I want to set text in TextBoxes that are defined in an loaded loose xaml file. The TextBoxes are part of the application.
StackPanel LooseRoot;
if (fTeleFound == true)
{
try
{
using (System.IO.FileStream fs = new System.IO.FileStream(sXamlFileName, System.IO.FileMode.Open))
{
LooseRoot = (StackPanel)System.Windows.Markup.XamlReader.Load(fs);
}
this.DetailsViewFrame.Children.Add(LooseRoot);
}
catch (ArgumentException ex)
{
// TBD Error xamlfile
return;
}
// set Elements
//foreach (TextBox textBox in LooseRoot.Children as TextBox) // does not work ?
//{
//
//}
}
The xaml file is like this:
<StackPanel Margin="10" Orientation="Vertical"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<StackPanel Orientation="Horizontal">
<Label Margin="5,5,0,5">CRCDB=</Label>
<TextBox Margin="0,5,5,5" Name="DetailsviewTB1" Height="20"/>
<Label Margin="10,5,0,5">Infonummer=</Label>
<TextBox Margin="0,5,5,5" Name="DetailsviewTB2" Height="20"/>
<Label Margin="10,5,0,5">Daten=</Label>
<TextBox Margin="0,5,5,5" Name="DetailsviewTB3" Height="20"/>
</StackPanel>
This is for a details view that has to be customizable without compiling the application new. The amount of loose xaml files and their names are not known at compiling time.
How can i set the Text on the TextBoxes dynamicly? I have a additional xml-File that can specify what data comes in which TextBox.
Can you bind them? If so i would definitely recommend doing that, then you just need to set the
DataContext
to an object containing the values.Else you can monkey around with
Logical
andVisualTreeHelpers
, looking for a TextBox with the right name recursively. You can also tryFindName
on someFrameworkElement
containing yourStackPanel
.
