Button

Common action buttons.

The underlying button usage.

Demo

Display different button styles by setting the ButtonStyle

Demo

Set the color style of the button border by setting the IsOutline='true'.

Demo

The Button component provides a variety of sizes in addition to the default values, and by setting the Size property, you can select the appropriate button size in different scenarios.

Demo

Button is not available. By setting the IsDisabled property

Demo

Button disable effects can be achieved by setting its own IsDisabled property in the OnClick callback method, or by calling the component instance method SetDisable

Because using the IsDisabled property requires an explicit manual call to the StateHasChanged method, which causes the component where the button is located to refresh as a whole, it is recommended that you use the instance method SetDisable refresh the button only

Performance comparison:

  • This page transfer is 4.8K when set with the IsDisabled property
  • This page transfer is 280B when set up using the SetDisable method

A combination of multiple buttons

Demo

Set the button icon by setting the Icon property, which is fa-fa when using font strings such as the font-awesome icon

Demo

The button display text is set by setting the Text property of the winButton component, and the click button is the text on the right that shows the clicked button

Demo

By setting whether the isAsync property button is asynchronous request button by setting whether the is false by default

Demo

When the button is an asynchronous request button, the button is changed to disabled, and the loading small icon is displayed, returning to normal after the asynchronous request ends, in this case, after clicking the asynchronous request button, the request load animation is displayed and returns to normal after 5 seconds
