Hello Telerik Support Team,
We are experiencing a scrolling issue in **Telerik PivotGrid for Blazor (v12)** when both vertical and horizontal scrollbars are present.
**Issue Summary**
When the PivotGrid contains enough expanded data to require both vertical and horizontal scrolling, interacting with one scrollbar causes the grid to unexpectedly reset the other scroll position (jumping back to the top or left-most column).
**Steps to Reproduce**
e.g.: https://demos.telerik.com/blazor-ui/pivotgrid/overview
1. Bind the PivotGrid with a large dataset.
2. Expand a column hierarchy (e.g., Year → Months) to generate horizontal scrolling.
3. Expand multiple row groups (some near the top and some further down) to generate vertical scrolling.
4. Scroll fully to the **right**.
5. Attempt to scroll **down** using the vertical scrollbar or mouse wheel.
* The grid scrolls down, but the horizontal position resets to the first column.
6. Scroll to the **bottom**.
7. Attempt to scroll **right** using the horizontal scrollbar.
* The grid scrolls right, but the vertical position resets to the top.
**Actual Behavior**
Scrolling in one direction causes the PivotGrid to reset the scroll position in the other direction.
**Expected Behavior**
Vertical and horizontal scroll positions should remain independent. Scrolling in one direction should not reset the other.
This occurs consistently when multiple row and column groups are expanded and both scrollbars are active.
Please let us know if additional configuration details or a sample project would help.
