Hi All,

Can anyone help me to solve the issue?I dont know anything about Java. Silverlight issues pushing me to go with Javascript API. Without help I cannot move.

I added the Dynamic map through javascript API successfully. I would like to write all other code in vb.net. For that I am trying the code behind like below

Imports ESRI.ArcGIS.Client

Partial Class Default2

Inherits System.Web.UI.Page

Protected Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click

Dim displayExtent As New ESRI.ArcGIS.Client.Geometry.Envelope(23, 34, 33, 44)

DynamicMapServiceLayer.ZoomTo(displayExtent)

End Sub

End Class

Here I am getting error like below. How can I solve this?
