Hi all, just to update you on what I ended up coding ( please advise if there's a cleaner way )

// This method clears the controls values.

this.txtFirstName.Text = "";
this.txtMiddleName.Text = "";
// And so on for the other controls.

// Loop to WriteValues to dataset

for(int i = 0 ; i < this.Controls.Count ; i++)
    if(this.Controls[i].DataBindings.Count > 0)
        for(int j = 0 ; j < this.Controls[i].DataBindings.Count  ; j++)
            this.Controls[i].DataBindings[j].WriteValue();

I thought the whole point of DataBinding was to automate this sort of behaviour. Once again, thanks for your help.
