Re: DNN Best Kept Secrets Part 1: DNN Paging Control

I agree. It is a great control. I actually submitted a revision to the control to add a "Jump to" page function and also a PageSize drop down list. Hopefully, it will get added in the next release.

Re: DNN Best Kept Secrets Part 1: DNN Paging Control

@mathisjay: Yes, I agree. The page size drop down would be cool.

Re: DNN Best Kept Secrets Part 1: DNN Paging Control

please be aware, that there is a limitation in current implementation of the control: if it is used more than once on a page, all instances will change pages simultaneously.

Re: DNN Best Kept Secrets Part 1: DNN Paging Control

@leupold: that is a good point, however you could add an additional querystring parameter to the control (ctlPagingControl.Querystring = the_control_sender_id) and load the datasource based on that parameter only.

I hope this makes sense.

Re: DNN Best Kept Secrets Part 1: DNN Paging Control

I must say, I am not a fan of this control - I use it heavily in the Smart-Thinker modules. Everything is done using querystring params, so if anything else on the page does a postback you have to persist the state and URL so that it continues to work (I remember doing a forum post on this a long time ago - it causes major problems if you have more than one on a page (as Leupold pointed out) - I'll have to dig it out to explain the limitations I encountered...

Re: DNN Best Kept Secrets Part 1: DNN Paging Control

I have reworked the control to keep its own state without any special interaction from the hosting container. I've also fixed it so you can have multiple instances on the same page.

I'll have it submitted in the next few days.

The primary reason everything is done via querystring params is so that it works well with SEO bots. Those things can't follow linkbutton postback clicks or AJAX callbacks as well as simple hyperlinks.

Re: DNN Best Kept Secrets Part 1: DNN Paging Control

@rodney: Inside UDT3.4.0 is an alternative to the core paging control. It renders exactly the same way as the core control. It is based on viewstate instead of querystrings.

Re: DNN Best Kept Secrets Part 1: DNN Paging Control

mathisjay raises a good point though: postbacks are not SEO compliant... as I mentioned there is a way to overcome that limitation by using the Querystring property and adding the control id of the datalist you want to page. In your code you handle the appropriate datalist control based on the querystring.
