Hopefully this is a WPF issue and not a esri issue. I have an ESRI map control, and I am placing a control on top of the map. When I do this, the map no longer receives input(I can't move around or click anything). If I modify the z-index of the top control to place it behind the map, the map works fine again.
<Grid Name="MapGrid" DockPanel.Dock="Top" >
<Grid Name="MapGrid" DockPanel.Dock="Top" >
<esri:MapView x:Name="MainMapView" Panel.ZIndex="0" KeyDown="MyMapView_KeyDown" MapViewTapped="MyMapView_MapViewTapped" Map="{Binding Source={StaticResource MapResource}}" WrapAround="True" Grid.Row="0" Grid.Column="0" Initialized="MyMapView_Initialized" >
</esri:MapView>
<Expander Header="Properties" ExpandDirection="Right" Panel.ZIndex="-1">
<ItemsControl Background="Transparent" Height="700" Width="500" HorizontalAlignment="Left" VerticalAlignment="Top" Name="FeaturePropertyRegion" cal:RegionManager.RegionName="FeaturePropertyRegion" />
</Expander>
</Grid>
This code works, but if I raise the ZIndex of the Expander pannel, the map no longer receives input. I am assuming the issue has to do with the visual tree of WPF, and how input cascades down. Any ideas on what the issue could be? Thanks.
EDIT
The issue seems to be with the expander, as the map works if I remove the expander and just have the ItemsControl.
Try :
<Expander IsHitTestVisible="False">
<ItemsControl />
</Expander>
It doesn't seem to be a problem with extender, which would be very wired if it did
I tried this :
<Grid>
<Button />
<Expander HorizontalAlignment="Left" ExpandDirection="Right" VerticalAlignment="Top">
<Rectangle Fill="Red" Stretch="Fill" Width="525" Height="350"/>
</Expander>
</Grid>

I want to instantiate two Controls (an Expander and a Button) from two ControlTemplates. They are docked in a Dockpanel (right and left). The Expander is visible and it works fine, but the Button isn't visible.
The ControlTemplate of the Button in App.xaml:
...
<ControlTemplate x:Key="OpenFileButton" TargetType="{x:Type Button}">
<Image Name="OpenFileButton" Source="F:\AudioNodeGUI_XAML\images\filebutton.jpg">
</Image>
</ControlTemplate>
...
And the instantiation in a usercontrol:
<Grid>
<Image Source="F:\AudioNodeGUI_XAML\images\FileInputNode.jpg"/>
<DockPanel Name="dock" Width="151" Height="20" Margin="27,53,122,139">
<Expander Name="expander" Template="{StaticResource FileExpander}" Height="20" Width="41" PreviewMouseLeftButtonUp="expand" DockPanel.Dock="Left">
<ListView Name="usedFiles" Background="Black" BorderBrush="Transparent" BorderThickness="0" Width="140" Height="120" Opacity="0.5">
</ListView>
</Expander>
<Button Name="OpenFileButton" Template="{StaticResource OpenFileButton}" DockPanel.Dock="Right" />
</DockPanel>
</Grid>
But the Button isn't visible, neither in the Designer (just the outline) nor in execution. What am I doing wrong?
I suspect that your issue is just incorrect path to the image file. Unfortunately you won't have any tip about this kind of error neither in designer nor in output window. However if you have ReSharper it should highlight the path to the file if it doesn't exist
I've seen quite a few people asking this question and i feel like my question is slightly different. I have a listbox that holds a series of identical custom made user controls. These controls are added to the listbox at runtime. Now i currently have my listbox items resizing themselves properly upon first creation and insertion into the control.
Here is the strange part. If I resize the listbox the controls that have been visible previously are not resized to the new listbox width. In other words if i add 12 controls and the box only shows 4 (the rest are hidden by a scrollbar) then if i resize the box the first 4 controls will still be the original width and if i scroll then the other 8 will be the correct size. Also if i manipulate the list items in any way they resize themselves to the proper width automatically. SEE EDIT2
I've tried attaching to the sizeChanged event and issuing the following on both the listbox and the items but it has had no effect. I think i need to find some way of resetting the layout information for the listbox items but i can't find the command.
item.InvalidateArrange();
item.InvalidateMeasure();
Layers.UpdateLayout();
item.UpdateLayout();
I think this has something to do with the items i'm adding because even if i detach the items from the lisbox and then attach them they remain the wrong width.
Here is my listbox code:
<ListBox x:Name="Layers" VerticalContentAlignment="Top" Margin="0,17,0,0" BorderThickness="0,1,0,0" HorizontalContentAlignment="Stretch" SizeChanged="Layers_SizeChanged">
<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch"/>
</Style>
</ListBox.ItemContainerStyle>
</ListBox>
Here is the code for my items
<UserControl x:Class="ListOverlayItem"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

Again it seems like my UserControl is correctly able to scale itself its just not getting the command to do so when the parent container is resized.
EDIT: Whoops, removed the WPF tag because it was incorrectly added. I think i've got it down to slider being the culprit. If i set the slider to a fixed size instead of 'stretch' then the item correctly scales just fine. So the question now is how do i force the slider to resize itself.
EDIT2: I know what is causing the issue but i don't know how to solve it. What is happening is the slider that i have in my user control will NOT resize along with the rest of the control unless i change the value of the slider during the resize. The instant i change its value even a fraction it resizes itself automatically. How can i force it to resize?
I determined that the slider was causing the issue and i tried many ways to force the slider to re-draw when it needed to but i was unsuccessful. My final solution was to remove the slider entirely. Works fine now.
I have a WPF issue that I don't understand - can anyone help?
The WPF below is used as the ContentTemplate for a standard TabControl and resides within a ResourceDictionary. MyElementItemsControl is a simple derivative of ItemsControl and MyDesignCanvas is a simple derivative of Canvas.
<DataTemplate x:Key="TabContent" x:Shared="False">
<Grid>
<Grid Grid.RowSpan="2">
<ScrollViewer x:Name="contentScrollViewer" VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Auto" >

<View:MyElementItemsControl BorderBrush="Transparent" x:Name="schedulePanel" ItemsSource="{Binding Path=Elements}" Background="White">
<View:MyElementItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<View:MyDesignCanvas Height="1000" Width="1000" HorizontalAlignment="Left" VerticalAlignment="Top"
SelectedItem="{Binding SelectedItem, Mode=TwoWay}"
Background="Transparent">
</View:MyDesignCanvas>
</ItemsPanelTemplate>

When I run the code I get two issues I don't understand:
I seem to only get a single ScrollViewer when I would expect a ScrollViewer per item. So if I add two tab items and make the canvas different sizes, the scroll bars are adjusted to the size of the biggest canvas only. I expected that the Shared=False attribute would create new instances of the template for each tab.
Maybe related to item 1 - if I stick a breakpoint on the constructor of MyDesignCanvas it gets hit when the first tab is added but not when other tabs are added. Only when I start closing tabs does the breakpoint get hit again - I would expect a hit on each tab addition.
I guess I don't really understand data templating enough, so can anyone explain what might be going on or point me at some resources that may help me diagnose this?
Thanks
I've realised what the issue is - the WPF TabControl does internal virtualization of tab content, so has been re-using the tab contents and just changing the data context despite me using Shared=False. See this SO question and this one too for more details.
I am developing an application where i want to browse images like native WindowsPhone form.
I have used Pivot control. Everything works, but there is one unwanted thing. The image does not fill all display area. There is a gap on the top of page. I have set margin and padding everywhere where it is possible. And the result is still the same. :(
Here is my XAML code:
<!--LayoutRoot is the root grid where all page content is placed-->
<Grid
x:Name="LayoutRoot"
Background="Transparent"
Margin="0">
<toolkit:PerformanceProgressBar
VerticalAlignment="Top"
HorizontalAlignment="Left"
IsIndeterminate="{Binding IsBusy}"
Visibility="{Binding IsBusy, Converter={StaticResource BoolToVisibilityConverter}}"
/>
<controls:Pivot
x:Name="PhotoPivot"
ScrollViewer.HorizontalScrollBarVisibility="Auto"
IsHitTestVisible="True"
ItemsSource="{Binding Photos}"
Margin="0"
Padding="0"
>
<controls:Pivot.HeaderTemplate>
<DataTemplate/>
</controls:Pivot.HeaderTemplate>
<controls:Pivot.ItemTemplate>
<DataTemplate >
<controls:PivotItem
x:Name="PhotoPivotItem"
Margin="0"
>
<Image
x:Name="PhotoPicture"
Source="{Binding}"
Stretch="Uniform"
HorizontalAlignment="Stretch"
VerticalAlignment="Stretch"
Margin="0"
/>
</controls:PivotItem>
</DataTemplate>
</controls:Pivot.ItemTemplate>
</controls:Pivot>
</Grid>
Are you talking about the system tray?
To remove the system tray use the following code:
shell:SystemTray.IsVisible="False"
Update:
I'm not real sure why that extra space is there.
I created a simplified version of your example and the only thing I could think of is to use negative margins. There is probably a better solution that I am just overlooking, but for now you can just use the following:
<controls:PivotItem x:Name="PhotoPivotItem" Margin="0,-10,0,0">
Although, from your posted image, it looks as if you have a bigger gap than I did, so you might need to decrease the margin.
I would like to build a WPF window application using the following layout structure. Consider title and button on left hand frame/window like "Master Pages" in ASP.Net. On the right hand frame it should be a WPF navigation window.
When I include Navigation Window as an UI element at the last stack panel, it throws me and error. How should I design the entire layout according to the image screenshot below? Thanks
<Window x:Class="MainWindow"
xmlns:local="clr-namespace:ClientSocket"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title=" Desktop" Height="841" Width="1271" WindowStartupLocation="CenterScreen" WindowState="Maximized">
<DockPanel>
<StackPanel DockPanel.Dock ="Top" Orientation="Horizontal" Background="Red">
<TextBlock Background="red" FontSize ="36" Width="482" >
Main Title
</TextBlock>
</StackPanel>
<StackPanel Background="LightGray" DockPanel.Dock ="Left" Width="145">
<Button Content="Button1" Name="btnAndroid" Width="119" Margin="3" BorderBrush="{StaticResource {x:Static SystemColors.InfoBrushKey}}" />
<Button Content="Button2" Name="btnDownloads" Width="119" Margin="3" BorderBrush="{StaticResource {x:Static SystemColors.InfoBrushKey}}" />
<Button Content="AddNewDownloads" Height="37" Name="Button1" Width="133" />
</StackPanel>
<StackPanel>
<NavigationWindow Height="auto" Width="auto" Name="nwMain" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" BorderBrush="Blue" BorderThickness="1" />
</StackPanel>
</DockPanel>
</Window>
You cannot add a window as the child of anything, there is a nestable navigation control which you can use here instead, it is called Frame.
Layout-wise i would recommend a Grid with two rows, contains another Grid (in Grid.Row="1") with two columns.
DockPanels are sad controls that probably should not be used, unless someone points a gun at you and tells you to.
