Hi,

In demo application there is an application NetSample which demonstrates that nodes can be created by clicking and also text can be attached to it.

The issue here is that when we delete the node, only the image is getting deleted not the text itself.

Also i would like to know how to achieve following in regard to this sample -
1) We will provide a toolbar that will have images of building, Printer etc. Clicking on one of them will change the wpfdiagram cursor and then clickin on the diagram sheet will draw the corresponding node object and cursor will then change to default and subsequent clicks should not then create node objects until any object from the toolbar is selected again.
2) Above feature should also work in case of links that is there will be a toolbar with different type of link objects and clicking on a link object of tollbar will change the wpf diagram cursor to pen and then we would be able to create links between two nodes and without clicking on link objects the user should not be allowed to create links between objects.
3) The associated text should also get deleted with the node.

Thanks,

Hi,

In the same demo application (NetSample) can you suggest me how to align text attached to the node dynamically so that it can be  aligned left/right/top/bottom in respect to the node.

In the sample created by you to get above thing done you said the text region definition needs to be changed how can it be done for all the diagram nodes dynamically (say on a button click)

Thanks,

Thanks for the reply. I tried it but it seems that it is taking top-left of the node. The thing i want is that the text and node should be disjoint and they should look like separate entity. like this :
1) Say for top alignment:
<Text>
<node>
2) for left alignment
<Text><node>

So, what to do in above case. As we may have a requirement in which a user may opt for left text alignment instead of default bottom, and in that case it does not look good to change my custom shape for each of the diagram node to reflect left text alignment. How to solve this problem?

I think it should be added as a new feature.

Thanks for the reply.

I think the NetSample example is using the transparent node attached.

I tried altering it as per my requirements but not getting any result.

For my requirement i think that i have to add 4 transparent nodes left/right/top/bottom.

Can you present some codelines to do this also i would like that on button click the text alignment of all the nodes should change.

Thanks,

Thanks i will try this and let you know.

I have one more query

1) I have written following code for custom shape node:

[code]
shapeNode = new MindFusion.Diagramming.Wpf.Shape(new ElementTemplate[]{
new LineTemplate(50, 0, 100, 50),
new LineTemplate(100, 50, 50, 100),
new LineTemplate(50, 100, 0, 50),
new LineTemplate(0, 50, 50, 0),
},null,
new ElementTemplate[]{
new LineTemplate(0, 100, 100, 100),
new LineTemplate(100, 100, 100, 150),
new LineTemplate(100, 150, 0, 150),
new LineTemplate(0, 150, 0, 100)
}, FillRule.Nonzero, "");

ShapeNode node = new ShapeNode(diagram);
node.Bounds = new Rect(new Point(100, 100), new Size(45, 45));
Uri uri = new Uri(@"..\..\Test.png", UriKind.RelativeOrAbsolute);
node.Image = new BitmapImage(uri);
node.ImageAlign = ImageAlign.Center;
node.TextFormat.Alignment = StringAlignment.Center;
node.Text = "Hello Test";
[/code]

The problem with above code is that the text attached to the node i.e. "Hello Test" is getting clipped and we see only "Hello". What we like here is that the text can be given of any length and the text region should adjust its width accordingly.

How to achieve this?

Thanks,
Anurodh

Thanks for the reply.

Tried this, its not working (still only "Hello" is appearing) and second thing we do not want our node region to resize only text region width should be adjusted according to the text length.

Hi,

I tried attached node method see below code for example:

[code]
ShapeNode mainNode = diagram.Factory.CreateShapeNode(
new Point(100, 100), new Size(45, 45));
Uri uri = new Uri(@"..\..\Test.png", UriKind.RelativeOrAbsolute);
mainNode.Image = new BitmapImage(uri);
mainNode.ImageAlign = ImageAlign.Center;
mainNode.Shape = Shapes.Decision;
mainNode.EnabledHandles = AdjustmentHandles.Move;

ShapeNode labelNode = diagram.Factory.CreateShapeNode(
mainNode.Bounds.X - 10, mainNode.Bounds.Y + mainNode.Bounds.Height,
mainNode.Bounds.Width + 20, 15);

labelNode.AttachTo(mainNode, AttachToNode.MiddleLeft);
labelNode.Locked = true;
labelNode.Transparent = true;
labelNode.Text = "This is a long text string";

labelNode.ResizeToFitText(FitSize.KeepHeight);
[/code]

Then also the text is getting clipped along the width but when i change ResizeToFitText(FitSize.KeepHeight) to ResizeToFitText(FitSize.KeepWidth) full text can be seen as wrapped one but the problem is i want to keep text height as it is and the label node should resize in width.

Can you suggest. What i am missing here?

Thanks in advance,
Anurodh

Thanks for the reply.

Tried but not working same problem.
