Description
This KB article demonstrates how we can implement a freehand drawing canvas in WinForms.
Solution
To achieve free hand typing or drawing in a WinForms application, we can use the InkCanvas element. To add the WPF object in WinForms Form, we can use the ElementHost class.
Note that InkCanvas is not a native WinForms control and requires additional assemblies (
PresentationCore,PresentationFramework, andWindowsFormsIntegration) to integrate with WinForms.
To use InkCanvas in a WinForms application, follow these steps:
ElementHost host = new ElementHost();
host.Dock = DockStyle.Fill;
InkCanvas ic = new InkCanvas();
host.Child = ic;
this.radPanel1.Controls.Add(host);
