If you're looking to default to 0 on an empty textbox:

int i = string.IsNullOrEmpty((SoccerTable.FooterRow.FindControl("txtAchNumsFooter") as TextBox).Text.Trim()) ? 0 : int.Parse((SoccerTable.FooterRow.FindControl("txtAchNumsFooter") as TextBox).Text.Trim());

If you're looking to default to 0 with any bad formatted input:

int i;
if (!int.TryParse((SoccerTable.FooterRow.FindControl("txtAchNumsFooter") as TextBox).Text.Trim(), out i)) i = 0;
