[RESOLVED] DataGridView not painting itself correctly

I have this code:

Code:

---

private void GetErrors()
{
    errors = GetFailedTasks();

    for (int i = 0; i < errors.Count; i++)
    {
        Task t = errors[i];
        if(gridAlerts.Rows.Count <= i)
            gridAlerts.Rows.Add(new DataGridViewRow());
        gridAlerts["_ID", i].Value = t.ID;
        gridAlerts["_Severity", i].Value = t.Severity;
        gridAlerts["_Customer", i].Value = t.Customer;
        gridAlerts["_Unit", i].Value = t.Unit;
        gridAlerts["_IP", i].Value = t.IP;
        gridAlerts["_Type", i].Value = t.Type;
        gridAlerts["_Limit", i].Value = t.LimitString;
        gridAlerts["_Time", i].Value = t.TimeString;
        gridAlerts["_Message", i].Value = t.Message;

        switch (t.DownColor)
        {
            case "red":
                gridAlerts["_Severity", i].Style = red;
                break;
            case "yellow":
                gridAlerts["_Severity", i].Style = yellow;
                break;
            case "green":
                gridAlerts["_Severity", i].Style = green;
                break;
        }
    }

    for (int i = gridAlerts.Rows.Count - 1; i >= errors.Count; i--)
        gridAlerts.Rows.RemoveAt(i);
}

which is executed every 2 seconds on my form. Whenever the code adds or removes one or more rows, it ends up looking like this:

I've tried:

Code:

---

gridAlerts.UpdateCellValue(cell, row);
gridAlerts.Update();
gridAlerts.CommitEdit();

---

But nothing has made any difference.

The point of manipulating the rows like this is to maintain the scrollbar position...

Does anyone have a suggestion? :)

Solved: The datagridview's defaultcellstyle contained some transparent colors, which were the cause of the problems
