How to get the parent Frame from the child element.

Posted By:      Posted Date: September 19, 2010    Points: 0   Category :WPF

Hi, All,


I have a Frame element in my main window, and I used its "Source" property to navigate to another "Page".

However, I could not find the way to get the Frame object again within the "Page".(Parent property just gave me null)

Could anyone please show me some solution?

Thanks in advance.

Parent-Child Dimension where the top most element has an ID of zero instead of one


I have a parent-child hiearchy where, when I browse it, the top most element is a sibling of the first child instead of the parent of the first child. I seemed to have narrowed down the behavior to the fact that the top most element has an id of 0 instead of 1. When the top most element id is 1, I don't get this behavior.

Is there an attribute property that I may have misconfigured to cause this behavior?

 Consider the following table:

ItemID  ParentItemID  Description
--------  ------------       -----------
0          null                 Top Node
1          0                     Child Node
2          1                     Grandchild node

 I get the following in the Browser tab for the dimension

- All Test Nodes
  - Child Node
    - Grandchild Node
  - Top Node

Notice that the "Top Node" is

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

Error - "Specified element is already the logical child of another element. Disconnect it first."

What I have is a Grid with each cell containing its own canvas.  I have a UserControl (uc) that I want to be able to drag/drop to other cells within grid.  I was able to get my drag/drop of the uc working except for the error in the subject.  On a drag/drop of a uc, I determine the canvas the drag started in, get a reference to the uc, clear the original canvas's children and add the uc to the new canvas.  The wierd thing about this error is that it is not entirely consistent.  Sometimes, I can drag the uc around to three or four different cells before receiving the error.  I have read multiple posts about this error but I don't seem to be able 'disconnect' the uc from its original logical parent.  Help is appreciated.

IsVisibleChanged not firing when element is in collapsed parent element

Using the code below, it is possible to change the child grid's visibility in code-behind. However, as long as the parent grid is collapsed, the IsVisibleChanged event will not fire for the child grid even though its visibility actually changes. Is this by design, or am I missing something? I want to be able to change the parent grid's visibility when the child grid's visibility changes, and under these circumstances I have to work around the issue with the non-firing event. <Grid x:Name="LayoutRoot">   <Grid x:Name="grdOuterGrid" Visibility="Collapsed">     <Grid x:Name="grdInnerGrid" IsVisibleChanged="grdInnerGrid_IsVisibleChanged" />   </Grid> </Grid>
