Common Cell Template Tasks

This sample shows how you can accomplish two of the most common tasks for cell templates: conditional formatting and images.

All versions of the sample show how you can accomplish these tasks using the Column.cellTemplate property.

The framework-specific versions also show how you can do the same thing using cell template directives, which are more powerful but slightly more complex.
