There is a ContestListView with elements:
public MainPage()
{
this.InitializeComponent();
List<int> list = new List<int>();
list.Add(2);
list.Add(3);
list.Add(5);
list.Add(7);
ContestListView.ItemsSource = list;
}
I want to navigate to another Frame when SelectionChange is.
private void ContestSelectionChange(object sender, SelectionChangedEventArgs e)
{
this.Frame.Navigate(typeof(BlankPage1));
}
But I have a problem - sometimes, when I choose element at list, the BlankPage1 starts load, but I got an unhandled exception
{"Unspecified error\r\n\r\nUnspecified error\r\n"}
at this place
#if DEBUG && !DISABLE_XAML_GENERATED_BREAK_ON_UNHANDLED_EXCEPTION
UnhandledException += (sender, e) =>
{
if (global::System.Diagnostics.Debugger.IsAttached) global::System.Diagnostics.Debugger.Break();
};
#endif
This exception can be after first SelectionChandeg, but it can be too after second, third etc.
There is BlankPage1 XAML:

I file nested it using the File Nesting from Mads Kristensen , here is the thread: https://marketplace.visualstudio.com/items?itemName=MadsKristensen.FileNesting
so I have a Resources.xaml.cs on my ResourceDictionary
my problem is I want to set my QuantityTextBox Value on AddQytyButton and SubQytyButton click command, here is my click command event:
private void AddQytyButton_Click(object sender, Windows.UI.Xaml.RoutedEventArgs e)
{
//does not exist in the current context
QuantityTextBox.Text = "test";
}
OR
private void AddQytyButton_Click(object sender, Windows.UI.Xaml.RoutedEventArgs e)
{
Button btn = sender as Button;
// this is not working as null reference
var textbox = (btn.Parent as StackPanel).Children[1] as TextBox;
}
Thanks,
NicoTing
You should cast btn.Parent to a Grid instead of a StackPanel since you are using the former in your XAML.
var textbox = (btn.Parent as Grid).Children[1] as TextBox;

How I can count how many orders in answer from website and generate grids?
Thank's for help so much! :)
I have a problem I can not solve.
As you can see in the picture , there is a label , a textobx and a ScrollViewer .
Now , I have to update the ScrollViewer when the user searches through the textbox .
Part of an event every time you make a keydown .
So if I write Statut ... should put first in the file list with the names "statuto rai"
the list can have N elements

CodeBehind event code:
private void TextBox_KeyDown(object sender, System.Windows.Input.KeyEventArgs e)
{
string find = ((TextBox)sender).Text;
attachmentsList = attachmentsList.Where(x => x.Name == find).ToList();
InitializeComponent();
}
in practice I do the intelligiente research, so every time I insert a letter filtrale list , and print it again , of course real time .
I hope I explained myself .
Thank you
I see you use bindings, in this case there is a much better stuff to reach your goal. It's CollectionView.
Here is a simple app for you which more or less fullfill your requirements:
View
<StackPanel Orientation="Horizontal">
<Label Content="Search" />
<TextBox MinWidth="30" Text="{Binding FilterText, UpdateSourceTrigger=PropertyChanged}" />
</StackPanel>
<ListBox ItemsSource="{Binding Data}" />
UpdateSorceTrigger=PropertyChanges updates FilterText in ViewModel every time when you press any key.
Data is a ICollectionView
ViewModel
public ICollectionView Data { get; private set; }
...
// Create default view for the list
Data = CollectionViewSource.GetDefaultView(list);
// Set filter delegate for CollectionView
Data.Filter = FilterData;
....
private bool FilterData(object obj)
{
DataContainer cont = (DataContainer)obj;
return string.IsNullOrEmpty(FilterText) || cont.Name.StartsWith(FilterText, StringComparison.OrdinalIgnoreCase);
}
private string myfiltertext;
public string FilterText
{
get { return myfiltertext; }
set
{
myfiltertext = value;
// Refresh collection view after Filter text modification
Data.Refresh();
}
}

I have a button with binding as ClearCommand which clears the value of text box but it is not working.
public SellerDetailsViewModel() //constructor
{
sdObject = new SellerDetailsTable();
_SaveCommand = new RelayCommand(Save, CanSave);
_ClearCommand = new RelayCommand(clear, Canclear);
}
private readonly ICommand _ClearCommand;
public ICommand ClearCommand { get { return _ClearCommand; } }
public event PropertyChangedEventHandler PropertyChanged;
public void onPropertyChange(string propertyName)
{
if (PropertyChanged != null)
PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
}
public bool Canclear(object obj)
{
return true;
}
public void clear(object obj)
{
this.PancardNumber = "";
this.ContactNumber = 0;
this.FirstName = "";
this.LastName = "";
this.MiddleName = "";
this.OtherDocument = "";
this.Address = "";
}

I have debugged the code execution. clear function is executed but in the view, the textbox is not empty. Can you help me figure out what I am doing wrong?
I have added remaining code please what is missing.
You should post the rest of your xaml. Assuming your controls are TextBox's...
public void clear(object obj)
{
this.PancardNumber.Text = "";
this.ContactNumber.Text = "0"; //depends what this control is
this.FirstName.Text = "";
this.LastName.Text = "";
this.MiddleName.Text = "";
this.OtherDocument.Text = "";
this.Address.Text = "";
}
Try this, hope it helps.
public void clear(object obj)
{
this.PancardNumber = "";
this.ContactNumber = 0;
this.FirstName = "";
this.LastName = "";
this.MiddleName = "";
this.OtherDocument = "";
this.Address = "";
// should work on other document
OnPropertyChanged("OtherDocument");
}
<Button Content="Clear All" Command="{Binding ClearCommand}" FontSize="22" Height="37" HorizontalAlignment="Left" Margin="500,543,0,0" Name="btnClearAll" VerticalAlignment="Top" Width="131" />
<TextBox BorderThickness="2" Text="{Binding OtherDocument, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" Height="126" HorizontalAlignment="Left" Margin="205,399,0,0" Name="rchTxtOtherDoc" VerticalAlignment="Top" Width="257" FontSize="16" VerticalScrollBarVisibility="Visible" />
