I have a button outside of a warp, and webgrid inside the warp. Clicking the button trigger reloading data into the webgrid, and I expect this process is AJAX. But the grid did not refreshed.

The sample works for WebChart. 

Any idea?

protected void Button1_OnClick(object sender,

System.EventArgs e)

{

//this.UltraChart1.DataSource = this.GetColumnData();

//this.UltraChart1.DataBind();

//this.UpdateTitle();

AlertDataAdapter ada = new AlertDataAdapter();

UltraWebGrid g = (UltraWebGrid)this.FindControl("grid");

g.DataSource = null;

g.DataSource = ada.GetAlerts("Severity", 3, 2); // new data

g.DataBind();

}

<div> <asp:Button ID="Button1" OnClick="Button1_OnClick" runat="server" Text="Button1" /> </div>

<div> <asp:Button ID="Button2" OnClick="Button2_OnClick" runat="server" Text="Button2" /> </div>

<div style="height: 360px; padding-left:40px; padding-top:40px;">

<igmisc:WebAsyncRefreshPanel ID="WebAsyncRefreshPanel1" runat="server"

Height="219px" Width="439px" TriggerControlIDs="Button1,Button2">
