listbox problems

hi there

i have three listboxes on my form

lstES, lstNES, lstGC

actually all the three listboxes are aligned one next to the other
The listboxes contains different subjects in each one of them

Actually when i am selecting an item in any one of the listboxes, i wish to have the selected index = -1 in the other two listboxes.

i have tried different codes, but i couldnt possibly make it out. Can anyone help me plz.

Thanks

write code in Validated event of all list boxes.

In 1st ListBox:
LB2.SelectedIndex =-1
LB3.SelectedIndex =-1

In 2nd ListBox:
LB1.SelectedIndex =-1
LB3.SelectedIndex =-1

In 3rd ListBox:
LB1.SelectedIndex =-1
LB2.SelectedIndex =-1

hope is helps

Regards

i mentioned it. In "Validated" Event. Or maybe there's something like "IndexChanged"

I tried it in almost all the events that i could possibly find as being a one that will make it work, but still i couldnt do it

Could anyone help plz.

i tried on validated, indexchanged, mousedown, mouseup but didnt work

Thanks

halu,

i don't know if i understand the prob correctly but just as pvbangera mentioned, you have to specify for each event.
mousedown is working for this...

VB Code:

Private Sub ListBox1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListBox1.MouseDown
        ListBox2.SelectedIndex = -1
        ListBox3.SelectedIndex = -1
        TextBox1.Text = ListBox1.SelectedIndex
        TextBox2.Text = ListBox2.SelectedIndex
        TextBox3.Text = ListBox3.SelectedIndex
    End Sub
 
    Private Sub ListBox2_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListBox2.MouseDown
        ListBox1.SelectedIndex = -1
        ListBox3.SelectedIndex = -1
        TextBox1.Text = ListBox1.SelectedIndex
        TextBox2.Text = ListBox2.SelectedIndex
        TextBox3.Text = ListBox3.SelectedIndex
    End Sub
 
    Private Sub ListBox3_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListBox3.MouseDown
        ListBox1.SelectedIndex = -1
        ListBox2.SelectedIndex = -1
        TextBox1.Text = ListBox1.SelectedIndex
        TextBox2.Text = ListBox2.SelectedIndex
        TextBox3.Text = ListBox3.SelectedIndex
    End Sub

i just put something like 3 textboxes to monitor their corresponding selected index values...

hope this helps... if not, sorry for bothers...
