Hiding a row in a PropertyGrid

[Guest]

Is it possible to hide a row within a PropertyGrid based upon the boolean
value of another row within the PropertyGrid? I am using VS2005 with .NET
Frameworks 2.0.

Hello SteveT,

Hi Steve,

This is not a trivial task. PropertyGrid exposes no interfaces to
manipulate its UI by removing/adding rows. Normally, PropertyGrid will use
Reflection to query the type/value on the SelectedObject and display one
property for a row. There is no easy way to tell PropertyGrid not to
display any row or add one row. PropertyGrid is not designed with this
function.

If you really want to achieve this task, one workaround is hooking into the
Reflection process of PropertyGrid during querying the object types/values.
Before PropertyGrid queries the properties, it will first query if the
object implement ICustomTypeDescriptor interface. So we can use this
interface as a hook to dynamically add/remove properties.
The codeproject article below demonstrates this technology:
"Add (Remove) Items to (from) PropertyGrid at Runtime"
http://www.codeproject.com/cs/miscctrl/Dynamic_Propertygrid.asp

Note: this technology needs the modification to the selected object instead
of the PropertyGrid class.

Hope this helps.

Best regards,
Jeffrey Tan

Actually - I seem to recall that you can do this by adding a custom
property-tab and simply tweaking the PropertyDescriptorCollection;
various examples on the net... removing is simpler... to add you need
to create your own PropertyDescriptor. Plenty of examples of that
also.
