Hello,

you can use inline code instead of code in behind. E.g. you can insert button and label this way:

<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click"/>
<asp:Label ID="Label1" runat="server" Text="BeforeClick"/>

Then you can enter following code to handle OnClick event:

<script runat="server">

protected void Button1_Click(object sender, EventArgs e)
{
Label1.Text="AfterClick";
}
</script>

Unfortunately, in transformation you cannot use IntelliSense.
