Question concerning TreeView / Expand Nodes Messages   Related Types This message was discovered on ASPFriends.com 'aspngwebcontrols' list. MacWeb@gmx.de Hi, i got the following question: I am using TreeView to display all departments and employees of our company. When an employee logs on to our intranet, the tree should expand exactly to the employees node and select it automatically. Example for employee Markus: - Company Name +Department 1 +Department 2 -Department 3 - Markus <-- selected node +Department 4 .... the only way i see to solve this problem is to use the GetNodeFromIndex("0.2.0") Method and recursively set the expanded properties of the parent nodes to "true". But is there a more elegant solution for the above mentioned problem? greetinx from germany markus -- GMX - Die Kommunikationsplattform im Internet. http://www.gmx.net Reply to this message...        Rene- Frederic Plain SGkgLCANCiANCkkgdGhpbmsgSSBjb3VsZCBub3QgaGVscCB5b3UgYWJvdXQgdGhpcyBwcm9ibGVt IGJ1dCBJIGhhdmUgYSBxdWVzdGlvbiBmb3IgeW91IDoNCkhvdyBkbyB5b3UgcmV0cmlldmUgdGhl IGlkIG9mIHRoZSBlbXBsb3llZSBvZiB5b3VyIHRyZWV2aWV3ICwgSSB0cmllZCB0byBkbyB0aGUg c2FtZSB0aGluZyB5b3UgZG8gYnV0IHRoZSBvbmx5IHR3byBkYXRhIEkgd2FzIGFibGUgdG8gcmV0 cmlldmUgd2FzIHRoZSBuYW1lIHByb3BldHkgYW5kIHRoZSBub2RlIGluZGV4IHByb3BlcnR5Li4u LiBOb3Qgc28gZ29vZCB0byBwYXNzIGFuIGlkIHRvIGFub3RoZXIgcGFnZSBvciBhbm90aGVyIHN0 YXRlICwgIFJpZ2h0ID8NClRoYW5rIHlvdSAuDQpGcmVkIA0KDQoJLS0tLS1PcmlnaW5hbCBNZXNz YWdlLS0tLS0gDQoJRnJvbTogTWFjV2ViQGdteC5kZSBbbWFpbHRvOk1hY1dlYkBnbXguZGVdIA0K CVNlbnQ6IFRodSA1LzIvMjAwMiAxMDo0OSBBTSANCglUbzogYXNwbmd3ZWJjb250cm9scyANCglD YzogDQoJU3ViamVjdDogW2FzcG5nd2ViY29udHJvbHNdIFF1ZXN0aW9uIGNvbmNlcm5pbmcgVHJl ZVZpZXcgLyBFeHBhbmQgTm9kZXMNCgkNCgkNCgkgDQoNCg= Reply to this message...        Shannon Cornish Hi markus     You could do something like this         TreeNode selectedNode =3D myTreeView.GetNodeFromIndex("0.2.0");         foreach(TreeNode node in myTreeView.Nodes) {             if (node.Nodes.Contains(selectedNode) || (node =3D=3D selectedNode)) {                 node.Expanded =3D true;             }         }     It will loop all the nodes in the collection, checking to see if it contains the 'selectedNode' if it does, or if it is the selected node, it will make it expanded. More elegant, faster? I guess that's up to you to decide. :) Shannon, -----Original Message----- From: Click here to reveal e-mail address [mailto:Click here to reveal e-mail address]=20 Sent: Thursday, 2 May 2002 6:49 PM To: aspngwebcontrols Subject: [aspngwebcontrols] Question concerning TreeView / Expand Nodes Hi,=20 i got the following question: I am using TreeView to display all departments and employees of our company.

You can even store XML in the NodeData property. hth, Mike ----- Original Message ----- From: "Rene- Frederic Plain" <Click here to reveal e-mail address> To: "aspngwebcontrols" <Click here to reveal e-mail address> Sent: Thursday, May 02, 2002 10:09 AM Subject: [aspngwebcontrols] RE: Question concerning TreeView / Expand Nodes [Original message clipped] the name propety and the node index property....
