This sample demonstrates frozen columns. Freezing keeps key columns fixed while horizontally scrolling to improve comparison across wide tables.
Configure freezing using the column Freeze property. Enable runtime repositioning of the freeze line by setting AllowFreezeLineMoving to true.
In this demo, Task ID is frozen left and Approved is frozen right while scrolling.
See the frozen rows and columns documentation for details.
