Hi

I have a usercontrol with a property of Text, i am using this within a formview and binding using standard stuff

ie : Text='<%# Bind("ColumnName")%>'

now from within my usercontrol i need to know what the Text property is bound to, i dont want to have to have another property of FieldName and have to set it twice..

Thanks

Ive tried using

IDataBindingsAccessor acc = this as IDataBindingsAccessor;

but its always empty...
I'm trying to follow what you're trying to achieve. Controls should be encapsulated and as such, why would it need to know what property it was bound to on the outside form? Not sure how to achieve what you're asking. but maybe with what you're trying to achieve can come up with a solution?

Yes encapsulation is great, this however is a means to an end and the time saved and flexibility it will bring will be worth it.

I have a user control that will display a textbox wit some autocomplete beaviour etc.. (Telerik RadControls to be precise).
Now this sits inside a formview that is bound to a business object, these object are created from Telerik OpenAccess ORM and as such contain metadata about the object fields, in this case Length...

As an excersise i am trying to evaluate the possiblility of the UI auto detecting the length of varchar/string fields via the orm business objects metadata, this works great if i know the name of the field if you set it via a property but its duplication and as such i would like to either set it via only a property or via the databinding expression...

At current i have

<DIS:TextField id="Field1" runat="server" DataField="UserName" Text='<%#Bind("UserName")%>' />

If i could get away with just the property and still allow 2 way binding then great theres your encapsulation...
