Great control. Thank you for sharing.
We are trying to implement it in our web project . One issue that i came across is when i tab from one control to another on the page this particular control doesnt get focus to use the keyboard keys. The focus skips this and jumps
directly to the next control in the list. tried tab orders , set focus but nothing seem to help.
I also notioced that in your sample web project the control doesnt receive focus and is not usable with keyboard functions and have to use the mouse events..
I was looking for something that can match the reporting services native multiparam control rendered by the reportviewer automatically if the report(RDL) has multiple value input parameter. This looks like a drop down list control with check boxes but
looks like it has textbox, image and div panel all put together to create the effect and responds well to the keyboard navigation.
