Forms Data Controls :: Treeview Not Displaying Images?
Mar 14, 2011I've got a treeview inside an updatepanel. Currently I'm developing on a dev server through a remote connection, when I view the page from the dev server itself, it works. The expand/collapse images display fine. When I view the page from my machine's browser (same url, same browser) it doesn't display the images.
I've added custom images using the CollapseImageUrl/ExpandImageUrl properties, again it works from the server, but not from my machine. The actual rendered html differs. The page also contains some asp:Image controls which work fine in both browsers.

Mar 1, 2011Periodically a rash of occurrences of the following error happen. I believe they're the result of hack attempts. Whether that's the case or not, my question is how can I handle the error? I want to avoid unhandled exceptions. The TreeView control is just
a standard .Net TreeView control, not a custom one. If you suggest a code solution, please code it in VB.Net as that's what I'm using.

View 7 RepliesWeb Forms :: Want To Create Combo Box With Multiple Columns?
Apr 14, 2010 SQL query below: [Code]....
Basically i want to create combo box with multiple columns, I am aware that there is couple different solutions on the web, but I have decided to go for SQL query as I think it does not takes as much resources as Ajax Extender method, or label+GridView method,
Result of the query is:
DELL................Power Vault Ultrium LTO 4
1
Plextor.............PX-810SA
2
Asus................CRW-5232A3
3
Dell................PowerVault 110T LTO2
4
tes.................tes
8
This is test........This is test
As you can see it columns are not in line, I spent hours trying to find the way to "assign static length for SQL Columns".I want to assign 20 chars block for BackupDriveMake, and the same for BackupDriveModel and then combine them under one name using AS option. So if for example if backupmake takes 4 chars it will fill rest with blank spaces.
Example:
DELL
Power Vault Ultrium LTO 4
Plextor
PX-810SA
Asus
CRW-5232A3
Does anyone knows the way to do it in SQL, or maybe there is a way to format bound items in DropdownList in aspx webform.

Web Forms :: Event Handling Of Dynamically Created Combo Boxes?
Jan 18, 2010I am creating n number of Combo boxes dynamically at run time and adding a Handler of Combo1_SelectedIndexChanged() to the combo boxes.
At run time, When I select an item from one of the Combo boxes, the event fires n times rather than 1.
So for example : If there are 5 combos created, and I select an item from my first combo, the event Combo1_SelectedIndexChanged() , fires 5 times and that is an issue for me. How can I restrict this to run only for the combo that I selected.

View 6 RepliesWeb Forms :: Favicon Displaying / Not Displaying?
Mar 8, 2011I have issues when developing under Visual Studio 2010 and getting the favicon.ico to display. I have used favicons in production sites (sites running on Windows Server 2008, for example) and have no issues. But when I try to get it to display when testing new code under Visual Studio 2010, then I have difficulties getting it to display. Then sometimes it will display just fine with no assistance (see next paragraph). Before anyone says it...Yes, I have a file in the root directory called "favicon.ico". No, it will not display (in certain projects) when the site is run under VS2010...UNLESS I TREAT THE URL IN THE BROWSER THE SAME AS WHEN RUNNING UNDER FIDDLER2. That is to say, it will only work if I add a period character (.) in the url after the "localhost" entry [URL]. This url will cause the favicon to display every time. If I leave out the period (.), then the favion will not display -- and Fiddler2 will also not display the activity when the page is displayed/refreshed. As I said, this is a sporadic issue. I have some projects where the favicon displays fine. Then I have others where it does not...unless I put the period in the url after the locahost word. Can someone explain to me why:
(a) The period is required in the url to get Fiddler2 to "catch" the activity;
(b) Why does this same phenomenon affect the favicon as well; and,
(C) Why do some projects display the favicon fine when run under VS2010 WITHOUT the period being added?
I just do not understand what the period character in the url string is actually causing to happen and why it doesn't happen when it's missing.

Combo Box Choices Messed Up
Jun 14, 2010I have a combo box that looks great in the designer, the list of choices are perfect. But when I view the ASP code, or the published webpage the choices are seriously garbled. I have tried adding items, but it does not seem to regenerate the code. Any ideas why it happened and what I should do? I do most of my editing through the designer GUI. Note the blank items and even items mixed up together: TVCricket
