Hello everyone.I have a problem with reading data from DataGridView to array. Use code:
....
What I do wrong?
At first please use codetags,( thats what you do wrong here in this forum ) So please edit your post. Without codetags code losts formatting.
we do not know if your grid contains integers. Are you sure ? maybe it contains strings, so what contains your grid. Please show a screenshot maybe so we can see

Using Code Tags makes the difference: Code is easier to read, so its easier to help. Do it like this: [CODE] Put Your Code here [/code]
If anyone felt he has got help, show it in rating the post.
Also dont forget to set a post which is fully answered to 'resolved'. For more details look to FAQ's about Forum Usage. BTW I'm using Framework 3.5 and you ? My latest articles : Creating a Dockable Panel-Controlmanager Using C#, Part 1 | Part 2 | Part 3 | Part 4 | Part 5 | Part 6 | Part 7
int[,] n = new int[3, 19];
for (int i = 0; i < (StartDataView.Rows.Count - 1); i++)
{
for (int j = 0; j < StartDataView.Columns.Count; j++)
{
try
{
n[i, j] = int.Parse(this.StartDataView.Rows[i].Cells[j].Value.ToString());
}
catch (Exception Ee)
{ //get exception of "null"
MessageBox.Show(Ee.ToString());
}
}
}

I tested your code in the added project and as you will see it works.
So the problem must be elsewhere maybe in the databinding itself ?
