ASP.NET: Disabling ViewState from a DataGrid

For performance reasons, I prefer to disable ViewState in all ASP.NET controls unless I explicitly need to. This arises from my desire to keep web page HTML payload to 15KB for sub-second response times (a personal UI design goal).

/// <summary> /// Class member used to disable ViewState at the DataGridItem level. This method must be /// called after every databinding event /// </summary> /// <param name=”dg”></param> public void DisableViewState(System.Web.UI.WebControls.DataGrid dg) {     foreach (System.Web.UI.WebControls.DataGridItem dgi in dg.Items)     {         dgi.EnableViewState = false;     } } /// <summary> /// Sets the selected item for a control. Use this to reset listboxes or dropdown /// boxes and minimise the use of ViewState between PostBacks /// </summary> /// <param name=”lc”>The instance of the Control that we wish to databind</param> public void SetSelectedItem(System.Web.UI.WebControls.ListControl lc) {     String val = Request.Form[lc.ID];     if (val != null)         for (int i = 0; i < lc.Items.Count; i++)             if (lc.Items[i].Value == val)             {                 lc.Items[i].Selected = true;                 return;             } }
