I am trying to force a CMSRepeater control to update its content after I programatically change its Path in the code behind of my WebPart. A LinkButton is wired to the btn_Click handler in the code below. I can see that the Path value gets changed but the Repeater doesn't update when I call DataBind(). Is there something wrong with this methodology?

protected void btn_Click(object sender, CommandEventArgs e)
{
string path = "";
string output = "";
CommandEventArgs args = e;
if(args.CommandName == "state")
{
switch(args.CommandArgument.ToString())
{
case "or":
path += "Path1/%";
break;
case "wa":
path += "Path2/%";
break;
}

foreach (Control c in this.Controls)
{

if (c.GetType().ToString() == "CMS.Controls.CMSRepeater")
{
CMSRepeater list = (CMSRepeater)c;
list.Path = path;
list.DataBind();

}
}

// DataBind(false);
}

}
