Category Item related issue

Hi Anurodh,

Currently, there is no property on the "data layer" objects (such as PropertyGridCategoryItem), that allows you to specify whether they are expanded. We may add this type of feature in the future.

What you can do is apply an implicit style to the PropertyGridDataAccessorItem type to expand or collapse certain categories. You would need use one or more triggers based on the DataAccessorType being Category, and the DisplayName equals the category in question. Then you would set the IsExpanded property appropriately.

Additionally, you can disable the automatic expansion of all categories by setting PropertyGrid.AreCategoriesAutoExpanded to false.

Hello,
Is it possible to have a small code example to download?
Thank you :)

Hi Nicolas,

This post shows some code examples.

The first example assumes you have a custom IValueConverter that will take the DisplayName of the category and return either true (expanded) or false (collapsed). The second example actually binds the expanded state to a custom ICategoryDataAccessor. The first example is more applicable here, though.

After posting my message earlier, I kept looking and I found this sample and manage to customize the expanded state of the categories.
Thanks :)
