Grid View

  • 8 min to read

The GridView control allows you to display data from a data source in grid. The grid displays data source fields and records as columns and rows in a table.

The ASPxGridView represents the GridView Control on the server side and the ASPxClientGridView represents it on the client side.

Features

Data Binding

The control works only in bound mode. You can bind the grid to any standard data source type: SqlDataSource, ObjectDataSource, XmlDataSource, AccessDataSource, and SiteMapDataSource.

Use the KeyFieldName property to set a data source's key field name. The DataSourceID and DataSource specify the data source's ID and data source object.

Database Server Mode

The grid supports database server mode. In this mode, the grid loads only required items to the server memory and implements data-aware operations (for example, filtering) at the database level.

Unbound Columns

The grid control supports unbound columns that are not bound to any data source field. Use the CustomUnboundColumnData event or specify the UnboundExpression property to populate an unbound column with data.

Move Columns

The grid control supports drag-and-drop functionality that allows you to move a column to the desired position among other columns. You can use the AllowDragDrop property to allow end users to move all grid columns or a column's Settings.AllowDragDrop property to enable drag and drop for an individual column.

Header and Data Cell Bands

The grid control enables you to organize columns in logical groups (bands) and display them in multiple rows. Header bands (GridViewBandColumn) organize grid columns into logical groups and display hierarchical multi-row headers.

See demo

Data cell bands (Columns) allow you to display a data record hierarchically. Specify the CellRowSpan and CellRowSpan properties to arrange a column header and data cells in a data cell band layout.

Fixed Columns

The grid allows you to fix columns on the left side and display these columns onscreen when the columns' total width exceeds the grid width. Enable the horizontal scrolling (HorizontalScrollBarMode) and set a column's FixedStyle property to Left to fix the column.
