Hi,
I am working on a application where i am using rowupdating event of the gridview. I am using templatefield in my columns so i am not able to get the new values from the textboxws that i am having in the gridview. How can i get the new values from the textboxes. Following is my code in rowupdating:

protected void gviewTemplate_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
    gviewTemplate.EditIndex = -1;
    string rowNum = ViewState["ID"].ToString();
    Label lbl2 = (Label)gviewTemplate.Rows[e.RowIndex].FindControl("lblTemplateName");
    Label lbl1 = (Label)gviewTemplate.Rows[e.RowIndex].FindControl("lblUploaded");

    TextBox txtTempName = (TextBox)gviewTemplate.Rows[e.RowIndex].FindControl("txtTemplateName");
    TextBox txtHeading = (TextBox)gviewTemplate.Rows[e.RowIndex].FindControl("txtHeading");
    TextBox txtCoupon = (TextBox)gviewTemplate.Rows[e.RowIndex].FindControl("txtCouponText");
    TextBox txtBrand = (TextBox)gviewTemplate.Rows[e.RowIndex].FindControl("txtBrandName");
    TextBox txtSearchText = (TextBox)gviewTemplate.Rows[e.RowIndex].FindControl("txtSearch");
    TextBox txtDiscount = (TextBox)gviewTemplate.Rows[e.RowIndex].FindControl("txtDiscount");
    TextBox txtStartDt = (TextBox)gviewTemplate.Rows[e.RowIndex].FindControl("txtStartDt");
} 

i want to get the new values form these textboxes but it is always giving me old values. and yes, e.Newvalues is not giving me anything. It is always empty. This is small extract from my gridview design:

<asp:GridView runat="server" AutoGenerateColumns="False"  
                        ID="gviewTemplate" onrowdatabound="gviewTemplate_RowDataBound" DataKeyNames="F1"

                        onrowdeleting="gviewTemplate_RowDeleting" 
                        onrowupdated="gviewTemplate_RowUpdated">
