Web Forms :: Textbox Contents Persist Even With Viewstate Disabled?
Jul 16, 2010
After witnessing some strange behvior I'm confused about ViewState again :/
My understanding was a textbox needed to have "EnableViewState" set to true otherwise when the you postback the fields contents would disappear.
That's not happening, I created a textbox and button and a label.
The button was set to copy contents of text box into the label when I pressed it.
I did and the text was populated into the label and remained in the textbox?
This was inside an UpdatePanel and the page itself has a MasterPage, so that might have something to do with it, but I have about 50 textboxes on this page all with viewstate=true on, so I would really like to know what controls need to have enableViewstate=true in order o function properly.

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.

On page1.aspx i hava a textbox with id="tb1"
On page2.aspx I have a textbox with id="tb2"
page2.aspx is set as postbackurl for page1.aspx. For both labels enabl;eViewState is true. Shouldn't the text I write in page1 also appear in the label on page2? Can I implement this without looking into Request headers, and setting the text myself?

If I disable the ViewState on a ListView, the events raised by it are no longer ired. OnPagePropertiesChanging is the ListView event I've always used in combination with the DataPager to update the ListView to the correct page once a DataPager item is clicked, but since its not being fired, I'm wondering if there are any other options. My ListView is currently in an UpdatePanel, and I'm caching the results that the ListView is being bound to. I could rebind the cached results on the PageLoad, but I can't think of a good way to determine if the PageLoad is being accessed because the DataPager was clicked, or for some other reason, so this doesn't seem like a good idea

I am using a GridView with an ObjectDataSource bound to a DataTable. I am using the GridView for displaying a report, NO editing is being done, just read only, however, I am sorting and paging. I need to turn off ViewState for the GridView to improve performance. After turning off the ViewState I start getting the error messages for both paging and sorting:The GridView 'gridView' fired event Sorting which wasn't handled.This is fine I just need to know how to implement the Sorting and Paging events correctly to leveage the ObjectDataSource. I would preffer not to remove the ObjectDataSource from use, especially if there is a way I can manually wire up the datasource correctly to continue to use the GridView as I had been when ViewState was on.Any help on getting the datasource wired up or a solution for handling the events in the context of the datasource would be great.

I have a ASP.NET 4.0 webforms site where I have the MasterPage so it is set to ViewStateMode="Disabled" along with the content placeholders being set similarly.
When I'd view my page I'd still see a ViewState field rendered, I then tried adding the ViewStateMode="Disabled" to the page level also but that didn't change anything.

I tried this in many scenarios and everytime the ViewState is disabled page-wide, NoBot raises an internal NullReferenceException and always returns InvalidBadSession. I suspect that you are referencing the ViewState and it returns a null value which is then used. It's probably a good idea to think about a way that avoids using ViewState.

I want to disable my viewstate in a form because its too bulky (about 1mb per page) due to retrieving some data from database and in other place on the same form I want to access a control from my master page. but when I set viewstate of Listview to false I'll get following error: Object reference not set to an instance of an object. what should I do in this situation? veiwstate is too damn bulky
and here is what I've written for accessing particular control:
Control cc = Page.Master.FindControl("mainContent").FindControl("ListView1").FindControl("itemPlaceholderContainer");
foreach (Control ListItemctrl in cc.Controls)
{
Control lblNewsId = ListItemctrl.FindControl("lblNewsID");
if (lblNewsId != null)
{
Type t = lblNewsId.GetType();
if (t.FullName == "System.Web.UI.WebControls.Label")
{
string newsID = ((Label)lblNewsId).Text;
foreach (Control childCtrl in ListItemctrl.Controls)
{
CheckBox ctrlCB = childCtrl.FindControl("chkItem") as CheckBox;
if (ctrlCB.Checked)
{
//based on DDLAction we will do the things ;)
}
if (childCtrl.FindControl("chkItem") != null)
break;
}//end foreach childCtrl
}
}//end outer if
}//end foreach listItenctrl

I have a CheckboxList that seems to load and do everything right, except for when I do a postback, it will not have the Item.Selected property set. I have viewstate disabled for the entire page.
I load it like so(inside Page_Load on every load):
foreach (DataRow service in d.Tables[0].Rows)
{ [code]...
and MyLabel never has any text added to it. I can verify with the debugger that it does reach the _Click's foreach loop, but no item is ever selected. What could be the cause of this?

I have created a really simple custom control to render panels into a page. The code is below. When I use my control and add any webcontrol to it, after each page postback the contents of these child controls vanishes.
I must have missed something really simple but run the example to reproduce this. Can anyone please enlighten me as to why the controls are being 'emptied' of their contents, and how I stop this occuring?
Here is the code for the control

And here's how I am using it in a sample page:

I have a couple of textboxes (actually a set of pairs of textboxes) where users can either enter a value or a percentage of a value but cannot use both. So in any given time some of these textboxes are disabled depending on which option the user chose.
For the textboxes representing percentages, there is a range validator to make sure only values from 0 to 100 are entered. If user selectes to enter datanot in percentage form, the percentage textbox gets filled automatically based on the value user enters. So if the total is something like 8 and user enters 2, the corresponding percentage textbox gets filled with 25% (minus the % sign).
However, the vaidation fails as if there is nothing there, persumably because the textbox is disabled. How do I get around this?

I am trying to make ONE thing work. The form currently have TWO Textboxes and ONE CustomValidator(connected to the first textbox). I simply want once I enter less than 4 characters in the first Textbox and tab out to the second Textbox and if Javascript is DISABLED then the server side code should stop me. I can achieve what I am trying to do if I use a button but I need to do it in the fashion I am trying decribing because if I have for example 20 textboxes on the form I want the user to see after each data entry that his validation was successful or not. Here is a sample of my code.

I'd like my users to upload MS Word documents -- instead of typing the information in a TextBox. Even though I use tinyMCE -- like in this site, most users still seem to prefer the highly sophisticated Word environment.
My goal is to allow them to upload their Word documents which I then convert to HTML and place it in a tinyMCE enabled TextBox control. Has anyone implemented this? If so,

Form1 is for the administrator. It has 5 fields. Field1 has a value for which the other values give details about it. This 5 fields are stored in a table. Form2 is for a user and its a data entry form. This forms has 12 fields. Each label in the form2 corresponds to the value of Field1 in form1. If suppose the admin fields 10 times the form1. The 10 labels of form2 are filled with values of field each time. The above is what I want to achieve. Also the two text box corresponding to the remaining two labels should be disabled for user.

I have a code where I fill some random text into a textBox. In this example there is more content than the textBox can show so the vertical scrollbar is shown in the textBox.
I wonder if there is a way to adjust the height of the textBox instead automatically so all contents can be seen instead of seeing the scrollbars ?
