I have an image binding on gridview with XAML below:
<Border x:Name="coverBox" Grid.Row="0" Margin="5,10,0,0" Width="230" Height="170" VerticalAlignment="Top" HorizontalAlignment="Left" BorderBrush="Gray" BorderThickness="1" Background="{x:Null}">
<Image x:Name="cover" Source="{Binding Thumbnail}" HorizontalAlignment="Center" Stretch="Uniform" AutomationProperties.Name="{Binding Title}" Width="230" Height="170"/>
</Border>
Code:
string urlPath1 = "http://..../API/sekolah";
var httpClient1 = new HttpClient(new HttpClientHandler());
var values1 = new List<KeyValuePair<string, string>>
{
new KeyValuePair<string, string>("api_key", "...."),
new KeyValuePair<string, string>("limit", limit++.ToString()),
new KeyValuePair<string, string>("hal", noHal++.ToString())
};
var response1 = await httpClient1.PostAsync(urlPath1, new FormUrlEncodedContent(values1));
response1.EnsureSuccessStatusCode();
if (!response1.IsSuccessStatusCode)
{
busyIndicator.IsActive = false;
RequestException();
}
string jsonText1 = await response1.Content.ReadAsStringAsync();
JsonObject jsonObject1 = JsonObject.Parse(jsonText1);
JsonArray jsonData1 = jsonObject1["data"].GetArray();
foreach (JsonValue groupValue1 in jsonData1)
{
JsonObject groupObject2 = groupValue1.GetObject();
string thumbnail = groupObject2.ContainsKey("thumbnail") && groupObject2["thumbnail"] != null ? groupObject2["thumbnail"].GetString() : string.Empty;
ListingClass file1 = new ListingClass();
file1.Thumbnail = thumbnail;
listingDatasourceDetail.Add(file1);
}
listingGridView.ItemsSource = listingDatasourceDetail;
I want while still loading to take the image data from JSON, then show the paceholder images/SEKOLAH-place-holder-600.png first
How to add placeholder while still loading?
Wrap your cover Image within a Grid, then create another Image to display the placeholder png and place it behind cover.
Try add Loading event to Image :
private void myimage_Loading(FrameworkElement sender, object args)
{
Image myimage = (Image)sender;
myimage.Source = new BitmapImage(new Uri("ms-appx:///images/SEKOLAH-place-holder-600.png"));
}

I have a gridview with the name "majorGridView" inside a gridview with the name "assessmenGridView" whose data is data binding
XAML:
<GridView x:Name="asesmenGridView">
<GridView.ItemTemplate>
<DataTemplate>
<UserControl>
<Grid>
<StackPanel
x:Name="judulStack"
Height="40">
<TextBlock
x:Name="judulT"
Text="{Binding Title}"/>
</StackPanel>
<GridView
x:Name="majorGridView">
<GridView.ItemTemplate>
<DataTemplate>
<UserControl>
<Grid>
<TextBlock
x:Name="kelasT"
Text="{Binding Major}"/>
</Grid>
</UserControl>
</DataTemplate>
</GridView.ItemTemplate>
</GridView>
</Grid>
</UserControl>
</DataTemplate>
</GridView.ItemTemplate>
</GridView>
How to display binding text on "majorGridView" ? Because if I use the code below, I will get an error message: "The name 'majorGridView' does not exist in the current context"
Code:
ObservableCollection<Ujian> ujiandatasource = new ObservableCollection<Ujian>();
ObservableCollection<Ujian> majordatasource = new ObservableCollection<Ujian>();
string urlPath = "https://pto.study.id/api/" + ((App)(App.Current)).AsesmenCode + "-do/s2/choose-exam/" + guru.ID;
var httpClient = new HttpClient(new HttpClientHandler());
httpClient.DefaultRequestHeaders.Add("Authorization",
string.Format("Bearer {0}", tkn));
var response = await httpClient.GetAsync(urlPath);
string jsonText = await response.Content.ReadAsStringAsync();
try
{
JsonArray jsonArray = JsonArray.Parse(jsonText);
foreach (JsonValue groupValue in jsonArray)
{
JsonObject groupObject = groupValue.GetObject();
JsonArray majorArray = groupObject["majors"].GetArray();
foreach(JsonValue majorValue in majorArray)
{
JsonObject majorObject = majorValue.GetObject();
string major = majorObject["major"].GetString();
Ujian ujian1 = new Ujian();
ujian1.Major = major + ", ";
majordatasource.Add(ujian1);
majorGridView.ItemsSource = majordatasource;
}
Ujian ujian = new Ujian();
ujian.Title = title;
ujiandatasource.Add(ujian);
asesmenGridView.ItemsSource = ujiandatasource;
}
Ujian.cs
class Ujian
{
public string Title { get; set; }
public string Major { get; set; }
}
}
The name 'majorGridView' does not exist in the current context"
majorGridView in the parent DataTemplate, so we can't access majorGridView with name directly. For this scenario, we often use nested collection apply the value generally. And here is similar case that you could refer to.
I'm getting data from api via async task:
public async Task<PostModel.Post[]> GetPostsAsync()
{
var client = new HttpClient();
var uri = new Uri("link here");
var response = await client.GetAsync(uri);
if (response.IsSuccessStatusCode)
{
var jsonString = await response.Content.ReadAsStringAsync();
var rootObject = JsonConvert.DeserializeObject<PostModel.Post[]>(jsonString);
return rootObject;
}
else
return null;
}
Also I've created a simple vertical view:
<ContentPage.Content>
<ListView x:Name="MainView">
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<StackLayout Orientation="Vertical" HorizontalOptions="Fill" VerticalOptions="Fill" BackgroundColor="WhiteSmoke">
<Frame OutlineColor="Black">
<Label x:Name="Title" Text="{Binding Name}"/>
<Image x:Name="Image" Source="{Binding path}" />
</Frame>
</StackLayout>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</ContentPage.Content>
Wrote a custom cell for displaying data:
public CustomCell()
{
//instantiate items in views
var Image = new Image();
var NameLabel = new Label();
var horizontalLayout = new StackLayout() { BackgroundColor = Color.WhiteSmoke };
//set bindings
NameLabel.SetBinding(Label.TextProperty, new Binding("Name"));
Image.SetBinding(Image.SourceProperty, new Binding("path"));
Image.HorizontalOptions = LayoutOptions.Center;
Image.HeightRequest = 600;
Image.WidthRequest = 600;
NameLabel.FontSize = 24;
//add views to the view hierarchy
horizontalLayout.Children.Add(NameLabel);
horizontalLayout.Children.Add(Image);
//add to parent view
View = horizontalLayout;
}
Now I'd like to populate layout from the async task dynamically. For example if task gets 6 items - create 6 cells with data from each of the async task items. Any suggestions how can i do it? I'm completely green in xamarin.forms and just started trying it.
in OnAppearing, just set the source for your ListView
MainView.ItemSource = await GetPostsAsync();
I have a JSON like this:
I want to show the "rating" of data in gridview using the image below:
For example, the rating value is 5, it will be displayed as follows:
and if the rating is 3, it will be displayed as follows:
and if the rating is 0, it will be displayed as follows:
code:
try
{
loading.Visibility = Visibility.Visible;
string urlPath1 = "http://.../results.json?module=listing&page=1&token=3f63-dc43-c8d5-eb45-8cbf-b72d-9d98-800f";
var httpClient1 = new HttpClient(new HttpClientHandler());
var values1 = new List<KeyValuePair<string, string>>
{
};
HttpResponseMessage response1 = await httpClient1.GetAsync(urlPath1);
response1.EnsureSuccessStatusCode();
if (!response1.IsSuccessStatusCode)
{
busyIndicator.IsActive = false;
RequestException();
}
string jsonText1 = await response1.Content.ReadAsStringAsync();
JsonObject jsonObject1 = JsonObject.Parse(jsonText1);
JsonArray jsonData1 = jsonObject1["data"].GetArray();
foreach (JsonValue groupValue1 in jsonData1)
{
JsonObject groupObject2 = groupValue1.GetObject();
string title = groupObject2["title"].GetString();
double rating = groupObject2["rating"].GetNumber();
ListingClass file1 = new ListingClass();
file.Title = title;
file1.Rating = Convert.ToInt32(rating);
listingDatasource.Add(file1);
}
itemGridView.ItemsSource = listingDatasource;
busyIndicator.IsActive = false;
}
catch (HttpRequestException ex)
{
busyIndicator.IsActive = false;
RequestException();
}
How do you show the rating using the picture?
Note:
The maximum value of the rating is 5
It seems you should be able to use the third-party control, such as the UWP-Composition-Rating-Control.
W should be able to set the your images to the FilledImage and EmptyImage property of the Rating control. Then we can bind the number of the Rating in ListingClass class to the Value of the Rating control.
For example:
<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<GridView Name="itemGridView">
<GridView.ItemTemplate>
<DataTemplate>
<StackPanel>
<TextBlock Text="{Binding Title}"></TextBlock>
<controls:Rating x:Name="Devils"
Value="{Binding Rating}"
Maximum="5"
ItemHeight="60"
ItemPadding="24"
StepFrequency="1"
EmptyImage="ms-appx:///Assets/empty.png"
FilledImage="ms-appx:///Assets/filled.png" />
</StackPanel>
</DataTemplate>
</GridView.ItemTemplate>
</GridView>
</Grid>
I'm having a problem with a ListView for Windows Phone:
I'm using a databinding to display all items in a folder, but when I try to iterate through them, I don't get a control, but the class I use to get the items in the LocalFolder of the app (The subjectpicker class)!
SubjectPicker class:

List<Brush> Colors = new List<Brush>();
List<string> Items = new List<string>();
List<List<TestOrTask>> TestsAndTasks = new List<List<TestOrTask>>();
StorageFolder LocalFolder = ApplicationData.Current.LocalFolder;
var files = await LocalFolder.GetFilesAsync();
foreach (var file in files) {
//await file.DeleteAsync();
List<TestOrTask> TAT = new List<TestOrTask>();
Names.Add(file.DisplayName);
bool readItems = false;
var contents = await FileIO.ReadLinesAsync(file);
foreach (var content in contents) {
if (content.Contains("Subject Color")) {
string colorname = content.Replace("Subject Color: ", "");
Colors.Add(ColorConverter.fromString_Brush(colorname));
}
else if (content == "<Items>") readItems = true;
else if (content == "</Items>") readItems = false;
if (readItems == true && content != "") {
// Layout: <Name>: <Score>/<Maximum>|<YYYY>/<MM>/<DD>
string name = content.Split(':')[0];
string Score = content.Split(':')[1].Replace(" ", "");
string Date = content.Split('|')[1];
TestOrTask TOT = new TestOrTask(
name,
double.Parse(Score.Split('/')[0]),
double.Parse(Score.Split('/')[1]),
new DateTime(
Int32.Parse(Date.Split('/')[0]),
Int32.Parse(Date.Split('/')[1]),
Int32.Parse(Date.Split('/')[2])));
TAT.Add(TOT);
}
}
Items.Add("Aantal Testen & Taken: " + TAT.Count.ToString());
TestsAndTasks.Add(TAT);
}
var data = new List<SubjectPicker>();
for (int i = 0; i < Names.Count; i++) {
data.Add(new SubjectPicker(Names[i], Colors[i], Items[i], TestsAndTasks[i]));
}
return data;
}
public SubjectPicker(string name, Brush color, string itemstotal, List<TestOrTask> TestsAndTasks) {
PickerName = name;
PickerColor = color;
ItemTotal = itemstotal;
this.TestsAndTasks = TestsAndTasks;

Thanks in advance!!!
When iterating on databinded control you'll always get its underlying data.
You should Style.Triggers to alter UI based on data (changing background, showing/hiding controls, etc.).
However, there is a way to go with altering UI from C# but that would make XAML and code-behind tightly coupled => that introduces more complexity into your code - simply believe me, it is not what you want/need.
i have a huge problem....
i have a MainWindow.xaml. this xaml is seperated into differnt columns and rows. in. on the left side i have my different buttons. on the right side i have my so called content grid. in this content grid i open my different user controls by pressing a button.
in one of these user controls i request a route from A to B. if the points are excatly identified the route gets displays in the listbox below the input screen.
but if one of the two points isn't exactly identified i open a new window with two comboboxes where you have to specify and select your inputs. after choosing your start and destination points. the window should be closed by pressing the button OK and in the listbox in the user control the route should bey displayed....but it doesn't...
my english isn't that good and i hope you can help me by posting the code..

my aim is if the new window appears, i specifiy my station, the i click on OK, the window closes and in the listbox my result gets displays.
everything works, cause if i say MessageBox.Show(xml.ToString()); in the formatData(XElement xml) Method it displays me the right xml file...but it doesn't appear in the listbox....
Take a look to the Button_Click method of your RoutenplanungSelection window: first you retrive a couple of selected values, then you create a new instance of Routenplanung window.
Of course that new instance is not the same instance of the main window you see on the screen. In your secondary window you should have a reference to the main one.
