Hi Gary

Thank for your help, sorry for unclear of my second question, let me explain in details.
I create a form with parent and child table, by using the same style with "pizza" sample as come with tutorial of codemine,
I did not use grid control to handle child table, instead I use textbox control and combine with Lstlistnavigator control, every time
when I input a new child record it will reflect in LstlistNavigator control also, this is my concept.
My problem is, my child table comprise of 3 fields, first is charactor and the others are numeric field.
When I input a new child record, the first field , which is charator it will reflect also in LstlistNavigator immediately with no problem,
but when I input 2nd & 3rd field which are numeric as soon as I input the figure and press enter the textbox control became dim
and not show the figure that I input, also in LstlistNavigator did not show, just show zero, I must move the mouse
pointer and click at that row and that field in LstlistNavigator the the zero value will become the exactly value that I input and in textbox will
become normal (not dim) and show value also.
If your have any idea to suggest please. Thank.
