| A DropDownList, EditItemTemplate, using Access, and HttpSessionState...Part 3 |
| DotNetJunkies |
| Here we are at part three of this article! In this part we will be adding one new feature to the code! Instead of making a call to the database to get the data on each request we are going to be saving the <b>DataSet</b> into session state. We will not only be populating the <b>DataGrid</b> and <b>DropDownList</b> controls from this <b>DataSet</b>, but we will also be saving all the edits done by the user. This means that after the <b>DataSet</b> is initially created and put into session state there will be |

| A Simple ASP.NET Server Control: Message Box & Confirmation Box |
| The Code Project |
| An article on creating a simple ASP.NET server control that functions as Message Box and Confirmation Box |
|
| A Truly Excel-like Grid Control |
| MSDN |
| The ASP.NET DataGrid control generates an HTML output that really seems to be the Web counterpart of a Microsoft Excel worksheet. In addition, the control supports features like selection and in-place editing that can only further confirm this similarity. With in-place editing, in particular, the similarities are most clear. You click on a special type of command column and the grid redraws its content using text boxes rather than static text. At the same time, the command column changes the layout, replacing the edit link with two other links—one for saving and one for canceling changes. The overall design looks nearly identical to the Excel name box command bar. |

| Accessing DataGrid Information |

| Adding a Blank Row to a DataGrid (Used to INSERT rather than UPDATE) |
| DotNetJunkies |
| In this article we will be illustrating one way to add a blank row to a DataGrid. Why would you want to do this? Who knows, maybe to enable a user to add a new record. This article will show you how to add a new row to a DataGrid by manipulating its DataSource - in this example a DataTable. Note that we will be simulating saving the new item back to the
database. |

| An Introductory Guide to Building and Deploying More Secure Sites with ASP.NET and IIS, Part 2 |
| MSDN |
| Forms authentication is one of the most compelling and useful new features of ASP.NET. It enables developers to declaratively specify which files on their site can be accessed and by whom, and allows identification of a login page. When an unauthenticated user attempts to retrieve a page protected by forms authentication, ASP.NET automatically redirects them to the login page and asks them to identify themselves. Included here is an overview of forms authentication and what you need to know to put it to work. Also included is hard-to-find information on the security of cookie authentication and on combining forms authentication with role-based URL authorizations. |

| Application of the Cache Subsystem for Web Applications |
| C#Today |
| In this article, Eric Rhea explores two approaches to utilizing the caching system. First, he talks about how to make use of the cache subsystem from the web-form code. Then, he takes a look at exploring how to make use of the cache subsystem in the code behind. While doing this, he seeks three answers: (1) how to improve performance, (2) how to make use of similar techniques in both code areas, and (3) how to cache an object which is indeterminate in length and whose values you do not know in advance, and one which you cannot cache using the web-form directive. |

| Ask the DotNetJunkies: Editing with the ASP.NET DataGrid |
| DotNetJunkies |
| I have bound data to a datagrid, which has ID, name, address columns. But I want the key field (for example ID) as a href so that by clicking on the ID, I can take the user to another page where I can let him edit that record. - Sreedhar Reddy. This is a great question. The best part about it is that the ASP.NET DataGrid server control enables editing of records in a much easier fashion. |
|
| Ask the DotNetJunkies: How do I add a DropDownList to a DataGrid EditItemTemplate? |
| DotNetJunkies |
| I'm working with a DataGrid. When editing a row, I would like to have one
of my fields be a DropDownList. I would much rather be able to bind that DropDownList
to a table in a DataSet so when new key/values are setup in the database they
flow through to my aspx page without having to fuss with it. Please, example
in VB. |

| Ask the DotNetJunkies: Performance Impacts of Server Controls |

| If the validation controls or intrinsic controls post the page back to the server, will it not affect the performance of the pages because huge files have to go back and forth from the client to the server? |
