On an aspx page i have included the control eo.Dialog for messages.

Via javascript I call the control with the command eo_GetObject("Dialog01").

I get the error message "TypeError: Cannot read properties of null (reading: 'setCaption')

If I include the control via a UserControl (*.ascx) the call works without problems.

Code: HTML/ASPX
[size=4]<%@ Page Language="C#" EnableViewState="false" CodeFile="datenArchiv.aspx.cs" AutoEventWireup="true" Inherits="datenArchiv" %>
<%@ Register TagPrefix="eo" Assembly="EO.Web" Namespace="EO.Web" %>

				</ContentTemplate>

Code: JavaScript
[size=4]function imagebuttonEpressed() {

	try
	{

		divImage15Einblenden();

		showMsgBox('imagebuttonEpressed()', 'Export data?', 10);

		...



function showMsgBox(_nameOfFunction, _question, _index) {

	try
	{

		var oDialog=eo_GetObject("Dialog01");
		oDialog.setCaption(_nameOfFunction);

		...[/size]

Hi,

The root of the issue is the textarea element in your ContentTemplate. You need to change it from:

Code: HTML/ASPX
<textarea id="LDiaText" class="memoTCP2" style="...." />

To:

Code: HTML/ASPX
<textarea id="LDiaText" class="memoTCP2" style="....">
</textarea>


textarea element can not be self closed. Otherwise everything after the textarea will be considered contents of the textarea element.

Thanks!
