The DeleGrid is a paged GridView control that handles data-binding through the use of events and delegates rather than with a traditional collection.
What this means is that you have full control over the data that is shown in the currently displayed page. Traditionally you’d retrieve the whole recordset then page it locally, but with the [...]
I’ve updated the ObjectField to be considerably simpler than it was before. While writing my Data-binding hierarchical objects post I wrote this about the BoundField implementation:
Using a TypeDescriptor to get the property… This strikes me as a bit odd to be honest, because the DataBinder has the ability to evaluate a hierarchical path.
Which is interesting, [...]
After my post about my ObjectField column, I thought I’d elaborate a bit on why it’s necessary.
When you’re data binding against an object that isn’t flat (i.e. has properties that are more than simple types - namely classes), you are bound to encounter the following exception, which is caused by the BoundField incorrectly handling a [...]
The version of the ObjectField that this post refers to is now out of date. Please go to the ObjectField 1.1 post for the latest version.
I encountered a problem while binding a complex object to a GridView, in that the BoundField doesn’t support specifying a nested value in it’s DataField property. So if you have [...]
Introducing the DeleGrid
The DeleGrid is a control derived from the ASP.Net GridView, that delegates its data retrieval back out of the control. This allows the developer full control over the records that are retrieved, thus allowing proper paging to be implemented using whatever collection type you prefer.
Why the DeleGrid?
It came about because I wanted a [...]
I started writing this as a comment, but I felt it’s own post was deserved.
Ricky Clarkson left me a link in a comment to one of his posts that ties in quite nicely to my recent Getting with it: Test Driven Development post.
Ricky makes the point that TDD can be dangerous, and can lull you [...]
Test-driven development is a practice that has started to make some serious headway into the average developer world of .Net. The tools have reached a stage of maturity where they offer solutions to most (if not all) aspects of test-driven development. Alongside the improved tools there has been a dramatic increase in the quantity and [...]
The demise of CSS hacks, something which has been covered elsewhere to no end, definitely a good thing, but not what I’m covering here - not directly anyway. I’ve been wondering if we can take advantage of this new age of “hack segregation”.
The way I see it is we’re already breaking the rule of separation [...]
Update: Added separate versions for SQL Server 2000 and SQL Server 2005, due to the differences in the system objects tables.It may just be me, but when writing migration/create scripts for use with SQL Server I get quite agitated at having to write an ugly, long-winded, drop statement at the start of every object definition.
The [...]
ASP.Net has an interesting way of handing the potential ID conflicts caused by embedding third-party controls within your web-page; it prefixes any sub-controls with their parent’s ID.
<asp:TextBox ID=”txtUsername” Runat=”server” /> within a standard page simply has an ID of txtUsername within the HTML output. On the other hand, the following example would result in something [...]
