• Re: How to reference web.config elements from custom control's property builder dialog?

  That's just what I needed! I didn't realize it was in the IDataEnvironment like that. Now it works, hooray! Thanks, Mehdi!

• Re: How to reference web.config elements from custom control's property builder dialog?

  I guess I did a bad job of explaining myself in the beginning. I apologize. I have my custom control, which has a connection string property, among several other properties. I want to have a component editor for that custom control which displays ALL properties in one dialog, which I have had to build seperately. Here's an example skeleton of my control: [ ToolboxData ( "<{0}:ExampleControl runat=server></{0}:ExampleControl>" ), ParseChildren ( true , "Items"

• Re: How to reference web.config elements from custom control's property builder dialog?

  Thanks for the suggestion, ASP.N3T. I hadn't even thought to do it that way. I added your above code to my project, but I'm having some trouble figuring out how to bind the dropdownlist in my component editor. Can I just call ConnectionStringConverter.GetStandardValues() from there? What kind of argument can that take? I've tried to look up ITypeDescriptorContext, but I'm having trouble finding details on exactly how that interface is used. Could I trouble you for another example

• How to reference web.config elements from custom control's property builder dialog?

  I have a custom control which has a property builder. I want to be able to populate a dropdownlist in this property builder with all the ConnectionString elements from the web.config file of the project that the control was added to, the same as is done in the property builder for the SqlDataSource object. I can't seem to find a programatic way to reference that reliably. If I use ConfigurationManager.ConnectionStrings, I appear to get the configuration associated with Visual Studio itself, not

• How to make a Collection of WebControls as a property of a non-rendering control

  I'm working on a suite of controls to be used for easy database communication. I've got a master control that handles all the connection properties and command building and then I have a bunch of controls which inherit from standard web controls like TextBox and Label. The master control needs to be able to refer to the controls which it needs to build its select and update commands, but I'm having trouble finding a way here that works. I've tried having a collection of the controls

• Re: State of items in collection does not update after PostBack

  I was afraid of that. Is there any way to create a collection of control references?

• State of items in collection does not update after PostBack

  I have created some control classes which extend basic .NET webcontrols like TextBox and Label. I have also created a custom collection to hold these controls so that I can easily iterate through them later. This collection is basically just a wrapper for an ArrayList which implements the IStateManager interface. All of this seems to work just fine except across postbacks. The state of the controls themselves updates fine, but if I access them through the collection I've created, their state

• Custom extended controls lose base control values on PostBack

  I have a group of custom classes that extend standard webcontrols: TextBox, CheckBox, DropDownList and Label. These extended controls have a common group of added properties. These are implemented via an interface which the extended controls share. I have another custom class which holds a collection of these objects. Then I have a third custom class that has as one of its properties an instance of this collection class. All of these custom classes implement the IStateManager interface as well. These
