Hi,
if you add first the drag control and afterwards the selectfeature control,
then you can drag a feature without selecting and select a feature. Only
disadvantage is the moving cursor for selecting a feature.
var lyr = map.layers[1];
ctrlDragFeature = new OpenLayers.Control.DragFeature(lyr);
map.addControl(ctrlDragFeature);
ctrlDragFeature.activate();
ctrlSelectFeatures = new OpenLayers.Control.SelectFeature(
lyr,
{
clickout: true, toggle: false,
multiple: false, hover: false,
toggleKey: "ctrlKey", // ctrl key removes from selection
multipleKey: "shiftKey" // shift key adds to selection
}
)
map.addControl(ctrlSelectFeatures);
ctrlSelectFeatures.activate();

Betreff: Re: [OpenLayers-Users] Draggable and Selectable features on map
What I want is that you simply click the marker, hold the button down, drag
and drop.
Like this example:
http://code.google.com/apis/maps/documentation/javascript/v2/examples/marker
-drag.html
(ignore the balloon in this example)
As I understand it, if I use the ModifyFeature control I'll have to click it
first (click and release) to select the marker. Then do my click/drag/drop.
As in this example:
http://openlayers.org/dev/examples/modify-feature.html
In the openlayers example above, draw a point, then tick "modify feature /
allow dragging". You have to click to select, then you're allowed to
drag/drop.
Bit fiddly to explain - hope that's clear!

How can you drag something without first clicking and selecting? Your
request is not clear. Care to elaborate?
