passing a primary key value from a parent to a child viewmodel

Posted By:      Posted Date: September 15, 2010    Points: 0   Category :WPF
I have a view (parent), a user control (child), and each have their own viewmodels. I need to tell the user control's view model what the parent's viewmodel primary key (PK) is. I am creating an instance of the child's viewmodel in the parent viewmodel, but I can't seem to get the child viewmodel to bind to the parent's PK value. Parent viewmodel:         private void Initialize()         {    CurrentParent currentParent;        // set the datacontext of the parent             if (NavigationActions.DataContext != null)             {                 CurrentParent = (ParentDto)NavigationActions.DataContext;             }             else             {                 CurrentParent = new ParentDto();             }        // create an instance of the child's view

How to show primary key of Parent-Child hierarchy

I have dimesion with ragged Parent-Child hierarchy. For instance organizational structure of a company. Commonly the hierarchy shows names of hierarchy items but now I need to create MDX query where result on axis 1 will be ID (primary key of dimesion) of item and name of item, but main is to show id.

{[Product].[MetaGroupHierarchy].children} ON 1

With mentioned MDX query the result is :


And I would like to have:
ID1, name1
ID2, name2
ID3, name3



I do not know how to construct MDX query in this case.  Because main dimesion key has to have NameColumn property set to field with name of item.

WPF Passing a value from parent to a child 'page' hosted in a frame.



I have - what might look like an obvious question - for me it is a headache.

Some background info:

In a WPF Window, I have placed a frame. A Ribbon button in the WPF window executes NavigationServices as you can see below. Mind there is no navigation History (back/Forward).

I have a variable called datasetId in both the parent and child. it gets computed in the child and needs to be passed to the parent...



Any suggestions?


Thanks for any help in advance..



SSIS Parent/Child Package variable passing



I have having trouble getting my hands around how to retrieve variables from a parent package.  I read about the Environment variables and Configuration File at the parent package level and the Parent Package variable at the child level.

Here are my questions:

1.  Can you only store/retrieve 1 variable in a config file at a time?

2.  Does the child package have to define the variables and if so, do they have to be the same names as the parent package?

This seems so more more complex then the DTS2000 way of passing variables to and from packages.

Any help would be appreciated.

Thanks in advance,

Passing Primary Key to User Control to Display Record Detail


I'm building a user control to display detail information on a parent record. The user control will be displayed via an Ajax Modal Popup. The user control works and is displayed when expected. The problem that I'm having is that I'm not able to pass in the primary key for the parent. The control is displayed via the _ItemCommand event of a Repeater. In the markup for the user control, I explicity set the ContactId to 0 to avoid an error when the control loads (its still underdevelopment, eventually that I'll check if the value is valid).

I was assuming that I could change the property in the _ItemCommand event, but obviously its not working.

In the Page_Load event this code successfully sets the ContactId property of the control. The _ItemCommand event appears to set the value. However when I set a test label on the user control to the Me.ContactId, its showing '0' as if it was never passed in.

        UserControlContactDetail.ContactId = "1462"
        test.Text = UserControlContactDetail.ContactId

    Protected Sub RepeaterDirectory_ItemCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.RepeaterCommandEventArgs) Handles RepeaterDirectory.ItemCommand

InfoPath and Access - two parent tables and one child table


Hi there,

I'm trying to link an InfoPath form to an Access database, I want to connect the InfoPath form to 3 tables in the Access database but InfoPath will only recognise parent-child relationships in a series (e.g. the "Company" table is the parent to the "Customer" table, which is again parent to the "Orders" table)

I need to have two parent tables and one child table, though (e.g. "Customer" is parent to "Orders", but "Inventory_Item" is also parent to "Orders"). Is there any way to establish this in InfoPath? I'm using Windows XP, InfoPath 2007 and Access 2007.

Cheers, Patrick
