When I place a Datagrid in a WPF Grid Layout container, the datagrid lengthens the Grid Layout.
I want it to occupy only the space available on screen.
Make sure your Grid.ColumnDefinition or Grid.RowDefinition's Width or Height is not set to Auto. If you set it to a fixed size or a star size then the row/column should not resize.
If you're still having problems a code sample would be useful.
You should place your Datagrid into a ScrollViewer, and the ScrollViewer into your Grid cell.
the grid is placed inside a tabitem.
I tried the scrollviewer. but the only thing that happens:
the scrollviewer gets as large as the too long datagrid.
as the tabitem can vary in height, I would rather not like to specify a fixed height for the grid.

in WPF is there a way to setup a TextBlock so its MinHeiht and MinWidth are automatically set so its content is completely visible or should I code this by myself?
Thanks.
EDIT: The TextBlock lives inside a grid row, I would like to setup the Min sizes of the row to allow the TextBlock to show its entire content.
If you set the columndefinition width for the textblock's column to 'Auto', it will grow automatically to accommodate the growing textblock.
I want to set the MinWidth of a Grid ColumnDefinitions to the ActualWidth of a DataGrid inside it.
The main problem is the DataGrid has a (built-in) vertical scroller since its contents are many. So, the actual width is the size of its columns and some more, but not including the scroller.
What happens is that when I set the MinWidth, I get the rightmost column hidden behind the scroller.
I appreciate solving this both in the code and the XAML (just in order to learn).
Try putting the DataGrid into a Canvas and bind to the ActualWidth property of that instead.
I am using an ItemsControl to place n number of Expanders. My ItemsControl will be placed in a Grid with height 600 (for example). I want to make sure my ItemsControl will always occupy the entire available Height, to do so it can expand some of the Expanders.
What will be the best approach to do so?
One way would be to bind the Height and Width properties of your control to the parent's ActualWidth and ActualHeight properties
I would like to set some limits/boundaries on the amount of pixels we can stretch a gridsplitter control which is inside a grid.How is this possible?
Basically one should not be allowed to pull the gridsplitter to large limits(it should be restricted to smaller grid boundaries)
You could use MinWidth and MaxWidth on the ColumnDefinition class.
Why doesn't a textbox stretch to fill space in a stackpanel? Is this by design? In a grid, the textbox stretches as expected.
Yes, it's by design. The StackPanel will allocate the space the TextBox asks for. If you haven't set a width on the TextBox, it will require only enough width to fit its text.
Kent's answer seems right.
To still force override the StackPanel behavior, I think you'd need to dynamically compute-set the Width property of the contained elements OR some funky override of MeasureOverride. I'd rather use another layout manager/panel. Some things I noted..
The default value for HorizontalAlignment and VerticalAlignment properties of child elements is Stretch (if you don't specify one explicitly).
The StackPanel will stretch elements based on its Orientation property value. So
Orientation=Horizontal means all elements will be vertically stretched to max. Elements flow horizontally.
Orientation=Vertical means all elements will be horiz stretched to max. Elements flow vertically.
Unless explicitly specified, Width and Height of child elements are NaN. If you specify an explicit value, StackPanel will honor them over the Horiz and Vert Alignment settings.
The StackPanel itself has HorizontalAlignment and VerticalAlignment that adds a further layout twist. You can experiment with this example.
StackPanel
The default value is stretch for both
HorizontalAlignment and
VerticalAlignment of content that is
contained in a StackPanel.
HorizontalAlignment
When Height and Width properties are
explicitly set on an element, these
measurements take higher precedent
during layout and will cancel the
typical effects of setting
HorizontalAlignment to Stretch.
I needed items to be sized evenly, but stacked vertically.
I used a UniformGrid, and set the Columns property to 1. (tested with a TextBox, and it stretches like you want)
