Is it possible to open an SharePoint app as Modal dialog from a Custom Action

Question

I want to create a site action menu item Custom Action which opens a Sharepoint 15 app (default.aspx) as modal dialog. is it possible? thanks.

Answer 1

There is out of the box support for opening a dialog from custom action. Add following attributes to the CustomAction XML node --

• HostWebDialog : Set it to true if you want to open a dialog
• HostWebDialogWidth: Width of the dialog
• HostWebDialogHeight: Height of the dialog

For more information go to my blog here. Hope this would help you.

Answer 2

Open Elements.xml file of custom action and add following attributes in tag.

        HostWebDialog="TRUE"
        HostWebDialogWidth="600"
        HostWebDialogHeight="400

and then in your aspx page add

<WebPartPages:AllowFraming ID="AllowFraming" runat="server"/>

Answer 3

You should be able to do it through the following way:

1) Create a SharePoint page: placeHolder.aspx

2) Create an AppPart/Client WebPart for your App and place it on placeHolder.aspx

3) Open placeHolder.aspx inside the Modal Dialog

4) Open the Modal Dialog from a custom action.
