Thanks for the Reply Walter.
Issue:
I can drag the node and can put on the right side borders.
I am using the sample code from GOJS only (it is not my application). Pasting my whole code for your reference.
Sample code from GOJS:
// define a custom ResizingTool to limit how far one can shrink a row or column
function LaneResizingTool() {
go.ResizingTool.call(this);
}
go.Diagram.inherit(LaneResizingTool, go.ResizingTool);
/** @override */
LaneResizingTool.prototype.computeMinSize = function() {
var diagram = this.diagram;
var lane = this.adornedObject.part; // might be row or column
var horiz = (lane.category === "Column Header"); // or "Row Header"
var margin = diagram.nodeTemplate.margin;
var bounds = new go.Rect();
diagram.findTopLevelGroups().each(function(g) {
if (horiz ? (g.column === lane.column) : (g.row === lane.row)) {
var b = diagram.computePartsBounds(g.memberParts);
if (b.isEmpty()) return; // nothing in there? ignore it
b.unionPoint(g.location); // keep any empty space on the left and top
b.addMargin(margin); // assume the same node margin applies to all nodes
if (bounds.isEmpty()) {
bounds = b;
} else {
bounds.unionRect(b);
}
}
});
// limit the result by the standard value of computeMinSize
var msz = go.ResizingTool.prototype.computeMinSize.call(this);
if (bounds.isEmpty()) return msz;
return new go.Size(Math.max(msz.width, bounds.width), Math.max(msz.height, bounds.height));
};
/** @override */
LaneResizingTool.prototype.resize = function(newr) {
var lane = this.adornedObject.part;
var horiz = (lane.category === "Column Header");
var lay = this.diagram.layout; // the TableLayout
if (horiz) {
var col = lane.column;
var coldef = lay.getColumnDefinition(col);
coldef.width = newr.width;
} else {
var row = lane.row;
var rowdef = lay.getRowDefinition(row);
rowdef.height = newr.height;
}
lay.invalidateLayout();
};
