I have one last problem
the grid is inside a viewport.
The height dela grid and its layout are calculated dynamically so as to avoid the scrollbar.
When I insert a new record I must draw this script that changes dynamically paging.
The record before was in first position after it last position.
How can I do to remain in first place?
Here's the code:
<%@ Page Language="C#" %>
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
<script runat="server">
protected void Page_Load(object sender, EventArgs e)
{
if (!X.IsAjaxRequest)
{
this.BindData();
}
}
protected void MyData_Refresh(object sender, StoreRefreshDataEventArgs e)
{
this.BindData();
}
private void BindData()
{
Store1.DataSource = this.Data;
Store1.DataBind();
}
private object[] Data
{
get
{
DateTime now = DateTime.Now;
return new object[]
{
new object[] { "3m Co", 71.72, 0.02, 0.03, now },
