Server-Side Programming Overview

Classes and Properties

Following is a table of the most important properties you should be aware of when working with RadGrid.

Property Description
RadGrid.MasterTableView The main grid table - in the general case, when there is no hierarchy, only RadGrid.MasterTableView is rendered. You can think of this table as if it is the grid itself. MasterTableView and generally all table-views in the hierarchy use the style, client behavior and other settings applied to RadGrid , unless explicitly specified otherwise.
GridTableView.DetailTables This collection is used for defining the hierarchical structure of RadGrid .
RadGrid.ClientSettings Set various client-side appearance and behavior options. See RadGridTable client-side API for details.
RadGrid.*Style Properties that control the visual appearance of RadGrid and all tables in the hierarchy.
GridDataTable.*Style properties Properties that control the visual appearance of GridDataTable and all tables in the hierarchy.
GridTableView.ColumnGroups A collection of type GridColumnGroupCollection which holds the multiheaders in the GridTableView
GridTableView.GroupByExpressions Add or remove objects to this collection to set grouping programmatically.
GridTableView.SortExpressions Add or remove objects to this collection to set sorting programmatically.
GridTableView.Columns , GridTableView.AutoGeneratedColumns , GridTableView.RenderColumns Properties to access runtime columns. Columns are set by default in design mode. AutoGeneratedColumns - are automatically generated columns RenderColumns - all columns - columns+ AutoGenerated (if any) + structure columns - expand/collapse and group-splitters

Instead of setting properties for each GridTableView, you can use RadGrid global properties for: PageSize, AllowSorting, AllowPaging, AllowCustomPaging, ShowFooter, ShowHeader, BackColor, BorderColor, PagerStyle. Thus they will be set for each table in the hierarchy, unless specified otherwise.
