I am having some trouble with radscriptblock when the parent control is hidden and shown again through an ajax postback.

JSTest.aspx.cs: http://pastebin.com/G4ZFB32z
JSTest.aspx: http://pastebin.com/YpQWidRC
MyControl.aspx.cs: http://pastebin.com/NfXrQGiL
MyControl.aspx: http://pastebin.com/DZkJeJzd

When I click "Hide", the panel and control inside it become hidden. When I click show, the control is shown, but I get the following javascript error: 
Uncaught TypeError: Cannot read property 'currentStyle' of undefined Telerik.Web.UI.WebResource.axd:6
Sys.UI.DomElement.getVisible Telerik.Web.UI.WebResource.axd:6
Sys.UI.DomElement.setVisible Telerik.Web.UI.WebResource.axd:6
Sys.UI.Control.set_visible Telerik.Web.UI.WebResource.axd:6

Hello Andrey,

Please try moving the checkUILoaded function declaration in the InstalledByCheckChanged function:

function InstalledByCheckChanged()
{
    var fromBox, toBox;
    var byUserRadioBtn, byConhtractorsComboBox;
 
    function checkUILoaded()
    {
        if (typeof (fromBox) == 'undefined' || fromBox == null)
        {
            fromBox = $find('<%= m_oByUsersSrcListBox.ClientID %>');
            toBox = $find('<%= m_oByUsersDestListBox.ClientID %>');
            byUserRadioBtn = $find("<%= m_oByUserRadioButton.ClientID %>");
            byConhtractorsComboBox = $find("<%= m_oByContractorComboBox.ClientID %>");
 
        }
        return typeof (fromBox) != 'undefined' && fromBox != null;
    }
    if (checkUILoaded())
    {
        if (byUserRadioBtn.get_checked())
        {
            fromBox.set_visible(true);
            toBox.set_visible(true);
            byConhtractorsComboBox.set_visible(false);
        } else
        {
            fromBox.set_visible(false);
            toBox.set_visible(false);
            byConhtractorsComboBox.set_visible(true);
        }
    }
}

I hope this helps.

All the best,
Martin
