Can't send ImageUrl to radWindow

[mromani]

Hi, Im using 'Returning Values from a Dialog Demo' in my project, but i can't get asp:Image.ImageUrl and send it to radWindow.  That work fine with textarea, but not with Images. I think that problem its in javascript. There are same way to send this value?

	function showDialog()
	{
	//Force reload in order to guarantee that the onload event handler of the dialog which configures it executes on every show.
	var oWnd = window.radopen(null, "DialogWindow");
	oWnd.setUrl(oWnd.get_navigateUrl());
	}
	//Called when a window is being shown. Good for setting an argument to the window
	function OnClientshow(radWindow)
	{
	//Get current content of textarea
	var oText = document.getElementById("ImageFoto1");
	//Create a new Object to be used as an argument to the radWindow
	var arg = new Object();
	//Using an Object as a argument is convenient as it allows setting many properties.
	arg.ImageUrl = oText.ImageUrl;  // This don't work
	//Set the argument object to the radWindow
	//radWindow.Argument = arg;
	radWindow.Argument = arg;
	}

Thanks for your support.

Hi mromani,

The described problem is not directly related to RadWindow but to general JavaScript knowledge. You cannot take an asp:image' image url by using such syntax - this property is undefined and that is why you cannot extract it.

The correct way to extract the image's url is the following one:

var imageUrl = document.getElementById('ImageFoto1').attributes["src"].value;
