Hello,
I'm going around in circles with this problem and I hope someone can help me.
I have a listbox that is populated from a SQL Server database, with about 600 items, all strings.
I have a textbox on the same form, where I want to display which item is selected.
In the 'OnSelectedIndexChanged' event, I need code that has the textbox update to whatever value is currently selected in the listbox.
If I use the code:
TextBox1.Text = ListBox1.SelectedItem.toString
it diplays the incorrect item in the textbox.
If I use a datarow view with the following code:
Dim drv As DataRowView = lBoxCP.SelectedItem
txtCPMain.Text = drv("STR_CUTTING_PERMIT")
It works quite well, but after clicking several different items, the text box starts showing incorrect items.
SelectionMode is set to One.
Any suggestions?
Thanks,
Amber

Hi,
Try binding the textbox and the listbox to the same datasource. The
currency manager will keep them in sync.

Hi Amber,
Are you sure you use the protected event 'OnSelectedIndexChanged' because
than I think you have to show some code to give us an idea what you are
doing.

It is bound to the same dataset, isn't it? Here's my code
The list box is 1st populated by this code
Private Sub get_all_CPs(
lBoxCP.DataSource = Nothin
lBoxCP.Items.Clear(
lBoxCP.Refresh(
DsCP1.Clear(
SqlDA_CP.Fill(DsCP1
Dim dvCP As DataVie
dvCP = New DataVie
With dvC
.Table = DsCP1.Tables("TDT_CUTTING_PERMIT"
.Sort = "STR_CUTTING_PERMIT
End Wit
lBoxCP.DataSource = dvC
lBoxCP.DisplayMember = "STR_CUTTING_PERMIT
lBoxCP.Refresh(
End Su
And here's the listbox event code
Private Sub lBoxCP_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handle
lBoxCP.SelectedIndexChange
Dim drv As DataRowView = lBoxCP.SelectedIte
txtCPMain.Text = drv("STR_CUTTING_PERMIT"
End Su
Thanks

Hi Amber,
That is what I thought it is the
SelectedIndexChanged not OnSelectedIndexChanged, which exist also
However when you add that one row I did you can delete that complete event
in my opinion
\\\
lBoxCP.DataSource = dvCP
lBoxCP.DisplayMember = "STR_CUTTING_PERMIT"
txtCPMain.Text.DataBindings.Add(Text",dvCP,"SRT_CU TTING_PERMIT")
lBoxCP.Refresh()
///
I do not know if you fill the dataset more and than you can set by the clear
of the dataset
txtCPMain.Text.Databindings.clear
I hope this helps?

Hi,
Instead of setting the value in the selected index changed event
try this.
Private Sub get_all_CPs()
lBoxCP.DataSource = Nothing
lBoxCP.Items.Clear()
lBoxCP.Refresh()
DsCP1.Clear()
SqlDA_CP.Fill(DsCP1)
Dim dvCP As DataView
dvCP = New DataView
With dvCP
.Table = DsCP1.Tables("TDT_CUTTING_PERMIT")
.Sort = "STR_CUTTING_PERMIT"
End With
lBoxCP.DataSource = dvCP
lBoxCP.DisplayMember = "STR_CUTTING_PERMIT"
lBoxCP.Refresh()
txtCPMain.DataBindings.Add("Text", dvCP, "STR_CUTTING_PERMIT")
End Sub
