Hi,
So far as I know, please refer to the steps below:
- Right-click the whole matrix control, and then select Properties.
- Switch to Groups tab, click Add button to add another Row group, in the expression textbox, please select groupedcolumn1 datafield(This is very important)
- Then click the new row group, then click Up button to move it to the top1 location.
- Click OK
- Switch to the report’s design surface, then type in the expression =Runningvalue(Fields!GroupColumn1Name.Value,countdistinct,"MatrixName") in the textbox created in step3.
These steps come from the link below:
