how to make search between pages

Can you clarify which application you are using? Is it VB6 as the topic 'Visual Basic Classic' would suggest?
It would help to post your code.

Hmm.
>>each page contains same data table
>>search all pages,all data tables
Do you have 1 or 5 datatables? According your photo you have only one BindingSource. In this case code should be smth like this

Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
    Dim idx = Solina1BindingSource3.Find(YourStringColumnName, "Whatever1")
    'or Dim idx = Solina1BindingSource3.Find(YourIntegerColumnName, 5)
    If idx >-1 then Solina1BindingSource3.Position = idx
End Sub

Select all Open in new window

Karolina,
It is better to send a screen capture instead of a photograph. You can get this on one of two ways.
You can put the picture into the Windows clipboard by pressing the PrintScrn button. Then you can open Windows Paint and paste into a new image.
Alternatively you can use the Windows Snipping tool. The allows you to select and copy only a part of the whole screen.

(I can't help with you particular problem as I am only a novice with VB.Net.)

1. Is there same criteria to search for each datatable or there are different criteria for each?
2. Are you binding data with bindingsource for each datatable?
