Fetching Node Collection and Children using CSOM in Sharepoint 2013
After a long Head banging, I found some solution for reading Node collection and its childs. :)
I'm not able to find any ready solution in Online. Hope it will be useful for you. Happy coding. :)
The following Code helps you for Fetching Node Collection and Children using CSOM in Sharepoint 2013.
using (ClientContext SourceSiteClientContext = new ClientContext(SourceSite))
{
//// Get the context for the SharePoint Site to access the data
using (ClientContext TargetSiteClientContext = new ClientContext(TargetSite))
{
Web SourceWeb = SourceSiteClientContext.Web;
Web TargetWeb = TargetSiteClientContext.Web;
List
NavigationNodeCollection SourceSiteTopNavigationColl, TargetSiteTopNavigationColl;
//Tries for Connecting Source Site with NTLM and if fails connects with Sharepoint online Method
try
{
Console.WriteLine("Connecting Source Site - " + SourceSite);
Console.WriteLine("Connecting with NTLM Method..");
SourceSiteClientContext.Credentials = new NetworkCredential(SourceSiteUserName, SourceSitePassword, SourceSiteDomain);
//// Get the collection of navigation nodes from the top navigation bar
SourceSiteTopNavigationColl = SourceWeb.Navigation.TopNavigationBar;
SourceSiteClientContext.Load(SourceSiteTopNavigationColl);
SourceSiteClientContext.ExecuteQuery();
}
catch
{
Console.WriteLine("Connecting with Sharepoint Online Method ..");
SecureString SourceSiteSecurePwd = convertToSecureString(SourceSitePassword);
SourceSiteClientContext.Credentials = new SharePointOnlineCredentials(SourceSiteUserName, SourceSiteSecurePwd);
//// Get the collection of navigation nodes from the top navigation bar
SourceSiteTopNavigationColl = SourceWeb.Navigation.TopNavigationBar;
SourceSiteClientContext.Load(SourceSiteTopNavigationColl);
SourceSiteClientContext.ExecuteQuery();
}
//Tries for Connecting Target Site with NTLM and if fails connects with Sharepoint online Method

Console.WriteLine("Connecting Target Site - " + TargetSite);
Console.WriteLine("Connecting with NTLM Method..");
