Default Chapter 13 LINQ Page452 Try It Out

Hello there,

I did this Try It Out step by step carefully, but the finaly display is strange. I inserted five Description, Tooltip and ImageUrl, namely (GD1,GT1,GI1),(GD2,GT2,GI2),(GD3,GT3,GI3),(GD4,GT4 ,GI4),(GD5,GT5,GI5). But it only shows the 1, 3 and 5 recordS. And these three records are not on the same height, like going downstairs. What is going on here?

I do not know how to upload the screenshots. And hope my question is clear enough to understand.

Now I solved the displaying problem, all the records can be shown. Because I did not delete the tags in the ListView, I only deleted the content in these tags before.

But these records still are not on the same height, still like going downstairs. So how to solve that problem?

I re-do the step6 to step11, now it works well. But what was happening there?

Hi there,

It sounds like you may have had an empty AlternatingItemTemplate?

Default GridView and DetailsView Surrounding Border

Hi Imar,

Thanks so far so good on chap. 12. I’m at the end and have already begun LINQ to SQL.

However, is there anyway I can get rid of the border tables around the Grid and Details View. It shows in all the browser: IE, Chrome and Firefox. That kind of spoils the feel of the site.

Hope to get your response soonest.

Thanks.

MerryMan.

Default The perceived speed of the AJAX UpdatePanel

CHAP12(Pg.395)

Hello everyone, its been a while I posted. Sorry bout that.

Anyways, I’m curious to know something from chap 1. Does using a partial postback (AJAX) increase the speed of the response time; or its still the same thing, only just being “PERCEIVED” to be faster.

Thanks,

MerryMan.

It depends on what code gets executed. Clearly, the more code you execute, the slower the page will be. However, if you only send back a tiny bit of data, the page can actually load faster because you have less network overhead.

In short: you can't really say something about this in general as there are too many factors influencing the performance. They only way to tell is by measuring the actual performance....

Cheers,

Imar
