Hi
I'm using the DragOverlayExtender to create a draggable UI (like live.com).
How can I define some fix drop-zones? So dragged objects should only drop there.
Tank you.
Hi,I've just postedan article on my blog about drag&drop in Atlas, that includes an example of a draggable UI. Hope it helps.
Thx - this seems to be exactly what I was looking for!
But how can I add a control-section at runtime?
<control id="content1">
<behaviors>
<draggableListItem handle="content1Handle"
dataType="HTML" />
</behaviors>
</control>
I found that this works with
IScriptControl ctrl =
ScriptManager.GetCurrent(this).RegisterControl(myControl);
Then on ctrl there is a Method called RegisterBehaviour, but how can I use this. The method needs an IScriptBehavior-Implementation - so how can I use the draggableListItem-Behavior for this?
Hi,
Following the Atlas philosophy, the suggested approach (server-centric) would be that of creatingextenders for drop zones and draggable panels. Basically you have to derive a class fromExtenderControl
and a class fromTargetControlProperties
. Then, override theRenderScript()
method of theExtenderControl
class to render the Atlas markup.
Checkthis blog entry byNikhil Kotari orthis one from my Atlas blog, for some info about extenders.
Hi,
well, what I wrote above is not 100% correct, since anextender is supposed to extend an existing ASP.NET control or maybe acustom ASP.NET control. What you could do is build an Atlas-enabledserver control, rendering both the HTML and the Atlas markup.
Checkthis blog entry and look at the section "Support for Atlas-Enabled Server Controls" for some info.
Hey
So your second post is the way I tried... but I have still the problem that I mentioned. The number of controls that are draggable is not known at designtime, so I'd like to insert the DnD-behaviors for the different controls at runtime.
The follow method seems to be the one - but I don't know how to implement:
Microsoft.Web.Script.IScriptControl c =
ScriptManager.GetCurrent(this).RegisterControl(myControl);
c.RegisterBehavior(xxx);
So the 3x should be an IScriptBehavior-Implementation. In the declarative Way, I used
<control id="CVPart">
<behaviors>
<draggableListItem handle="CVPartTitle" dataType="HTML" />
</behaviors>
</control
So what do I have to do, to register this behavior (draggableListItem) at runtime.
OK... I found a quite simple solution... :-)
I've just created a new class that implements IScriptBehavior (and IScriptObject).
In the RenderScript-Method I just create the <draggableListItemhandle="myControl" type="HTML" /> with the ScriptTextWriter...
3 Lines of code... one day is over :-D
Thank you!
Hello! Could you please send me an example of your code?
Just to not waste the whole day for 3 lines of code ;)
Thank you!
