delete entrys from drop down

gristy — Thu, 06 May 2010 07:46:51 GMT

Hi Guys,

i have the following code that populates a drop down, it works fine, but id like to refresh entrys in the drop down via a button, however i get mixed results when re-reunning it so id like to add to this code to clear all existing entrys in the drop down first. Could someone please help.

SPList sm = web.Lists["Scope Management"];

SPListItemCollection smi = sm.Items;

XPathNavigator xPathNav = MainDataSource.CreateNavigator().SelectSingleNode("/my:myFields/my:SectionA/my:ProjectProposal/my:projectproposals", NamespaceManager);

xPathNav.SelectSingleNode("/my:myFields/my:SectionA/my:ProjectProposal/my:ddProjectProposal", NamespaceManager).SetValue("");

XPathNavigator Loc = xPathNav.SelectSingleNode("/my:myFields/my:SectionA/my:ProjectProposal/my:projectproposals", this.NamespaceManager);

Loc.SetValue("");XPathNavigator templateNode = Loc.Clone();

foreach (SPListItem i in smi)

{

String Name = i.Name;

XPathNavigator newNode = templateNode.Clone();

newNode.SetValue(Name);

Loc.InsertAfter(newNode);

}

Loc.DeleteSelf();

Code
