Computes the location of the specified client point into screen coordinates.
Returns: . A that represents the converted , point , in screen coordinates.
Forces the control to update the corresponding client widget. When in DesignMode it forces a full redraw of the designer surface for this control and optionally of its children, including the non-client areas such as the caption of forms or panels.
Removes an owned form from this form.
Shows the form to the user.
Forms are disposed immediately when they are closed and cannot be shown again. The optional onclose parameter is an asynchronous callback handler invoked when the form is closed. It is similar to handling the event.
Throws:
The form being shown is already visible; or the form being shown is not a top-level window; or the form being shown as a dialog box is already a modal form.
Shows the form with the specified owner to the user.
Forms are disposed immediately when they are closed and cannot be shown again. The optional onclose parameter is an asynchronous callback handler invoked when the form is closed. It is similar to handling the event.
Throws:
The form being shown is already visible; or The form specified in the owner parameter is the same as the form being shown; or the form being shown is disabled; or the form being shown is not a top-level window; or the form being shown as a dialog box is already a modal form.
Shows the form as a modal dialog box. When the onclose is specified, the dialog is modal only in the browser.
Returns: . One of the values.
When using ShowDialog, the dialog instance is not automatically disposed when the dialog is closed because dialogs are reusable. To make sure that memory is released properly, you must dispose the instance in your code or use the typical using pattern. Dialogs that are closed, but not disposed and not referenced by the application will be disposed by the Garbage Collector when it kicks in.
Modal dialogs suspend the code execution on the server side effectively replicating the full modal workflow employed by desktop applications. However, when the optional onclose parameter is specified, the dialog is modal only in the browser and doesn't suspend the server thread. Which is similar to the typical asynchronous modal pattern used in javascript.
Throws:
The form being shown is already visible; or the form being shown is disabled; or the form being shown is not a top-level window; or the form being shown as a dialog box is already a modal form.
Shows the form as a modal dialog box with the specified owner. When the onclose is specified, the dialog is modal only in the browser.

Asynchronously shows the form as an awaitable modal dialog box.
Returns: . An awaitable that contains the value returned asynchronous when the user closes the modal dialog.

Asynchronous Modal dialogs don't suspend the code execution on the server side but can be "awaited" in "async" methods effectively replicating the full modal workflow employed by desktop applications in an asynchronous environment.
Throws:
The form being shown is already visible; or the form being shown is disabled; or the form being shown is not a top-level window; or the form being shown as a dialog box is already a modal form.
Converts the client size into the window size.
Returns: .
Fired when the form is activated in code or by the user.
Fired when the form loses focus and is no longer the active form.
Occurs after the form is closed.
Occurs before the form is closed.
Fired when the Help button is clicked.
