how to fetch and populate data using ODataV4 in Xamarin.Forms datagrid
2+
3+
## About the sample
4+
This example illustrates how to fetch and popuplate data using ODataV4 in Xmarin.Forms SfDataGrid.
5+
6+
Simple.OData.Client is a cross-platform client library through which you can fetch and update data online. In, the below sample we fetched the data from online and loaded those data to SfDataGrid by using Simple.OData.Client library.
7+
8+
```C#
9+
public class ResultsPage : ContentPage
10+
{
11+
IEnumerable<Package> packages;
12+
SfDataGrid dataGrid;
13+
ActivityIndicator activityIndicator;
14+
public ResultsPage()
15+
{
16+
Title = "Search Results";
17+
18+
NavigationPage.SetHasNavigationBar(this, true);
19+
20+
var stackLayout = new StackLayout() { VerticalOptions = LayoutOptions.FillAndExpand };
21+
22+
if (Device.OS == TargetPlatform.WinPhone)
23+
{
24+
// WinPhone doesn't have the title showing
25+
stackLayout.Children.Add(new Label { Text = Title, Font = Font.SystemFontOfSize(50) });
26+
}
27+
28+
var searchButton = new Button() { Text = "Get Data" };
29+
searchButton.Clicked += async (sender, e) =>

89+
command.Select(x => new { x.Id, x.Title, x.Version, x.LastUpdated, x.DownloadCount, x.VersionDownloadCount, x.PackageSize, x.Authors, x.Dependencies });

Any raw assets you want to be deployed with your application can be placed in
2+
this directory (and child directories) and given a Build Action of "AndroidAsset".
3+
4+
These files will be deployed with you package and will be accessible using Android's
5+
AssetManager, like this:
6+
7+
public class ReadAsset : Activity
8+
{
9+
protected override void OnCreate (Bundle bundle)
10+
{
11+
base.OnCreate (bundle);
12+
13+
InputStream input = Assets.Open ("my_asset.txt");
14+
}
15+
}
16+
17+
Additionally, some Android functions will automatically load asset files:
18+
19+
Typeface tf = Typeface.CreateFromAsset (Context.Assets, "fonts/samplefont.ttf");

Images, layout descriptions, binary blobs and string dictionaries can be included
2+
in your application as resource files. Various Android APIs are designed to
3+
operate on the resource IDs instead of dealing with images, strings or binary blobs
4+
directly.
5+
6+
For example, a sample Android app that contains a user interface layout (main.xml),
7+
an internationalization string table (strings.xml) and some icons (drawable-XXX/icon.png)
8+
would keep its resources in the "Resources" directory of the application:
9+
10+
Resources/
11+
drawable-hdpi/
12+
icon.png
13+
14+
drawable-ldpi/
15+
icon.png
16+
17+
drawable-mdpi/
18+
icon.png
19+
20+
layout/
21+
main.xml
22+
23+
values/
24+
strings.xml
25+
26+
In order to get the build system to recognize Android resources, set the build action to
27+
"AndroidResource". The native Android APIs do not operate directly with filenames, but
28+
instead operate on resource IDs. When you compile an Android application that uses resources,
29+
the build system will package the resources for distribution and generate a class called
30+
"Resource" that contains the tokens for each one of the resources included. For example,
31+
for the above Resources layout, this is what the Resource class would expose:
32+
33+
public class Resource {
34+
public class drawable {
35+
public const int icon = 0x123;
36+
}
37+
38+
public class layout {
39+
public const int main = 0x456;
40+
}
41+
42+
public class strings {
43+
public const int first_string = 0xabc;
44+
public const int second_string = 0xbcd;
45+
}
46+
}
47+
48+
You would then use R.drawable.icon to reference the drawable/icon.png file, or Resource.layout.main
49+
to reference the layout/main.xml file, or Resource.strings.first_string to reference the first
50+
string in the dictionary file values/strings.xml.
