The following code example provides a PropertyValueUIItem object for any properties of the component named HorizontalMargin or VerticalMargin. The PropertyValueUIItem for these properties provides an image, a ToolTip, and an event handler that displays a message box when the image for the property is clicked. This code example is part of a larger example provided for the IPropertyValueUIService interface.
' PropertyValueUIHandler delegate that provides PropertyValueUIItem ' objects to any properties named HorizontalMargin or VerticalMargin. Private Sub marginPropertyValueUIHandler(ByVal context As System.ComponentModel.ITypeDescriptorContext, ByVal propDesc As System.ComponentModel.PropertyDescriptor, ByVal itemList As ArrayList) ' A PropertyValueUIHandler added to the IPropertyValueUIService ' is queried once for each property of a component and passed ' a PropertyDescriptor that represents the characteristics of ' the property when the Properties window is set to a new ' component. A PropertyValueUIHandler can determine whether ' to add a PropertyValueUIItem for the object to its ValueUIItem ' list depending on the values of the PropertyDescriptor. If propDesc.DisplayName.Equals("HorizontalMargin") Then Dim img As Image = DeserializeFromBase64Text(imageBlob1) itemList.Add(New PropertyValueUIItem(img, New PropertyValueUIItemInvokeHandler(AddressOf Me.marginInvoke), "Test ToolTip")) End If If propDesc.DisplayName.Equals("VerticalMargin") Then Dim img As Image = DeserializeFromBase64Text(imageBlob1) img.RotateFlip(RotateFlipType.Rotate90FlipNone) itemList.Add(New PropertyValueUIItem(img, New PropertyValueUIItemInvokeHandler(AddressOf Me.marginInvoke), "Test ToolTip")) End If End Sub
