Source Code

Imports System.Runtime.CompilerServices

		<Extension()> Public Sub AddConfirmation(ByVal btn As Button)
			btn.AddConfirmation(String.Format("Are you sure you want to click the {0} button?", btn.Text))
		End Sub
		<Extension()> Public Sub AddConfirmation(ByVal btn As Button, ByVal msg As String)
			btn.OnClientClick = String.Format("return window.confirm('{0}');", msg)
		End Sub
		<Extension()> Public Sub AddConfirmation(ByVal btn As ImageButton)
			btn.AddConfirmation(String.Format("Are you sure you want to click the {0} button?", btn.AlternateText))
		End Sub
		<Extension()> Public Sub AddConfirmation(ByVal btn As ImageButton, ByVal msg As String)
			btn.OnClientClick = String.Format("return window.confirm('{0}');", msg)
		End Sub
		<Extension()> Public Sub AddConfirmation(ByVal btn As LinkButton)
			btn.AddConfirmation(String.Format("Are you sure you want to click the {0} button?", btn.Text))
		End Sub
		<Extension()> Public Sub AddConfirmation(ByVal btn As LinkButton, ByVal msg As String)
			btn.OnClientClick = String.Format("return window.confirm('{0}');", msg)
		End Sub
	End Module
End Namespace

Remarks

	We all know that it is not hard to manually add a confirmation, either declaratively or programmatically, so why would I bother to make this Extension Method? Well, mostly just because I enjoy writing code, but it can make things easier when you want to dynamically generate the confirmation message.
