irfan said...: This is an upgrade of an existing non-AJAX version which i posted on code project a while ago where i explained all the implementation details which remains same for this version as well with a few exceptions that are specific to the UpdatePanel i have used in this version.

Please check it out here:

For the best results, I would suggest you to use Firefox. Let me know if above link doesn't help you.; 30 July 2009 at 12:20

irfan said...: Hi,

The control delays loading and populate itself only upon clicking the arrow image button. Considering this behavior, you can enable/disable list-items in DataBound event for CheckboxList (cbl_DataBound). In order to do it from the page, the control should implement IList that will give ListItemCollection which can then be used to control the behavior of individual items.

irfan said...: Hi narmadha,

The scrollbars are defined by the overflow property of the main div (dvMain) in style sheet. I have checked it appears in IE, Firefox and Chrome. Let me know if you are using a different browser or a different version?

Anonymous said...: Hmm - it's just the display title which doesn't keep the text after postback.

But can you tell me why C# version does automatic postback after close while VB version does not?

Thanks; 20 April 2011 at 15:17
