Row Delete From DataGridView?
Nov 23, 2009I'm new to VB and using a datagridview for the first time. I've spent the last 2-3 days trying to get row deletion to work and can't do it.

Clicking it will delete the row from the DGV, but the changes are not going back to the database. Here is the code I'm using right now in my delete button event handler:

FormLoad - Cannot Delete Row From DataGridView
Mar 31, 2009I am using VB 2008 .net3.5. I have a form with a datagridview. The datasource of the dgv is a BindingSource. The datasource of the binding source is an object and the datamember of the binding source is a List(Of T) from that object. On formload, I create a new object with new and give the list some values and Set the datasource of the binding source to the list. The dgv loads the data but I can't delete a row. The AllowUserToDeleteRows is set to true. I select a row and nothing happens. Just to be sure I went back and did the EXACT SAME PROGRAM with C# .net2.0 and of course the dgv allows me to delete a row.
