This article is to share with you about how to use Attributes.Add. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Attributes.Add usage and usage, Attributes.Add ("javascript event", "javascript statement").

Use of Attributes.Add

This.TextBox1.Attributes.add ("onblue", "window.Label1.style.backgroundColor='#000000';")

This.TextBox1.Attributes.Add ("onblur", "this.style.display='none'")

Events triggered by onMouseOut when the mouse leaves the scope of an object

OnKeyPress an event that is triggered when a key on the keyboard is pressed and released. [note: there must be focused objects in the page]

OnKeyDown event triggered when a key on the keyboard is pressed [Note: there must be focused objects on the page]

OnKeyUp event triggered when a key on the keyboard is pressed and released [Note: there must be focused objects on the page]

Attributes.Add usage

The addition of too much Attributes.Add will affect a certain speed, and after Attributes and Attributes.CssStyle are automatically saved to ViewState, in addition to the rapid increase in the volume of ViewState, the burden of LoadViewState in PostBack also increases.

Add to the following event, in the following form:

ProtectedoverridevoidRender (HtmlTextWriteroutput)

{

This.Attributes ["abc"] = "123"

This.Attributes.CssStyle ["abc-style"] = "123-style"

Output.Write (Text)

}

Attributes and Attributes.CssStyle will no longer be saved to ViewState
