Detect when FileNameEditoris shown

[ljlevend]

I have a file path (i.e., String) property that uses a
System.Windows.Forms.Design.FileNameEditor as its
System.ComponentModel.Editor. This property is exposed by a PropertyGrid.
What I need to do is to detect when the Open File dialog is shown (when the
user clicks the ellipsis for that property) and when the dialog is closed so
that I can suspend certain events while the dialog is being displayed. Is
this possible?

Hi

I think you may need to inherits the FileNameEditor class and override the
FileNameEditor.EditValue Method.
Because when we click in the propertygrid to modify the property, we will
invoke the File Dialog in the EditValue method of FileNameEditor class.

You may try to get the open and close as the form similar with below.
e.g. pcode
FileNameEditor.EditValue
{
BeginOpenDialog;
base.EditValue(...);
EndOpenDialog;
}

Hope this helps!
