1. web user control within a web user control

Have web user control that contains four buttons and one a user clicks
a button another web user control is posted to the placeholder.  My
question is after the user enters some data into the textbox and
clicks submit, the child web user control goes away( which i
understand as page_load being called for parent web user control ) and
my database code never gets executed.  I load the child web user
controls dynamically, which is rendered from the use selecting a
particular button.  I have seen several responses to this, but nothing
that as provided answer.  I do understand that the child web user
control is no longer load.

Code:

private void Page_Load(object sender, System.EventArgs e)
{
if( Page.IsPostBack )
{
AddNewProject.Enabled = true;
AddNewComponent.Enabled = true;
DeleteComponent.Enabled = true;
RegisterUsers.Enabled = true;

private void DisplayControl( )
{
try
{
this.plcContent.Controls.Add( Page.LoadControl( "~/Administrators/" +
PageName + ".ascx" ) );
this.ShowSelection( PageName );
catch( Exception )
{
this.plcContent.Controls.Add( new System.Web.UI.LiteralControl(
"Invalid Selection!" ) );

private void ShowSelection( string sPage )
{
Button l_Button = (Button)this.FindControl( sPage );
l_Button.Enabled = false;

private void DeleteComponent_Click(object sender, System.EventArgs e)
{
PageName = "DeleteComponent";
DisplayControl( );

private void AddNewComponent_Click(object sender, System.EventArgs e)
{
PageName = "AddNewComponent";        
DisplayControl( );

private void AddNewProject_Click(object sender, System.EventArgs e)
{
PageName = "AddNewProject";
DisplayControl( );

private void RegisterUsers_Click(object sender, System.EventArgs e)
{
PageName = "RegisterUsers";          
DisplayControl( );
