You can combine the search as follows:

SQL

ssql = "select iname,itmcode,ivalue,balqty from vewhelp where (itmcode like '%" & Trim(Me.txtsr.Text) & "%' OR iname like '%" & Trim(Me.txtsr.Text) & "%')  and site='" & loginsite & "' and left(itmcode,2)='" & storeID & "'"

If you pass the data directly without validation, you are prone to SQL injection. Use parametrized queries. Example:

Combine the SQL stagtement with an OR operator

Private Sub btngo_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btngo.Click
        Try
            
            With fg
                Dim str(1) As String
                ssql = Nothing
                If fg.Col = 1 Then
                    ssql = Nothing
 
                    ssql = "select iname,itmcode,ivalue,balqty  from vewhelp where (iname like '%" & Trim(Me.txtsr.Text) & "%' or itmcode like '%" & Trim(Me.txtsr.Text) & "%') and site='" & loginsite & "' "
                End If
                fn.readqry(ssql)
                Dim dr As SqlDataReader = cmd.ExecuteReader()
                fg.Rows.Count = 1
                fg.Rows.Count = 2
                While dr.Read()
                    .SetData(.Rows.Count - 1, "iname", dr.Item("iname"))
                    .SetData(.Rows.Count - 1, "rate", dr.Item("ivalue"))
                    .SetData(.Rows.Count - 1, "balqty", dr.Item("balqty"))
                    .SetData(.Rows.Count - 1, "icode", dr.Item("itmcode").ToString())
                    .Rows.Count += 1
                End While
                dr.Close()
 
                fg.Focus()
 
            End With
 

        Catch Excep As Exception
            MessageBox.Show(Excep.Message, "Error,Contact OR Send ()", MessageBoxButtons.OK, MessageBoxIcon.Error)
        End Try
    End Sub
