We also attempt to show a legitimate use of Accessor Properties, which improve the robustness of code. Jeff - Thursday, August 27, 2009 1:33:31 PM Ok, so I got your example working. Otherwise the Xaml Parser doesn't find the attached DesignTimeData property.

Lets start again, taking what we've learned so far. My binding expression within the attached property assignment should have been written as follows. The app compiles fine, but the Visual Studio Designer throws error after error at me. Imported from legacy forums.

As seen in the example, trying to write into the non-writable property doesn't change it but doesn't throw an error either. And even when you can rely on it, there's really no good reason to do so. They share the following required keys: configurable true if and only if the type of this property descriptor may be changed and if the property may be deleted from the corresponding http://www.infragistics.com/community/forums/t/3915.aspx I'm searching a workaround for this problem.

In order to ensure these defaults are preserved you might freeze the Object.prototype upfront, specify all options explicitly, or point to null as __proto__ property. // using __proto__ var obj = Can be 031 * used as a convenience base class for more sophisticated implementations.

The getter-setter accessor functions are hidden from the syntax by indirectly accessing the name value through the get and set fields of the Accessor Property Descriptor. The example below is not an ideal way to define an object and it's properties, however through the following contrived method, I hope to highlight various rules around property creation and

I can't get this to work.The current error I'm getting is "Value 'igRibbon:ButtonTool.SizingMode' cannot be assigned to property 'Property'. http://electrictricycle.net/cannot-be/cannot-be-written-to-the-property-ssis.html Jeff - Thursday, August 27, 2009 1:29:07 PM Oh, forget my last comment.

Up until now, we've used literal object notation, which defaults writable, enumerable and configurable to true. The function return will be used as the value of property. We now have an image object that will always have name and size properties. have a peek here Thank you in advance for help Imported from legacy forums.

Rows in green identify attributes used to categorise a descriptor. Sounds like this may be one of those cases, only with the Visual Studio Designer instead of Blend.

Properties created using object creation methods have boolean defaults set to false Properties created using an alternative method have boolean defaults set to true Further Reading Define property ECMAScript 5 Objects Maybe a possible method would be to have an alternate style which is applied only at design time and sets various properties to design time defaults. What you can do is simply handle the EditLeft or the ValueChanged event on the cell, andcall EndEdit() on the row. http://electrictricycle.net/cannot-be/cannot-be-indexed-because-it-has-no-default-property-vb-net.html An accessor descriptor is a property described by a getter-setter pair of functions.

Not the answer you're looking for? writable true if and only if the value associated with the property may be changed with an assignment operator.
