Hi,



I'm trying to implement the interfaces to make a third party control (Telerik RadComboBox) bindable to SF business objects.



From what I've gleaned from other messages in this forum, I should look at the source code in the SF DropDownList and copy all the code from there into my subclassed control, correct?

Sorry, the topic title should read "Implementing IWebBusinessBindable"

I just tried copying the SF DropDownList interface implementations for IWebBusinessBindable and IWebListControl. I finally got past a symptom of my inexperience and got the event implementation figured out. But I think I've run into a wall and I think it has to do with Telerik RadComboBox control not having ListControl in it's inheritance hierarchy. The IWebListControl.PopulateList() method relies on the derived class being a sub-class of ListControl. So if this strategy isn't possible, it isn't possible to bind directly to a BO I guess.



Just as a suggestion, and I'm far from an expert, but what if you were to change the first parameter of WebListComob.PopulateCombo() to type IWebListControl instead of ListControl, wouldn't I then be able to pass "this" to it and it would be able to use it. "this" being the new sfRadComboBox : RadComboBox, IWebBusinessBindable, IWebListControl class?



Nevermind, that would probably throw off alot of other code, but if you look at the method's logic you'll see that that parameter is used as an IWebListControl everywhere it's used.



If that's not an option (understandable), what other option do I have?



I would really appreciate any help a developer could give me on this because this seems like a major roadblock to using native SF binding with third party web controls.



Thank You,

Govinda

IWebListControl is actually our own interface used for our custom list controls. You don't need to pull that accross to make the telerik control bindable, so that is probably the source of your frustration .

By just implimenting IWebBusinessBindable and going through and making sure all the properties that impliment IWebBusinessBindable are properly plumbed, it should expose your custom control to the strataframe binding, which is all you need.

So strip out all of the IWebListControll implimentations and properties, and let us know .

Thanks Dustin, I'll try that now.

Ahhhh... I see now, just implement IWebBusinessBindable and you can set BusinessObjectName and BindingField properties in to bind a property (SelectedValue, Text, etc.) to a BO property. But I have to populate the dropdown with values some other way (I'm using WebBusinessBindingSource), unless I want to implement the IWebListControl.



Attached is the code showing that binding to a third party combobox is pretty much the same as setting up binding to a third party textbox.



Thanks for the help.

Yep, it's pretty straight forward .

Glad you got it working!
