Some bugs

[Francis]

Hey, here is some bugs I'm facing with my RadWindows and particularly the opener element.

1- When I minimize a RadWindow which is in fullscreen mode and click on its opener element, the window comes back in fullscreen but only wide-side, not height-side.

2- When I minimize a window and click its opener element, only the top bar of the window is visible. The only way I found to fix this is to put an animation to my RadWindowManager.

3- When my window is already shown and I click on its opener element again, the window does a quick refresh (flash), is it even possible to avoid that ?

and the last one even if I'm not sure if the opener element is reponsible for that...

4- Sometimes the opener element just won't show its window for some reasons.

Thanks in advance guys,
Francis

Hi Francis,

I will address the issues in the order you entered them:

1) The wrong height for the maximized window is a known issue under IE9 and it has been fixed in the latest release (Q1 2011 SP2).

2) When the RadWindow is minimized only its titlebar should be visible.Trying to open it again without closing it first is not a correct scenario as the opener code would try to set the required size, while the CSS class for the minimized window is still applied and allows for a smaller size, which will result in a conflict.

3) The way the opener element works is to attach a client-side handler to the said element and show the window through JavaScript, thus this cannot be avoided. You can work around that if you use your own JavaScript function (as explained below) and check if it is closed before opening it (by using the isClosed() method)

4) The OpenerElementID property should be used in simple scenarios and is not absolutely guaranteed to work in INaming containers, with AJAX callbacks and/or when some other custom logic can overwrite the handlers or dispose the objects (the RadWindow and/or the opener element)

The general suggestion I can give is to use a client-side event handler and an explicit JavaScript function to open the window, as you can perform some custom logic there, set the RadWindow properties accordingly, etc. For example:

<asp:Button ID="Button1" Text="Open Window" runat="server" OnClientClick="OpenWidnow(); return false;" />

function OpenWidnow()
{
    //custom logic here
    $find("<%=RadWindow1.ClientID %>").show();
}

All the best,

I recently moved a RadWindow out of a RadWindowManager and now I am getting a JavaScript error in the "get_defaultMinWidth" method of the Telerik JS code...

get_defaultMinWidth:function(){
if(!this._defaultMinWidth){var c=this._getHandlesWidth();

this._defaultMinWidth=c;

if(this._visibleTitlebar){var e=this._tableElement;

var g=this._getTitleElement();

var d=g.style.width;

if(g){g.style.width="1px";

}if(this._dockMode){this._contentElement.style.width="1px";

}e.style.width="1px";

var f=this._titleCell.offsetWidth;

g.style.width=d;

e.style.width="";

if(this._dockMode){this._contentElement.style.width="";

}this._defaultMinWidth+=f;

}}return this._defaultMinWidth;

}

It crashes on "this._contentElement.style.width="1px";" because the "this._contentElement" is null!

Here's my markup...

<telerik:RadWindow runat="server" ID="dlgPerson" ClientIDMode="Static"
        Behaviors="Close,Resize,Move"
        DestroyOnClose="True"
        IconUrl="/Content/Icons/User-blue_16x16.png"
        Modal="True"
        Title="Person"
        VisibleStatusbar="False"
        Height="350"
        Width="250">
        <ContentTemplate>
...

I have no idea why this is happening all the sudden when it WAS working just fine inside the RadWindowManager.  I moved it out because I really need to use a standard UpdatePanel.

I've noticed that I get this JS error anytime I specify the ContentTemplate.  If I take the Content Template out, the error stops.  But that doesn't help me since I need content!

Hello Time,

Please remove the ClientIDMode="Static" setting and see if this helps. Complex container controls (like RadWindow) do not support this setting and MS also advise that it should not be set for containers (i.e. INamingContainer).

Thank you, that works.  I never would have thought that would be an issue.
