When you use an instance of the Microsoft.SharePoint.WebControls.DateTimeControl in SharePoint (for example in a webpart), the locale will always be set to en-US, even if the web of user have specified a different locale.

To overcome this, you need to explicitly set the LocaleId property of the control to the correct locale.

DateTimeControl dtCtrl =new DateTimeControl();
dtCtrl.ID = "dtCtrl";
dtCtrl.LocaleId = (int)SPContext.Current.RegionalSettings.LocaleId;
this.Controls.Add(dtCtrl);

You should use SPContext.Current.RegionalSettings as this reflects the RegionalSettings for the current user (they might differ from the Web if the user modified this).

Microsoft Sharepoint Server 2007 lookup control with element picker for custom list.
This control is useful if you need to choose lookup data from large lists. This control supports single and multi select mode.

You can get an SPListItemCollection from a List using a View with the following code:

SPList list = SPContext.Current.Web.Lists["My List"];

SPListItemCollection items = list.GetItems(list.Views["All Items"]);

When then try to access the Title field of any of the individual SPListItem instances in the collection you will receive an ArgumentExecption

//all these statements will throw an Argument Exception
string titleField = item[0]["Title"];
string titleProperty = items[0].Title;
string titleValue = items[0].GetFormattedValue("Title");

As a workaround, you can access the Title field value using the LinkTitle field:

//this will return the correct value
string title = items[0].GetFormattedValue("LinkTitle");
