Columns are gone if reordering upon reload.

Hi,

I've been experimenting a little with the PersistenceFramework over the course of the day and I've found some, according to me,
mystic behaviour.

When the window containing my RadGridView closes I run this code:

var manager = new PersistenceManager();

var stream = manager.Save(dgOrderOverview);

using (var fileStream = File.Create(System.AppDomain.CurrentDomain.BaseDirectory + "\\objstore.hf"))

{

stream.CopyTo(fileStream);

}

and when I open it up again the following code is run:

//Check if any persistence file exists, and if so, load the view

if (File.Exists(System.AppDomain.CurrentDomain.BaseDirectory + "\\objstore.hf"))

{

var manager = new PersistenceManager();

try

{

var fileStream = File.OpenRead(System.AppDomain.CurrentDomain.BaseDirectory + "\\objstore.hf");

manager.Load(dgOrderOverview, fileStream);

fileStream.Close();

}

catch (Exception ex)

{

System.Diagnostics.Debug.WriteLine(ex.Message, "MYAPPNAME");

}

//Load Context Menu

RadContextMenu ctxMenu = new RadContextMenu();

RadMenuItem item = new RadMenuItem();

foreach (Telerik.Windows.Controls.GridViewColumn column in dgOrderOverview.Columns)

{

RadMenuItem sitem = new RadMenuItem() { Header = column.Header, IsCheckable = true, IsChecked = true };

sitem.SetBinding(RadMenuItem.IsCheckedProperty, new Binding("IsVisible") { Mode = BindingMode.TwoWay, Source = column });

ctxMenu.Items.Add(sitem);

}

RadContextMenu.SetContextMenu(dgOrderOverview, ctxMenu);

For the sake of things it should be noted that I have a RadContextMenu loading in order to be able to show/hide columns in the RadGridView.

Now, here's to the tricky bit, I have a RadContextMenu where the user can set the visibility of the columns, and IF the user ONLY uses this, everything is fine and dandy, visibility properties as set as they should upon reload. However IF the user decides to rearrange the columns, the next time he/she opens up the window, ALL columns are gone, there's NOTHING there at all.

So in short:
* Show / Hide columns using the RadContextMenu bound to the RadGridView works fine, persistence is kept and loads nicely.
* Rearrange columns and the persistence is broken and no columns as viewable upon opening the window.

As a little twist, the columns are all visible in the ContextMenu and their visibility are set as they should, but the GridView doesn't display them.

A little help, please?

P.S
I run the following version of the Telerik components:

[Solved] Hightlighting items in RadPanelBar by tabbing to item

Hi,

I'm trying to figure out how to have individual RadPanelBarItems have their background colors changed when a user tabs through the RadPanelBar. Currently when a user selects (left mouse click) a specific RadPanelBarItem, the color changes to orange (the default color); I want to be able to do the same if the user tabs to the item as well. The usage of IsTabStop and TabStop does not seem to work; I could perhaps be setting it incorrectly.   The following is a code snippet of xaml implementation:

<telerikNavigation:RadPanelBar IsTabStop="True" Grid.Row="0" Grid.Column="0" Grid.RowSpan="2" VerticalAlignment="Stretch" x:Name="SummaryMenu" HorizontalAlignment="Stretch" Margin="0,-1,0,-1">

                    <telerikNavigation:RadPanelBar.Background>
                        <ImageBrush ImageSource="pack://application:,,,/Resources/Images/Left-Menu-Back.png" />
                    </telerikNavigation:RadPanelBar.Background>

                    <telerikNavigation:RadPanelBarItem IsExpanded="True" IsTabStop="True" BorderThickness="0">
                            <telerikNavigation:RadPanelBarItem.Header>
                                <TextBlock Text="VIEWS" Style="{StaticResource SmallMenuHeaderIconLabel}" />
                            </telerikNavigation:RadPanelBarItem.Header>

                        <telerikNavigation:RadPanelBarItem IsTabStop="True" TabIndex="1" MouseLeftButtonDown="SummaryMenuDockingItemLeftButtonDownClick" MouseLeftButtonUp="SummaryMenuDockingItemLeftButtonUpClick" Keyboard.KeyUp="OnKeyPressEnterViewsMenuItem" Tag="MainViewLogicalConfiguration" IsSelected="True">
                                <telerikNavigation:RadPanelBarItem.Header>
                                    <StackPanel Orientation="Vertical">
                                        <Image Source="/Resources/Images/MenuIcons/MainView.png" ToolTip="Main" Style="{StaticResource SmallMenuIcon}"/>
                                        <TextBlock Text="Main" Style="{StaticResource SmallMenuIconLabel}" />
                                    </StackPanel>
                                </telerikNavigation:RadPanelBarItem.Header>
                            </telerikNavigation:RadPanelBarItem>

                        <telerikNavigation:RadPanelBarItem IsTabStop="True" TabIndex="2" MouseLeftButtonDown="SummaryMenuDockingItemLeftButtonDownClick" MouseLeftButtonUp="SummaryMenuDockingItemLeftButtonUpClick" Keyboard.KeyUp="OnKeyPressEnterViewsMenuItem" Tag="PhysicalLayout" >
                                <telerikNavigation:RadPanelBarItem.Header>
                                    <StackPanel Orientation="Vertical">
                                        <Image Source="/Resources/Images/MenuIcons/Physical-Configuration.png" ToolTip="Physical Configuration" Style="{StaticResource SmallMenuIcon}"/>

How to auto max zoom out of timeline

Hi

I'm dynamically adding data into a timeline, everytime I add a data, I set the PeriodEnd property of the timeline control to the max time in the dataset. I like the TimeLine control to be zoomed out to the maximum when a new data is added, how do I achieve that ? I tried setting VisiblePeroidStart and End to PeroidStart and End but that doesn't work.

Any ideas ?

Thanks, Dave

Maximize specific tile using event from fluid content control small content data template of

Hi Telerik

I have defined a tileview using a data template and a radfluidcontentcontrol. The small content definition includes a button which initiates some data fetches in order to create a view which is then placed in a binding in the largecontent template. I want to be able to bind the maximizing of a particular tile to the IsVisibleChanged event on a textblock in the small content template for that tile. (The text block is made visible once the view to be placed in the large content has been created). The approach I have attempted (see below) works for the first tile I try but fails after that. Can you have a look and tell me where I am going wrong please?

Many thanks in advance

Regards
Ian Carson
