Appearance and Conditional Formatting.To choose the data presentation format, set the MainView property to any of the following objects:.

If you bind the grid to a table with master-detail relationships, the View you assign to the MainView property presents data from the master table, while the detail Views, which you can specify with the LevelTree collection, present data from the child tables.

View this topic on docs. To choose the data presentation format, set the MainView property to any of the following objects: GridView - Displays data in a tabular form. BandedGridView - Displays data in a tabular form and allows grouping of columns into bands. AdvBandedGridView - Displays data in a tabular form, allows grouping columns into bands and supports complex data cell arrangements.

CardView - Presents data records as cards, arranged down and then across. Card fields are always arranged in a single column. LayoutView - Presents records as cards, which can be displayed in one or multiple columns, one or multiple rows, in an ellipse carousel mode or a single card at a time. Supports complex card field layouts, built-in groups, tabbed groups and labels. This View provides the advanced field positioning feature, which helps you arrange fields relative to other fields, specify absolute or relative field display bounds, etc.

The following are main properties the Data Grid provides: DataSource and DataMember - Use these properties to bind the control to a data source. LevelTree - Allows you to associate master-detail relationships with Views.

The figure below illustrates how to invoke the wizard for the GridControl. The first wizard page asks you to choose the technology you would like to use. The message box that will appear tells you that the SqlDataSource component will be added automatically. If you need to modify the data source later, you can use the SqlDataSource 's smart-tag.

For now, the Data Source Configuration Wizard will automatically open the required dialog. Configuration Wizzard automatically adds the required piece of code to your project and you can run the application to see the result. Note The following approach assumes manually adding and customizing the SqlDataSource component mentioned above. Other than that, the two approaches are identical. So unless you have a strong necessity to use this approach, we recommend using the Data Source Configuration Wizard instead.

To invoke this wizard manually, click the 'Configure Connection' link within the component's smart-tag. Follow these tutorials to set up the connection. You now have a SqlDataSource component bound to the required data. Next, set this component as the grid control's data source the GridControl.

DataSource property and the Products table as its data member the GridControl. DataMember property. The final step is calling the SqlDataSource.

FillAsync method to retrieve your data. In the code below, the method is called on the FormLoad event. In this example, a CustomSqlQuery is used. To learn about supported database engines, see the inheritance hierarchy of the DataConnectionParametersBase. Note that specific controls may need additional customization after the control is bound to a data source.

DataMember Property. DataSource Property. DefaultView Property.Updates the MainView to reflect changes made to a data source. The method reloads all records from the grid's associated data source for this purpose. Note that calling the method makes sense only when the bound data source doesn't support the System. IBindingList interface. Otherwise, the control will automatically update itself.

Changes made to existing rows are not recognized, unless the data source IBindingList object implements the System. INotifyPropertyChanged interface. To reload data within detail Views, use the ColumnView. RefreshData method. Do not call the RefreshDataSource method if you only need to update certain rows, since this method forces the entire grid to re-draw and negatively affects the application performance.

In this scenario, utilize the ColumnView. RefreshRow method instead. General Information WinForms Controls. XtraWizard ASP.

AccessibleNotifyClients Method.The quickest way to set up a new data source is to utilize the Data Source Configuration Wizard. Invoke this dialog through the Data Grid smart tag or by clicking the icon in the Grid's bottom left corner. The UnboundSource component allows you to mix different data source types or add virtual rows to a bound Data Grid.

For code-first data sources, it is possible to mark data class properties with Data Annotation Attributes to pre-customize a Grid e.

If you already have a data source ready, use the Data Grid smart tag to select this source in the "Choose Data Source" editor. In code, assign a valid source to the GridControl. DataSource property. Once you have chosen a data source for the first time, the Data Grid automatically generates all required columns.

Should you choose another data source later, previously created columns will remain and you'll need to update them manually. For most data source types, the Data Grid allows end-users to edit data at runtime, but these changes are not automatically saved to an underlying source.

The traditional approach to customize grid columns or bind them to data assumes that you will be accessing columns using their string field names. If for any reason, it is impossible to populate grid columns at runtime or you need custom logic to obtain column settings, you can use fluent API instead.

In this approach, the Visual Studio's IntelliSense allows you to observe all the data source properties and bind the required fields to grid columns.

This approach creates a fail-safe code when modifying the data source structure e. The traditional approach can ignore such errors in certain cases, creating 'dead' code that is hard to detect. Now, you can call the ColumnView. With method to add and configure columns. The following code snippet illustrates an example. With fluent API, you are also able to obtain existing columns and tweak their settings.

To do so, use the ColumnView. GetColumnViewSettings method. For instance, the following code is the GridView. RowCellStyle event handler that identifies the column related to the row cell and fills it in red if the column is 'Phone'. General Information WinForms Controls. View this topic on docs. The Wizard guides you through the binding process to the following supported sources. XML Data Custom data with no strongly typed data set available The UnboundSource component allows you to mix different data source types or add virtual rows to a bound Data Grid.
