Namespace: DevExpress.XtraTreeList

Assembly: DevExpress.XtraTreeList.v21.2.dll

Declaration

public virtual void RestoreLayoutFromStream(
    Stream stream
)

Parameters

Name Type Description
stream Stream

A System.IO.Stream object from which the control’s settings are read.

Remarks

Use the RestoreLayoutFromStream method to load the control’s layout from a stream to which a layout was saved via the TreeList.SaveLayoutToStream method call.

The Tree List options that are restored are identified by the TreeList.OptionsLayout object.

Note

When restoring a layout during a form load (for instance, in your Form.Load event handler), you may need to call the TreeList.ForceInitialize method prior to the layout restoration. See this method to learn more.

Example

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.

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();
