Hi Gowtham,
Thanks for this. When I drop the item onto the grid I get the following error
System.Collections.Generic.KeyNotFoundException: The given key 'screenX' was not present in the dictionary
Also, once I drop the node I want to change it into an html element. I have tried the following,
public void OnDrop(IBlazorDropEventArgs args)
{
args.Cancel = true;
var NewNode = args.Element.Node;
Diagram.Nodes.Add(new DiagramNode()
{
OffsetX = NewNode.OffsetX,
OffsetY = NewNode.OffsetY,
Width = NewNode.Width,
Height = NewNode.Height,
Shape = new DiagramShape()
{
Type = Shapes.HTML,
}
});
}
but that only works with
<DiagramEvents OnDrop="@OnDrop"></DiagramEvents>
In the SFDiagram I have
<DiagramTemplates>
<NodeTemplate>
@{
<content><div>HTML here</div></content>
}
</NodeTemplate>
</DiagramTemplates>
