I'm using MySQL in an ASP.NET project I'm currently working on, I did some tests to test the performance of the MySQL .NET provider but unfortunately I'm not very pleased with the results. A very simple loop that only opens the connection was 10x faster in SQL Server: // MySQL const string CONNECTION_STRING = "server=localhost;databa...

I am using nested repeaters to build a table for reasons I won't discuss here, but what I'm looking to do is have two datasources, one for the top level repeater that will correspond to the rows, and one for the second level repeater that will return cells within a row.

I work on a web-application that is written in C#/ASP.NET. The original framers of this application chose to use encrypted query strings and Viewstate to control the 'security' and 'state' of the application. Having come from a GET/POST world before this, I don't have a good basis for understanding why people would go through the troub...

In any case, the apparent solution to this is to make sure that the TagName is the name of control class. So for my example, the following displayed the warning: <%@ Register Src="~/path/to/Control.ascx" TagNam...
