Examples

The following example is part of the code-behind file for the Insert.aspx page template. The MetaTable instance is initialized in the Page_Load method. The title for the page is set to the table DisplayName property.

public partial class Insert : System.Web.UI.Page {  
    protected MetaTable table;     
  
    protected void Page_Load(object sender, EventArgs e) {  
        table = DetailsDataSource.GetTable();  
        Title = table.DisplayName;  
    }  
}  
Partial Class Insert  
    Inherits System.Web.UI.Page  
  
    Protected table As MetaTable      
  
    Protected Sub Page_Load(ByVal sender As Object, _  
            ByVal e As EventArgs)  
        table = DetailsDataSource.GetTable  
        Title = table.DisplayName
