Controls at a glance

Controls in detail

FileTextBox

A TextBox pre-wired for file path entry. Users can type a path directly, click the browse button, double-click the text box, or simply drag and drop a file from Explorer. A full context menu covers cut, copy, paste, undo, redo, select-all, clear and open-file.

xmlns:cs="clr-namespace:Casasoft.Xaml.Controls;assembly=Casasoft.Xaml.Controls"
...
<cs:FileTextBox x:Name="myFilePicker"
                OpenFileDialogFilter="Images (*.png;*.jpg)|*.png;*.jpg|All files (*.*)|*.*"
                OpenFileDialogTitle="Choose an image" />

string path = myFilePicker.Value;   // read the chosen path
myFilePicker.Value = @"C:\default"; // set a default path

Key properties

FileTextBoxLabel

A thin composite control that stacks a Label above a FileTextBox. Handy when you need a labelled file picker without writing extra XAML every time.

<cs:FileTextBoxLabel Caption="Input file"
                     OpenFileDialogFilter="Text files (*.txt)|*.txt"
                     OpenFileDialogTitle="Select a text file" />

Key properties — all of FileTextBox, plus:

NumericUpDown

A compact integer spinner with Up/Down buttons, keyboard input validation (digits and leading minus only) and configurable range clamping.

<cs:NumericUpDown x:Name="spinner"
                  MinValue="0" MaxValue="100" Step="5" />

spinner.Value = 42;
int current = spinner.Value;

Key properties

ImageViewer

A self-contained image viewer with mouse-driven pan, scroll-wheel zoom, and a context menu for flip (horizontal/vertical) and rotation (90°, 180°, 270°, free). All transformations are composited through a single TransformGroup for predictable rendering.

<cs:ImageViewer x:Name="viewer" BorderBackground="Black" />

viewer.Source = new BitmapImage(new Uri("photo.jpg", UriKind.Relative));

// Programmatic control
viewer.Rotate(90);
viewer.FlipHorizontal();
viewer.Zoom(0.5);
viewer.Reset();

Key members

TextEditor

A multi-line TextBox wrapper with a complete editing experience out of the box:

• Open / Save dialogs (configurable filter, title, default extension)
• Drag and drop — drop a file to load it, or drop plain text to insert it
• Context menu with cut, copy, paste, undo, redo, select-all, select-line, clear, load, save
• Public API for all editing actions (suitable for toolbar buttons)
• Markup helpers — wrap the current selection with arbitrary markup or paired XML tags

<cs:TextEditor x:Name="editor"
               OpenFileDialogFilter="Markdown (*.md)|*.md|All files (*.*)|*.*"
               SaveFileDialogFilter="Markdown (*.md)|*.md|All files (*.*)|*.*"
               SaveFileDefaultExt="md" />

editor.Value = File.ReadAllText("draft.md");
editor.AddTagToSelection("b");           // wraps selection with <b>...</b>
editor.AddMarkupToSelection("**", "**"); // wraps selection with **...**
editor.SaveFile();

Key members

PangoTextEditor

A TextEditor pre-configured for Pango markup, with a built-in toolbar providing Open, Save, New, Undo, Redo, Bold and Italic buttons. The file dialog defaults to .pango files.

<cs:PangoTextEditor x:Name="pangoEditor" />

pangoEditor.Value = "pango:<span>Hello <b>world</b></span>";
string markup = pangoEditor.Value;
