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();
}
