But the problem is that the text goes out of the "blue rectangle".
I was unable to reproduce. Here is my test case. Tested under IE9.
Example
<%@ 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.Store1.DataSource = new object[]
{
new object[] { "testtesttesttesttesttesttesttesttesttesttesttesttest" },
};
this.Store1.DataBind();
}
}
</script>

Well, you can achieve it.
Example
<%@ Page Language="C#" %>
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
