I have a list box on a form and it works fine for what I want to do.I am wanting to edit items on the form, this means populating the listbox and then selecting the relevant items.
My listbox contains a list of item sizes, i want to select the sizes which belong to the item being edited.
can someone give me some pointers.I tried me.lstItemSizes.SetSelected(i,true) but this only works for a single item.

I want to select many items from the listbox in vb .net i. e i have the following code:
For i As Integer = 0 To Me.lstdep.Items.Count - 1

lstdep.SetSelected(i, True)
End If
Next
running the above code i can select only a single item from the sql server 2005.But i want to select multiple items which are seperated by comma in the back end ....
i have having a annoying problem to do with loops.

When the user selects a few rows from my list box i want to run code on them selected items which i can do fine, but when the user only selects one of items and hits the button. it goes throught the loop first and gets the picture and all is fine its when it comes back to this function after there are no more items to perform tasks on. it increments index again and then falls over because its out of bounds of the array. i want it to stop after one loop but i also want it to be able to have the multiselect option still so the user has a choice.
Im trying to figure out how to query a dataset when I select multiple values in a list box? I have the list box linked to the dataset and am using a button to search the values selected in the list box. I don't know what to do!

Can a listview multiselect in the same way as a listbox can, when it is set to electionMode = multiSimple?for instance when the listbox is set to selectionMode = multiSimpleyou can just select any number of items in the listbut...with a listview you can only multi-select when you hold down Ctrl. As soon as you lift the Ctrl key and click on an item it de-selects everything and only selects the last one you selected
View 4 Repliesi have been given the task of making a small program in vb.net to have two list boxes. The first list box contains the data and the second one is blank, when you select the one bit of data from the first list box it can be draged and droped into the other list box. my task is to make it so you can select multiple bits of data from the first list box and all that is selected is draged over to the second one when you drag and drop it.

View 1 RepliesI have a list box that is bound to a table in a database. It produces a list of companies. The user will then come along and select multiple companies that they want to view information about, and then they hit a select button which I'll display the company information (e.g company name, company site, address e.t.c) in a gridview underneath. However the issue that I am having is that it only displays ONE of the multiple companies selected and its always the top one. How I get all the companies to be displayed in the gridview?

I made a program (As usual) that plays media files using the ax.interlop.wmp.dll (windows media player). I also made a listview on the form that has gridlines. i have a problem with my mutiselect feature though. it just adds the same filename for every file, but in the amount files (Ex: if there is 8 files, it adds the name of the first one 8 times) i just want it to add every single filename to different rows, here is the current code that i have:
Sub openFile()
With OpenFileDialog1
.DefaultExt = "Mp3"
[Code].....
I've spent FAR too long trying to troubleshoot this simple operation.I want the user to select multiple files in an OpenFileDialog (called OpenFileDialog1), click OK, and then have the filenames display in a listbox (called ListBox1). When I run, the openFile dialog allows the user to select mutliple files. However, on clicking OK, the dialog repons allowing the user to select only a SINGLE file. Then, it throws an "outside of array" exception.

I have a listbox populated with dates in the format of dd/mm/yyyy e.g. 12/03/1983, 06/07/1987 etc.. Could someone please post the code that I could use so that I could search the listbox to multi-select the dates that fall within a specific month (not year or day). So for example I might want to highlight all the dates that contain the month **/10/** (october). I'm really struggling with this.
View 4 RepliesOk lets say you have a listview well call it "lv". There are items A, B, C and D. If i select A, C and D (holding ctrl) and hit a button it enters A, C, and D in a text box like below
"A(space)C(space)D(space)"
note: (space) is a space
how would i go about doing this? Below is the button that you would hit to send the selected items text into the textbox. (doesnt work)ERROR i keep getting: InvalidArgument=Value of '3' is not valid for 'index'. Parameter name: index

Ok, Im having trouble passing a value from one form back to another using a listbox... The user clicks a button in the main form to bring up an instance of another form (form2.show). In that form, the user then then selects a number 1-5 and then presses done:
Code:
Private Sub frmPlayer_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim x As Integer
If lboNumber.Items.Count = 0 Then 'list box is empty
For x = 1 To 5
[Code]...
How do I pass that value back to the main form as a value when the user clicks done?
I'm using VB.NET. I want to build a large List (Of MyClassOrStructure) that becomes static after its initial population.I'm going to have multiple threads that need to iterate through this list to read data (no writing, inserting, or deleting)

ok.. just as it sounds.. I'm kinda making a document portal app for work.. has 4 list boxes going to 4 different drive locations.. for cosmetic reasons I want only the last box you clicked in to show a selected item.. so if you selected box 1 item and it was hilighted and then you went to box 2 and selected something I wanted box 1 to then dissapear.
I have some code written to handle this.. but its not working so well.. since I use the SelectedIndexChanged trigger to fire off another piece of code to unselect all the other windows.. those listboxes fire their triggers also because I have to call lstWord. SelectedIndex = -1 to make it not have something selected anymore.. and when you do that.. it calls its SelectedIndexChanged and ends up deselecting everything.. so wasnt sure if anyone had done something like this before.. seems like something that would have been done before.. but as you can imagine searching the web for "multi list box select only one at a time" or something similar..gives you some strange results..
The first list box contains the project name. Based on whatever is selected in the Projects list box, the 2nd list box is generated with Custodian names associated with that project. I am having problems generating the 3rd list box. This holds the data sources associated with whatever is selected in the 2nd list box (Custodians)

View 3 RepliesI have been reading books and the forums for a rew days now trying to work out how to use any control to carry out the following:Basically, I want to display a selection e.g "Club Name" in a combobox (or similar control) and have the ID of that selection in a separate hidden column e.g. "ClubID". This will allow me to easily reference and store the actual "ClubID" in the required record when I save it back to the database.I can not use the "SelectedIndex" property of the control as the combobox is populated from a 'sorted' stored procedure so the "SelectedIndex" does not match the actual index of the selection.
I have found lots of posts saying use the "ListView" control, but none of them actually show examples of how to bind the control to a data control to acheive what I need.What I am after is a turorial showing ADO code (because I want to hard code this to get a better understanding of how it all works) binding a multi-column control to a SQL database.
When I implement this code, the first time the button is activated, the values are placed in the array, and displyed in the list box. However if the user then selects more days and times to add to the list box, and activates the button again, the previously added entries in the array are erased, and only the new entries are displayed. How can I prevent previous entries from being erased? If the user wants to add values, they need to be added to the existing values.[code]
