## Row

Each row in **RadGridView** is represented by **GridRowElement** class.

## HeaderRow

The header element is represented by **GridHeaderRowElement** class.

## NewRow

Depending on the value of **GridViewTemplate.AddNewRowPosition** property, the new row element appears below the header row or after the data rows.

## FilteringRow

*FilteringRow* appears automatically when you have [Filtering](https://www.telerik.com/products/winforms/documentation/controls/gridview/features/filtering/basic-filtering) enabled by **EnableFiltering** or **GridViewTemplate.EnableFiltering** properties.

## GridViewIndentColumn

This column appears when the grid data is grouped or there is a hierarchical structure to facilitate the expand/collapse functionality. The expand column is always placed in front of all other grid content columns and cannot be moved.

## GridViewDataColumn

Displays a column bound to a field in a data source.

## MasterTemplate

**MasterTemplate** is the top most **GridViewTemplate** in the hierarchical structure which stores the columns and rows at the root grid level. It contains all inner **GridViewTemplates**(**GridViewTemplate.Templates** collection). When there is no hierarchical structure, only the **MasterTemplate** is displayed.

## GridViewTemplate

**GridViewTemplate** is a basic class containing settings for a single level of the hierarchical structure.

## GroupPanel

When you want to enable the group-by functionality for the end-user, you need to set **RadGridView\.GroupingEnabled** to *true* and **GridViewTemplate.EnableGrouping**.  If you want to prevent the end-user to drag column header into the **GroupPanel,**  set **GridViewTemplate.AllowDragToGroup** to *false*. **RadGridView\.ShowGroupPanel** shows/hides the group panel. You can access the group panel using **RadGridView\.GridElement.HeaderElement.GroupPanel** property.
