[mono-vb] Bug

[Quan]

Every page should by default include the namespace System.Web.UI.WebControls
because when you declare RowDataBound in every version of Visual studio, 
you just write
Sub gvCurrentNavigation_RowDataBound(ByVal sender As Object, ByVal e As 
GridViewRowEventArgs)

Note that it is GridViewRowEventArgs
And not
System.Web.UI.WebControls.GridViewRowEventArgs
and System.Web.UI.WebControls is not included anywhere.
plus normally you can also just declare Dim x as Button, and not
Dim x as System.Web.UI.WebControls.Button


Also if you have a
Partial Class admin
Inherits System.Web.UI.Page
then this class includes the page namespace, and I shouldn't have to add 
System.Web.UI. in front of everytime I have the "Page" statement 
somewhere in my codebehind.

In the same chapter goes:
HttpContext
for mono it's System.Web.HttpContext
If you have an ASP.NET application in Visual Studio, this includes the 
namespace System.Web.
so you don't have to write System.Web. in front of it everywhere.


Microsoft.Jscript.GlobalObject.escape does not exist
It is a core function, since it's the only place where there is a 1:1 
equivalent of the javascript escape function. Without this function, you 
cannot JavaScript escape a string, which means you are unable to create 
a javascript messagebox which outputs vb.net exceptions.

I suggest incorporating the google v8 javascript engine.
Then you have complete support for any javascript function, you simply 
have to make an interface to it, which is not difficult, at least not 
for this one function.

Another issue:
Declaring this in the aspx:
<asp:Button ID="btnNewNodeOK" runat="server" Text="OK" />

Then, btnNewNodeOK can be perfectly handled with
Protected Sub btnNewNodeOK_Click(ByVal sender As Object, ByVal e As 
System.EventArgs) Handles btnNewNodeOK.Click

note the handles clause.

It cannot be that I have to add every OnClick="btnNewNodeOK" and remove 
the handles statement from the codebehind for all my buttons or any 
other control's events, like linkbuttons.
If I have to do that, I can just as well rewrite the entire code in PHP, 
which would be better anyway, but I just don't have the time.


And then there is another thing:
My treeview serialzation gives a bug:
unimplemented compiler feature. Please file a bug report.

Here all the code in question
Class Debug is for the escape function
all others contain whatever leads to the unimplemented feature error
