View 3 RepliesChange A Value On Multiple Items?
Feb 3, 2009I have not programmed since the late 90's (VB 6.0)Using Visual Basic 2008 Express, I'm creating a simple program but have one question:Is there a quick way to change a value on multiple items? For my program, I need to make a group of text boxes (anywhere from 14 to 546 unique boxes) "Enabled = True" or "Enabled = False" depending on a user selected value.
In a little more detail: The user selects the number of data rows on one tab. On the other tab are 40 rows of text boxes (14 boxes per row). If the user selected 15 rows, every row below 15 should be "Enabled = False".Thus far, I've coded a bunch of if-thens that run each time the user changes the selected rows (a line for each text box that makes it enabled or not). There are then 40 if-thens with lots of code in each.
I am sure there is an easier way to accomplish my goal without using hundreds of lined-up text boxes.

Disable Multiple Items From DropDownList?
Jun 6, 2011I would like to disable a specific items from DropDownList. I have below code but it does not working. DropDownList have 5 items.And,I'm getting error:Index was out of range. Must be non-negative and less than the size of the collection.Parameter name: index
Protected Sub CheckBox1_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged
Dim X As Integer = 0 <> 1
DropDownList1.Items(X).Enabled = False
End Sub
But, if I add a different value for X, then it disable 1st and 2nd item.

Dim X As Integer = 0 or 1
DropDownList1.Items(X).Enabled = False
End Sub
My goal is if I would have a 365 items in DropwDownList to disable items for example between 120 and 150.
Gridview Templatefield With Multiple Items?
Jun 19, 2012I am creating a web application in ASP.net/VB.NET and I have an issue with the gridview.Currently, I have the gridview populated with data from the DB and I've also coded the update button to allow the user edit any necessary information through a form that pops up.[URL]...
What I'd like to do, if possible, is add a button to the two right columns(I already put one in the Dock Out Time column) which will be invisible if the column is set or will set the current time to the column. Setting the time for those two columns is already handled through the update form, but my supervisor asked me to try and see if this was possible.
Those two Time columns are Templatefields(since I format the display time from what is actually in the DB) and I added an asp button in the ItemTemplate for that Set Button in the picture.Is this even possible to do and if so, how would I access this button in the code behind so I can add functionality(setting the time and hiding it if the column is not null)If it's not really possible to have two items like this in a templatefield I can just make 2 extra columns for these buttons but I think this would look much cleaner.

Multiple Data Items In Single Field?
Apr 30, 2009What I'm trying to do - VB 2005 express and sql 2005 express editions - Trying to set up just a basic hardware/software inventory program. As is I've got separate tables for computer and software licenses...with ComputerID and LicenseID primary keys respectively...where I'm bumping into walls is that I wanted to be able to link them together with a foreign key, for example the computer record would have a foreign key for LicenseID and when a license would get installed the ID would go in and there'd be a nice pretty link. However I run into scenarios where a computer might not have any software installed...or might have more than 1 software item. Or a single software item may be installed on 1 computer, multiple computers, or nowhere. It possible to have that single foreign key field link to multiple records from the opposite table?
What was originally suggested to me was to have a 3rd table called Installations. It'd have 3 rows...one named InstallationID as the primary key, and 2 foreign key rows named ComputerID and LicenseID that linked to the other tables, so that when a license was installed, a record would be added to the Installations table, and later on when we wanted to see where all a particular license was installed or what licenses a single computer had, the table could be filtered by computer ID or license ID and all matching records could be displayed. When I tried that out though I'm having a heck of a time getting the correct items to display.
Just as a basic test i set up a new form and dragged the tables onto it from the Data Sources window using "Details" view for each of them, so that it set up the table adapters and binding sources and navigator for me. I got rid of the auto-added labels + textboxes on the form and added just a couple new textboxes, 1 linked to the licenseID and one to another row i had in that table for productkey...tested it and it moves through the records fine and the correct data shows up in each box to correspond with the other. now though I'd like to add another control to display each of the ComputerIDs that are linked to the particular license being displayed in the other controls via the foreign keys routing through the Installations table, but I'm not having much luck.

Multiple Textboxes Bound To Different Items In List?

I also want to be able to track CurrentItemChanged Event for updating purposes. My initial thought was to use a list object as the binding source but how would I cycle through the list if it returns more than one so that I can assign the values to the 2nd and 3rd textboxes or if data is entered in to a blank textbox I want the currentitemchanged
