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
