So on my Default.aspx page I have several listboxes which I am populating on page_load.However, if the user changes these listboxes and wants to restore the original settings, I want a button at the top, which is defined in the Site.Master, to call this same function gain to restore the original values.How can I obtain a reference to an instance of the _Default object from the Site.Master file? Is there a way to globally access the instance of _Default that is called when the page is first loaded? Or do I need to store that manually somewhere?For exampleefault.aspx.cs:\[code\]namespace WebApplication1{ public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { setConfigurationData(); } public void setConfigurationData() { //Do stuff to elements on Default.aspx\[/code\]Site.Master.cs\[code\]namespace WebApplication1{ public partial class SiteMaster : System.Web.UI.MasterPage { protected void Page_Load(object sender, EventArgs e) { } protected void RefreshMenu1_MenuItemClick(object sender, MenuEventArgs e) { //Need to call this function from an instance of _Default, but I don't know //how to retrive this or save it from when it is first created //_Default.setConfigurationData();\[/code\]
