Ways to expand search bar code? Thanks!!!

Hi all,

I have made a search bar on a userform that will be used for finding data values across the workbook from different worksheets.

So far the search bar can only find values from "Sheet3". I want to modify the code so it can pick up data values from all worksheets in the workbook,

The search bar pickup values regarding to range and displays each row of data within 15 different TxtBoxes.

Below is the code I have used and a screenshot of my user form.

Private Sub btnSearch_Click()
Dim ws As Worksheet
Dim strSearch As String
Dim aCell As Range, v

On Error GoTo Err

'validate text box
v = Trim(TextBox6.Value)
If Len(v) = 0 Then
    MsgBox "Please Enter Data Value."
    Cancel = True
    Me.TextBox6.SetFocus
    Exit Sub
End If

Set aCell = Sheets("sheet3").Range("A:A").Find(v, lookat:=xlWhole)

If Not aCell Is Nothing Then

    With aCell.EntireRow

        TextBox1.Text = .Cells(, "A").Value
        TextBox2.Text = .Cells(, "B").Value
        TextBox3.Text = .Cells(, "C").Value
        TextBox4.Text = .Cells(, "D").Value
        TextBox5.Text = .Cells(, "E").Value
        TextBox7.Text = .Cells(, "F").Value
        TextBox8.Text = .Cells(, "G").Value
        TextBox9.Text = .Cells(, "H").Value
        TextBox10.Text = .Cells(, "I").Value
        TextBox11.Text = .Cells(, "J").Value
        TextBox12.Text = .Cells(, "K").Value
        TextBox13.Text = .Cells(, "L").Value
        TextBox14.Text = .Cells(, "M").Value
        TextBox15.Text = .Cells(, "N").Value
 
       

    End With

Else
    MsgBox "Data Value Not Found."
    Cancel = True
    'frmSearchTest.TextBox6.Value = ""
    TextBox6.SetFocus
End If

Exit Sub

Err:
    MsgBox Err.Description

End Sub
