Display/hide controls on the client side

Set the display adequacy in the style of the control:

When the value is displayed as "", it is the implicit display; when the value is none, it is hidden!

The method for setting the sensitivity on the client side: Document. getelementbyid ("ID"). style. Display = ""/"NONE ";

This. Id. style. Add ("display", ""/"NONE ");

If you only set whether the control is displayed on the server side, you can directly set the visibility of the control.

However, if you want to enable this feature on the client side, you cannot set this feature. Because when visible is set to false, the control cannot be found on the client side, in addition, it is impossible to set its adequacy.
