UIXamarinForms. Also, you can mix all the size type properties we saw before. Span or Column. Span, and specify which cell you want to span. For example, if you want to remove the green box and expand your pink box to the next column Column 1the code would look like:. Sigue asi, Saludos desde Ecuador, nos conocimos en la ultima conferencia de Xamarin en Orlando. Great stuff Charlin! The Xamarin folks should hire you to write documentation. The way you present information is top notch.

Why use Grids Performance Improvement : Having a screen with a lot of layouts can make the rendering slower, so this is why sometimes you can see an app running slower.
To improve it a better approach is to use a Grid because you will only have one layout with multiple children. Happy coding! Like this: Like Loading Previous Post Next Post. You may also like July 13, October 6, January 8, Good job compiling all this important information together! Its is really helpful information. Keep up the good work. I really liked it.
Thank you soo much. Thank you for clarifying the grid best possible to us. I really appreciate it. I was gathering Xamirin information since last week and Glad to find your blog. Thanks a lot.Download the sample. Grid supports arranging views into rows and columns.
Rows and columns can be set to have proportional sizes or absolute sizes. The Grid layout should not be confused with traditional tables and is not intended to present tabular data.
Grid does not have the concept of row, column or cell formatting. Unlike traditional tables, Grid does not infer the number and sizes of rows and columns from the content.
These hold definitions of how many rows and columns will be laid out. Views are added to Grid with specified row and column indices, which identify which row and column a view should be placed in.
The options for height and width are as follows:. Forms, which ensures that the column will fill the available space. Consider an app that needs three rows and two columns. The bottom row needs to be exactly px tall and the top row needs to be twice as tall as the middle row. The left column needs to be wide enough to fit the content and the right column needs to fill the remaining space. To place views in a Grid you'll need to add them as children to the grid, then specify which row and column they belong in.
Row and Grid. Column on each individual view to specify placement. Note that Grid. Column specify location based on the zero-based lists of rows and columns.
This means that in a 4x4 grid, the top left cell is 0,0 and the bottom right cell is 3,3. The above code creates grid with four labels, two columns, and two rows. Note that each label will have the same size and that the rows will expand to use all available space.GridLayout works with a flat-view hierarchy, where child views set their locations in the grid by specifying the rows and columns they should be in.
This way, the GridLayout is able to position views in the grid without requiring that any intermediate views provide a table structure, such as seen in the table rows used in the TableLayout. By maintaining a flat hierarchy, GridLayout is able to more swiftly layout its child views. The layout will adjust the row and column sizes so that the cells can fit their content, as illustrated by the following diagram:.
When these are not specified, the GridLayout assigns each child view in order, based upon the orientation.
Now, the GridLayout will position the cells from top to bottom in each column, instead of left to right, as shown below:. For example, the following XML will result in the layout shown in the first screenshot shown aboveregardless of the orientation. We have a couple of options that will provide spacing between the child views of the GridLayout.
Additionally, in Android 4, a new general-purpose spacing view called Space is now available. To use it, simply add it as a child view. For example, the XML below adds an additional row to the GridLayout by setting its rowcount to 3, and adds a Space view that provides spacing between the TextViews. The GridLayout also supports cells that span multiple columns and rows.
For example, say we add another row containing a button to the GridLayout as shown below:. This will result in the first column of the GridLayout being stretched to accommodate the size of the button, as we see here:. To keep the first column from stretching, we can set the button to span two columns by setting its columnspan like this:.
Doing this results in a layout for the TextViews that is similar to the layout we had earlier, with the button added to the bottom of the GridLayout as shown below:.

I don't find the properties for rowCouunt, columnCount, orientation, etc in the Grid constructor. I found the sample at link. But I am unable to stretch the grid to fit the width. Apart from that, when I try to populate the grid with many ListViews instead of labels, I see only one ListView per row which stretches across the screen.
Was curious if the grid can be stretched across the screen and the ListView can be contained inside each grid cell? So the simplest way to create a 2x2 grid with 4 labels is :. Is it possible to have for example a 3x3 grid, with a image in each cell, to tell the grid to scale the images that all of them get shown on screen?

Forms Layouts are used to compose user-interface controls into visual structures. Forms are specialized subtypes of views that act as containers for views and other layouts.
The Layout class itself derives from View. A Layout derivative typically contains logic to set the position and size of child elements in Xamarin. Forms applications. You may also leave feedback directly on GitHub. Skip to main content.
Exit focus mode. ContentView ContentView contains a single child that is set with the Content property. The Content property can be set to any View derivative, including other Layout derivatives.
ContentView is mostly used as a structural element and serves as a base class to Frame. Set the Content property to a view or layout too large to fit on the screen. The content of a ScrollView is very often a StackLayout. Set the Orientation property to indicate if scrolling should be vertical, horizontal, or both. StackLayout StackLayout positions child elements in a stack either horizontally or vertically based on the Orientation property.
The Spacing property governs the spacing between the children, and has a default value of 6. A child's position is indicated using the attached properties LayoutBounds and LayoutFlags. An AbsoluteLayout is useful for animating the positions of views. A child's position is indicated using the attached properties that are set to objects of type Constraint and BoundsConstraint. FlexLayout defines six bindable properties and five attached bindable properties that allow children to be stacked or wrapped with many alignment and orientation options.

ContentView contains a single child that is set with the Content property. The Frame class derives from ContentView and displays a border, or frame, around its child. ScrollView is capable of scrolling its contents.

Grid has an image too I tried to work it out, but my trial and error hasn't been very successful, just very time-consuming. But using that as a reference and trying to add other rows and columns it doesn't work. It would be great if their samples included some comments, but as they don't could someone tell me how the GridLayout references work?
Here Understanding Grid Layout. I actually find the answer by Miha Markic a little misleading, not because of the answer he gave is incorrect but because what Xamarin does with those arguments isn't clear from the name.
I originally found the answer on the xamarin forum. I think you'll find the grid much easier to understand if you create it in XAML. In that case, you have rows and columns, and the setup is pretty straight forward. This defines a grid with two rows. It also has two equal columns. Learn more. Forms GridLayout Ask Question.

CollectionView defines the following properties that control layout:. These properties are backed by BindableProperty objects, which means that the properties can be targets of data bindings. By default, a CollectionView will display its items in a vertical list.
However, any of the following layouts can be used:. These layouts can be specified by setting the ItemsLayout property to class that derives from the ItemsLayout class. This class defines the following properties:. For more information about snap points, see Snap points in the Xamarin.
Forms CollectionView Scrolling guide. The ItemsLayoutOrientation enumeration defines the following members:. The LinearItemsLayout class inherits from the ItemsLayout class, and defines an ItemSpacing property, of type doublethat represents the empty space around each item.
The default value of this property is 0, and its value must always be greater than or equal to 0. These members can be used to create vertical or horizontal lists, respectively. Alternatively, a LinearItemsLayout object can be created, specifying an ItemsLayoutOrientation enumeration member as an argument. The GridItemsLayout class inherits from the ItemsLayout class, and defines the following properties:.
CollectionView uses the native layout engines to perform layout. By default, CollectionView will display its items in a vertical list layout. Therefore, it's not necessary to set the ItemsLayout property to use this layout:.
Xamarin.Forms CollectionView Layout
However, for completeness, a CollectionView can be set to display its items in a vertical list by setting its ItemsLayout property to VerticalList :. Alternatively, this can also be accomplished by setting the ItemsLayout property to a LinearItemsLayout object, specifying the Vertical ItemsLayoutOrientation enumeration member as the Orientation property value:. CollectionView can display its items in a horizontal list by setting its ItemsLayout property to HorizontalList :.
Alternatively, this layout can also be accomplished by setting the ItemsLayout property to a LinearItemsLayout object, specifying the Horizontal ItemsLayoutOrientation enumeration member as the Orientation property value:. CollectionView can display its items in a vertical grid by setting its ItemsLayout property to a GridItemsLayout object whose Orientation property is set to Vertical :. By default, a vertical GridItemsLayout will display items in a single column. However, this example sets the GridItemsLayout.
Span property to 2. This results in a two-column grid, which grows vertically as new items are added:. CollectionView can display its items in a horizontal grid by setting its ItemsLayout property to a GridItemsLayout object whose Orientation property is set to Horizontal :. By default, a horizontal GridItemsLayout will display items in a single row. Span property to 4. This results in a four-row grid, which grows horizontally as new items are added:.
CollectionView can present a header and footer that scroll with the items in the list. The header and footer can be strings, views, or DataTemplate objects. CollectionView defines the following properties for specifying the header and footer:.
