RussianQuestion
I 'm using Microsoft.Windows.Controls.Ribbon, and i would like save and load QuickAccessToolBar.
How I Can find QuickAccessToolBar items, in ribbon control?
This is my idea to save ribbon QuickAccessToolBar
- OnClosing application : Get QuickAccessToolBar items, and locaize on Ribbon items. And then serialize
- OnLoad : Read serilize object, and add insert items QuickAccessToolBar
Solution
Finally i did it!
I'm based on WPF Ribbon Sample to save/load. It used datacontext to localize control on RibbonControl, and i didn't like, so i isued QuickAccessToolBarId to localize the control.
This is the solution: - OnClosing Application: I save QuickAccessToolBar, search items on ribbon control by QuickAccessToolBar, and save path. Note: When item is in application menufirst path is -1.A - OnLoadApplication:
Load items , and seerch on ribbon control by path.
And this is the code:
RibbonHelper:
class RibbonHelper
{
Ribbon ribbon;
public RibbonHelper(Ribbon ribbon)
{
this.ribbon = ribbon;
}
string _qatFileName = "qat.xml";
internal void Save()
{
try
{
SaveQatItems();
}
catch { }
}
internal void Load()
{
try
{
LoadQatItems();
}
catch
{
}
}

Classes to serialize:
public class QatItem {
public QatItem()
{
}
public QatItem(int qatbIdHashCode)
{
QuickAccessToolBarIdHashCode = qatbIdHashCode;
}
public Int32Collection ControlIndices

get
{

[DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
public int QuickAccessToolBarIdHashCode { get; set; }
//Is only for load
[DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
public Control Owner { get; set; }
}
public class QatItemCollection : List<QatItem>

And this is the code to save/load from window
RibbonHelper helper;
protected override void OnClosing(CancelEventArgs e)
{
helper.Save();
base.OnClosing(e);
}
private void RibbonWindow_Loaded(object sender, RoutedEventArgs e)
{

helper.Load();
