To integrate your aspx page in the eBiss Web Page you have to implement eBiss.Api.IWebPlugin and we recommand to inherit from class eBiss.WebPlugin.Sample.WebPluginBasePage instead of Page.

In your Page_Load you call base.OnPageLoad() to check and initilize the EBissSession.

[DisplayName("Name Of Sidemenu Subpoint")] //This Attribut will be the name of the sidemenu subpoint.
public partial class SamplePage: WebPluginBasePage, IWebPlugin
{
   //Implement interface member
 
    public WebPageKind Kind
    {
        get { return WebPageKind.RootPage; }
    }
 
    //1. if DisplayName is not set, groupname will be used. 
    //2. Identifier for the pages. One Group is able to have more than one page
    public string GroupName 
    {
        get { return "Name for Sidemenu Group"; }
    }
 
    //Name of the page. In this Example: Sidemenu Name: MyPluginPage, Pagename: MyPage
    public string PageName 
    {
        get { return "MyPage"; }
    }
 
    //Uri for the .aspx site. Usually the same as the classname
    public string Uri 
    {
        get { return "PlugIns/MyPluginPage.aspx"; }
    }
 
    protected void Page_Load(object sender, EventArgs e)
    {
       base.OnPageLoad();
       ...
    }
 
}

Using the property EBissSession you can search on eBiss, e.g. for documents:

foreach (IDocument doc in EBissSession.DataApplication.Find("eBiss.Data.Document", $"DocNumber.StartsWith(\"{value}\")"))
{
   Data.MessageItem msgItem = new Data.MessageItem(doc);
   source.Add(msgItem);
}

Use RedirectToErrorPage() for error handling:

Code-Beispiel2: Exception Handling.

// don't catch redirect exception!
try
{
    if (!IsPostBack)
    {
        ...
    }
}
catch (Exception ex)
{
    RedirectToErrorPage(ex);
}

If you don't use the Build events for copy you should copy the ./Deploy/ folder with sub folders to the eBiss path.
