------ Solution ------- -------------------------------------
GridView1_RowUpdating event in the background to get to value, you can use regular expressions determine whether it is digital .

- ----- Solution --------------------------------------------
text box bound keypress event , call the js validation
function MustNumber ()
{if (((event.keyCode> = 48) && (event.keyCode <= 57)) | | (event.keyCode == 46)) {event.returnValue = true;} else {event.returnValue = false;} }
------ Solution --------------------------------------- -----
GridView- edit field - put the field into a template - and then put a text box + a validation controls
can automatically determine whether a number, if not a number , text boxes, followed by prompt
validation controls built in toolbar
