will you pls. explain a little bit broad on your problem.

is this master-detail relationship?
listbox1 is the master and listbox2 are the details?

At first both listbox is enabled and can be choose if something is inside..

But if i choose either of the listbox....the other will automatic be disabled... that means i should not select from both listbox at the same time...

Then when i click on another button both listbox will be enable again...

just does not want both to be selected at the same time when only one is being selected first ..

Thanks

VB Code:

Private Sub ListBox1_MouseUp(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListBox1.MouseUp
        ListBox2.Enabled = False
     End Sub
 
    Private Sub ListBox2_MouseUp(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListBox2.MouseUp
        ListBox1.Enabled = False
     End Sub
 
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        ListBox1.Enabled = True
        ListBox2.Enabled = True
    End Sub

here try this one.

VB Code:

Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
        ListBox1.Enabled = True
        ListBox2.Enabled = True
    End Sub
 
    Private Sub ListBox1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListBox1.MouseDown
        If e.Button = MouseButtons.Left Then
            ListBox2.Enabled = False
        End If
    End Sub
 
    Private Sub ListBox2_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListBox2.MouseDown
        If e.Button = MouseButtons.Left Then
            ListBox1.Enabled = False
        End If
    End Sub

Thanks it works...

But how to make the highlight thing disappear when one items is being choosen and reset...

add this in the button event:
ListBox1.SelectedIndex = -1
ListBox2.SelectedIndex = -1
:afrog:

Thanks everyone....

Both methods works well..

:wave:

cheers us all :thumb:

Another quick problem...

How to tell the listbox if i select the items form either listbox...

That means if i select the item in either listbox, the items should be able to appear in TextBox1...

try this one.

VB Code:

Private Sub Lstb_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged, ListBox2.SelectedIndexChanged
        If sender.name = "ListBox1" Then
            TextBox1.Text = ListBox1.SelectedItem
            Exit Sub
        Else
            TextBox1.Text = ListBox2.SelectedItem
            Exit Sub
        End If
    End Sub

:afrog:

what is your Lstb refer to...

listbox1 or listbox2..

Thanks

It can works.....

but it skip my button...

That means if i click on the listbox, it will appear in the textbox without having to click the button....

Thanks

refer to the listbox1 and listbox2 that it is...both of it will trigger but i have a condition their that will trap each of it (sender.name) on what listbox you selected...
in other way, you can use this...

VB Code:

Private Sub ListBox1_SelectedIndexChange(ByVal sender As Object, ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged
and
Private Sub ListBox2_SelectedIndexChange(ByVal sender As Object, ByVal e As System.EventArgs) Handles ListBox2.SelectedIndexChanged

hope it helps :afrog:

what are you trying to achieve? you mean that after the button event then the selected items in the listbox will appear in the textbox, is that? or i am misleading. :bigyello:

yeah....

i want the event to occur only after i click on the button...

For the code that you given, it will automatic appear to the textbox....

forget to mention it before posting the question...
:rolleyes:


Thanks

this one, hopes got it :bigyello:

VB Code:

Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
        If ListBox1.Enabled Then
            TextBox1.Text = ListBox1.SelectedItem
        ElseIf ListBox2.Enabled Then
            TextBox1.Text = ListBox2.SelectedItem
        End If
        ListBox1.Enabled = True
        ListBox2.Enabled = True
        ListBox1.SelectedIndex = -1
        ListBox2.SelectedIndex = -1
    End Sub

:afrog:

no matters how i ask, you could solve it...

Now all the problems are solve...

Thanks fret
