Remembering position of DragOverlayExtender with Profile

You can get Atlas to store the last known position of your floating panel in the profile.

Three things you need to do to get this to work.

ProfileScriptService

In the page with the DragOverlayExtender you'll need to add a atlas:ProfileScriptService control (this is responsible for communicating with the profile back on the server) :

<atlas:ProfileScriptService AutoSave="true" ID="profileService" runat="server" />

DragOverlayExtender

You need to set the property name to store the position in, in this example my property name is PopupPosition

<atlas:DragOverlayExtender ID="EntryDetailDragExtender" runat="server">
    <atlas:DragOverlayProperties 
                TargetControlID="EntryDetailPanelContainer" 
                ProfileProperty="PopupPosition"
                Enabled="true" />
</atlas:DragOverlayExtender>

Web.Config entries

This had me baffled for a while, I knew that I had to add the property (PopupPosition) to my Profile/Properties in the system.web section:

<system.web>
    ....
    <profile automaticSaveEnabled="true" enabled="true">
        <properties>
            <add allowAnonymous="true" name="PopupPosition"/>
        </properties> 
    </profile> 
    ....
<system.web>

What I didn't realise that I needed to add another section to the microsoft.web section. See below for example:

<microsoft.web>
    ...
    <profileService enabled="true" 
                    setProperties="PopupPosition" 
                    getProperties="PopupPosition" />
    ...    
</microsoft.web>

Note: You can specify more than one property in the profileService element, simply seperate them with a ;

Alternatively, you could specify * and it will have access to all properties.
