//// My Custom Image Class /////
Public Class imageClass Inherits System.Web.UI.WebControls.Image
Public imageLabel As String = ""
End Class
/////// Default.aspx.
vb ////////
Protected Overrides Sub OnInit(ByVal e As EventArgs)
Dim picture As imageClass = New imageClass
pholder.Controls.Add(picture)
/// THIS SHOULD CHANGE VIA JAVASCRIPT///
picture.imageLabel = "LabelOne"
picture.Attributes.Add("onclick","javascript
:click 1('" & picture.ClientID & "')")
End Sub
Protected Sub Submit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Submit.Click
Dim NewImage As imageClass = New imageClass
For Each con As Control In pholder.Controls
If TypeOf con Is imageClass Then
/// SHOW OLD VALUE DECLARE IN ASPX.VB ///
MsgBox(CType(con, imageClass).imageLabel)
end if
Next
End Sub
/////// Default.aspx ////////
<script type="text/javascript" >
function click1(id1){document.getElementById(id1).setAttrib ute("imageLabel","Click");}
</script>
<html>
<body>
<form id="form1" runat="server">
