I'm new in the vb.net environment as I'm used to coding in c#. I've copied the DataGridViewPrinter class to my project as I want to print the contents of my datagridview but I now get an error stating :

"Type 'DataGridView' is not defined" in the line below:

VB

Private TheDataGridView As DataGridView

Can someone please help? I need to finish this by tomorrow Afternoon.

Thank you in advance.

Do you have the following import?

Imports System.Data

Why would he need that for a DataGridView, which is in the Windows.Forms namespace?

My mistake, confused it with DataTable...sorry

Hi Ryan

Yes I do have it and it's not helping. Any other suggestion?

As Minute said, DataGridView is in the Windows.Forms namespace, so you should try Imports System.Windows.Forms

Hi Ryan and Minute

I have tried what u both suggested and it now gives me an error stating the following:

Namespace or type specified in the Imports 'System.Windows.Forms' doesn't contain any public member or cannot be found.Make sure the namespace or the type is defined and contains atleast one public member.Make sure the imported element doesn't use any aliases.

That error message sounds like you need to add a reference to Windows.Forms in your project.

Right click on the project in Solution Explorer, select Add Reference menu item then you should be able to work the rest out for yourself. :)

Thanks a lot Minute. I've tried what u suggested and it works however I now want to call my class in the button print event handler method and I get the following error :
" Type 'DataGridViewPrinterHelper' is not defined".

Here's my code below:

Protected Sub btnPrint_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnPrint.Click

Dim Printer = New DataGridViewPrinterHelper
Printer.Title = "Production Facilities Systems"
Printer.SubTitle = "Maintaning Reports"
Printer.PageNumbers = True
Printer.PageNumberInHeader = False
Printer.ProportionalColumns = True
Printer.HeaderCellAlignment = StringAlignment.Near
Printer.Footer = My company name"
Printer.FooterSpacing = 15
Printer.PrintDataGridView(Me.grdResults)

Please help

Please use the 'Add Comment' rather than adding an answer. That way the answerer will get an Email that you have done so.

BTW: DataGridView lives in the Windows.Forms namespace NOT in System.Data so if your problem is a missing Import, that is the one you need.
