I am having an issue with opening a modalextender which contains a window from clicking on an ASP LinkButton on a gridview. I need to pass a value from the row to the modal page I am showing.
Here is my code for the link button in my gridview.

<asp:TemplateField ShowHeader="False">
  <asp:LinkButton ID="linkNew" CausesValidation="false" CommandName=""runat="server" Text="New Tx">
I have 
protected void GridView_RowDataBound(object sender, GridViewRowEventArgs e)
        if (e.Row.RowType == DataControlRowType.DataRow)
        (e.Row.FindControl("linkNew") as LinkButton).Attributes.Add("onclick", "ShowEditModal('" + (e.Row.FindControl("lbLocator") as Label).Text + "');");

The Javascript is:

function ShowEditModal(LocatorID) {
                 var frame = $get('IframeEdit');
                 frame.src = "Receive.aspx?UIMODE=NEW&EID=" + LocatorID;

Finally the IframeEdit
<div id="DivEditWindow" style="display: none;" class="popupConfirmation">
                <iframe id="IframeEdit" frameborder="0" scrolling="no" height="400" width ="600">

The code in Receive.aspx page is this
public enum UIMODE
    public partial class Receive : System.Web.UI.Page
        public UIMODE UIMode
                if (ViewState["UIMODE"] == null)
                    ViewState["UIMODE"] = new UIMODE();
                return (UIMODE) ViewState["UIMODE"] ;
                ViewState["UIMODE"] = value;
        private string EID
                string text = (string)ViewState["EID"];
                if (text != null)
                    return text;
                    return string.Empty;
                ViewState["EID"] = value;
 protected void Page_Load(object sender, EventArgs e)
            if (!IsPostBack)
                string qsUIMODE = Request.QueryString["UIMODE"];
                if (string.IsNullOrEmpty(qsUIMODE) == false)
                    UIMode = (UIMODE)Enum.Parse(typeof(UIMODE), qsUIMODE);
                    EID = Request.QueryString["EID"];
                    hdnWindowUIMODE.Value = UIMode.ToString();
                MultiViewReceive.ActiveViewIndex = 1;

I can see the window popup correctly when the linkbutton is clicked, but it then dissapears right away and I need it to stay on the page.

Any help would be great. Please let me know if anything else is needed from my code as well.

This seems to run the page_load event twice and on the second one qsUIMODE is NULL. The modal window then closes, but I need it to be open
