When you have any field validators, they will always validate the choosen control on any event that posts the form. This is for validation on the client side. I have found no easy way to disable a validator on a particular button press. For a simple solution, your options are pretty limited. If you eliminate validation on the client side and only validate on the server side you could easily disable the validator when you handle a specific button press. In your scenario, the button's in the datagrid that handle the datagrid item events would disable the validator for the textbox that is outside of the datagrid. You'd need to disable the validator, check for page validity, then reenable it before you exit the handler so it will actually still validate on the next post.

You might want to look into EditItemTemplate. It won't check the requiredfieldvalidator until after the edit button is clicked.
Also make sure you have
If Not IsPostBack Then
your_data_grid_bind
End If block.
That way it doesn't refresh your data with every click.

im not sure is this will help,
1st, u set the validator's Enabled properties to false at the start, then when the user click on edit, u set it back to true.
i was tried to use this b4, but failed, coz the funtion comes up delay 1 step.
(for my case) u might give it a try.
For my dataGrid, i use a loop to check whether there is a blank text box. the example code is like below:
dim i,j as integer
dim params(3) as string
dim strText as string
dim blnGo as boolean= true
j=0
for i =1 to e.Item.Cells.Count-3
strText=Ctype(e.Item.Cells(i).Controls(0), TextBox).Text
if strText <> "" then 'Check is there any box is empty
params(j)=strText
j=j+1
else
lblMessage.Text="u forgot to enter a value!! Update Failed!!"
blnGo=false
end if
next
if not blnGo then
return false
exit function
end if
dim strsql as string="UPDATE SG SET Name='"& params(0) &"', IC='"& params(1) &"', StaffID='"& params(2) &"', Password='"& params(3) &"' WHERE ID="& Ctype(e.Item.Cells(0).Controls(1), Label).text
if there is a blank text box, it'll prompt the user.
and for the strsql string, its better to use parameters to update it. otherwise, when user type ' or some simbols, it'll show u error.
(prevent sql trancated)learned From Mr.Peter
Hope this help
