C# - CheckboxList Not Setting Selected With Viewstate Disabled?

Apr 27, 2010

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?

Web Forms :: Checkboxlist Disabled Items Selected Status?

Jul 6, 2010

I have some checkboxlists on a webform. Based on some options chosen by the user i make some default selections from the checkbox list and disable the entire list on the client side. When i submit the page i'm not getting the selected items from the checkbox list, when i debug i found that listitem.Selected always returns false even though the listitem is selected, i understand this is because the entire checkbox list(all check boxes) is disabled. how to get this with out writing any extra code which is my last option.

C# - Page With ViewState Disabled Still Be Validating A Viewstate Field?

Sep 24, 2010

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.

ViewStateMode Disabled But Still Getting ViewState Element?

May 14, 2010

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.

AJAX :: NoBot Fails When ViewState Is Disabled?

Feb 24, 2010

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.

C# - Can't Access Control In Form When Viewstate Disabled

Mar 19, 2011

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

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.

Forms Data Controls :: ListView Paging With Disabled ViewState?

Jan 31, 2011

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

Forms Data Controls :: GridView Using And ObjectDataSource With Paging And Sort While ViewState Is Disabled?

Nov 12, 2010

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.
