Hi,

1. You can use GetCellBounds to get the bounding rectangle of the lane, and then check if it intersects with the node:

var grid = diagram.LaneGrid;
Rect r = grid.GetCellBounds(grid[...]);
var laneNodes = from DiagramNode node in diagram.Nodes where node.Bounds.IntersectsWith(r) select node;

2. Using an expression as above, but change the where clause to 'where node is MyNodeType'.

I hope that helps,

Hi,

1. You can use the [Header, Header] indexer overload to get an ICell representing a whole row or column, by setting respectively the column or row header arguments to null. Then calling GetCellBounds() on that ICell will return the bounding rectangle for the whole row or column.

2. I suppose you could handle the ItemAdded event and if the new item is the node type displayed in the grid, add it to the list from the initial query.

I hope that helps,

Hi,

You can handle the NodeTextEdited event to detect text changes, or you might try binding to DiagramItem.Text - it is a dependency property.

I hope that helps,

Hi,

1. I suppose that depends on the grid control you are using. If it's the one from the WPF Toolkit, you can find an example here:

2. It doesn't. By handling ItemAdded as above, you could add the specific type of nodes to an ObservableCollection and set it as the grid's source.

I hope that helps,
