Hi a have problems with FindRow.

In my Test Application I have a DataSet with 3 Tables:
Company --> Car --> CarModel. The 3 Tables have also a DataSet Relation.

I bind the Virtual Tree DataSource to myDS.Company

In the DataBinding Tab of the VirtualTree Designer i make 3 DataRowBindings and set the Child/Parent Relation to the DataSet Relation.

When I call myVirtaulTree.FindRow(myDS.Car[1]) the return Value of the Method is null.

What I make wrong?

Thanks and best Regards
Giuseppe

ok. I found the problem ... I have to use the DataRowView instead of the DataRow.

it's also possible to use a DataRow?

thanks

No unfortunately when working with Datasets you have to use DataRowViews - since this is the type of object returned by the DataView as its children. Microsoft don't make it particularly easy to manage the conversion from a DataRow to the corresponding DataRowView - for this reason we supply a static method (GetDataRowView) in DataRowRowBinding that you can use to locate the DataRowView in the DefaultView of a table that corresponds to a given DataRow.
