How to select entire row of a Datasheet form

Hallo my friends,

I have a problem in my MS Access project that is I have a subform in my form. This subform is in datasheet view to show the 1 - N relation between the mainform and child form.
Now the problem is when the user changes the data from another form I must show which row is edited by selecting the entire row of the subform which was edited, I can find which was edited and also I can jump to thta row by FINDRECORD method of VBA. But I don't how to select or mark the entire row.

I am attaching the screen shot my form to show how I want to select the row in the subform please have a look, if u don't understand it.

Please help me.

Thanks in advance.
