why not escape to catch an error when i next run?

Question

I have the following code structure:

[CODE]

bool bStop = true;

int RowCount = 65000;

private void btnRun_Click(object sender, EventArgs e)

{

int i = 0;

//int iErr;

while (i < dataGridView1.Rows.Count - 1 && bStop)//Loop 1

{

while (i < dataGridView1.Rows.Count - 1 && bStop)// Loop 2

{

try

{

if (i > 0) dataGridView1.Rows[i-1].Selected = false;

dataGridView1.Rows[i].Selected = true;

dataGridView1["ROWS", i].Value = "Processing...";

System.Windows.Forms.Application.DoEvents();

Thread.Sleep(1000);

Debug.Print("are in Try and i: " + i);

//if (chkErr.Checked == true)

//{ iErr = "E"; }

}

catch (Exception ex)

{

Debug.Print("are in Catch and i: " + i + " ex: " + ex.Message);

//If an error occurs this place, why not escape to run i next catch ?

}

i++;

}// Loop 1

}//Loop 2

}

[/CODE]
