i'm trying to use 'Nevron.UI.WinForm.Controls.NGalleryPanel', using 'NGalleryItem'.
Now i want to implement 'drag and drop' in NGalleryPanel.
'''code'''
private void Form1_DragDrop(object sender, DragEventArgs e)
{
NGalleryItem data = (NGalleryItem)e.Data.GetData(typeof(NGalleryItem));
NGalleryPanel galleryPanel = (NGalleryPanel)sender;
Point p = galleryPanel.PointToClient(new Point(e.X, e.Y));
var item = galleryPanel.GetChildAtPoint(p);
int index = galleryPanel.Controls.GetChildIndex(item, false);
galleryPanel.Controls.SetChildIndex(data, index);
galleryPanel.Invalidate();
}
galleryPanel.Controls.SetChildIndex(data, index);
this cause error because "NGalleryItem" is not a control..
How can i implement drag and drop in NGalleryPanel??
