I have grid control

select <%--Select--%>

                </ItemTemplate>
            </asp:TemplateField>
        </columns>
            <pagersettings mode="NumericFirstLast" position="Top" pagebuttoncount="5" />
            <pagerstyle backcolor="Pink" />
        </cc:AppEngineGridView>

my code on row create

     protected override void OnRowCreated(GridViewRowEventArgs e)
            {
                try
                {
                    if (e.Row.RowType == DataControlRowType.DataRow)
                    {
                        e.Row.ID = this.ID + "_" + e.Row.RowIndex;
                        e.Row.Attributes.Add("onmouseover", "this.style.cursor='pointer';this.style.font.weight='bolder';");
                        e.Row.Attributes.Add("onclick", "DoNav('" + ((LinkButton)e.Row.FindControl("lbtn1")).ClientID + "');");
                    }

          }

    protected void grduser_RowUpdating(object sender, GridViewUpdateEventArgs e)
    {
        grdview_RowClickCommand(sender, e);
   }

Javascript :

    function DoNav(id)
  {
   $("#"+id).click();
}

Now my question is when i click on the row it do post back but it didnt call rowupdate event

How can do this i.e using javascript to call row update command of the grid.
