Can you set a webpart where condition from the page template?

I want to put some code at the top of my page template that looks like this:

    string curNode = CMS.CMSHelper.CMSContext.CurrentPageInfo.NodeID;
    string where = "";

    switch (curNode){
    case "[NodeID1]":
        where = "Region = 1";
        break;
    case "[NodeID2]":
        where = "Region = 2";
        break;
    case "[NodeID3]":
        where = "Region = 3";
        break;
    case "[NodeID4]":
        where = "Region = 4";
        break;
    }

    this.QueryDataSource.WhereCondition = where;
    this.QueryDataSource.ReloadData(true);

I have 4 pages that use the same template which populates a uniview based on a custom query. Since they share the template I need to dynamically set the where condition as shown above. When I put that at the top of my template I get the following error.

does not contain a definition for 'QueryDataSource' and no extension method 'QueryDataSource'

Seems like I am missing a reference, can someone help with he syntax?

Thanks

RE:Can you set a webpart where condition from the page template?

Solved. This code can be added to a custom layout of a webpart:

 <script runat="server">
   protected override void OnLoad(EventArgs e) 
{ 
base.OnLoad(e); 
 string curNode = CMS.CMSHelper.CMSContext.CurrentPageInfo.NodeID;
    string where = "";

    switch (curNode){
    case "[NodeID1]":
        where = "Region = 1";
        break;
    case "[NodeID2]":
        where = "Region = 2";
        break;
    case "[NodeID3]":
        where = "Region = 3";
        break;
    case "[NodeID4]":
        where = "Region = 4";
        break;
    }
    
    this.srcElem.WhereCondition = where;    
    }
  </script>

This dynamically sets the where condition for my QueryDataSource control.

Member	vcarter - 8/21/2013 8:48:54 AM RE:Can you set a webpart where condition from the page template? Use the layout attribute of the query webpart, create a custom layout and add your desired code. In my case I am checking the node ID of the page and selecting a regionID based on the page filtering my content.
