Customizing Web Parts - Hiding property in edit mode?

Question

Update:

private string _catalogIconImageUrl = "http://hostname/images/favicon.ico";

 [WebBrowsableAttribute(false),
    Category("HIDDEN"),
    Personalizable(PersonalizationScope.User),
    WebDisplayName("Catalog Icon Image url"),
    WebDescription("Something")]
    public string CatalogIconImageUrl
    {
        get
        {
            return _catalogIconImageUrl;
        }
        set
        {
            _catalogIconImageUrl = value;
        }
    }

with the above code, it does not show the image and also when i click on edit the webpart i still able to see the catalogIconImageUrl prop in edit mode

Update end

I've declared the property CatalogIconImageURL in the .Webpart file as follows:-

</property>    
<property name="CatalogIconImageUrl" type="string">images/company/companylogo.jpg</property>    //sample path...
</properties>

if I click on the Advanced Web Part Gallery as shown below in the screen shot, i able to see that property in editable so my question is, is there a way i can hide this property when user edit the web part? "Catalog Icon Image URL"

Answer 1

The attribute should be WebBrowsable(false) not WebBrowsableAttribute(false) http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.webparts.webbrowsableattribute(v=VS.90).aspx

Answer 2

So is this a custom webpart that you coded? If so, you can change the property attributes in the code (not .webpart file):

   [WebBrowsableAttribute(false),
    Category("HIDDEN"),
    Personalizable(PersonalizationScope.User),
    WebDisplayName("Catalog Icon Image url"),
    WebDescription("Something")]
    public string CatalogIconImageUrl
    {
        get
        {
            return _catalogIconImageUrl;
        }
        set
        {
            _catalogIconImageUrl = value;
        }
    }

The one that will hide it when they click edit is the WebBrowseableAttribute(false), the other code is there just to help you with context.
