I am looking for a place to initialize some variables in an aspnet Wizard.

I want this stuff to be called 1 time.  After the constructor has been set up.

I've tried Wizard1_PreRender  and Wizard1_Init,  in both cases they are called with each Wizard step. 

Where is the correct place for my initialization?

TIA

Hi,

You can locate the intializing code in either Wizard_PreRender and Wizard_Init event.

The key point in this case is page's postback. As we know, when next step is called in Wizard control, the page will postback and in this process, the page will load Wizard again, and call the event like Wizard's Init or Wizard's PreRender.

So, to solve this issue, we need to have a judgement to see if the page has been posted back in these event handler.

I suggest you trying with the example below, which put your intializing code into If(!Page.IsPostBack) statement block.

protected void Wizard1_PreRender(object sender, EventArgs e)
{
    if (!Page.IsPostBack)
    {
        //your initializing code
    }
}

In addition, I would also like to suggest you having a read at this artilce talking about ASP.NET page life cycle: http://msdn.microsoft.com/en-us/library/ms178472.aspx. 

And this one about Page.IsPostBack property: http://msdn.microsoft.com/en-us/library/system.web.ui.page.ispostback.aspx.

I believe after reading these two articles, you can learn much related to this issue.
