protected void Page_Load(object sender, EventArgs e)
{
try
{
SPSecurity.RunWithElevatedPrivileges(delegate()
{
using (SPSite oSite = new SPSite(Convert.ToString(ConfigurationManager.AppSettings["WebUrl"])))
{
oSite.AllowUnsafeUpdates = true;
using (SPWeb oWeb = oSite.OpenWeb())
{
oWeb.AllowUnsafeUpdates = true;
SPList oList = oWeb.Lists.TryGetList(ConfigurationManager.AppSettings["WebLists"]);
if (oList != null)
{
SPListItemCollection items = oList.GetItems();
foreach (SPListItem item in items)
{
string Title = Convert.ToString(item["Title"]);
grdEmp.DataSource = Title;
grdEmp.DataBind();
}
}
oSite.AllowUnsafeUpdates = false;
oWeb.AllowUnsafeUpdates = false;
}
}
});
