You can highlight the selected stap of the wizard control by editing the SideBarTemplate within the asp:Wizard control.

The ItemTemplate and the SelectedItemTemplate need to have a Button with ID SideBarButton.

In this article we're going to create a usercontrol with a button. Place this usercontrol on a page and handle the clickEvent on that page.

Step 1, the UserControl

Create a usercontrol with a button called  'clickMeButton'.

In the codebehind of your UserControl define a delegate.

Then create a public EvenHandler.

Now add a click event to the button and on the click event fire tje ButtonClickedEvent.

And the usercontrol is finished, now create a page to use the usercontrol.

Step 2, the Page

Create a new page. Add the usercontrol to the page, in the codebehind (Page_Load) attach your page to the ButtonClickedEvent.

Press tab twice to generate the following Method.

Lets implement some basic logic to the event to test if the event is working

Step3, the result

Here is the result after the user clicked the button within the usercontrol. As aspect-ed the Button Clicked text is shown.

With ADO.Net Data Service you can add parameters in the Querystring. The following parameters are recognized:

• expand 
• orderby 
• skip 
• top 
• filter

So if your request for all products was AdventureWorks.svc/Product you can add parameters like this AdventureWorks.svc/Product?$[paramatername]=expression

For the examples I use the Product table of the Adventureworks database.

Filter

Filter allows you to filter the selected result based on a expression. The expression has two types of operators: logical, and arithmetic.

The logical operators are:

• eq  (==) 
• ne  (!=)
• gt  (<)
• gteq  (<=)
• lt  (>)
• lteq  (>=)
• and  (&&)
• or  (||)
• not  (!)

The arithmetic operators are:

• add  (Addition)
• sub  (Subtraction)
• mul (Multiplication)
• div  (Division)
• mod  (Modulus)

Example
Let's say I want to have the product with the value 534 in the ProductId column.

Result

Expand

Example
Let's say we want to use the ProductReviews of the product in our application. To do this we need to load the ProductReviews values on request, we can achieve this with the expand paramater.

To get a clear view of what the expand parameter does I included the filter funtion on ProductId 534 so we can compare the results.

Result

Skip

Example all productreviews

Result
 

Example skip productreviews

Result
Only the last two ProductReview objects get returned.
 

Top

Example

Result
This will return the first three product reviews.

Orderby

Example

Result
This will sort the results by the column 'Name'.

You can also define build a more complex order clause by combining columns in a comma-delimited list, example:

Result
Only the product with ProductID values equeals 534 will be returned.

Combining attributes

You can combine the attributes. You can do this by creating a URL and seperating the attibutes with a '&', example;
AdventureWorks.svc/Product?$[paramatername]=expression&[paramatername]=expression

Example

I finished building a Google CSE platform and deployed multiple .Net related searchenginges. 

• dotNetSearch.Net
  
• SilverlightSearch.Net
  
• SharepointSearch.Net (with Bas)

 Let me know If you have good ideas or sites for the searchengines? 

More will follow.

For dotNetSearch.net I needed to cache the RSS feed (on the right). I did this with the .Net Cache namespace.

In this examle I add the RSSFeed content as object in the cache and use the url of the RSS feed as Key. The Cache will expire (and cleared) after 15 minutes.

When deploying a project to a internal test server I got the following error:

The definition of the report 'Main Report' is invalid.
An unexpected error occurred in Report Processing.
Could not load file or assembly 'Microsoft.ReportViewer.ProcessingObjectModel, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified. 

Fix this by adding a reference to ProcessingObjecdtModel.dll in you project. You can find the ProcessingObjecdtModel.dll in the GAC. The problem with the GAC is that you can't copy the .dll from the GAC using Windows Explorer. But you can copy the DLL with Command Prompt (cmd.exe).

To do this:

This action will look like this:

Copy the Microsoft.ReportViewer.ProcessingObjectModel.dll to your Bin folder or at a reference to the assembly.

After installing and playing with the Asp.Net Charting control I decided to use it for a customer. When integrating the control to the project I got the following error

"Error executing child request for ChartImg.axd"

This error occurred because I did not update my web.config file. You have to add the following appSettingkey, httpHandler and handler.

Enjoy charting,
