ASP.NET 2.0: Speed Up Your Site with the Improved View State in ASP.NET 2.0


View state is a wonderful thing. It allows the ASP.NET developer to maintain state for server-side controls that are not form elements.Used judiciously, it can improve the user experience. But in the wrong hands, it can cause your pages to grind to a halt. The release of ASP.NET 2.0 will include a variety of improvements to view state that will make it easier to use and less likely to slow performance.

Cutting Edge: The ASP.NET View State


In ASP. NET pages, the view state represents the state of the page when it was last processed on the server. It's used to build a call context and retain values across two successive requests for the same page.

Sharepoint and IIS/Windows Event Logs in a single view

Hi - I'm coinsidering addng sharepoint log reading capabilities into an application I've built for reading windows and IIS logs (for more info http://logenvy.com). I know there are quite a few applications capable of reading sharepoint logs (a number are listed here http://stackoverflow.com/questions/781179/sharepoint-2007-log-viewer). Does anyone think the capability to analyse windows and IIS logs alongside sharepoint logs would be useful, or have any logging requirements not well met by the current set of tools? I'm especially keen to explore useful/interesting data visualizations on top of data logs.

SSRS 2008 R2 Problem understanding View State Validation steps

Hi, Sorry, but I have some problem understanding this steps. Please help me to understand this.  Pasted from http://technet.microsoft.com/en-us/library/cc281307.aspx?lc=1033 How to Configure View State Validation To run a scale-out deployment on an NLB cluster, you must configure view state validation so that users can view interactive HTML reports. You must do this for the report server and for Report Manager. View state validation is controlled by the ASP.NET. By default, view state validation is enabled and uses the identity of the Web service to perform the validation. However, in an NLB cluster scenario, there are multiple service instances and web service identities that run on different computers. Because the service identity varies for each node, you cannot rely on a single process identity to perform the validation. To work around this issue, you can generate an arbitrary validation key to support view state validation, and then manually configure each report server node to use the same key. You can use any randomly generated hexadecimal sequence. The validation algorithm (such as SHA1) determines how long the hexadecimal sequence must be. Generate a validation key and decryption key by using the autogenerate functionality provided by the .NET Framework. (Well, how to generate Validation key using .Net Framework?) In the end, you must have a singl

Gridview edit mode - What event does enter key call?

I have sort of a very specific problem.  I have a gridview with a few different template columns and a commandfield with the standard "edit" link.  There is no sqldatasource associated with it at all.  In the code, I pull some data from an sql database into a datatable and set the gridview's datasource to be the datatable.This all works fine.  When I hit the "edit" button, the standard textbox shows up where it needs to so that I can edit the data.  The problem is the updating portion.  I have programatically removed the "update" button and left the "cancel" button for design reasons. I want the user to be able to hit "enter" in order to update the data in the data table.  Then, when they're ready, they can click a submit button which will extract the data from the datatable and update the database.I'm having trouble with this 'enter key' business.  When you edit the data and hit "enter" while in edit mode, the page posts back, and the previous values are placed in the gridview.  What event was just  called?  I need a way to take what the user put in and place it in my datatable.  What are my options?Thank you.
