Subject: [mapserver-users] polygon fill

hi all

iam trying to highlight the villages based on query

but only one polygon is highlighting
the query is based on the area of the villages, when user enters area 
<=********** ,it is displaying 13 villages in the grid and also same time it 
has to highlight the villages on the map
my code is

aspx page

 protected void btnselect_Click(object sender, EventArgs e)
    {

        string query = "";

        query = String.Format(" select gid,box(geom),villname,geom,area(geom) 
from villages where area(geom) " + ddlsymb.SelectedValue + "  " + txtarea.Text 
+ " ");

        dt = MyClass.getData(query);

        if (dt == null || dt.Rows.Count == 0)
        {
            Response.Write("No record found, Try Zoom in and click close to 
feature.");
        }
        else
        {
            dr = dt.Rows[0];
            //String selectedGID = dr["gid"].ToString();

            //gid = selectedGID;
            var layername = "villages";

            for(int i=0;i<dt.Rows.Count;i++)
{
 dr = dt.Rows[i];
 String selectedGID = dr["gid"].ToString();

 gid = selectedGID;
            
Response.Write(String.Format(@"<script>window.parent.highlightnav('{0}','{1}');</script>",
 gid, layername));
            //Locate(query);
    }

            if (dt.Columns.Contains("gid"))
            {
                dt.Columns.Remove("gid");
            }
            if (dt.Columns.Contains("geom"))
            {
                dt.Columns.Remove("geom");
            }
            GridView1.DataSource = dt;
            GridView1.DataBind();
        }
    }


js page

function highlightnav(gid,layername)
{

    bPoint.params.gid = gid;
    bPoint.params.tbl = layername;
    //bPoint.params.getElementById = geom;
    bPoint.redraw();
}
