Code Camp

Are you a programmer? Are you looking to learn more, expand your horizons and meet some other coders in the process? Then you should check out SoCal Code Camp. It's an all volunteer roaming school that is completely free. They have some great sponsors including Microsoft so they are well backed and have lots of options. Sometimes the classes are brain dumps and other times they evolve into in depth discussions. Plus, they are always held on weekends so they don't interfere with the work schedule.

Could not find control 'ddlColor' in ControlParameter 'ColorID'.

Here I'm using a DetailView to update or insert into a SQLDataSource. However, the control parameters are not found for my dropdownlist. The error message is: Could not find control 'ddlColor' in ControlParameter 'ColorID'. Here's an example of my UpdateParamenters.

<updateparameters>
<asp:controlparameter defaultvalue="0" type="Int16" propertyname="SelectedValue" controlid="ddlColor" name="ColorID">
</updateparameters>

SOLUTION
Since the page cannot find the control, you have to specify that the control is inside the DetailsView. Use DetailsView1$ddlColor for the ControlID. Here's the correct syntax.

<updateparameters>
<asp:controlparameter defaultvalue="0" type="Int16" propertyname="SelectedValue" controlid="DetailsView1$ddlColor" name="ColorID">
</updateparameters>

What is .NET Now What?

Welcome to .NET Now What?! This is a collection of hard to find solutions for unexpected and unexplainable errors you might get during programming with Visual Studio. I mainly program in VB.NET using ASP.NET and ADO.NET with Microsoft SQL Server on the back end.

I've been programming for 12 years. I started with Perl in a linux environment. I've written my own shopping cart completely in perl using a mysql database. You can see it in action here:

I moved on to VB.NET in 2004 and have contributed to many websites since then. I have also written windows applications, windows services and most recently my first smartphone application.

If you are a fellow programmer and find yourself stuck along the way, I hope you find some of my postings helpful.
