Event that fires when user clicks on the "New" button of an ASP.Net DetailsView

Question

In an ASP.Net VB.Net code-behind file, can you tell me what event fires that I can use to trap when the user clicks on the "New" button of a DetailsView at the time the DetailsView shows blank items such as DropDownLists, TextBoxes etc?

I need use this event handler to pre-select a value in a DropDownList obtained from a variable.

Try the ItemCommand event. This is how to use it. I only know C# , but I think you get the hang of it.

Code behind:

protected void DetailsView_ItemCommand(object sender, DetailsViewCommandEventArgs e)
{
    if (e.CommandName == "New")
    {
        // Your code here
    }
}

Markup:

<asp:DetailsView ID="DetailsView" runat="server" OnItemCommand="DetailsView_ItemCommand" ...
