MultiRow offers many advanced features. These features are listed below:

*   **Multiple Layout Definition**<br />MultiRow allows you to set the [LayoutDefinition](/componentone/api/mvc/online-mvc/dotnet-framework-api/C1.Web.Mvc.MultiRow/C1.Web.Mvc.MultiRow.MultiRow-1.LayoutDefinition.html) property, which takes an object that describes the layout of the grid rows and cells. The LayoutDefinition property specifies the layout of the cells in the MultiRow control.<br /><br />
*   **Fully Expanded Column Headers**<br />MultiRow allows you to set the [CollapsedHeaders](/componentone/api/mvc/online-mvc/dotnet-framework-api/C1.Web.Mvc.MultiRow/C1.Web.Mvc.MultiRow.MultiRow-1.CollapsedHeaders.html) property to true which enables the grid to show a single row of column headers containing the group names. Setting it to false cause it to show a group of rows with the same layout as the data, and column names in the cells.<br /><br />
*   **Collapsible Column Headers**<br />MultiRow allows you to set the [CollapsedHeaders](/componentone/api/mvc/online-mvc/dotnet-framework-api/C1.Web.Mvc.MultiRow/C1.Web.Mvc.MultiRow.MultiRow-1.CollapsedHeaders.html) property to true which allows you to collapse the column headers to a single line, showing only the group names rather than individual cells. This saves space at the expense of having individual cell headers.<br /><br />
*   **Multiple Group Header Rows**<br />MultiRow provides [MultiRowGroupHeaders](/componentone/api/mvc/online-mvc/dotnet-framework-api/C1.Web.Mvc.MultiRow/C1.Web.Mvc.MultiRow.MultiRow-1.MultiRowGroupHeaders.html) property which allows you to determine whether group headers should have multiple row instead of single header row. This can be used in a scenario where you want to display aggregate values in the group header.<br /><br />
*   **FlexGrid Features**<br />MultiRow extends from the [FlexGrid](/componentone/api/mvc/online-mvc/dotnet-framework-api/C1.Web.Mvc/C1.Web.Mvc.FlexGrid-1.html) class. It is a full-featured grid just like the FlexGrid control, providing various features including several selection modes, sorting, filtering, row and column freezing, custom cells, data mapping and more.
