text length validation
Hi,
I have a problem with validation.
Main idea about txbBILL_NR field validation - the minimum number of characters is 4 to select records.
In case the user enters less than 4 characters in the field by pressing the Select button,
the app must display the warning "At least 4 characters must be entered to select entries!".
Until at least 4 characters have been entered, record selection does not have to take place and the result field must be blank.
So I wrote the code, thinking about validation for textbox and this does not working at all.
I think I have a problem with this row "Me.bsBillGrid.DataSource = WSApplicant.Formated.ServiceApplicant.GetBillGrid(New WSApplicant.WS.ArgsBillGrid() With {.BILL_NR = Me.txbBILL_NR.TextLike}).ToSortableBindingList" with datasource. Can not imagine how would it be right.
Please help me with this validation. is it ok?
Code:
If Me.txbBILL_NR.TextLength >= 4 Then
Me.dgvBill.Visible = True
Try
Search()
If Me.bsBillGrid.Current IsNot Nothing Then
Me.dgvBill.Focus()
End If
Catch ex As Exception
Utility.ExceptionManager.HandleException(ex)
End Try
End If

Re: text length validation
Depends. Where is that code located? If it's in the right place, then it should be reasonably correct...as long as search does what you want, etc. It will only run if the length is four or greater, so that part is right.
My usual boring signature: Nothing
