Hitting The Back Button Makes The Page Crash?

May 4, 2010

I have two pages, step0 and step1.

Users get firsly to the step0 page, where they fill some info, the page updates, they fill some more, and then get redirected to step1 page.

Problem is that upon getting to the Step1 page, if the user clicks on the back button, then he gets to the last stage of the step0 page, which uses sessions and variables that are no longer existing, what causes a crash.

I'm looking for an elegant way to make sure that with each page visit, the page will restart itself to start phase.

I have this idea maybe twitching the Page_Load function, something about the is_post method, but since each page's post back hits this function,

Web Forms :: Make Sure Hitting Enter On The Page In Any Other Text Box Doesn't Post Back To SearchPage.aspx?

Feb 28, 2010

I have a master page which includes a search textbox and a button which posts back to another page. The controls are defined as follows:

<asp:TextBox
ID="SearchTextBox"
runat="server"
style="margin-left:
0px"
Width="170px" />
<cc1:TextBoxWatermarkExtender
ID="SearchTextBox_TextBoxWatermarkExtender"
runat="server"
Enabled="True"
TargetControlID="SearchTextBox"
WatermarkCssClass="watermark"
WatermarkText="Search Name" />
<asp:Button
ID="SearchButton"
runat="server"
Text="Search"
PostBackUrl="~/SearchPage.aspx"/>

The problem is that for any other TextBox on the page which is using this MasterPage, for example the login page, if you type your user name and password and hit Enter, The page is redirected to the SearchPage. If you click on login buttton everything works fine. How do I make sure hitting enter on the page in any other text box does not post back to SearchPage.aspx?

Page_Load Event Is Not Revoked When Back Button Of Browser Is Clicked?

Apr 8, 2010

I have a very common problem with asp.net . I have designed a webpage that performs some action on its load event but whenever a user clicks on back button those actions are not performed as Page_Load event is not called.I have searched a lot of forums but wasn't able to get a exact answer. All I was able to know that it was happening due to cache memory maintained by browsers. I don't want to delete that cache. I want browser to work in normal way.

ModalPopupExtender - Hitting Enter Key Activates A Button On The Page, Not The Popup?

Mar 23, 2010

I am having an odd issue where when I hit the 'enter' key, a button on my page (not on the Popup) is being activated. Consequently, it is firing a command that I do not want fired.Put another way, I have a ModalPopup with a 'TextBox', 'Image', and three buttons. I can click inside of the TextBox, begin typing, then hit 'enter', and for some reason it acts as though I am clicking on a button that is on my page, not on the Popup.

AJAX :: Modal Popup - Hitting Return Fires Button On Main Page?

Feb 20, 2011

I have a modal popup and the CSS prevents anything from being entered on the main page.

However, when I hit enter while the modal popup is displayed, a button on the main page is fired.

It seems to only happen if the button on the main part of the page is pushed down out of view so it is not currently on the screen.

How can I prevent a button on the main page from firing when the user hits enter?

Web Forms :: How To Tell Try Catch To Not Log Into Event Log

Sep 27, 2010

I have a property call (add user to a group) that would be hard to write code to check if user is already in group and I need to call it multiple times sometimes for the same group. anyhow it throws an error if user is already in group. easy way if to just put in a try catch and do nothing for the catch. it works fine except there are several errors in the application event log for this error when it happens. I would rather it not to log this error as it takes up time when looking in the event log to say - this is not a valid error log. so is there a way to tell a try catch to not log in the event log an error it is catching? I would rather not change any settings for the whole site but perhaps just this 1 page might be acceptable.

Forms Data Controls :: Back Button Doesn't Go Back When Canceling / Updating Edits In Gridview?

Mar 31, 2010

I have a gridview bound to a sqldatasource with editing enabled. If I click Edit, then either Cancel or Update, the update or cancel occurs and the Edit button reappears. However, I cannot then click the browser's back button without having the Update and Cancel buttons reappear. A second click of the back button takes me to a state where the Edit button shows again, *then* another back button click will take me to the referring page (the one before the one with the gridview on it.) IOW, it looks like the postbacks are cached. How can I prevent this and have the back button go straight to the referring page?
