在GridView数据源为空时也显示表头_[Asp.Net教程]

if (gridView.DataSource is DataTable
&& ((DataTable)gridView).DataSource).Rows.Count == 0)
{
DataTable dt = new DataTable("EmptyTable");
foreach (DataControlField field in gridView.Columns)
{
if (field is BoundField)
{
dt.Columns.Add(((BoundField) field).DataField);
}
}
ArrayList values = new ArrayList();
for (int i = 0; i < dt.Columns.Count; i++)
{
values.Add(null);
}
dt.Rows.Add(values.ToArray());

gridView.DataSource = dt;
gridView.DataBind();
}
