I am working in VB 2008 and I have set up a datagridview to display rows of data which can then be selected. When I select the first row I get the error: Index was out of range. Must be non-negative and less than the size of the collection. When I select any other row the program executes as it should. From what I have learned so far is that the DataGridView has an index of -1 and that it counts the header row as part of the index which is the -1.When I select the first row through either DataGridView1_RowHeaderMouseClick or DataGridView1_CellContentClick the index is 0 for the first record. If the index is 0 I think it would fire off, but I have no idea what is happening behind the scenes. I can check the index, so when it is 0 and the code attempts to access the row, that is when I get the message.On an index number of 1 and up the code executes fine.So, is there a way to re-index the DataGridView, or is there a work around/fix for this issue?

I have a datagridview, with 3 columns, each containing dropdown filters (in the column header). Of the 3 columns, 2 are working perfectly fine, but whenever I try to filter the 3rd column, it gives me this error: (Also all of the column's have the ColumnType property set to: DataGridViewAutoFilterTextBoxColumn) "Index was out of range. Must be non-negative and less than size of the collection. Parameter name: index." The error points to the part that begins with "If dgv1.Rows(e.RowIndex)..."

It works fine when I step through it with F8, but when running normally, I guess it's going so fast that I get an Index out of range when the outer For loop increments to the second iteration. I tried putting a timer in there to give it a chance to update the UI, but that didn't work. I also tried "Application.DoEvents" as a last resort, and that didn't work either.
I'm trying to grab the values that have changed using the GridView_RowUpdating event.

Weird thing is, it seems to pull OldValues fine, but when I try to pull the NewValues I get an "Index was out of range." Checking around I see that this sometimes occur if you have non-BoundFields in your Gridview, but all of my fields are bound!
