The following sample code saves layout of the Tree List control to a file stream and then restores it. The TreeList.SaveLayoutToStream and TreeList.RestoreLayoutFromStream methods are used for this purpose.

C#

string fileName = "C:\\TreeListLayout";
System.IO.FileStream outFile = new System.IO.FileStream(fileName, System.IO.FileMode.Create);
treeList1.SaveLayoutToStream(outFile);
outFile.Close();
treeList2.DataSource = treeList1.DataSource;
System.IO.FileStream inFile = new System.IO.FileStream(fileName, System.IO.FileMode.Open);
treeList2.RestoreLayoutFromStream(inFile);
inFile.Close();

VB.NET

Dim FileName As String = "C:\TreeListLayout"
Dim OutFile As New System.IO.FileStream(FileName, System.IO.FileMode.Create)
TreeList1.SaveLayoutToStream(OutFile)
OutFile.Close()
TreeList2.DataSource = TreeList1.DataSource
Dim inFile As New System.IO.FileStream(FileName, System.IO.FileMode.Open)
TreeList2.RestoreLayoutFromStream(inFile)
inFile.Close()
