Asp.net - Dropdownlist Is Cleared On Page Postback
Apr 8, 2011I have a FormView bound to a SqlDataSource on my page. One of the controls on the FormView is a DropDownList, which gets populated on Page_Load (it's being populated with a list of file names from a specific folder).
Everything goes well when the page first loads. I am able to view the list of files, select one and, upon hitting the "save" button, store the correct filename in the database. However, when the page refreshes after the post back - the DropDownList is empty.

Asp.net - Browser History Cleared After Navigating To A Pdf Via Href?
Feb 23, 2009I'll start off by saying my website has a landing page of http:[url]....
On PageOne.aspx, I have a link to another page: http:[url].....
On PageTwo.aspx, I have an link to the following:
<a href="http:[url].....
The /MyFiles/ directory is actually a virtual directory which points to a file server that holds many other files (PDF, jpeg, doc, etc.).When I navigate to PageTwo.aspx from PageOne.aspx, I can click "back" and still get to PageOne.aspx (my browser history is ok). When I click on the link on PageTwo.aspx, the PDF opens in the same window...then I can click "back" to get back to PageTwo.aspx, but I can't click "back" again to get to PageOne.aspx (it seems like my browser history has been reduced by one page).
I can only imagine that this happens because of the virtual directory since I can't duplicate this problem if the PDF resides on the same server as my .aspx pages. If that is the case, does anyone know how to get around this and still have my PDF reside on the file server (virtual directory)?

Get All My Textboxes In Tabcontrol Tabpage1 To Be Cleared Of Text Thru The For Each Loop
May 11, 2011Trying to write my program in vb.net 2010. I have read my 2 books and have been playing with the code a bit. Got streamreader and writer and My Namespace understood as far as text files go. Now I'm trying to get all my textboxes in tabcontrol tabpage1 to be cleared of text thru the For Each loop.
I've tried various ways and keep getting invalidcastexception error. I even changed the tabcontrol and tabpage modifiers to public. That did not work either.
[CODE]:....................
I thought the code would not only clear all textboxes on tabpage1 but on all the tabpages. The help tells me that "When casting from a number, the value must be a number less than infinity and to make sure the source type is convertible to the destination type. I have three tabpages and that is definitly less than infinity. The source type and destination type puzzle me a bit.
Here is what I got using intellisense, however it not only clears the textboxes of text on tabpage1, but it clears the labels and buttons of text too so it is not a perfect solution.

View 1 RepliesList Getting Cleared Every Button Click Inside Update Panel?
Apr 22, 2010url...I've got a drop down inside an update panel, and I am trying to get it to allow the person using the page to add users to a list that is bound to a gridview. The list is a global variable, and on page_load I set that to the gridview's datasource and databind it. However, anytime I click the 'add a user' button, or the button to remove the user from the list. It appears like it is doing a full post back even though all these elements are inside the update Panel.[code]Now I thought the point of an update panel was to be able to update things inside of it without doing a full post_back and reloading the page. So if that's the case, why is it calling page_load everytime I click the buttons? I ran this code and debug and I see that even before any of the code associated with button press fires, page_load runs again.I tried putting the gvAssociatedUser.Datasource = associatedFaculty and the line below inside the Page.IsPostBack check, that prevented the page from working. I tried every combination of settings of the update panel for ChildrenAsTriggers and UpdateMode, and none of them worked.
I've tried won't get it to work.It wasn't causing a full postback so I was wrong as to the cause. I thought the page was doing a full post back thus resetting my associatedFaculty list global variable, but it isn't doing a full postback.The issue I am having is everytime I click btnAddUser it will add one element to the associatedFaculty list and thus bound to gvAssociatedusers. This works the first time, but the second time I click it, it overwrites the first element. So it appears like my associated Faculty list is getting reset each time I click the button?

"Cleared" Event Gets Added To The Listview?
Nov 11, 2011I've made a SCADA system with VB.net and AdvancedHMI, which is a program that monitors plant equipment etc.I've also made an alarm logger which out of a listview, so, when an alarm comes in, say "Alarm 1", en entry gets added to the list view as an "Active" event.
If the alarm clears, then another "Cleared" event gets added to the listview.This works OK, but when you start to get lots of alarms, it's difficult to determine which alarms are actually active, because you may have multiples of the same alarm.What I want to do, is to be able to press a button, which looks for when there has been an "Alarm" event and then a "Cleared" event for the same alarm, and then removes both of them from the listview. So it should then show only active alarms.I know that maybe a listview possibly isn't the best choice for my ultimate goal,
