You have to loop through... in that event.. for every object in your arraylist... and I dont see where you have the object name as part of the object???

'in your changed event, just hand-coded using guesses of your code...
For Each Obj as MyObject in MyObjects
      If Cstr(Obj.CompanyName) = cboCompanyName.Text then '<-- MyObject.CompanyName is the company text of your object, didnt see that in the code above?
             txtPDate.Text = CStr(Obj.PurchaseDate())
             txtShares.Text = CStr(Obj.Shares)
             txtPPrice.Text = CStr(FormatCurrency(Obj.PurchasePrice()))
             txtTValue.Text = FormatCurrency(Obj.TotalValue())
             txtWorth.Text = CStr(FormatPercent(Obj.TotalValue() / Obj.TotalValue()))
             Exit For
      End If
Next

*also, all of the CStr shouldnt be necessary. If they are already a string, no need to cast them into a string. For the ones you need to cast, you can use just .ToString()
