Very Simple problem

Hi i don't know why the following doesn't work. I simply have a list of items in an array which i have bound to a dropdownlist.

Code:

<%@ Page Language="VB" ContentType="text/html" ResponseEncoding="iso-8859-1" %>
<script runat="server">
Sub Page_Load()
	If NOT ispostback then
		Dim ColorArray(4) as String
		ColorArray(0) = "Blue"
		ColorArray(1) = "Red"
		ColorArray(2) = "Green"
		ColorArray(3) = "Yellow"
		ColorArray(4) = "Orange"
		MyDropDownList.DataSource = ColorArray
		MyDropDownList.DataBind()
	End if
End Sub

Sub ColorSelected(Source as Object, E as EventArgs)
	Dim MyColorText as String
	MyColorText = MyDropDownList.SelectedItem.text
	response.write (MyColorText)
End Sub

</script>
<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>
<body bgColor="<%response.write(MyColorText)%>" >
<form runat="server">
  <asp:dropdownlist ID="MyDropDownList" runat="server"></asp:dropdownlist>
  <asp:button text="Hit Me" onCLick="ColorSelected" runat="server" />
</form>

</font>
</body>
</html>

Problem is here: bgColor="<%response.write(MyColorText)%>"

ok, you just need to move the line

Code:

Dim MyColorText as String

outside the Sub so that the variable is declared and available at the page level:

Code:

<%@ Page Language="VB" ContentType="text/html" ResponseEncoding="iso-8859-1" %>
<script runat="server">
Sub Page_Load()
	If NOT ispostback then
		Dim ColorArray(4) as String
		ColorArray(0) = "Blue"
		ColorArray(1) = "Red"
		ColorArray(2) = "Green"
		ColorArray(3) = "Yellow"
		ColorArray(4) = "Orange"
		MyDropDownList.DataSource = ColorArray
		MyDropDownList.DataBind()
	End if
End Sub

Dim MyColorText as String
   
Sub ColorSelected(Source as Object, E as EventArgs)
	MyColorText = MyDropDownList.SelectedItem.text
	response.write (MyColorText)
End Sub

</script>
<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>
<body bgColor="<%response.write(MyColorText)%>" >
<form runat="server">
  <asp:dropdownlist ID="MyDropDownList" runat="server"></asp:dropdownlist>
  <asp:button text="Hit Me" onCLick="ColorSelected" runat="server" />
</form>

</font>
</body>
</html>

You can try this:

Code:

Sub ColorSelected(Source as Object, E as EventArgs)
	response.write (MyDropDownList.SelectedItem.text)
End Sub
