在NetAdvantage for .NET中我们可以用Text和ImageUrl属性来分别将指标的等待消息配置为显示文本或图像。如果两个属性都设置了，那么Text属性优先于ImageUrl属性。在设计和运行时，我们都可以在控制层配置AJAX指示灯。

代码如下：

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;
