Following code is used in ASPX page:
<acw:GridWeb ID="grid1" runat="server" Width="70%" Height="645px"
Following code is used in code behind file:
protected void Page_Load(object sender, EventArgs e)
grid1.Visible = false;
protected void btnShow_Click(object sender, EventArgs e)
grid1.Visible = true;

In order to resolve this issue we need a sample application to view and analyze the issue. If issue persists, please forward us the sample application.
