Dynamic DesignItem

[khalili-mahdi]

is there any way i can add designItem to designSurface dynamically ?

[jogibear9988]

Sure:

var changeGroup = designItemContainer.OpenGroup("blabla");
var button = new Button();
var buttonDesignItem = designItemContainer.Services.Component.RegisterComponentForDesigner(button);
designItemContainer.ContentProperty.CollectionElements.Add(buttonDesignItem);
changeGroup.Commit();

i did this: var designItemContainer = designSurface.DesignContext.RootItem; var changeGroup = designItemContainer.OpenGroup("blabla"); var button = new Button(); var buttonDesignItem = designItemContainer.Services.Component.RegisterComponentForDesigner(button); designItemContainer.ContentProperty.CollectionElements.Add(buttonDesignItem); changeGroup.Commit(); TY , can i change position of item in designPanel?

[jogibear9988]

sure:

 buttonDesignItem.Properties.GetAttachedProperty(Canvas.LeftProperty).SetValue(130.0);

almost solved problem but there is a little issue here this does not changed my control position, i cant upload whole project , here is my base control

i have my own control and i create my own PropertyGrid with dynamic properties which is working but in design setting Canvas.LefProperty does not works, i know you have PropertyGrid but that is for your designItems which i have my own

[jogibear9988]

Don't know what you mean! You have your own Property Grid, which one?

You need to change the Properties of the DesignItem, not of the View or Component, or the XAML will not be changed. If you use your own Property Grid, maybe it has a event when a Property is changed wich you could use?

You could also change what our PropertyGrid is showing (see #45)

[jogibear9988]

Maybe I've time next week to add a Example how I used "DesignItemBinding" to create my special Property Editors for some controls.

[khalili-mahdi]

i have a list of controls which i make them from a xml file public List<BaseControl> Controls { get; private set; } = new List<BaseControl>(); then i want to load this controls to view

foreach (BaseControl control in fd.Controls)
            {
                var designItemContainer = designSurface.DesignContext.RootItem;
                var changeGroup = designItemContainer.OpenGroup("blabla");

                var ControlDesignItem = designItemContainer.Services.Component.RegisterComponentForDesigner(control);
                //ControlDesignItem.Properties.GetAttachedProperty(Canvas.WidthProperty).SetValue(230.0);
                //ControlDesignItem.Properties.GetAttachedProperty(Canvas.HeightProperty).SetValue(230.0);
                ControlDesignItem.Properties.GetAttachedProperty(Canvas.RightProperty).SetValue(130.0);
                ControlDesignItem.Properties.GetAttachedProperty(Canvas.BottomProperty).SetValue(130.0);
                ControlDesignItem.Properties.GetAttachedProperty(Canvas.LeftProperty).SetValue(130.0);
                ControlDesignItem.Properties.GetAttachedProperty(Canvas.TopProperty).SetValue(130.0);

                designItemContainer.ContentProperty.CollectionElements.Add(ControlDesignItem);
                changeGroup.Commit();
            }

this is showing my control but my control is full size in DesignSurface i can resize controls from designSurface UI but i am looking for a way to resize them with code and Canvas.LeftProperty does not works

[khalili-mahdi]

i think maybe there is a property which setting my control row and col in grid , so i have 1 row and 1 col and its showing full size , so Can i set margin? i tried this : ControlDesignItem.Properties.GetAttachedProperty(Canvas.MarginProperty).SetValue(new Thickness(130));

[jogibear9988]

If your Container is a Grid, Canvas.LeftProperty will have no Effect! And Margin is not an Attached Property, use GetProperty(FrameworkElement.MarginProperty... And the Value of the Margin needs to be a „new Thickness(...“

[khalili-mahdi]

GJ man ,ty for your fast answers yeah this is working ControlDesignItem.Properties.GetProperty(FrameworkElement.MarginProperty).SetValue(new Thickness(130)); if i want to use Canvas.MarginProperty what container should i use?

[jogibear9988]

Canvas.MarginProperty is same a Frameworkelement.MarginProperty (its a Derived Static Field). If you want to use Canvas.LeftProperty you should use a Canvas as a Container
