Is there a way to access viewstate of a page in another page ?Please elaborate the answer to clear my doubts as I think ViewState has it's scope to the page only and can't be accessed outside page.
View 1 RepliesI stored a object in viewstate on Page. Now when i access the same viewsate object on usercontrol,it shows as null. I even tried creating the same viewstate with same name in usercontrol and page.Both holds different value. I understand that viewstate is a protected property. How does this thing implement in above scenerio or is there any other reason for this behaviour.
Edit:
Usercontrol is there in the page markup. I am not loading it dynamically. I have a page EditFacilityworkType.aspx. On page I have a usercontrol FacilityWorkTypeDetails.aspx(FacilityWorkTypeDetails1). Inside this usercontrol i have a user control Workflow.aspx(Workflow1)
Page_Load() of Page I am retrieving workflowdetails on page_load() of page.
FacilityWorktype facilityWorkType = facilityDetails.GetFacilityWorktypeDetail(SessionHelper.FacilityWorkTypeID);
ViewState["WorkFlow"] = facilityWorkType.FacilityWorkTypeWorkFlow
Inside usercontrol FacilityWorkTypeDetails.aspx. I have a property
public FacilityWorktype FacilityWorkTypeDetails
{
get
{
#region Fill FacilityWorktype
return GetEntityFromControl();
#endregion
}
set
{
PopulateControls(value);
}
}
Now i set this property in page load of page
FacilityWorkTypeDetails1.FacilityWorkTypeDetails = facilityWorkType;
Inside Workflow.aspx, I have a property
/// <summary>
/// Property to fill entity object from controls on this page
/// </summary>
public WorkFlow WorkFlowDetails
{
get
{
return GetEntityFromControls();
}
set
{
BindTranscriptionMethodDDL(ddlTranscMethod);
PopulateControls(value);
}
}
Now PopulateControls() of FacilityWorkTypeDetails1, i am setting property of workflow1
private void PopulateControls(FacilityWorktype value)
{
Workflow1.WorkFlowDetails = value.FacilityWorkTypeWorkFlow;
}
Now when i am retrieving values from
private WorkFlow GetEntityFromControls()
{
WorkFlow workFlow = (ViewState["WorkFlow"] as WorkFlow) ?? new WorkFlow();
//workFlow is null
}
So now inside this function workFlow is null. I want to ask,why is it null when i have set viewstate in page.
can we access viewstate and session objects at unload event of page.
View 2 RepliesI 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.
What ASP.NET page lifecycle event can I write code in to determine the size of the viewstate that being sent out? Also, is it possible to determine the size without parsing through the rendered HTML (like a property on the page object) or is parsing the only way?
What I'd like to do is log the sizes, specifically if they cross a certain threshold.
I have a clarification on Viewstate. I have used the Viewstate machanisum to save the data in particular page. I have to get my viewstate data from one page to another page. How can i get the values? First let me know Is it possible? I have gone over many articles. i did not clear with it.I have an aother option for it. Thats Session. I need not use this techinque. Please provide more information about the viewstate..

All I want to do is access the <body> element from the code-behind of a content page and add a class name to it.
I have a top-level master page with the <body> element in it. Then I have a nested master page which is the master page for the content page. From the code behind of the content page I want to add a class name to the body element. That's all.
I have this in the top-level master:
<body id="bodyNode" runat="server">
I added this to the code-behind for the content page:
Master.bodyNode.Attributes.add("class", "home-page");
And I get a message that:
System.Web.UI.MasterPage' does not contain a definition for 'bodyNode
If I add this to the aspx content page:
<% @ MasterType VirtualPath="~/MasterPage.master"%>
The message then changes to:
bodyNode is inaccessible due to its protection level
I've wasted like 2 hours on what feels like something that should be really simple to do

View 1 RepliesWhat are the latest and greatest ways to move ViewState to bottom of the page Can this be done in a IHttpHandler that can be specified in the web.config to intercept requests to "*.aspx"?
<httpHandlers>
<add verb="*" path="*.aspx" type="MyApp.OptimizedPageHandler" />
<httpHandlers>
Other options is that this could be done in a IHttpModule, but that is not as performant, as it will intercept all requests. Also it could be done in an a class deriving from the Page or MasterPage-class, but this is not as modular.Are there any performance penalties to this?

View 2 RepliesIf I disable ViewState at Page level, will it be remembered for GridView inside the page?
View 1 RepliesWhen you create an ASP.NET page with no controls and runs it, a view state hidden field is added.
Looking at what's in it (with ViewStateDecorder) reveals that there's a single value there that contains a number.
My question is - what is this number?
P.S. I guess this value appears on every page, with or without controls.
I've got a master page with a section for subnavigation links on it:
<div id="sub_nav" runat="server"></div>
I programatically populate this with Hyperlinks when my main asp:Menu data is bound depending on the address of the page I'm on.
This works fine and all my correct submenu stuff shows up on each page. The problem is that when one of these pages does a postback, I lose all the links that were in my sub_nav div.
Now, I could just populate the div with links every time regardless of whether the master page load is a postback or not, but I figured there is a better way of doing this. I was thinking enabling the viewstate on the div and links inside it might persist them through postbacks, but apparently that is not how viewstate works.
i want to give id of dropdowncontrol inside master page, how can i assign this control id in trigger of updatepanel inside content page
