PivotGridControl.RestoreLayoutFromRegistry(String, OptionsLayoutBase) Method
Restores the Pivot Grid Control’s layout stored at the specified system registry path, using the specified settings.
NuGet Package: DevExpress.Win.PivotGrid
public void RestoreLayoutFromRegistry( string path, OptionsLayoutBase options )
Public Sub RestoreLayoutFromRegistry( path As String, options As OptionsLayoutBase )
A string value specifying the system registry path. If the specified path doesn’t exist, calling this method does nothing.
A OptionsLayoutBase descendant which specifies which options should be restored.
Use the RestoreLayoutFromRegistry method to restore the layout of a Pivot Grid Control which has been stored to the system registry using the PivotGridControl.SaveLayoutToRegistry method.
The options parameter determines which options should be restored from the registry. For a Pivot Grid Control you can create a OptionsLayoutGrid object, customize it as required and then pass it as the options parameter. Only the options that are enabled in this object will be restored.
To restore all the options you can pass null or the static OptionsLayoutBase.FullLayout property as the options parameter.
The RestoreLayoutFromRegistry method overload without the options parameter restores only the options which are specified by the PivotGridControl.OptionsLayout property.
Each layout has a version attribute. When saving a layout its version is determined by the OptionsLayoutBase.LayoutVersion property. This property can be accessed via the PivotGridControl.OptionsLayout property.
Layout versions help when updating previously saved layouts. When a layout is being restored its version is compared with the version specified by the OptionsLayoutBase.LayoutVersion property. If the versions don’t match the PivotGridControl.LayoutUpgrade event is fired and this can be handled to customize the Pivot Grid Control immediately after the old layout has been loaded.
For the path parameter you can define whole and partial registry keys. For example, if you define “Software\Company", the full path will be as follows: “HKEY_CURRENT_USER\Software\Company". To store a layout in a different root key define the entire path in the following form “HKEY_LOCAL_MACHINE\Software\Company".
When restoring a layout during a form load (for instance, in your Form.Load event handler), you may need to call the PivotGridControl.ForceInitialize method prior to the layout restoration. See this method to learn more.
