Hi Kevin.
I tried your code and it worked fine.. thanks a lot.

I'm not sure though that I understand why my orignal code did not work.
In VFP, if you specify the ControlSource of an object, it doesnt matter if its a TextBox or a CheckBox.....nothing different needs to be done.

Why this special code in DotNet for a CheckBox... and do I need to do something different also for other types of controls (Radio Buttons,RichTextBoxes,Date-time fields etc)

For instance , to databind a Tel No I Have code like:
this.txtTel.DataBindings.Add("Text",this.dsIFSR,"IFISR.isr_tel");

Why then doed this not work ?
this.txtMyChk.DataBindings.Add("Text",this.dsIFSR,"IFISR.isr_MyChkel");

I reckon its to do with having to bind a 'CheckBox' type to a CheckBox property

Is there any good article around on the area of Binding ?

Regards,

Gerard
