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.

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 am creating a UWP application and I want a simple check box, no text, for each entry in my ListView. If I add a checkbox control to my template for the listview, I get a big gap after the checkbox for the Content - event when the content is empty.
If I turn on multiselect in the listview so I get a nice checkbox for each row, I can't seem to figure out how to databind the check box for each row in the listview to the Selected property of my ViewModel.
Below is a picture of what I want the area of the check box to look like. This was generated using the SelectionMode="Multiple" on the listview. Remember - the problem with this approach is I can't seem to find a way to bind the check box to the Selected property of my ViewModel class.
Below is what it looks like if I remove the SeletionMode property and add a check box to my ItemTemplate. As you can see there is a huge gap between the check box and the area where the image will be due to the Checkbox control's minimum width of 120.
Any suggestions would be greatly appreciated.
You could just set the MinWidth on the Checkbox itself
eg
<StackPanel Orientation="Horizontal">
<CheckBox x:Name="MyCheck" IsChecked="True" MinWidth="30"/>
<Rectangle Fill="Red" Width="100" Height="50"/>
</StackPanel>
The alternative is creating a copy of the Checkbox Styles and Template but that seems like overkill here.
How could one accomplish behavior in which a header of a ListView or GridView group doesn't scroll with the content, but stays fixed until the content comes to an end and the following header then comes in focus.
The behavior can be observed in Finance app on Windows 8 Release Preview when you scroll through GridView items.
I am not expecting the whole code, but I'd like to hear some ideas, links, code snippets, samples etc. which would help me get started.
Thanks
You might be able to embed a listview in a datatemplate of the main listview. Then you can embed a gridview and gridviewcolumns in the templated listviews and get your column headers that way.
Wrap the ListView in a ScrollViewer. The ListView's internal SrollViewer won't be used, and you'll have control of the outer ScrollViewer, which will allow you to set its TopHeader.
<ScrollViewer>
<ScrollViewer.TopHeader>
... Your header content here ...
</ScrollViewer.TopHeader>
<ListView HorizontalAlignment="Left" VerticalAlignment="Top">
... Your body content here ...
</ListView>
</ScrollViewer>
The GridView and the ListView in XAML seem to be the same control.
How does a developer choose between the two?
The GridView control typically scrolls horizontally. Also, you will see some native spacing between items that is greater than that in the ListView. This spacing is there because of the intent for how the controls will be used in Windows Store apps. (read on)
Like the ListView it inherits from ItemsControl.
Like the ListView groups using GroupStyle.
Like the ListView it supports the two new Virtualization strategies.
Like the ListView it supports the different Selection modes.
Sample syntax:
<GridView>
<x:String>Item 1</x:String>
<x:String>Item 2</x:String>
</GridView>
The ListView control typically scrolls vertically.
Sample syntax:
<ListView>
<x:String>Item 1</x:String>
<x:String>Item 2</x:String>
</ListView>
THIS IS THE ANSWER
The general differentiation between the two is their occurance in views. A GridView tends to appear in FullView, FillView, and Portait. The ListView, because of its vertical orientation, tends to appear in the SnapView. Either control can appear in either view, but this is the local diversion of the two controls.
MSDN: The ListView and GridView controls are both used to display
collections of data in your app. They have similar functionality, but
display data differently. They are both derived from the ItemsControl
class. When we talk about an ItemsControl, the info applies to both
the ListView and GridView controls.
The ListView displays data stacked vertically. It's often used to show
an ordered list of items, such as a list of emails or search results.
It's also useful in master-detail scenarios, where the list items
contain only a small amount of info and the details of the selected
item are shown separately.
The GridView displays data stacked horizontally. It's often used when
you need to show a rich visualization of each item that takes more
space, such as a photo gallery.*
The only difference the user will notice is the touch selection gesture. For GridView the selection gesture is an Up->Down swipe. For ListView it's a Left->Right swipe. I assume this is so the list can differentiate a selection swipe from a scroll attempt.
In Xaml you'll also notice that the default ItemsPanel is different. ItemsWrapGrid for GridView and ItemsStackPanel for ListView (as of Win8.1 virtualizing panels; in 8.0 it's WrapGrid and StackPanel). This could affect what properties are available to you for customization in your Xaml.
