Show size value when Table resize column or row

I want to show a text box or something when drag to resize the column or rows.
Like Microsoft excel resizing columns, Is there any idea to do this?
I using the this sample’s resizing tools.

also like this sample when resizing the column show DimensioningLink is most cool! :)

Sure – customize the ColumnResizingTool so that doActivate also shows the information you want to show in a separate Adornment at an appropriate location and so that doDeactivate hides it, and augment the resize method to also update that new Adornment.

Thank you, Point to the road for me. I will try it.

Here’s an example: RotatingTool showing current angle

Thank you.
