Dino Esposito builds an ASP.NET 1.x custom control that mimics the behavior and the programming interface of the ASP.NET 2.0 DetailsView control.

A simple RadioButtonList in a Web DataGrid Column

The AlternatingItemStyle can be a wonderful thing. But in many cases I found that I would start to get a feeling like vertigo if I scrolled the page up or down. So I thought back to my days in Manhattan in the financial industry and remembered how I used to prepare reports to be viewed on screen. I alternated the colors of the rows, but I did it every three or five rows (depending on the width of the report, the content of the report, or my own aesthetic taste).

A Truly Excel-like Grid Control

A very simple and practical way, how a single RadioButton acts as a RadioButtonList in a web DataGrid server control column.

Adding a "Totals" Field in a DataGrid

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.

Adding a Blank Row to a DataGrid (Used to INSERT rather than UPDATE)

Lately one of the questions that has been popping up a lot is, "How do I show column totals in a DataGrid?" Personally I have provided sample code for this question more than a few times, so I thought it would only be appropriate that we here at DotNetJunkies HQ get a tutorial up on the topic.

Adding a Totals Field in a DataGrid

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.

Adding and Using RadioButton to DataGrid in ASP.NET

Building a DataNavigator Control

Is it possible to port this model to Web Forms and get automatic synchronization between two DataGrid server controls? This is the question I will try to answer in this month's column.

Building a Full-Featured Custom DataGrid Control

The list of ASP.NET rich data-bound controls is a long one, but it's not all-encompassing. You won't find any Microsoft® .NET counterpart for the Data control—a scrollable and updateable binding context that data-bound controls could rely on to refresh their user interface. The original Data control allowed for simple movements—first, next, previous, and last. It worked on top of a Recordset object and exposed the UpdateRecord method to save changes according to the capabilities of the currently selected type of cursor. While not the perfect programming tool, the Data control was especially good at building simple user interfaces for tables used internally for administrative purposes.

Building a Master/Detail DataGrid

In this article, we will examine and implement these very features and demonstrate how you can build your very own Datagrid control component, one that you will be able to customize, and more importantly reuse. Based on this ability, you will then end up with one powerful control that will have many implementations, from which you could learn about creating almost any other types of custom controls.

Creating a Fully Editable DataGrid

"I have a question regarding DataGrid. Can I bind a column of a DataGrid to another DataGrid? I have a situation where I have to display a few details in the same DataGrid on click of a HyperLink column." This can certainly be done. You are describing a master/detail DataGrid. For example, a DataGrid of customers with a column in each row that has an embdedded DataGrid of all the orders placed by that customer.

Creating DataGrid Templated Columns Dynamically

In this example I have written a simple WebForm to manage a list of contacts which I have stored in XML. The requirements are simply the ability to add new contacts and to be able to modify or delete existing contacts. The user should be able to modify or delete multiple contacts at one time. I have also allowed the user to sort their grid by the column of their choosing.

.netBips

Few months back I wrote article on how to create DataGrid programatically. The article explained how to created a DataGrid with bound columns on the fly. Many readers asked whether we can do similar thing with templated columns. This two part article explains just that. There are actually two ways to create DataGrid templated columns dynamically - using LoadTemplate method and implementing ITemplate interface. In Part - I, we will discuss how to use the first method i.e. using LoadTemplate.

Editable DataGrid without link buttons

DataGrids seem to be very popular among all ASP.NET developers these days. I've seen whole series of articles and a lot powerful custom controls released for it. I personally think they are great as long as you manage your ViewState size and don't try to think too much outside the box, or grid in this case. Anyhow, one thing that has bothered me is that it isn't easy to wire up events like, OnSelectedItemIndexChange, in template columns containing controls like the RadioButtonList or DropDownList.

Questi on: I would think this is obvious but I must be missing something. I want to trigger the visible value to determine whether to show the the "EditCommandButton". I tried a conditional statement () in front of it but the compiler said no. Then I tried a declaration () - but was shotdown again. Has anyone run across this... and solved it? thanks in advance.
