TreeList.RestoreLayoutFromStream(Stream) Method

SECURITY NOTE

Deserializing layout settings from untrusted resources may create security issues. Review the following help topic for additional information: Safe Deserialization.

Loads the control’s layout from a stream.

Namespace: DevExpress.XtraTreeList

Assembly: DevExpress.XtraTreeList.v24.2.dll

NuGet Packages: DevExpress.Win.Navigation, DevExpress.Win.TreeList

#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();
