The Problem Today I had a hard 2 hours, and if you have found this blog post, I bet we are in the same shoes. I was working on a ASP .NET + windows azure project, and I needed the HtmlEditorExtender control from the Ajax Control Toolkit . I was lucky to find a control for my needs. So far so good. I've installed the toolkit with NuGet Package manager, it added a reference to the assembly to my web.config. I've used the following code where I needed the HtmlEditorExtender: < ajaxToolkit:ToolkitScriptManager runat ="Server" /> < asp:TextBox ID ="txtComments" TextMode ="MultiLine" Columns ="60" Rows ="8" runat ="server" /> < ajaxToolkit:HtmlEditorExtender TargetControlID ="txtComments" runat ="server" /> </ asp:Content > Just to see how this control works. As you can bet ajaxToolkit is the refe...
In this article I will show you how to display hierarchies in a TreeView control, when your data is in a DataTable. In this example we have an Employee table with 3 columns: ID, ParentID and Name. ParentID is the ID of the boss for the current Employee. The first step is to sort the table by the ParentID . This step is really important because we cannot insert a node in the tree until it's parent is not inserted. Notice the root of the tree having a ParentID of -1. Here is the code for this: The second step is to use a XmlDocument. The TreeView control does not have the functionality to find an arbitrary node given a node ID. A recursive find function seems to be too much hassle, not to mention the performance, so I decided to take advantage of the XPath search capabilities of XmlDocument to find a given Parent node. Here is the code for this: The third step is to hook up our data to the TreeView. If you try to bind the TreeView control to an XmlDocument you w...
Disclaimer: I'm not a python developer :) Yesterday I've found a tool that I needed, it was written in python. Nothing special, get a list of links from a csv, login to a page, and access a link from the opened page by match. The script was old(2 years), and it needed some refinement, but I managed to make it work to start griding my over 7000 links, after 30 minutes later I saw it crashed with a strange error: UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 50: ordinal not in range(128) I've started to investigate the issue, found some information on stackoverflow, but I was confused, I don't really know python that well. What I've found is to make some changes in the config files from python, which I don't really know how to do and it was not recommended, or to use decode('utf-8') function on the string variable and usage that caused the issue. As you can see in the full error log, listed down below, I tra...
