Hi,

I asked this before, but it was probably lost in a rather long thread.
I'm using the svg and code behind shown below.
The issue is that the shape does not fill the palette item and looks rather small - see attached screenshot.
What do I need to do to ensure that the shape fills as much of the palette item as possible?

Also, is it possible to show a different image in the palette than what gets dropped on the canvas?
For example, what if we only showed the image in the upper left corner of the shape in the attachment, rather than the whole shape?

Any suggestions much appreciated.

Jim

The code behind:

        Node scriptTask = new Node();
        scriptTask.Shape = new Shape(Shapes.Native);
        scriptTask.Shape.ContentId = "ScriptTask";
        scriptTask.Name = "Script Task";
        scriptTask.OffsetX = 150;
        scriptTask.OffsetY = 250;
        scriptTask.Width = 137;
        scriptTask.Height = 81;

The palette item width and height values are set to 45.

Hi Jim

Thanks for using Syncfusion products.

Query

Response

The issue is that the shape does not fill the palette item and looks rather small - see attached screenshot.
What do I need to do to ensure that the shape fills as much of the palette item as possible?

Please note that the node’s rendering into the palette on the basis of node’s “Width” and “Height” properties and symbolPalette’s “PaletteItemWidth” and “PaletteItemHeight” properties. The “Width” and “Height” properties for the node that you have provided is greater than the symbolPalette’s “PaletteItemWidth” and “PaletteItemHeight” properties so that it is translated to very small size and appends in the palette. We suggest you to set the node’s “Width” and “Height” properties as follows so that the node fits correctly into the palette.

Here is the code snippet

Node node2 = new Node();

node2.Name = "natives";

node2.Width = 40;

node2.Height = 40;

node2.OffsetX = node2.Width/2;

node2.OffsetY = node2.Height/2;

We suggest you to use "drop" event to change the Node's "Width" and "Height" properties and this event triggered when the node is dropped inside the diagram area(canvas).

Here is the code snippet

DiagramContent.ClientDrop = "drop";

function drop(args) {

if (args.element.shape) {

var node = args.element;

node.width = 100;

node.height = 100;

}

Also, is it possible to show a different image in the palette than what gets dropped on the canvas?
For example, what if we only showed the image in the upper left corner of the shape in the attachment, rather than the whole shape?

Please note that the node’s preview in the palette will be same as we drop inside the canvas and it is default behavior of our control. Currently we don’t have support to render a different preview in the canvas compared to palette during drag and drop. However, we have achieved your requirement using the “add Info” property of node and “drop” event.

As per your requirement, we set an id of group child element(upper left corner shape) to the “node2.Shape.ContentId” so that it renders the group child element(upper left corner shape) in the palette.

We have set an id of group parent element(whole shape) to the “add info” property of the node. When an element(upper left corner shape) is drag and dropped onto the canvas, we use “drop” event to get the id of group parent element(whole shape) and set to the node’s content and will update the node using updateNode API.

Please see the code snippet below and sample is attached below

id="path6536-2"

style="fill: #58595b" />

</g>

</svg>

Native node:

Node node2 = new Node();

node2.Name = "natives";

node2.Shape = new Shape(Shapes.Native);

node2.Shape.ContentId = "sorrytask";

Dictionary<string, object> addInfo = new Dictionary<string, object>();

addInfo.Add("Id", "ScriptTask");

node2.AddInfo = addInfo;

Here is the code snippet to trigger drop event.

DiagramContent.ClientDrop = "drop";

function drop(args) {

if (args.element.shape) {

var node = args.element;

if (node.addInfo.Id) {

//gets the id of SVG element

var svg = document.getElementById(node.addInfo.Id);

var child = svg.lastElementChild.firstElementChild;

child.setAttribute('transform', 'translate(-257.23333,-247.97111)');

//update the node

diagram.updateNode(node.name, { shape: { content: svg, type: "native" } });

}

Please let me know if any concerns.

Regards,

Shyam G
