Datgridview cell validation
<p>I have a datagridview with 3 columns and 19 rows.first two columns are read-only. The last column has values already set to 0. User has to input integer values in the last one and I need to validate if it is an integer.if not display message "Enter Integer". I came across the cellleave event and i was thinking it might be the right one to use to perform the check but i don't know how to call that event automatically.</p>

<p>To summarise</p>

<p>-- Values in 3rd column of datagridview already set to zero.</p>

<p>--user inputs value in 3rd column.</p>

<p>--if value is not integer display message "Please enter integer" </p>

<p>I am a beginner in c# and would really appreciate any help on that matter.</p>
