I can't seem to figure out how I can stretch the items of my horizontal listview.
I have a list of items, and each one of those items contain a list of other items. Which means I have a list nested in another list. Since I want to display the items of the nested list horizontally, I have used StackPanel.
<ListView.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel HorizontalAlignment="Stretch" Orientation="Horizontal" />
</ItemsPanelTemplate>
</ListView.ItemsPanel>
However it seems like it is not possible to stretch and make all the rectangles have the same width, while filling out the page, with StackPanel. Even with setting the HorizontalContentAlignment and HorizontalAlignment of the ListView to "Stretch". Is there a way to solve this problem? It seems like I should use Grid somehow, but since the list length of the nested list varies, I'm not sure.
Below is how it looks like, I just want the width of the rectangle to stretch and have the same width, filling out the empty space. The width of the rectangles should adjust if you make the app width bigger or smaller.
This is how I want it to look

I am trying to get a RichEditBox to take over the entire width of the app window and to be responsive to window resizing, so far the code I have is the following:
<RichEditBox HorizontalAlignment="Stretch"
TextWrapping="WrapWholeWords"
Height="250"
Name="Intro"/>
What I am getting from the code above is this:
Any ideas on how can I get this to work? Why is it that I tell the text to wrap and it doesn't follow?
UPDATE
I also tried this:
<RichEditBox HorizontalAlignment="Stretch"
Height="250"
Name="Intro"/>
But the result is:
The problem that I am having is that it seems that HorizontalAlignment="Stretch" does not really do anything. The only way I am able to set a decent width is by hard-coding it, for example: Width="600". But if I do this my UI will not respond correctly to resizing. I also tried HorizontalContentAlingment="Stretch" but the result is exactly the same.
How can I get my RichEditBox take up all the available Width and Wrap at the same time?
If you look at the documentation of RichEditBox.TextWrapping, you'll notice that WrapWholeWords is invalid. You have to use
<RichEditBox TextWrapping="Wrap"/>
-or-
<RichEditBox TextWrapping="NoWrap"/>
Since Wrap is the default value, you can drop the property.
<RichEditBox HorizontalAlignment="Stretch"
Height="250"
Name="Intro"/>
Edit: in reply to the updated question:
A control only takes the width of it's parent control. Some container controls (e.g. Grid) automatically take the full width available, while others (e.g. StackPanel) only take the required size of it's children. Using HorizontalAlignment="Stretch" in combination with a StackPanel as a parent control, will only use the MinWidth property instead of the full available width on your screen. Sometimes you can't directly see this issue, e.g. when your control is inside an itemtemplate of a ListView. Use the Live Visual Tree in Visual Studio to find the parent containers and locate the issue.
So in short: make sure your RichEditBox is inside a Grid (or similar control) instead of a StackPanel.
I ran into a little bug while creating a scrollable stackpannel. I used the scrollviewer. I have placed the Stackpannel inside the Scrollviewer but I can't scroll using a emulator.. I don't have a windows phone so I cant check it out on an actual phone. Here is my code:
<ScrollViewer Height="979" Margin="0,100,0,-439" VerticalAlignment="Stretch">
<StackPanel Height="979" VerticalAlignment="Stretch" Width="268">
// things inside the stackpannel
</StackPanel>
</ScrollViewer>
Am I doing something wrong or does the scrollviewer not work in an emulator?
The height of the ScrollViewer is the same as the height of the StackPanel so there is nothing to scroll (it just falls off the end of the screen). Try using VerticalAlignment="Stretch" instead of setting Height on the ScrollViewer which should help (if not, you have some other problem in your layout ;-) but using a fixed, smaller Height for the ScrollViewer will solve this immediate problem).
I have this grid-view loading dynamic content correctly. However I can't quite figure out how to make it fill how I want. I want the content to start in the upper left corner and then create instance going downward until no more can fit (This should be 4) then start back at the top to the right of the original item.
The maxRowsOrCols property give me the behavior I desire, but I will definitely be exceeding 4 columns.
Please teach me.
You can use an ItemsPanel with the WrapGrid. The Orientation property is Horizontal or Vertical first. This should allow you to set your layout as required, depending on screen size and ItemTemplate.
<GridView.ItemsPanel>
<ItemsPanelTemplate>
<WrapGrid MaximiumRowsOrColumns="4" Orientation="Vertical"/>
</ItemsPanelTemplate>
</GridView.ItemsPanel>
I have a custom WPF control to display a list of items using an ItemsControl. The ItemsPresenter is defined in the template to display the list and it is embedded inside a ScrollViewer for scrolling purposes:
<ControlTemplate TargetType="ItemsControl">
<Grid x:Name="LayoutRoot">
<ScrollViewer Margin="3">
<ItemsPresenter/>
</ScrollViewer>
</Grid>
</ControlTemplate>
My application creates two instances of the custom control to show the list side by side.
What I want is when user selects an item on the first one, the second control automatically scrolls so that the same item is displayed in the same position relative to the top. To accomplish this I need to know
How to get the position (in pixels) of the selected item in the first control?
How to scroll to the same position in the second control?
Are there any other ways to do this?
I have a project that in which I have a RadGridView inside of a Scrollviewer. I've been trying to bind the width of the RadGridView to the width of the ScrollViewer. The ScrollViewer's width is set to Auto so that it will expand to fit the size of it's containing object, but when I bind the width of the RadGridView to the ScrollViewer it only expands to fit the information inside of the RadGridView instead of filling the remaining space of the ScrollViewer. What I would like is for the RadGridView to expand to auto fit the ScrollViewer, which also expands automatically to fit the parent object. However I haven't been able to find a workable solution for this problem, any ideas?
You don't really need to bind the width of the RadGridView to the ScrollViewer, just don't set the size of the RadGridView, like the following,
<ScrollViewer Margin="60" ScrollViewer.HorizontalScrollBarVisibility="Auto">
<telerik:RadGridView ItemsSource="{Binding Collection}"/>
</ScrollViewer>
Please let me know if I misunderstood your question.
