BindingSource and BindingList Of T - DataBinding made simple!

BindingList<> frustration

There is a new set of helper classes implemented in the Windows Forms 2.0 that I am currently attempting to work with named BindingSource and BindingList. Basically they simplify the process of data binding objects to controls.

Unfortunately, most tutor

If you put a blank Grid on a form, what do you have to do to it to get this to work. I don't see anything happen. TIA

Binding to a list of rows with a list of columns

Laughing_John — Tue, 22 Aug 2006 19:02:20 GMT

Hi,

I want to spin up my own version of a datatable to allow me to do virtual loading of the data.

Therefor I have a list of rows with a list of fields.

So I've got

List of Rows
List of Fields
Field1
Field2

etc.

How can I make my mode bindable ? Do I need to inherit Ilist for both lists, and what do I do with each field which will have name, value etc ??

Sorry if I'm being dumb !

I had an situation like this with

"TextBox bound to business objects"

TextBox is handling Validating Event for some error handling. (null/empty string not allowed)

So when i bind the "DataSource" to business object in genral, it clears the TextBox content. (but during initialization this TextBox initialized with "XYZ" data)

i.e bindingSource1.DataSource = typeof(classX)

So i want to ignore this case (also handle the Validating Event which deals at UI level).

Anybody faced this situation and how it is resolved.

I have tried with

bindingSource1.Clear()

bindingSource1.RemoveCurrent(). But all this have impact with TextBox.
