| 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 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. |

| 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. |

| ASP.NET 2.0's Client Callback Feature |
| DotNetJunkies |
| One of the most overlooked features of ASP.NET 2.0, part of Visual Studio 2005 or "Whidbey", is the Client Callback feature. This feature allows you to programmatically call server-side methods through client-side JavaScript code without the need for posting back the page. This article describes how to use the Client Callback feature to implement your own callback scenario and introduces the new TreeView control that has this feature built in. |

| ASP.NET Validation Controls |
| DotNetJunkies |
| Input validation can be a tricky thing. Ideally we should validate the data on the client side to prevent unnecessary round trips to the server. That requires JavaScript. But not every browser out there processes JavaScript (hard to believe, isn't it). And even still, changing the display characteristics to show errors in the input is not always supported. Not to mention, a slightly unethical person could recreate your page, and bypass the validation all together. Ugh! This leaves us with server-side valida |
