SSRS: Keep headers visible when scrolling through a paginated report

To prevent row and column labels from scrolling out of view after rendering a paginated report, you can freeze the row or column headings.,

1- On the design surface, click anywhere in the table to display static members, as well as groups, in the grouping pane.

The Row Groups pane displays the hierarchical static and dynamic members for the row groups hierarchy, and the Column groups pane shows a similar display for the column groups hierarchy.

2- On the right side of the grouping pane, click the down arrow, and then click Advanced Mode.

3- Click the static member (row or column) that you want to remain visible while scrolling. The Properties pane displays the Tablix Member properties.

4-In the Properties pane set FixedData to True.

5-Repeat this for as many adjacent members as you want to keep visible while scrolling.

6-Preview the report.
