Here is a C++ CLR function to draw OpenCV mat on any Windows Form Control:

void DrawCVImage(System::Windows::Forms::Control^ control, cv::Mat& colorImage)
{
    System::Drawing::Graphics^ graphics = control->CreateGraphics();
    System::IntPtr ptr(colorImage.ptr());
    System::Drawing::Bitmap^ b  = gcnew System::Drawing::Bitmap(colorImage.cols,colorImage.rows,colorImage.step,System::Drawing::Imaging::PixelFormat::Format24bppRgb,ptr);
    System::Drawing::RectangleF rect(0,0,control->Width,control->Height);
    graphics->DrawImage(b,rect);
    delete graphics;
}

This function can only draw 8 bit 3 channel images.

Try experimenting with Pixel Format of the bitmap for other image types.
