Find A Certain String Within Listbox?
Sep 7, 2010
I have a list box with groups of people and is displayed as such:
Paul Mary John
Frank Steve Bill
Jacob Dan Spongebob
and so on...
If i use the code below i can find and auto highlight Paul, Frank, Jacob but never finds anyone after the first like Mary, or Bill.
Dim findperson As String
findperson = CStr(TextBox1.Text)
ListBox1.SelectedIndex = ListBox1.FindString(findperson)
Essentially it is for quick reference for people to find who will be in their groups.

Then skips straight to the Else without performing the two lines in between, regardless of whether the item was checked or not checked. It doesn't crash, doesn't throw any errors, so I am assuming I coded this wrong somehow.

I have a listbox which on form load generates correctly from a text file like so in a listbox...ex"John Doe, 1""Bob Brown,2"I now would like to search the listbox if it contains either a "1" or a "2" which is does in this case and copy the item to another listbox. The 1 and 2 indicate positions I have a position listbox for each position. So 3 listbos, first one contains the names on form load, 2 other empty listboxes one for position 1 other for position 2...I have tried the following
If xReservationListBox.SelectedIndex = xReservationListBox.FindString("1") Then
'MessageBox.Show("Found It")
xSpot1ListBox.Items.Add(xReservationListBox.Items(0))
[code].....

I have a listbox where each line contains a short 3-4 character model number followed by a tab and then the product name the model number corresponds to. I also have a textbox which I am using to search the listbox.
The code I am using so far works somewhat, just not exactly how I would like. If I enter search text it will highlight the results in the listbox but only for the first characters, is there anyway to search the text of an entire line (index) of a listbox?
Right now I am using the following:
Private Sub txtSearch_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txtSearch.TextChanged
ListBox.SelectedIndex = ListBox.FindString(txtSearch.Text)
End Sub

I need to find a method of looping through a listbox and retrieving the index number and values - quite straightforward in asp, but turning out to be something of a nightmare in winforms!Here is the scenario - The user can add values in a textbox, that are in turn added to a DataTable that gives it a unique ID and a row number, this is then bound to the listbox. The user can then move the items up or down the list by adjusting the row number in the datatable and rebinding to the listbox..
The problem that I am hitting is when the user needs to delete an item -the first part is easy - delete from the DataTable and rebind to the listbox. The bit where I hit the proverbial brick wall is needing to loop through the listbox rows and getting both the index number and the ValueMember - that way I can change the row numbers in the DataTable based on the index number against the ID number.
