Editing arrays in PropertyGrid

Is there any way to prevent a PropertyGrid from allowing the user to expand
the elements of an array? For properties that are of type ArrayList or
CollectionBase a PropertyGrid only allows the items to be edited in the
Collection Editor (by clicking the button with the ellipses). But, for
properties of type Array a PropertyGrid also allows array elements to be
edited directly by expanding the array within the PropertyGrid. The problem
is that (as far as I know) no events are raised when the value of an element
is changed directly in the PropertyGrid, but I need to know whenever an array
(or any of its elements) change so that I can update my application.

Thanks for any help.

Hi Lance,

Thanks for your posting!

The expanded behavior for Array type property is achieved through
ExpandableObjec tConverter class, and Array class is defaultly assiciated
with this class, so it will default expand itself in PropertyGrid.

Based on my understanding, you want to be notified when a child item of the
array is modified in PropertyGrid.

Currently, we may use propertygrid's PropertyValueCh anged event to
intercept the property modify operation. Hope this helps.

I have a very basic program, but for some reason I can't get it to behave properly. What I want is a basic form with a TabControl that fills the entire form.

I'm populating my property grid with an object that has some ints, strings and arrays of other objects. If I make a change to the ints or string, the property grid will keep them but if I make chages to the objects in the array, the next time I click around the GUI, the propertygrid reverts the values in the array back to original.

I have a PropertyGrid question. My task is to replace a legacy dialog box presentation with a modern one.

Hi there I have a Propertygrid in a C# project that has a number of IP addresses displayed. What I would like to do is to a) Edit them in-place as the 4 octets, ie edit them as xxx.xxx.xxx.xxx possibly using the IPControl, and b) validate them on losing focus in the editing area. I've done a lot of googling, and frankly, I am now confused!

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
