Adding Event on a .NET User Control

There is an C# Windows User Control for editing html document.

[url removed, login to view];tabindex=10

1] This control doesn't have any event for changing innerHTML. I mean, if the innerHTML is changed, an event should be triggered same like a TextBox has TextChanged event.

2]In addition to the previous requirement, I would want to add another feature on this User Control, that is,

"MAKE THE InnerHTML property boundable to a datasource."

I mean, I want to bind the InnerHTML prpoperty to a data member of a binding source.

- Please use Visual Studio 2005 (.NET 2.0)

I have attached the Opensource C# project file.

=============== Details about the Requirements ====================

In order to give you a clue, just take this code,

Once you develop the Event Handler for InnrHTML, you can override that event handler with the following code

private void innerHtml_TextChanged(..........)

{

PropertyDescriptor innerHtmlPropertyDescriptor = [url removed, login to view](null)["someDataMember_of_type_string"];

[url removed, login to view]([url removed, login to view], [url removed, login to view]);

}

private void myBindingSource_CurrentChanged(object sender, EventArgs e)

{

PropertyDescriptor innerHtmlPropertyDescriptor = [url removed, login to view](null)["someDataMember_of_type_string"];

[url removed, login to view] = (string)[url removed, login to view]([url removed, login to view]);

}

......................................

Now, This is the actual piece of code I think all you need. But What I want is as follows :

1] I dont want to see these codes other than designer.cs. I just want a piece of mind about dragging the control from toolbox on to the Windows form. Then when I will double click the form, the default event handler will be created as innerHTml_Changed(......) in my code behind C# file. then I should be able to enter my business logic for this event,

2] At the same way, I dont want to scatter logic on a binding source's Current Change event handler. I should be able to use Visual Studio 2005 Property editor for the htmlEditor control by selecting the control in design mode. Then, within property editor, I should be able to choose a bindingsource's data member (of course STRING type) to bind with innerHTML property. Then whenever I scroll over the binding source using a Binding Navigator Control, the htmlEditor should be loaded with new value from the bindingSource automatically without writing any code (same like we bind Text property to a binding source;'s data member of TEXT_BOX Control). In that way I will also be able to choose this htmlEditor control for any text dataMember of any dataSource within the design mode of Visual Studio 2005.

I hope I could explain you the point.
