Gets or sets the name of the scope (data region or group) in which to evaluate the UserSort.SortExpression. If omitted, the expression will be evaluated and the sort will be performed independently in each detail scope within the UserSort.SortTarget. Must be a scope that is equal to or contained within the current scope. If the Textbox has no current scope (in other words, it is not contained in any data region), SortExpressionScope must be equal to or contained within the UserSort.SortTarget. Cannot be a detail scope (that is, a group with no group expressions). The data set for SortExpressionScope must be the same as the data set for the UserSort.SortTarget. Sorting takes place within the group containing the SortExpressionScope. For example: In a Tablix with a country group and a city group with UserSort on each header and UserSort.SortExpressionScope of the corresponding group, the country sort will sort the country groups within the tablix and the city sort will sort the city groups within each country group (without rearranging the country groups).
