csharp

public virtual void RestoreLayoutFromXml(
    string xmlFile
)

Public Overridable Sub RestoreLayoutFromXml(
    xmlFile As String
)

Parameters

Name	Type	Description
xmlFile	String

A string value specifying the XML file from which control settings are read.

Remarks

Use the RestoreLayoutFromXML method to load the TreeList control’s layout from an XML file. Control settings must have previously been written to this file via the TreeList.SaveLayoutToXml 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 the layout of the Tree List control to an XML file and then restores it. The TreeList.SaveLayoutToXml and TreeList.RestoreLayoutFromXml methods are used for this purpose.

C#
VB.NET

csharp

string fileName = "c:\\TreeListLayout.xml";
treeList1.SaveLayoutToXml(fileName);
treeList2.DataSource = treeList1.DataSource;
treeList2.RestoreLayoutFromXml(fileName);

Dim FileName As String = "c:\TreeListLayout.xml"
TreeList1.SaveLayoutToXml(FileName)
TreeList2.DataSource = TreeList1.DataSource
TreeList2.RestoreLayoutFromXml(FileName)
