Text not resizing on resizing node?

I am using gojsNode and text property bind with it.On resizing node i want that text should be resizable.

What you are saying can be interpreted several different ways. Could you show us before and after screenshots of what you want to happen?

After Resizing

On resizing this node text"Numeric10002" could not resizable .

How did resizing change the text string?

If you want the TextBlock to be scaled larger to fit in the larger area, put it inside a “Viewbox” Panel. GoJS Panels -- Northwoods Software
