在画布中的WPF中在画布上拖动dynamica控件，而不在其他控件上重叠. [英] dragging dynamica control on canvas in wpf within canvas and not overlapping on other.

问题描述

朋友，

我已经引用了代码WPF图表设计器:第1部分

并更新了我的想法，如下所示

Hi Friends,

i have referred code WPF Diagram Designer: Part 1

and updated with my idea as follows

private void button1_Click(object sender, RoutedEventArgs e)
       {
           System.Windows.Shapes.Ellipse lb = new System.Windows.Shapes.Ellipse();
           lb.IsHitTestVisible = false;
           lb.Name = "dynecp";
           lb.Fill = System.Windows.Media.Brushes.DeepSkyBlue;

           System.Windows.Controls.ContentControl contcrl = new System.Windows.Controls.ContentControl();
           contcrl.MinHeight = 35;
           contcrl.MinWidth = 90;
           contcrl.Height = 40;
           contcrl.Width = 120;
           contcrl.Content = lb;
           contcrl.Name = "iamdyn";

           contcrl.Template = this.Resources["DesignerItemTemplate"] as ControlTemplate;
           contcrl.ApplyTemplate();
           contcrl.Margin = new System.Windows.Thickness(10, 10, 0, 0);

           DesignerCanvas.Children.Add(contcrl);
       }

在这里，我可以控制画布的大小，但无法调整大小.

有人可以帮忙吗?

谢谢.

here i am able to take control on canvas which resizes but not not moving around.

could someone please help ??

thank you.

推荐答案

System.Windows.Shapes.Ellipse lb = new System.Windows.Shapes.Ellipse();
            lb.IsHitTestVisible = false;
            lb.Name = "dynecp";
            lb.Fill = System.Windows.Media.Brushes.DeepSkyBlue;
            
            System.Windows.Controls.ContentControl contcrl = new System.Windows.Controls.ContentControl();
            contcrl.MinHeight = 35;
            contcrl.MinWidth = 90;
            contcrl.Height = 40;
            contcrl.Width = 120;
            contcrl.Content = lb;
            contcrl.Name = "iamdyn";
         
            Canvas.SetLeft(contcrl, 30);
            Canvas.SetTop(contcrl, 40);
            contcrl.Template = this.Resources["DesignerItemTemplate"] as ControlTemplate;
            contcrl.ApplyTemplate();
            tes1t.Children.Add(contcrl);

感谢您调查问题.

问题终于解决了

Thanks for looking into problem.

problem solved finally

System.Windows.Shapes.Ellipse lb =新的System.Windows.Shapes.Ellipse();
lb.IsHitTestVisible = false;
lb.Name ="dynecp";
lb.Fill = System.Windows.Media.Brushes.DeepSkyBlue;

System.Windows.Controls.ContentControl contcrl =新的System.Windows.Controls.ContentControl();
contcrl.MinHeight = 35;
contcrl.MinWidth = 90;
contcrl.Height = 40;
contcrl.Width = 120;
contcrl.Content = lb;
contcrl.Name ="iamdyn";

Canvas.SetLeft(contcrl，30);
Canvas.SetTop(contcrl，40);
contcrl.Template = this.Resources ["DesignerItemTemplate"]作为ControlTemplate;
contcrl.ApplyTemplate();
tes1t.Children.Add(contcrl);

System.Windows.Shapes.Ellipse lb = new System.Windows.Shapes.Ellipse();
lb.IsHitTestVisible = false;
lb.Name = "dynecp";
lb.Fill = System.Windows.Media.Brushes.DeepSkyBlue;

System.Windows.Controls.ContentControl contcrl = new System.Windows.Controls.ContentControl();
contcrl.MinHeight = 35;
contcrl.MinWidth = 90;
contcrl.Height = 40;
contcrl.Width = 120;
contcrl.Content = lb;
contcrl.Name = "iamdyn";

Canvas.SetLeft(contcrl, 30);
Canvas.SetTop(contcrl, 40);
contcrl.Template = this.Resources["DesignerItemTemplate"] as ControlTemplate;
contcrl.ApplyTemplate();
tes1t.Children.Add(contcrl);
