WebPart exportMode in UserControl. Inherit from 2 classes4/10/2006 10:06:49 AM

0/0

Hello.

I have a WebPartBase.cs class that inherit from UserControl and IWebPart.

namespace

 grupo.WebParts{

         public class WebPartBase : UserControl, IWebPart {

         .........

This class is used in multiple UserControls, for instance:

         public

 partial class webparts_news : grupo.WebParts.WebPartBase {

         ..........

I like to add ExportMode=All in my WebPartBase class, but IWebPart interface doesn?t have this property. I would like inheriting from 2 classes (UserControl and WebPart) to do it, but It's impossible in .NET 2.0.

Any posibilities?

Two options:

1. Set the property on the GenericWebPart wrapping the UserControl:
GenericWebPart gwp = WebPartManager.GetCurrentWebPartManager(Page).GetGenericWebPart(this);
gwp.ExportMode = WebPartExportMode.All;

2. Set the "ExportMode" expando via the IAttributeAccessor interface.  The GenericWebPart will pull the value from the IAttributeAccessor and set its ExportMode property:
((IAttributeAccessor)this).SetAttribute("ExportMode", "All");

3rd option,

You have to web.config see I have enableExport set to true.  At run time you can check the allow export in the behavior editor.  Is the next question the importCatalogpart?  Cause the importcatalogpart imports webparts that have been exported.

<

webParts enableExport="true">

<

personalization >

<

authorization>

<

allow users="DWS400" verbs="enterSharedScope, modifyState"/>

</

authorization>

</

personalization>

</

webParts>

 

 You have to use the behavior editor to enable export and web.config

Thanks Mike.

Your reply helped me. I update the code, this is the result:

UserControlBase class:

...............

WebPartCollection colecionWebParts = WebPartManager.GetCurrentWebPartManager(Page).WebParts;

foreach (WebPart wp in colecionWebParts){

         wp.ExportMode = WebPartExportMode.All;

}

..............
