted items from DLL's on the left. Every single result in Products.aspx has a dynamical hyperlink to the ProductDetail.aspx. Now when I click on specific product in ListView I'm redirected to ProductDetail.aspx page, and everything works fine! If I click on the Back button in IE or FF it works also fine because it returns me to the previous Products.aspx page and all my results based on selected items in DDL's are still there!
The problem comes when causing some more autopostback's in ProductDetail.aspx page, because every autopostback is counted as a new page request and therefore i have to click Back button in IE or FF for more then 1 time to come back to the previous Products.aspx page.
I tried to implement code BELOW in ProductDetail.aspx.vb but it does not completly fulfill my expectations, becase all my searching criteria are lost when returned to the previous page (Products.aspx)
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack Then
ViewState("ReferrerUrl") = Request.UrlReferrer.ToString
End If
End Sub
Protected Sub BACK_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles BACK.Click
Response.Redirect(ViewState("ReferrerUrl").ToString)
End Sub
Does anybody knows any other solution how to come Back to previous page with only ONE CLICK without loosing searching criteria?

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?

I have a table on my page. I need to scroll down a little to get to that table. In that table i have som data that i edit and save to database. When the save is done i need to refresh the page( Response.Redirect(Request.RawUrl )) so it loads the new data to that table. When the refresh is done the page is on top again so that i need to scroll down again to see the table. This makes it very unusable for the user.
How can i refresh the page without it going back to top again? I tryed wrapping an updatepanel around the table but it didnt

I have an asp.net aplication and when I refresh a web page which is produced after a form is submitted, example
<form name="myform" action="mypage.aspx" method="post">
then the following alert is shown.
"The page cannot be refreshed without resending the information. Click Retry to Send the information again, or click Cancel to return to the page that you were trying to view."
with two buttons:
Retry Cancel
How can I avoid the above alert and take "Cancel" as default & refresh immediately?

I have a problem regarding to asp.net lifecylce hierarchy.
Basically, I have one user control which has a GridView in it. And this GridView is dynamically generated based on a public property on the control (named Parameter in the simplified code below).
Everything is fine when I insert this control in an aspx page, set its Parameter property and call DataBind(Parameter) on it. GridView is generated and populated on the UI.
Problem occurs when I post-back the page. I have to regenerate the GridView structure so that the data in the ViewState of the control can be used to populate the GridView. So that I can achieve its content. But as long as the GridView structure is generated dynamically and it is based on the Parameter property set on it, this is not possible. Because the OnInit of the user control is called before the OnInit of the page and that is why the Parameter property is set after the generation of the GridView structure. As a result I get an empty Gridview in the end.
Here is the code in a simplified way.
Can you give me some recommendation how to overcome this?
Can I explicitly force asp.NET to re-load the ViewState of a gridview?

I have been getting this error a lot lately with some of my users, and I had a couple of concerns with view state and I have read so many articles but I am still lost..
1. I use masterpage on all the pages and I need viewstate for some of the pages but..
There is a page where a user will fill out the information and then submit this data to a cgi server, and it is where I get most of the Client Disconnected errors, what would happen if I disable viewstate when they click on that button?
Now when a user browses from one page to another, does the view state from the previous page get deleted? If not how would I delete it?
Does the master page have its own viewstate? Would I be able to make sure none of items on my master page are using the viewstate?

I have a shopping cart page (Cart.aspx) that has a button that will (sometimes) post to a third party payment gateway, if payment is necessary. The payment gateway will process the payment and then do a silent post to my website (Order.aspx) so I can update the order status.
Order.aspx always throws an invalid viewstate error, even though viewstate is disabled on the page.
What's happening is that Cart.aspx (which has viewstate enabled) posts to the payment gateway, and the gateway will post it back as part of the silent post. Even though Order.aspx has viewstate disabled and validation disabled, it still tries to validate the __viewstate field it's being given.
I know setting EnableViewState=false will disable the rendering of the __viewstate field, but if another page provides the field, shouldn't it still skip validation? I tried calling ViewState.Clear() on the Page_Init event of Order.aspx, but ViewState is apparently empty. how to get around this? I don't want to disable ViewState on Cart.aspx (in some cases it may be necessary), but I can't figure out how to clear it on Order.aspx.

I need to write some code that will force a page to time out.
I tried putting a thread to sleep for a VERY long time, (It is still running as I type this) but it seems to just keep going...
How might I do this? (I need to test some code that should execute if a process times out {script not session} but I can't test it unless I can make it time out...)

This works in all scenarios `except` when I open the catalogue and select "close" instead of adding controls to the page. Selecting close sets the page back into "Display" mode. Is there a better way to do this?
