I am trying to Validate fields in a details view. But when I fire the save method, even if the fields are invalid the validation text/summary will not be displayed. It will only disaply if i cancel the save event in the pre update event. But I don't want to do this.

Any ideas on using validation with a DetailsView / GridView

cheers

Set a breakpoint in that page init method, and see what's going wrong.

Exam certificacion question
Ive seen this question in more than one simulator with C,D and also B,D or even just B as answers, what do you think would be the correct one and why?

You create a Web Form. You need to add controls that use adaptive rendering to display content. The type of content rendered must depend on the device that is requesting the page. What are two possible ways to achieve this goal? (Each correct answer presents a complete solution. Choose two.)

A. Add custom controls that emit XHTML to the Web Form.
B. Add custom controls that emit WML to the Web Form.
C. Add mobile controls to the Web Form.
D. Add Web server controls to the Web Form.

Answer: C, D

I guess "D" is the one. Webserver control knows how to render for different requesting browsers. If you add mobile controls, it won't work with normal browsers AFAIK.

Hi I have a page that brings the all no.of users, visitors, groups, documents in the site from database via webservice. The results from my webservice and database are fast locally and on the remote machine but when I call my webservice from my code its taking more time (I calculated the start and end debugging time with Environment.TickCount;) and it returns the time like 2187 for the first time, 1172 second time call and so on decreases the time. Also it takes time from the javascript call to my page call (means entering my code-behind code, to call the web service), I dont understand whats happening in between that time.

Any Ideas please!!!

Why do you want to add it to the webconfig, why not just the one page where it is needed?

Hi,

I have a datagrid to which a database table called "employee" need to be binded. there are 9999 records in my table.while i bind the datagrid it takes several minutes for it to load...

is there any other ways to improve its performance so that i can reduce the time of loading the page??

plz reply ASAP...

Thanx in advance,

zari

Well, one common sense UI decision would be to not have 10,000 records in your grid.

The datagrid is designed for common UI tasks. If you need to load 10,000 records, you need to find a commercial grid that deals with this ( essentially by only loading small subsets of that data at a time )

This seems to be a common question in this forum.
Why not cut down the number of records by filtering them, maybe on search criteria by a user.This way not so many are being binded to a datagrid
Other then that follow the advice of CG
