PropertyGridItem

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello.
Im' developping an application in VB.NET using PropertyGrid ActiveX (9.81).It is possible to customize the PropertyGridItem.Value property and manage the value with a sort of TypeConverter ?.
(The DirectoryItem sample is simple becouse the returned data is String   eg. "C:\" and all works fine.)
My idea is to assing a value that is a ArrayList (or another type of VB object).
Only a Dream?.
Thanks for the attention and sorry for my spaghetti english.(ITA)

	Value is an Object property so you should be able to store any type you want. Maybe you can use the AfterEdit event or ValueChanged events to manually manuave the value when it is changed. The AfterEdit event occurs after an edit operation, but before the value has been changed. AfterEdit allows you to modify the new value before it is applied or you can completely cancel the operation.

	Private Sub wndPropertyGrid_InplaceButtonDown(ByVal sender As Object, ByVal e As AxXtremePropertyGrid._DPropertyGridEvents_InplaceButtonDownE vent) Handles wndPropertyGrid.InplaceButtonDown UIDebug.Write("Inplace button down. Item.Caption = " + e.item.Caption) Dim x As New UIConverterSpecifiche If x.ShowDialog() = DialogResult.OK Then e.item.Value = x.Value Debug.Write(x.Value.GetType.ToString & " " & e.item.Value.GetType.ToString) End If End Sub Sorry. SuperMario. Code is very simple... My Dialog return a System.ArrayList value type. After assign the returned value at e arguments e.item.Value = x.Value the result is ... typeof variable x is System.ArrayList while e.Item.Value type is System.String. WHY? n.b. System.String is the same type which i use for add the PropertyGridItem to the grid. Dim ItemDirectory As PropertyGridItem = Category.AddChildItem(PropertyItemType.PropertyItemString, "TEST", value) ItemDirectory.Flags = PropertyItemFlags.ItemHasExpandButton A possible BUG ? or how can i ovverride the problem? Thanks Super.
