How to create a custom Gantt Chart for SharePoint using VS

So I have been told you can't create a custom gantt chart using SharePoint Designer.  I don't believe that actually, there must be a way to create one from scratch using SPD and a Data View and editing the XSL directly....but assuming there is not..

Are there any articles that explain for a non-developer how to create a custom gantt chart for a SharePoint site using Visual Studio 2008?


Missing Points in Chart Series

Okay so I have 3 series that are created from Cross Table Data Bind. Unfortunately some of the points are missing. Is there an algorithm I can use to cycle through the datapoints for each series and insert empty points to the correct spots so that my data is displayed correctly?

Display Images from a Custom List's Attachment Field

i need to show each item on the list with image that was uploaded to its attachments field. the idea is that this list is a news list and will be show as a grid with the news and their corresponding attached image. i tried to add a custom column of type Picture, but it only allows to have a hyperlink added. i need the ability to upload the image on a new item creation form.   if there is a way to display it that would be great, if not please recommend a way to accomblish what i have explained.     thanks  

Expression to pick a chart series color by ordinal from custom palette



This is probably an easy question but I cannot find a solution to this. The stored procedure that I use to retrieve data for my bar chart in SSRS returns an ordinal number for each row, which represents a group the item belongs to. For example, I get:

Car - 20% - 1
Bus - 10% - 1
Train - 15% - 1
Bike - 3% - 2
Inline skates - 16% - 2

so 1 is all vehicles with an engine, and 2  all vehicles without engine. What I would like to do is to plot a bar with the percentage for each row and in the color of the custom palette, so Car, Bus and Train would get the first color of the user defined palette, Bike and Inline skates would be the second color of the custom palette.

I think I have to use the Choose function in the expression for this but I cannot figure out how to access the custom palette to retrieve all colors.


I know I could retrieve a color code from the database instead of the group ordinal, but I would prefer to have the color being picked from the custom palette; is this possible?

Thank you,



Custom Controls in C# .NET

Embedding user controls in a Windows form is just like adding a simple button or text box that are already provided with .NET. These basic controls were written essentially like you code your own controls. Typically the controls you design are to be used in multiple forms or to modularize your code. These reasons help reduce the amount of code you have to type as well as make it easier for you to change your implementation. There should almost never be any reason to duplicate code because it leaves a lot of room for bugs. So, implementing functionality specific to your control in the control's source code is a good idea. This reduces code duplication as well as modularize your code, which is a good programming guideline.

Writing custom MembershipProvider

ASP.NET Membership mechanism allows to use the build-in server tables to store and retrieve user data. By default, this mechanism can only be used with SQL Server database to which Microsoft provides suitable MembershipProvider class.
Inheriting from this abstract class, developer can use his own table(-es) from any database and use any database engine other than SQL Server, like Oracle, DB2 etc.

Custom Editing Behavior for DataGridView TextBox Columns

For various reasons I'm using a DataGridView instead of a ListView, and while configuring the DataGridView to look like a ListView wasn't much of a problem, there's one thing that got on my nerves, which is the behavior of textbox cells in edit mode: It is much too easy to leave the edit mode accidentally, simply by pressing the cursor keys at the wrong time. For example when the text caret is positioned behind the last character of the textbox cell content, and you press the right arrow key

Write Custom WebParts for SharePoint 2007

The popularity of SharePoint Portal Server 2003 led Microsoft to tightly integrate the next SharePoint version, Microsoft Office SharePoint Server (MOSS) 2007, with its ASP.NET 2.0 WebPart framework. This tight integration enables the ASP.NET and SharePoint developer to do a number of things that previously weren't possible

Writing Custom Web Parts for SharePoint 2007

As I mentioned in an earlier blog post, SharePoint 2007 is built on top of ASP.NET 2.0, which means you can now use ASP.NET 2.0 features (Forms Authentication, Master Pages, Membership, Site Navigation, New Data Controls, etc) when building SharePoint sites. This is true for both the new Windows SharePoint Services 3.0 version (which will be a free download) as well as Microsoft Office SharePoint Server 2007 (which costs money).

Reading and Writing Images From a Windows Mobile Database using UltraLite 10(C#)

Periodically I get a request for information on how to read and write binary data to a database running on Windows Mobile. If you search the Internet you can typically find examples that are available on Windows Desktops or allow you to read and write to a local file system. The problem is that it can take a bit of work to get this code to work on Windows Mobile accessing a database.

Ultimately you might be asking, why would I want to store and image in a database? Well in an environment where you synchronizing data between a local mobile database and a consolidated (central) database this can be extremely useful. Imagine if an insurance adjuster went to an accident scene, took a picture of a damaged car, loaded it into his Windows Mobile database and then replicated that image up to the Insurance headquarters for approval. All of this could be done in a very short period of time when using images in the database. Another good example might be a doctor who was waiting for a patient chart to become available. If you could store the image in a database this chart could be sent down to the doctor's device once it became available.

For this article I am not going to get into how to synchronize the images to and from a remote and central database as this is typically fairly straightforward when using a data synchronization technologies like MobiLink

Save images to SQL CE

Storing binary objects (such as image, office document etc.) into database is a little cumbersome when it comes to retrieval. Hence the most commonly accepted way is only store the file path in the database, and to store the documents on a file share.

Calculate distance, bearing and more between Latitude/Longitude points

This page presents a variety of calculations for latitude/longitude points, with the formulæ and code fragments for implementing them.

All these formulæ are for calculations on the basis of a spherical earth (ignoring ellipsoidal effects) - which is accurate enough* for most purposes. [In fact, the earth is very slightly ellipsoidal; using a spherical model gives errors typically up to 0.3% - see notes for further details].
