In this article, we have shown a way to use custom columns to enhance the functionality of a data access page based on the DataGrid control. We have also designed a generic way for DataGridHelper to work with custom columns. Although this method is not quite as easy to use as the two-way data-binding promised in the upcoming ASP.NET 2.0, it is a more reusable way to extend the functionality of the DataGrid control.

he control is very cool.
I have a question regarding the DataGridHelper control:
1. why do we need a DataGridHelperconnector component? the web component is disappeared in asp.net 2.0

2. can we set the properties dataAdapter, datagrid to browsable instead of using the connector? so that we can set these properties at design time.

I'm lokking forward to your answer, Thanks

I would like to thank Robert for pointing out the bug in part 2 of the article. The bug was discovered during the writing of the part 3 of this series and fixed. Readers are urged to use the code from part 3.

Great Article. One of the best I have read in some time.

I did find a small bug and added the following line as line 134 in the DataGridHelperConnector.cs (in version 2)

134 if(_dataGridHelper.DataGrid != _dataGrid)
_dataGridHelper.DataGrid = _dataGrid;

Without this check, the program creates two event handlers for the SortCommand. This results in the new sort order always being DESC. It also caused multiple reloading of the grid.

Any computer science program should know the basics of languages similiar to Java, C++, C, or the like. It is not very hard to convert C# code to VB code and since this article really explores Data Structures & Algorithms approaches it is pretty easy to convert. You should study this article, and if you need VB, try to write the code yourself. There is probably an advantage to having this as C# code -- although the CLR may not care.

The download does include the VB version of the DataGridHelperTest project.

It would be even better if there was some vb.net code to go with it - not everyone speaks C#.
