The following code will launch the RowEditingTemplate but i have not found a way to push the added row into the main part of the grid without tabing to the end of the new row. In order words, call the RowAdding event on the server.  Have any ideas?

function GetEditingCore() {
    var wdgConferenceRooms = $find('wdgConferenceRooms');
    var behaviors;
    var editCore;

    behaviors = wdgConferenceRooms.get_behaviors();
    editCore = behaviors.get_editingCore();

    return editCore;
}
function GetRowEditingTemplate() {
    var rowTemplate;
    var editCore;

    editCore = GetEditingCore();
    rowTemplate = editCore.get_behaviors().get_rowEditingTemplate();

    return rowTemplate;
}

function wdgConferenceRooms_RowAdding_EnteringEditMode(sender, eventArgs)
{
 ///<summary>
 ///
 ///</summary>
 ///<param name="sender" type="Infragistics.Web.UI.WebDataGrid"></param>
 ///<param name="eventArgs" type="Infragistics.Web.UI.CancelEditModeEventArgs"></param>

    //Add code to handle your event here.

    var rowTemplate = GetRowEditingTemplate();
    var row = eventArgs.getCell().get_row();

    rowTemplate.enterEditMode( row );
}
