Rowtemplate Can't be found by data grid

I am trying to reorganize my app. I moved a form into a new created package.

This form has a datagrid/rowtemplate associated with it. After moving the grid, the rowtemplate
cannot be found.

The design view yields the following error:

Is there a way to reset the path of a rowtemplate?

I solved this issue.

You go to the data grid and click on the data grid drop down:

and select the repeating panel option:

Then you can reset the item_template:
