Double relation to same DataTable with LINQ Reporting Engine

Hello,
I need to manage two DataTables which are connected with two different relations, but I cannot find a way to do this.

I created a simple example with a TextBlock class/table which has two properties (ForeColor and BackColor) which point to the same CustomColor class/table.

With custom classes you can simply use this syntax:

<<foreach [textBlock in textBlocks]>> <<[ForeColor.Name]>> on <<[BackColor.Name]>> <</foreach>>

With DataTables I tried with several options, but none of them worked.

  1. Obviously you cannot use TableName (as with single relations) because it would be ambiguous:

<<foreach [textBlock in TextBlocks]>> Ambiguous: <<[CustomColors.Name]>> <</foreach>>

  1. Using RelationName:

<<foreach [textBlock in TextBlocks]>> <<[ForeColor.Name]>> on <<[BackColor.Name]>> <</foreach>>

  1. Using GetParentRow(“RelationName”):

<<foreach [textBlock in TextBlocks]>> <<[GetParentRow("ForeColor").Name]>> on <<[GetParentRow("BackColor").Name]>> <</foreach>>

  1. Using GetParentRows(“RelationName”):

<<foreach [textBlock in TextBlocks]>> <<[GetParentRows("ForeColor").Name]>> on <<[GetParentRows("BackColor").Name]>> <</foreach>>

  1. Using GetChildRows(“RelationName”):

<<foreach [textBlock in TextBlocks]>> <<[GetChildRows("ForeColor").Name]>> on <<[GetChildRows("BackColor").Name]>> <</foreach>>

Is there a solution to this?
Probably it would be nice if you could use the RelationName to navigate to other tables.

Hello,
do you have an estimated time for this feature to be implemented?
Unfortunately we have may of these cases in our DB.

Do you know if there is an alternative solution we can use in the meanwhile?
For example, do you know if it is possible to use DataViews to simulate that the two properties point to 2 different tables (also if it is the same one with 2 views)? That is (following the example) make “ForeColor” and “BackColor” be 2 DataViews of table “CustomColors”, then link “TextBlock” with the 2 DataViews. Can a DataRelation be used with DataViews instead of DataTables?

Thank you for your help.

Thank you very much for the rapid implementation!

I noticed that the new version come out and I tried it (although there has been no notification from the forum thread).

It works as expected using relation names.
