# Columns

RadGridView currently supports two main column types:

* **Data columns:**  all columns in this list inherit **GridViewDataColumn** class.

* **Structure columns:** all columns, which are added by **RadGridView** automatically to facilitate some functionality are called structure columns (e.g. expand/collapse the hierarchy)

## Data columns

The following are the available **GridViewDataColumn** descendants column types used in **RadGridView**:

## Structure Columns

### GridViewIndentColumn

This column appears when the grid data is grouped or has a hierarchical structure. The GridViewIndentColumn facilitates expand and collapse functionality. The expand column is always placed in front of all other grid content columns and can not be moved.

### GridViewRowHeaderColumn

This column facilitates row resizing. When you move the cursor to an line in this column, the cursor changes to an arrow and you can resize the respective row.
