GUI Extension | How to Customize views for GUI extension

Question

I am trying to enable my control for DashboardView and ComponentView. In DashboardView view I can enable the control on selection of component which is working fine BUT if i open the component in ComponentView the control is not getting enabled. If some have the solution? Here is the code

Extensions.HW.prototype.isAvailable = function HW$isAvailable(selection, pipeline)
{
 var items = selection.getItems();
  var item = $models.getItem(selection.getItem(0));

if (items.length >= 1 &&  item.getItemType() == $const.ItemType.COMPONENT ) { 
    return true;
    }
    else {
        return false;
    }
};

Extensions.HW.prototype.isEnabled = function HW$isEnabled(selection, pipeline) {
    var items = selection.getItems();
     var item = $models.getItem(selection.getItem(0));
    if (items.length >= 1 && item.getItemType() == $const.ItemType.COMPONENT ) {        
            return true;
    }
    else {
        return false;
    }
};

I am using two views in configuration as

      <cfg:dependency>HelloWorldRibbon.Commands</cfg:dependency>
      </ext:dependencies>

      <ext:apply>
        <ext:view name="DashboardView">
          <ext:control id="DashboardToolbar" />
            </ext:view>
         <ext:view name="ComponentView">
          <ext:control id="ItemToolbar" />

        </ext:view>

      </ext:apply>
    </ext:extension>

Here is the screenshot on which control is disabled

I want to enable this control while component is opened.

Your logic for isEnabled and isAvailable is triggered around the selection variable, and in your case checking to see if the item selected is a component and that the number of items selected is at least one. This works in your DashboardView when you select a component because your selection now has a length of one, and the item.getItemType() is a component.

However in your ComponentView, you don't have anything selected. You'll want to adapt your logic here to remain the same for DashboardView, but to always show for ComponentView.

You can modify your check to do something like:

if ($display.getView().getId() === "ComponentView") {
    return true;
}
...
can be considered a DashboardView at this point, put your existing logic here from your example to check the selection variable
...

Hope that helps! You should now have your extension always showing in the Component View (assuming that's what was desired), and only enabled in Dashboard view if you have selected a component item.
