Part two of the webinar series occurred yesterday and, just like with the first one, I wanted to follow up with a blog post answering all of the questions that came up. I also wanted to thank everyone that attended, you guys were great and were very attentive (as I saw after reading the chat logs regarding my initial Eval statement!). Your exact question might not be included here, but that’s just due to a duplicate (or very similar) question. You can find all the answers to the questions below:
- Will this code be made available for download the webinar?
The code will be available after the conclusion of the series, or part three, which will occur on August 30th at 11 AM EST.
- Will the webinar recordings be placed on Telerik TV?
Each webinar is recorded and placed on Telerik TV, part one has been available since last week and part two was uploaded earlier today.
- What is a common practice to use: OnNeedDataSource or call DataBind on Page load and then use ajax calls?
It all depends on your particular scenario, and both scenarios can end up being very similar. If you are doing server-side binding with the RadGrid or RadListView, no matter if it’s through OnNeedDataSource or setting it in Page_Load, the controls will go back to the server when paging/sorting/filtering to grab additional data. So while OnNeedDataSource will be fired when the Datasource property has not been set and any of these commands fire, the same will occur with using the Datasource property in the Page_Load event. To prevent a full postback (which is usually the concern) you could take use of the RadAjax control and all of its sub-controls (RadAjaxPanel, RadAjaxManager etc.). This will also be a topic during the third webinar.
- Is OData different than any standard web service?
- Where can we find more information about OData?
The best place is honestly OData.org. Here you can find a full list of Producers and Consumers (including some Telerik Products). What is pretty helpful is that the documentation covers the protocol pretty well, so to get a good understanding of how queries work I definitely recommend reading over that page.
- What version of jQuery are you using?
In this particular demo I’m using version 1.6.2, but most of the code used in this example does not take use of any new features in 1.6.2, so older versions can be used as well if need be.
- You mentioned partial postbacks for performance gains, will you be covering this?
This will be covered in the third webinar, so mark your calendar for August 30th :)
The second webinar is also now uploaded on Telerik TV. Follow this link to see what we went through in the second webinar. For those of you that have not watched the first webinar, found here on Telerik TV, I recommend that you go watch that first as this webinar builds off of the work we did in the first one.
Don’t forget to sign up for the third webinar!
