Remarks

The LinqServerModeSource component allows you to bind the GridControl or PivotGridControl to an IQueryable query provider, and enable server mode. To do this, follow the steps listed below:

  • specify the key field name for objects retrieved from a data source using the LinqServerModeSource.KeyExpression property:

    linqServerModeSource1.KeyExpression = "CustomerID";
    
  • specify the queryable source via the LinqServerModeSource.QueryableSource property. This property should be set in code:

    public Form1() {
        InitializeComponent();
        linqServerModeSource1.QueryableSource = new DataClasses1DataContext().Customers;
    }
    
  • bind the control to the LinqServerModeSource component.

Note

The LinqServerModeSource is a read-only data source.
