How to avoid the Text boxes having no values but the borders property is set as Solid ?

When we create Text Boxes in VS while report Transformation and their Border property is set to Solid, then if

there is any values come in that text box there are borders in but if there are no values then also the borders print.

Can we avoid it?

You could try having two text boxes with the Visibility property set to an expression. That expression would if the value is not equal to zero or not equal to empty string display the box with the border, otherwise display the box without one.
