Controls Property Not Set
I have created a custom control and one of the properties of it is a Rollover Image.
Here is the property
VB Code:
<DefaultValue(""), _
Description("This will set the rollover image of the control."), _
Editor(GetType(System.Web.UI.Design.ImageUrlEditor), _
GetType(System.Drawing.Design.UITypeEditor))> _
Public Property RolloverImage() As String
Get
mstrRolloverImage = ViewState("RolloverImage").ToString
If mstrRolloverImage.Length = 0 Then
Return mstrRolloverImage.Empty
Else
Return mstrRolloverImage
End If
End Get
Set(ByVal Value As String)
mstrRolloverImage = Value
ViewState("RolloverImage") = mstrRolloverImage
End Set
End Property
The problem occurs when I compile the control, add it to my toolbox, then drop it on my page...The Rollover Image property displays "Object reference not set to an instance of an object"...but I'm not sure why???
Anyone have any ideas how to fix this?
