AX2009EPDevCookbook.docx

Suppose you are using the page template with 2 zones (Left & Right) and you want to set the right zone to be with 20%, EP provides a API that you can use to set the width of the WebPart zone in terms of Percentages.

Just add the following code to your user control –

protected override void OnPreRender(EventArgs e)

    {

        base.OnPreRender(e);

        //Add style to get 80/20 column widths for the left/right web part zones

        Microsoft.Dynamics.Framework.Portal.UI.StyleRegisterHelper.SetWebPartZoneWidths(this.Page, Unit.Percentage(80), Unit.Percentage(20));

    }

In AX 2009, EP grid control comes with an advanced filter. Here is a code to persist the filter condition the user last entered in a page for that user, so that later when the user comes back to the same page the last filter is applied and user didn’t have to reenter then.

This code sample assumes a dataset with the name “EPSalesTableList” which contains the datasource “SalesTable”

 (1) First override the pack method of the dataset ( EPSalesTableList in this example) in AOT

public container pack()
{

container ret;
SysLastValue sysLastValue;

formdatasource filterDataSource;
;

filterDataSource = SalesTable_ds; // Put your datasource name

    ttsbegin;
       // Delete last saved query for the current dataset
    delete_from sysLastValue
        where sysLastValue.Company      == curext()
           && sysLastValue.UserId       == curuserid()
           && sysLastValue.RecordType   == UtilElementType::DataSet
           && sysLastValue.ElementName  == filterDataSource.name()
           && sysLastValue.DesignName   == filterDataSource.name();

    // If there is a new queryRun() object then serialize and save it
    // in the sys last value table
    // Put your datasource name
   
    if (filterDataSource.queryRun())
   {
   
        sysLastValue.RecId = 0;
        sysLastValue.Company      = curext();
        sysLastValue.UserId       = curuserid();
        sysLastValue.RecordType   = UtilElementType::DataSet;
        sysLastValue.ElementName  = filterDataSource.name();
        sysLastValue.DesignName   = filterDataSource.name();
        sysLastValue.value = SysQuery::packRangeAndSortorder(filterDataSource.queryRun().query());   
        sysLastValue.insert();
    }
    ttscommit;

    ret = super();

    return ret;

}

(2) Second override the init method of the datasource ( SalesTable in this example) within that dataset in AOT

 Make sure you replace the datasourcename variable filterDataSource in the pack method with your datasource name.Save the changes, refresh AOD and now go to the page that is using this dataset and enter some filter condition & apply. Close the browser and reopen the page. Now you should see that the filter that you last applied before the browser was closed is still applied in this page.

Arif Kureshy, who is the dev manager for EP came out with this code snippet. So thanks to him for providing this sample code.

Session 1 : EP Development ( repeated) – 28^th April by Diwakar Bedekar ,  Microsoft

Here is another opportunity for you to join a developer oriented deep-dive technical session on Enterprise portal for Microsoft Dynamics AX 2009. We will cover how to build and customize EP pages, user controls for lists/tasks/wizards, and common programming tasks. You are invited to participate in this virtual meeting bringing your experiences with Dynamics AX to the table, your questions and feedback, too. The discussion will be facilitated by our key R&D folks responsible for this part of the solution.

Please use the LiveMeeting invitation details below to join the meeting. If you have any questions about this meeting or others like this, please send us an email at dynresch@microsoft.com.

Session 2 : EP Deployment ( repeated) – 04^th May by Mey Meenakshisundaram,  Microsoft

See you all at Convergence 2009.

But there may be scenarios where you want to use your own controls to filter the grid or the underlying DataSet. The EP framework provides the following classes to do this –

- FilterObject

- ConditionType

Let’s look at how we can do the filtering from code behind.

1. Add a Filter to list only the Customer whose name that starts with “Light”

2. Using Between operator – Between operator is a special case. There are two ways to use the Between operator -

a. Using – value..value

b. Using – valueCollection class

3. How do I use more than one condition -

4. Filter on a date – which format should a date be in? Is there a single format which can always be used?

When using the Filter control available in EP Grid, the date will be in user regional settings. But when using from the code behind, the IIS server’s regional settings will be applicable. So if the regional settings on the IIS are ‘MM/DD/YYYY’ the date value must be specified in ‘MM/DD/YYYY’ format.

Enterprise Portal in AX 2009, supports sharing of code using a dummy User Control (we call this a dummy user control as it doesn’t have any UI and contains only reusable functions). Create a User control and add all the common reusable code into this dummy user control and then include it into your other user controls where you want to use this common code.

For the sake of simplicity, I am going to show how you can display the current logged in User’s information in multiple user controls by sharing the code.

Let's assume that you have two user controls that need the Current Logged in User's name. To achieve this I will be creating a User Control called - MyCommonCode.ascx and two controls that will be using the common code - MyUserControl1 & MyUserContorl2.

Creating the User Control to store the common code

So the first step is to open Visual Studio and to create a Dynamics AX Web Project. In Visual Studio select \New\New Web Site from the File menu. In the subsequent New Web Site dialog a Dynamics AX Web Project should be located under My Templates. The dialog should look something like the following screen shot.

After clicking OK a project is created in Visual Studio that contains amongst other things a node called AxUserControl.ascx. Right click on the AXUserControl.ascx node and rename it to MyCommonCode.ascx.

Go to the Code behind file for this user control and add the following static methods to get the GetCurrentLoggedInUser() method.

Save the File.

Create Controls to use the common code

To add new user controls to the web site project, right-click on the Project and select Add New Item.

Repeat to above steps to add a second user control.

Open the MyUserControl1.ascx and add the following markup -

The First line is the most important line as it enables the code sharing.  The rest of the markup is just standard ASP.NET markup. We are adding a label to display the User name.

Go to the Code behind for this user control and add the following highlighted code to the Page_Load event.

Repeat the same for the other user control.

To add the User Controls to the AOT right-click on the user controls and select "Add to AOT".  The user controls will be saves in AOT under \Web\Web Files\Web Controls and in addition they will be deployed to the web server where the EP development site is deployed.

Now go to SharePoint create a new page and add the two user controls - MyUserControl1.ascx & MyUserControl2.ascx and you will see the Current Logged in user name displayed in both the user controls.

Anytime you want to share some common code across user controls, just add your methods to the Common user control and include the user control (using the ASP.NET Register directive) where you want to use the common code.
