If you have multiple screens, you can open a second DashBoard window (Window->New Window) and drag from one to the other that way.
If you don't, here is a way you can add scroll bars to ViewControl (by embedding the whole ViewControl screen into a CustomPanel with scrolling enabled):
<abs contexttype="opengear" style="">
<meta>
<params>
<param access="1" maxlength="0" name="Carbonite Node ID" oid="Carbonite_Node_ID" type="STRING" value="Carbonite 00:0F:9B:02:26:0D" widget="default"/>
</params>
</meta>
<editor bottom="5" left="5" objectid="%value['Carbonite_Node_ID'][0]%<br>Slot 0<br>Carbonite:view_control" right="5" scroll="true" top="100" widgetroot="true"/>
<label height="58" left="17" name="Node ID:" style="txt-align:east" top="22" width="163"/>
<param expand="true" height="57" left="184" oid="Carbonite_Node_ID" top="22" width="343">
<task tasktype="ogscript">ogscript.reload(null);</task>
</param>
<label height="95" left="532" name="<html>Right-click on the root node of Carbonite in the tree and select "View Frame Information". Copy the value of "node-id" here with CTRL+C and CTRL+V</html>" right="10" style="txt-align:west;" top="4"/>
</abs>
