<asp:TextBox ID="TextBox1" runat="server" EnableViewState="false" />
<asp:Button ID="Button1" runat="server" Text="Button" />
I have set the EnableViewState property to false, but when I click on the button the value in the textbox persists after the postback. Why does the value persist?
I have a web page which is using PasswordRecovery control.
But I have a scenario in which I have to disable Viewstate for the whole application.
Now after disabling viewstate when I visit the webpage I have noticed that PasswordRecovery controls is not working (Every times when I submit the default button to go to step 2, the postback occur but not moving to step 2).
Can i disable viewstate on asp.net 3.5 applicatoin because i don't know programming on asp.net mvc?
View 3 RepliesNow here is the weird thing. First i am running it locally on the built in vs2008 web server.I load my control in fine, do a postback from a linkbutton, locally on my machine it all works fine, no issue.However when it goes onto my host, it falls over with the message:
Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request.Now i also load controls dynamically and use postbacks and things in the admin area of the site...and that works fine, however my front end just keeps failing? See the code behing below:
[Code]....
I have a site that features some pages which do not require any post-back functionality. They simply display static HTML and don't even have any associated code. However, since the Master Page has a <form runat="server"> tag which wraps all ContentPlaceHolders, the resulting HTML always contains the ViewState field, i.e:
<input
type="hidden"
id="__VIEWSTATE"
value="/wEPDwUKMjEwNDQyMTMxM2Rk0XhpfvawD3g+fsmZqmeRoPnb9kI="
/>
EDIT: I tried both variants of setting EnableViewState on page level with no luck at all:
<%@ Page Language="C#" EnableViewState="false" %>
<%@ Page Language="C#" EnableViewState="true" %>
I realize, that when decrypted, this value of the input field corresponds to the <form> tag which I cannot remove because it is on my master page. However, I would still like to remove the ViewState field for pages that only display static HTML. Is it possible?

View 3 Repliesis it possible to disable sorting on specific columns? 5 out of 7 columns have to be sortable, two not sortable. The columns are created dynamically in code behind, so I think doing this with mark up is out of the question. When I say disabled, I'm hoping that the underline wont show on the column header when you mouse over it.

View 2 RepliesI have a form where one of the fields would allow entry of HTML tags.
<asp:TextBox ID="someID" runat="server" TextMode="MultiLine" />
In this field I have a RequiredFieldValidator validation only. Unfortunately, after any PostBack if the content of any of the fields includes HTML tags or any other potentially dangerous code - the entire ViewState is cleaned.Setting ValidateRequest to false does not help. I'm using IIS 7.5 and .NET 4.0.
This question is regarding one of your article on disabling future dates in [URL] ....
Your code in the above link disables(prevents for selection) dates for selection greater than today.
But I want to prevent users from selecting dates after a particular date say for example-after 13th October 2013, all the dates should be disabled.
I replaced this line
var c = (new Date).setHours(0, 0, 0, 0);
with
var c = (new Date("October 13, 2013 11:00:00")).setHours(0,0,0,0);
in the javascript file(Extension.min.js).
But still it was disabling dates other than today.
I am using two text boxes for email id and password,and a submit button inoreder to login.In the same page itself I have provided a link button for forgot password.For the two text boxes I have provided required field validators.So when I click on the Link "Forgot Password" I cannot move to other page since the requiredfield validators prevent thatr.
View 1 RepliesI have dropdownlists inside a repeater. I would like to do something like this but can't figure out the syntax:

I'm not sure if the JQuery implementation will be as simple as this, or the approach will be a little different?

View 1 RepliesI want to be able to find the old value of a asp.net control (textbox, checkbox etc) without relying on events (e.g. OnTextChange event). Something like "someTextboxControl.OldText" would be perfect! I imagine that it is stored in the viewstate and need to somehow get at it via a custom control.

when the page is not Posted back, I saved all values in the viewstate.
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 am having issues with my dynamically loaded control's events.Here is how I am loading the control:
protected void Page_Load(object sender, EventArgs e)
{
LoadSubPageEditTemplate();
}
protected void LoadSubPageEditTemplate()
{
pnlPageTemplate.Controls.Clear();
BaseOfferAdmin adminControl = (BaseOfferAdmin)this.LoadControl("~/Controls/SingleOfferAdmin.ascx");
if (adminControl != null)
{
adminControl.ID = "Control_ID"
pnlPageTemplate.Controls.Add(adminControl);
}
}
}
The LoadSubPageEditTemplate() is also fired from a button event on the page, since I have to update it after the button event has executed.
The control loads perfectly, I have tested it with a basic button and the postback fires as expected. However, I am getting weird results with CheckBoxes.
<asp:CheckBox runat="server" ID="cbOptionalAction" Text="CheckBox" AutoPostBack="true" OnCheckedChanged="cbOptionalAction_CheckChanged" />
The CheckedChanged event only fires when the Checkbox is checked, which I guess means there is some issue with my control viewstate. If I have multiple checkboxes on the page, and one creates a postback, the checkchanged event is fired for each checkbox that is checked.
I thought disabling ViewState for a server control would cause this control not to keep its state after a postback. I thought the same would happen if I disable ViewState for the whole page.
However, I tried to create an example to show this to a colleague and was puzzled when a textbox on a page would keep is state (in this case its Text property) after one or more postbacks, even when ViewState is disabled everywhere (both at Page level and Server Control level). Please see the code below:
[Code]....
I can keep pressing the Post back! button and every value typed on the textbox is still there after the postback(s). I'm using VS 2008.
After this example I now assume I don't understand ViewState as I thought I was.
