In order to be able to sort in list form, raised lookup web, you must do the following:

1.You need to make sure that the LookUp form is correct. For example, to use the standard user form located on the test stand, then the settings in web.config shall be as follows:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
	...
  <httpHandlers>
	...
      <add verb="*" path="LookUpForm.aspx" type="ICSSoft.STORMNET.Web.AjaxControls.HandlerFactories.PageHandlersFactory`1[[ICSSoft.STORMNET.Web.Controls.LookUpForm, TestStand(ASP.NET Application)]], ICSSoft.STORMNET.Web.AjaxControls" validate="false" />
  </system.web>
  <system.webServer>
    <handlers>
		...
      <add name="LookUpForm" path="LookUpForm.aspx" verb="*" type="ICSSoft.STORMNET.Web.AjaxControls.HandlerFactories.PageHandlersFactory`1[[ICSSoft.STORMNET.Web.Controls.LookUpForm, TestStand(ASP.NET Application)]], ICSSoft.STORMNET.Web.AjaxControls" resourceType="Unspecified" preCondition="integratedMode" />
    </handlers>
  </system.webServer>
</configuration>

2.To check that the form method is used ApplyWolvSettings WOLVSettApplyer application availability (not located in the Assembly AjaxControls) and that no calls to the base method ApplyWolvSettings (this call can grind settings).

namespace ICSSoft.STORMNET.Web.Controls
{
    /// <summary> 
    /// Class applied forms of lyapov. 
    /// </summary> 
    public class LookUpForm : AjaxControls.Forms.LookUpForm
    {
        /// <summary> 
        /// Apply the settings to wolv lying on the form lookup. 
        /// Overridden method implements the application logic of the adjustments WOLV on the form. 
        /// </summary> 
        protected override void ApplyWolvSettings()
        {
            new WOLVSettApplyer().SettingsApply(LookUpFormWOLV);
        }
    }
}

3.In WOLVSettApplyer override method ApplyLookUpSettings. And assign the necessary operation.

namespace ICSSoft.STORMNET.Web
{
    /// <summary> 
    /// The tuner for WOLV'and available for application programmers. 
    /// </summary> 
    public class WOLVSettApplyer : AjaxControls.WolvSettApplyer
    {
        /// <summary> 
        /// Apply settings for WOLV in the form of lookup. Called if the HTTP request 
        /// there is a parameter <see cref="P:ICSSoft.STORMNET.Web.Tools.WebParamController.OpenedFromLookupParamName"/>. 
        /// </summary> 
        /// <param name="wolv">WOLV to which you want the settings to apply.</param> 
        public override void ApplyLookUpSettings(WebObjectListView wolv)
        {
            base.ApplyLookUpSettings(wolv);
            Type[] dataObjectTypes = wolv.DataObjectTypes;
            if (wolv.ID.Equals(LookUpForm.WebObjectListViewID)) // Impose the desired condition. 
            {
                wolv.Operations.UserColumnsSort = true;
            }
        }
    }
}
