Asp. NET Visible attributes and HTML display: none, asp. netvisible

 

As an Asp. NET program, we often encounter interoperability between HTML elements on the client and controls on the WebPage Server. If you do not have a good grasp of the details of the two technologies, it is easy to make some "inexplicable errors ".

One of the most recent mistakes I made was to use the Jquery selector on the client to obtain the HTML elements generated by the server control after assigning the Visible attribute of the server control to False, after several debugging attempts, I used the IE F12 development tool> DOM Resource Manager to find that this element does not exist in the DOM. On MSDN, view the Visible definition discovery. When its property value is set to False, IIS does not generate corresponding page elements in response to the WebPage request from the client.

To learn more, we need to know the specific definition of the CSS style attribute display, as shown below for the sake of warmth.

Browser support

All mainstream browsers support the display attribute.

Definition and usage

The display attribute specifies the type of the box that the element should generate.

Possible Value

Value	Description
None	This element is not displayed.
Block	This element is displayed as a block-level element with a line break before and after it.
Inline	Default value. This element is displayed as an inline element, and there is no line break before and after the element.
Inline-block	The block element in the row. (Newly added value of CSS2.1)

 

 

Browser support

All mainstream browsers support the visibility attribute.

Definition and usage

The visibility attribute specifies whether the element is visible.

Tip: even invisible elements occupy space on the page. Use the "display" attribute to create invisible elements that do not occupy the page space.

Description

This attribute specifies whether to display the element box generated by an element. This means that the element still occupies its original space, but it can be completely invisible. The value collapse is used to delete columns or rows from the table layout.

Possible Value

Value	Description
Visible	Default value. The element is visible.
Hidden	The element is invisible.
Collapse	When used in table elements, this value can be used to delete a row or column, but it does not affect the layout of the table. The space occupied by rows or columns is reserved for other content. If this value is used on other elements, It is displayed as "hidden ".
Inherit	Specifies that the value of the visibility attribute should be inherited from the parent element.
