| 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 |

| Building a Master/Detail DataGrid - Great Article! How would a template column be created and included in the DataGrid that appears in the Orders column. GfWeis - The Answer: Well, first off...thanks for the compliment. Now, let's cut to the chase. What you are asking, adding a TemplateColumn to an embedded DataGrid, can certainly be done. We are going to take a slightly different approach for this however. In this tutorial I will show you how to embed a DataGrid in a DataGrid, with a TemplateColumn in the |

| Coping with a New Beta - Data Server Control Templates and Editing |
| DotNetJunkies |
| The .NET Framework Beta 2 has many changes that will break applications written in Beta 1. Among these changes is the templates used in Data Server Controls, such as the DataGrid and DataList. These are simply syntax changes in how templates are used, not programmatic breaks. In this tutorial you will learn how to use Data Server Control templates. Heck, since it’s a Friday I’ll also show you how to do DataGrid editing at the same time. The downloadable sample code for this article contains files in both Vi |

| Create and maintain a links page using XML as the datasource |
| http://www.swartzentruber.net/ |
| I wanted to play around with the idea of using an XML document to store a group of links. This XML document is read into an ADO.NET dataset table for the purpose of rendering in a datagrid or other databound control. |

| Embedding a DataGrid in a DataGrid |
| DotNetJunkies |
| Well, first off...thanks for the compliment. Now, let's cut to the chase. What you are asking, adding a TemplateColumn to an embedded DataGrid, can certainly be done. We are going to take a slightly different approach for this however. In this tutorial I will show you how to embed a DataGrid in a DataGrid, with a TemplateColumn in the embedded DataGrid. The design for the embedded DataGrid will actually be done in the Web Form, and we will call a method in our code behind class to populate the embedded DataGrid. |

| How do I add a DropDownList to a DataGrid EditItemTemplate? (again) |
| DotNetJunkies |
| It has come to our attention that this article didn't completly anwser the proposed question. Because of this fact we are adding yet another one. In this code example we will be demonstrating how not only show a DropDownList control populated from a database in an EditItemColumn, but how additionally show a TextBox to edit the value of the DropDownlist. Because we are all intelligent programmers I am not going to give a huge background on how editing works and how to use the DataGrid, instead I am going to |

| How do I add a DropDownList to EditItemTemplate, Using an Access Database (And Then Some)? |
| DotNetJunkies |
| In a recent artlicle we discussed how to populate a DropDownList box from within a DataGrid's Column while the DataGrid was in "edit mode". Well, this article builds off that example, and adds some new elements and features. First, instead of using the SQL we are going to use Access - specifically, the Northwind database. Second, when filling the DropDownList we aren't going to make a seperate call to the database to get the data - instead we are going to use a DataView and filter out the specific rows we n |

| Search Pages using Data-bound Controls, Index Server, and ASP.NET |
| DevHood |
| If you've ever created a search page using Microsoft Index Server and ASP, you will probably agree that it's not the easiest task to accomplish. There much you have to plan for and all sorts of paging issues to handle. For the Iowa State University College of Veterinary Medicine web site, I've created a new search application using ASP.NET and data-bound controls. This tutorial will be lengthy and will cover about everything you need to create a powerful search page that does almost everything automatically with ASP.NET Web Server Controls. We will cover querying Index Server with ADO.NET, binding data to controls, serialization using XML, and several algorithms to assist you with query-string creation and drop-down box selection, since ASP.NET's drop-down controls don't automatically select the previous item for you. |
