Asp.net - Drag & Drop In VB / ASP Using Controls Created During Runtime
May 18, 2009Site is located at [URL] and the section in question is the "configurator" button on my top row navigation. Everything is written in the latest flavor of VB.NET and ASP 3.5, and I have a SQL2005 server available with my host. Here is the down 'n dirty of my dilemma:
During pageload, I get a list of all the parts in my parts table. Then I create an image object and 2 label objects per entry and place them in my fancy accordion pane control. Works great so far, I can get a giant list of pictures and text that's aligned how I like it (for now). Now - I really need a way to be able to have a visitor drag an image/label/label combo from the accordion over to a panel (or anything really) on the right side that is currently invisible. Once the dragged thing is dropped into the drop target, I would like it to fire a function or sub that I write in VB.
From what I've seen about jquery, apparently there is a way to make an element on my webpage draggable, droppable, or what have you. The example code for it - I'm not entirely understanding so a quickie sample would be great. I'm a fast learner and can apply it from there to my project. More importantly, how do I get objects that are created during runtime to be draggable, and fire my event that I wrote in the only language that I know?

On Change Event For Dynamically Created Drop Dowlist
Apr 21, 2009I have a website where the user requires to add and remove Headlines from the main page.
The headlines are stored in a database with a column titled 'Display' (true or false) which decides if the headlines appear. I want the user to have the ability to add or remove headlines from the main page, so have created another page which creates a table of all headlines along with a drop down list containing 'Enable' and 'disable'. I want these drop down lists to work by when the user changes the value in the drop down list the database will be updated. Only I cant find how to give the drop down lists an on change event.

Drag And Drop From ListView Control, To Shell (Desktop)
May 20, 2009This is a little diffrent from your standard drag and drop, but I am trying to find out a way to support drag and drop, from a list control, which is displaying a list of files, held as "blobs" in a SQL database (compressed data in my own format). When the form is opened, I obtain a list of all the file names within that given table in the database, and display it to the user in the list view control. The user then has the option of dragging that ListItem from the ListView on to the dektop (or other directory location). Upon doing so, I need to be able to read the data from SQL, decompress the data (in my own format) and then save it as a file at the dropped location.
My main problem is detecting when the ListItem is dropped outside of my application, as I want to use this dropping event to trigger the code in to obtaining a copy of that file from the database, and save it in to the "dropped" directory, where ever that may be.
So Im mainly looking in to how I can "see" the final location where the item is dropped, and how I can start off the drag and drop operation in the first place with no initial data (since I have not obtained the file at the start of the operation). Getting the file at the start of the drag and drop operation intoduces "lag" while the application makes the trip to the SQL database (via web service) and obtains the data, so I need to carry out that trip to the database, at the end, while still allowing "Windows" to act as if I am dragging and dropping a file...
I did consider multi-theading, and downloaind the file from the database while the drag and drop operation is in progress, but then it becomes a race between the data being obtained from the database, and the user dropping the file.
Im using VS2005, SQL 2005 where the file is stored as a blog. SQL is on another PC running a web service which I interact with, to allow my application to talk to the database over both a LAN and WiFi via the internet. Compression and de-compression is handed at the client side application (for the file itself, in order to reduce the footprint created by the internet traffic) , where the user interface is displayed.

Access Objects On A Dynamically Created UserControl An A Dynamically Created Tab Page?
Dec 5, 2011I can usually find the answers to most of my questions via the Google Gods, but not this time.I have a form that has a TabPageControl and on that page a collection of labels and text boxes via a usercontrol.
On the form I have a button that allows the user to create a new tabpage, when the code adds a new page, it automatically adds the UserControl collection. I can't get my head around how to access the objects on the newly created tabpage.
What I need to be able todo is take the index of the tabpage that has focus and translate that against the UerContol name, but I havn't a clue how to do it!

Now the situation is, that in most cases it works fine. But a few of my customers report that the TextBox not appears on their dialog - it's not there!

BTW: The program is built with Visual Basic 2005. And the customers with trouble are spread about the OS's (XP, Vista, 7).
