asp.net: I want to fix the height of checklistbox control so that
when items exceed the height, than vertical scrollbar

You can put your Checkboxlist into a fixed size area by putting it in a div
such as this:

<div id="Layer1" style="position:relative;width:350px;height:200px;
overflow:scroll;">CheckBoxList Goes Here</div>

The key is to use the "overflow" CSS attribute.
Here's more info:

Another option is to put your Checkboxlist in an IFrame.
