In a Telerik report table, I have a row containing a parent group (Classification) and a second row containing a child group (Detail). Each classification can contain mutiple detail rows. I am attempting to set this up as a drill down, with the detail rows hidden until toggled from the Classification. To do this, I have tried the following:
In the first column cell of the Classification row, I am setting a "Toggle Visibility" action, and setting the Detail group as the toggle target. In the group properties of the Detail group, I have set Visible = False (otherwise the rows are always displayed on the report). When I run the report, only the Classificaiton rows are displayed in the table, with a toggle button in the first cell, as I intended. However, when I click any of the toggle buttons, I get the following error:
An error has occurred while processing Table 'table1':
Index was outside the bounds of the array.
If I shut off the Toggle Visibility action, all rows are displayed in the report, and the error does not occur. Any idea why the toggle feature would be encountering this error?

Everything you described sounds fine. You might have deleted some cells/rows/cols that shouldn't be deleted. Manipulating tables can be tricky. Try to delete the table and create it again in a different manner. It is very important how you achieve the layout of the table. I mean how and in what order you add the rows/cells/groups.
