I am trying to make dialog to show near the anchor using AnchorElementID and ShowDirection parameters in custom web control but it still appears in the center

this is control code

<%@ Control Language="c#" AutoEventWireup="false" Codebehind="ContentDialogHelpControl.ascx.cs" Inherits="tripapp.RU.GUI.ContentDialogHelpControl" TargetSchema="http://schemas.microsoft.com/intellisense/ie5"%>
<%@ Register TagPrefix="eo" NameSpace="EO.Web" Assembly="EO.Web" %>
<eo:Dialog runat="server" id="hD" ControlSkinID="None" Width="300px" Height="200px" HeaderHtml="Dialog Header"
BorderStyle="Solid" CloseButtonUrl="00070101" MinimizeButtonUrl="00070102"
BorderWidth="1px" ShadowColor="LightGray" BorderColor="#335C88" RestoreButtonUrl="00070103"
ShadowDepth="3" ResizeImageUrl="00020014">
<HeaderStyleActive CssText="padding-right: 4px; padding-left: 4px; font-size: 11px; background-image: url(00070104); padding-bottom: 3px; padding-top: 3px; font-family: tahoma"></HeaderStyleActive>
<ContentStyleActive CssText="border-top: #335c88 1px solid; background-color: #e5f1fd"></ContentStyleActive>
</eo:Dialog>
<a id="hl1" runat=server>Show Dialog</a>


this is c# code

namespace tripapp.RU.GUI
{
using System;
using System.Data;
using System.Drawing;
using System.Web;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;

/// <summary>
/// Summary description for ContentDialogHelpControl.
/// </summary>
public abstract class ContentDialogHelpControl : System.Web.UI.UserControl
{
protected EO.Web.Dialog hD;
protected System.Web.UI.HtmlControls.HtmlAnchor hl1;
protected System.Web.UI.HtmlControls.HtmlGenericControl div1;

private void Page_Load(object sender, System.EventArgs e)
{
// Put user code to initialize the page here
string itemid="helpDialog_" + place + "_" + header;
hl1.ID="helpLink_" + place + "_" + header;
//div1.ID="helpDiv_" + place + "_" + header;
hl1.HRef="javascript:eo_GetObject('" + itemid + "').show(true);";
hD.ID=itemid;
//hD.ConfineElementID="helpDiv_" + place + "_" + header;
//hD.ConfineElementID="div1";
hD.AnchorElementID="helpLink_" + place + "_" + header;
hD.ShowDirection=EO.Web.ExpandDirection.Auto;

hD.HeaderHtml=header;
hD.ContentHtml=itemid;
}

protected string place="";
protected string header="";

public string Place
{
set
{
place=value;
}
}

public string Header
{
set
{
header=value;
}
}

#region Web Form Designer generated code
override protected void OnInit(EventArgs e)
{
//
// CODEGEN: This call is required by the ASP.NET Web Form Designer.
//
InitializeComponent();
base.OnInit(e);
}

/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
/// </summary>
private void InitializeComponent()
{
this.Load += new System.EventHandler(this.Page_Load);
}
#endregion
}
}

Hi,

That occurs when the dialog can not find the AnchorElementID. Try call document.getElementById(your_anchor_element_id) and see if you get an object or null. If it returns null, then the ID is wrong.

Thanks

Found solution by myself
easy and effisient

//hD.AnchorElementID="helpLink_" + place + "_" + header;

hD.AnchorElementID=this.ClientID+"_helpLink_" + place + "_" + header;

One word, I changed it to server control identifier generated by ASP.NET
