Listview to textbox
Hi Experts,
I am tired of punding my head in, so I am turning to the "guru's". I have a listview that is populated at load from a database; this listview has five columns. I want to (on click of checkbox) fill a textbox with the contents of column five of the selected record.
Example:
PersonType_ID PersonNumber Offense_Indicator FullName person_id
W W-1 1,2,3 Joe N. Smith 99999
In the above example I need for the textbox to be filled with the 99999. How can I make this happen? Below is my current "LOAD" code for the form:
Private Sub OffenseIncidnetPeopleEditA
GroupBox1.Text = "Offenses for Agency Report Number: **********"
Dim conn2 As New System.Data.SqlClient.SqlC
Dim da2 As New System.Data.SqlClient.SqlD
Dim ds2 As New System.Data.DataSet
Dim loggedOnUser As String
loggedOnUser = My.User.Name
Dim cmd2 As New System.Data.SqlClient.SqlC
Dim cmd As New System.Data.SqlClient.SqlC
Try
conn2.Open()
Dim myReader As SqlDataReader = cmd.ExecuteReader()
Do While myReader.Read()
Dim lvi As New ListViewItem(myReader.Item
lvi.SubItems.Add(myReader.
lvi.SubItems.Add(myReader.
lvi.SubItems.Add(myReader.
lvi.SubItems.Add(myReader.
ListView1.Items.Add(lvi)
Loop
myReader.Close()
Catch ex As Exception
MessageBox.Show(ex.Message
Finally
conn2.Close()
End Try
End Sub

I have tried this and I get the following error:
InvalidArgument=Value of '0' is not valid for 'index'.
Parameter name: index
InvalidArgument=Value of '0' is not valid for 'index'.
Parameter name: index
Private Sub ListView1_Click()
my_SELECTED_ROW = ListView1.SelectedItem.Ind
LR= ListView1.ColumnHeaders.Co
tmp = ListView1.ListItems(my_SEL
Text1.Text = tmp
End Sub
my_SELECTED_ROW = ListView1.SelectedItem.Ind
LR= ListView1.ColumnHeaders.Co
tmp = ListView1.ListItems(my_SEL
Text1.Text = tmp
End Sub
you probably have not item selected on the first run so without selecting a row
selected items will be empty then you need to pass in a index yourself
TextBox1.Text = ListView1.Items(0).SubItem
selected items will be empty then you need to pass in a index yourself
TextBox1.Text = ListView1.Items(0).SubItem

vb_elmer,
That didn't work either. I forgot to mention, I am using VB2005

are you selecting an item in the load fucntion or not?
ASKER
no, at load the listview is filled from a database, I am selecting checkboxes
but i don't understand the sequence
1. you fill the listview
2. then click on a checkbox (in the listview?)
3. and the text box should show the subitemtext
or is there a step to select a row first

1. Form loads
2. onLoad the listview fills
3. click checkbox on listview
4. textbox show the data in column 5

uaahhh .
uaahhh .
The DataGridView control in vb2005 is excellent and far superior to the old datagrid of .net1.x and may be a better and easier replacement to your listbox.
Then all youd need to do would be to load the dataset set using a dataadaptor instead of a command reader and Bind it to the DataGridView (the DataGridView is easy to set as readonly or additional behavioru for each column action unlike the old DataGrid) (actuall recommed binding it via a DataView control for easy readonly setting) and catch the currentcellchanged event and check if is column 4 (5-1) and react accordingly...

oh youd probably want to set RowselectMode = true to make it look a little more like a list box (and even more so if you removed the side and top headers and sett the gridcolumn colour to systemcolor.window)
----------
you can try
TextBox1.Text = ListView1.SelectedItems(0)
not sure now if the subitems are starting at zero also so it could be
TextBox1.Text = ListView1.SelectedItems(0)
