In some case, we want to display the read-only checkbox in our web form. So, the information cannot be changed. Sure, disabled control will do this but disabled controls change its appearance to grayed-out. We don't want it. There is the easiest way to do that with simple JavaScript. There may be another better way, but I normally use this. We can apply it for other controls as well. What you need to do is just add "onclick='return false;'" in control.



<input type="checkbox" id="chk_normal" value="normal" />

<label for="chk_normal">Normal</label><br/>

<input type="checkbox" id="chk_disabled" value="disabled" disabled="true" />

<label for="chk_disabled">Disabled</label><br/>

<input type="checkbox" id="chk_readonly" onclick="return false;" 
value="read-only" />

<label for="chk_readonly">Read-Only</label><br/>

<input type="checkbox" id="chk_readonly_checked" onclick="return false;" 
value="read-only-checked" checked="true" />

<label for="chk_readonly_checked">Read-Only Checked</label>
