我总是收到这个错误：
mscorlib.dll中发生了'System.ArgumentOutOfRangeException'类型的异常但未在用户代码中处理
其他信息：指数超出范围。必须是非负面的 并且小于集合的大小。
在我的代码的这一部分：
GridViewRow gvrow = GridView1.Rows[index]
我不知道发生了什么......
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
int index = Convert.ToInt32(e.CommandArgument);
if (e.CommandName.Equals("detail"))
{
string id = GridView1.DataKeys[index].Value.ToString();
IEnumerable<DataRow> query = from i in dt.AsEnumerable()
where i.Field<String>("id").Equals(id)
select i;
DataTable detailTable = query.CopyToDataTable<DataRow>();
DetailsView1.DataSource = detailTable;
DetailsView1.DataBind();
System.Text.StringBuilder sb = new System.Text.StringBuilder();
sb.Append(@"<script type='text/javascript'>");
sb.Append("$('#detailModal').modal('show');");
sb.Append(@"</script>");
ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "DetailModalScript", sb.ToString(), false);
}
else if (e.CommandName.Equals("editRecord"))
{
GridViewRow gvrow = GridView1.Rows[index];
lblPTAID.Text = HttpUtility.HtmlDecode(gvrow.Cells[3].Text).ToString();
