prevent conflicting edits in a gridview
<p>I have a datagridview window which is set to read only. The user has a checkbox to uncheck and then cells are editable.
Now another window of this datagridview can be opened. The second one is opened as read only. The user unchecks the read only box to make editings. </p>

<p>I should make sure that read only is allowed on only one datagridview window 
i:e if the first instance of the gridform has read only unchecked, then before unchecking read only on the second instance of gridform, the first one </p>

<pre><code>TO prevent situation of multiple conflicting eidts, editing should be enable for one DGVform. The user muct reset the currently enabled window to read only
</code></pre>

<p>I dont know how to do this</p>

<p>Thank you</p>
