My datagridview only contains one column which is filled with rows containing data like '2,, 1000, Supplier,40000,,7/31/2013'. Is there a way to split the values in each row from the datagridview and put them into Dim Data As New List(Of String()). Add a serial no to datagridview column and. Rows() is derived from dt and is array of. Your record may now have a different 'serial number.

Let's work to help developers, not make them feel stupid. Here is a method to auto number using a DGV that is not bound to a data source. The code places the auto numbering in column zero. Place a DataGridView on the form and add the desired number of columns. Vb Net Array InitializeAdd a button. In an attempt to keep this post as short as possible, I will assume that you are familiar with Microsoft SQL 2005 Express and you will be using it to create your data tables. If you need guidance on how to use it, I would suggest you watch a series of videos presented by Beth Massi. Here is a link: The “Forms Over Data Series' starts about 2 thirds of the way down the page. Microsoft keep moving these videos around and it can sometimes take quite a bit of effort to find them. I suggest you download and keep them for future reference. I have used Visual Basic Express 2008 for this demonstration. Now to the help that you requested. Open Visual Basic and create a project. Add a data source to it consisting of a table with 2 columns. The first column is the primary key (an integer) and remember to set the “Identity Specification”. The second column will display the auto numbering which I also set to “integer” as it will be taking whole numbers for your auto numbering. I have called my table “Numbers” and the dataset is “Test”. I use the lazy man’s way of putting the DataGridView on the form by dragging it from the data source. This shows all of the columns in the DGV which includes the primary key making the first user column number 1. You can always remove the primary key column from the display which will make the first user column zero. Array In Vb NetIf you do this, remember to modify the code to cater for the change. If you have done this correctly, you will have a form with a DataGridView and a Binding Navigator at the top of the form. Now add a button to the form. Leave the default name as “Button1” With the code provided, you will increase the auto numbering value in the grid.
