Why is the Folder Browser button disabled on my custom activity property

I have a property in my custom activity that accepts a Laserfiche folder path. In the Activity Proxy Generator I selected the "Support browsing to a Laserfiche folder" option for this property. The attribute is present in the proxy class file:

[DisplayNameAttribute("Destination Path")]
[SortIndexAttribute(11)]
[TextboxWithFolderBrowserAttribute(true, CustomTokenType.DefaultExcludedFromMenus, CustomTokenType.None, 1, 32767)]
public string DestinationPath
{
  get
  {
    return this.destinationPath;
  }
  set
  {
    if (this.destinationPath != value)
      {
        string old = this.destinationPath;
        this.destinationPath = value;
        this.OnPropertyChanged(DestinationPathPropertyName, old, value);
      }
   }
}

But the button is disabled:

Any suggestions? Thanks!

TextboxWithFolderBrowserAttribute makes the property use the BrowseForFolderEditor property editor, which has an IsEnabled function that determines the state of that button. The IsEnabled function returns false under two conditions:
1) if the activity does not implement the IConnectionProfile interface
2) if the activity's ConnectionProfile property is null

Without seeing the rest of your class and how it's being used in the workflow, I can only guess that either:
1) Your custom activity proxy isn't derived from one of the classes that implements the IConnectionProfile interface (CustomProfileActivityProxy, CustomSingleEntryActivityProxy, CustomDoubleEntryActivityProxy, or CustomCompositeProfileActivityProxy)

Note that this is typically determined by the Include a connection to Laserfiche option in Step 3 of the Activity Proxy Generator (Documentation).

2) You haven't selected a connection profile (the Connection Profile property) for your activity in the workflow yet

Thank you, I changed the class that the custom activity proxy is derived from and it's working now.
