How to pass data from Listbox to a textbox

Hello,

I am using the code below to pass data from my testbox to a list box, How do I pass the data from my listbox to a textbox separated by a (;).

C1NSN.Text = dtNSN.Rows(0).Item("NSN")
Dim tmp() As String = C1NSN.Text.split(";")
For i As Integer = 0 To tmp.Length - 1
ListBox1.Items.Add(tmp(i))
Next

Thanks,

Victor

Try something like this:

C1NSN.Text = ""
For i = 0 to listbox.items.count-1
   C1NSN.Text = C1NSN.Text & ";" & ListBox1.Items(0).Text
next i

Open in new window

Hope it helps

Do:

For x = 0 To LBox.Items.Count - 1
    C1NSN.Text = If(String.IsNullOrEmpty(C1NSN.Text.ToString.Trim), LBox.Items(x), C1NSN.Text & ";" & LBox.Items(x))
Next

Thank you, I will try them and get back you. How do I accomplish the same with all the rows in a GridView?

Hi,

I tried both of them but it is still not working, the following code:

C1NSN.Text = ""
For i = 0 to listbox.items.count-1
C1NSN.Text = C1NSN.Text & ";" & ListBox1.Items(0).Text
next i

Gives me the data of the first row multiple times, for example if my list box contains

AAAAA
BBBBBB
CCCCCC

My textbox shows:
AAAAA
AAAAA
AAAAA

The following code:

For x = 0 To LBox.Items.Count - 1
C1NSN.Text = If(String.IsNullOrEmpty(C1NSN.Text.ToString.Trim), LBox.Items(x), C1NSN.Text & ";" & LBox.Items(x))
Next

Give me error message:

Operator '&' is not defined for types 'String' and 'System.Web.UI.WebControls.ListItem'.

get the listbox item text instead

For x = 0 To ListBox1.Items.Count - 1
    C1NSN.Text = If(String.IsNullOrEmpty(C1NSN.Text.ToString.Trim), ListBox1.Items(x).Text, C1NSN.Text & ";" & ListBox1.Items(x).Text)
Next

Happy to know it worked. Sorry, I haven't work with gridview. I suggest to open another question for this and add the code you have on this new question.
