在NetAdvantage for .NET中我們可以用Text和ImageUrl屬性來分別將指標的等待消息配置為顯示文本或圖像。如果兩個屬性都設置了，那么Text屬性優先于ImageUrl屬性。在設計和運行時，我們都可以在控制層配置AJAX指示燈。

代碼如下：

VB

Me.WebDataGrid1.AjaxIndicator.Enabled = Infragistics.Web.UI.DefaultableBoolean.[True]
Me.WebDataGrid1.AjaxIndicator.Text = "Ajax Call Wait Indicator"
Me.WebDataGrid1.AjaxIndicator.Location = Infragistics.Web.UI.RelativeLocation.AboveCenter

' Set the location of the Ajax Indicator specific to the control.
Me.WebDataGrid1.AjaxIndicator.RelativeToControl = Infragistics.Web.UI.DefaultableBoolean.[True]

' Blocks or Grey out the control during Ajax call
Me.WebDataGrid1.AjaxIndicator.BlockArea = Infragistics.Web.UI.AjaxIndicatorBlockArea.Control

C#

this.WebDataGrid1.AjaxIndicator.Enabled = Infragistics.Web.UI.DefaultableBoolean.True;
this.WebDataGrid1.AjaxIndicator.Text = "Ajax Call Wait Indicator";
this.WebDataGrid1.AjaxIndicator.Location = Infragistics.Web.UI.RelativeLocation.AboveCenter;

// Set the location of the Ajax Indicator specific to the control.
this.WebDataGrid1.AjaxIndicator.RelativeToControl = Infragistics.Web.UI.DefaultableBoolean.True;

// Blocks or Grey out the control during Ajax call
this.WebDataGrid1.AjaxIndicator.BlockArea = Infragistics.Web.UI.AjaxIndicatorBlockArea.Control;
