AJAX :: Use Javascript To Open And Close A Cpe When The CPE Is In A Masterpage?

Sep 2, 2010

does anyone have any working code that uses javascript to open and close a cpe when the CPE is in a masterpage? It seems like the javascript never is able to find the CPE when it is on a master page. I have an DropDownList on the page and when certain items are selected, i want to collapse or expand when others are selected. It seems to work fine on a regular page, but not when it is a page nested in a master page. It is adding a suffix to the CPE and javascript is unable to find it.

State Management :: Best Practise For Caching Objects For A List Of?

Dec 7, 2010

I've created a blog for my first asp.net website. Ive got a blog class as my object. Ive created a number of methods to access my blog articles using LINQ to SQL.

Each method returns a list of objects ready to be used in the appropriate web user control.

In my head i need to cache these lists of objects that are returned, but need to know the best way of approaching this. So i have come up with two possible options

1: Make one method to retrieve all blogs in a list<Blog> and cache this list to be used for all other methods or

2: Cache only the required methods that really need it.

C# - Is There A Visual Studio Load Test Open Source Equivalent - Or Something Close

Jun 2, 2010

In Visual Studio Team Edition there is a load test tool where you can select unit tests, integration tests etc... to form scenarios which are then used in a load test session with different configurations for example varying usage levels.

Looking at for example the NUnit framework, it would be possible to develop a form of such a tool, along with a base load testing code base, but I was interested if anyone knows of any open source project which has has already done a similar thing which could then be of use for this situation and possibly extended?

VS 2008 - Uploading Excel Data To Dataset, Then DataSet To SQL Server?

Jan 18, 2010

What I am thinking is this? Is it possible for me to upload the data from an excel file to dataset of my application first, so that the user can view the data in a gridview to review it first, before the user strike the save button, to save it in the database. So, that in case there is a problem, the gridview will high light all the data with an error. So the user can easily pull out the excel and correct the data before saving it in the database.
