EditorWidget - can't to save data to the geodatabase

[AnatoliiTerentiev]

I try to use EditorWidget control to edit layers with feature access. I can delete items from geodatabase (sql server express), but can't to save result of feature editing. If I try to edit existing feature after click "OK" button - this button becomes not active and data not saved even on the Map. If I try to edit new added feature - it normally saved on the map, but not saved in geodatabase.
    If I try use this layer in arcgis.com map , then all operation are performed normally and data properly saved in geodatabase.
XAML:

       <esri:Map x:Name="MyMap" Background="White" WrapAround="true" Extent="6095000,6810000,6900000,7258000">
            <i:Interaction.Triggers>
                <i:EventTrigger EventName="MouseEnter">
                    <ei:ChangePropertyAction TargetName="myMenuItems" PropertyName="Visibility">
                        <ei:ChangePropertyAction.Value>
                            <Visibility>Collapsed</Visibility>
                        </ei:ChangePropertyAction.Value>
                    </ei:ChangePropertyAction>
                </i:EventTrigger>
            </i:Interaction.Triggers>
            <esri:ArcGISDynamicMapServiceLayer ID="BaseLayer"

                               OutFields="*"
                               Mode="OnDemand" />
        </esri:Map>
        <StackPanel Orientation="Vertical" HorizontalAlignment="Right" Margin="0,80,224,0"   VerticalAlignment="Top" >

                                      ShowAttributesOnAdd="True"  
                                      Loaded="EditorWidget_Loaded"/>
        </StackPanel>

and code behind:

namespace Module2
{
    public partial class MapControl : UserControl
    {
        public MapControl()
        {
            InitializeComponent();
        }

        private void ArcGISDynamicMapServiceLayer_Initialized(object sender, EventArgs e)
        {
            ESRI.ArcGIS.Client.ArcGISDynamicMapServiceLayer myArcGISDynamicMapServiceLayer =
                  MyMap.Layers["chsLayer"] as ESRI.ArcGIS.Client.ArcGISDynamicMapServiceLayer;
            int[] myVisibleLayers = {0};
            myArcGISDynamicMapServiceLayer.VisibleLayers = myVisibleLayers;
        }

        private void EditorWidget_Loaded(object sender, System.Windows.RoutedEventArgs e)
        {
            string[] myLayerIDs = { "myEvents" };
            MyEditorWidget.LayerIDs = myLayerIDs;
        }
    }
}

What could be wrong?

[AnatoliiTerentiev]

I try to test EditorWidget example , added  my layer with feature access "myEvents"
XAML:

<UserControl x:Class="Module2.MapControl"

        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

        <esri:Map x:Name="MyMap" Background="White" WrapAround="true" Extent="6095000,6810000,6900000,7258000">
            <esri:ArcGISDynamicMapServiceLayer ID="BaseLayer" 
          Url="http://terentievai:6080/ArcGIS/rest/services/rk/MapServer" />

            <esri:FeatureLayer ID="Points of Interest" DisableClientCaching="True" 
                               AutoSave="False"
                               Url="http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Fire/Sheep/FeatureServer/0"

            <esri:FeatureLayer ID="myEvents" DisableClientCaching="True" 
                               AutoSave="False"
                               Url="http://terentievai:6080/ArcGIS/rest/services/chs/FeatureServer/0" 
                               OutFields="*"
                               Mode="OnDemand" />
        </esri:Map>

        <StackPanel  x:Name="EditorToolStrip" Margin="0,5,5,0" >
            <Border Background="#00919191" CornerRadius="5"
               HorizontalAlignment="Right"  VerticalAlignment="Top"
               Padding="5" BorderBrush="Transparent">
                <Border.Effect>
                    <DropShadowEffect Color="Black" Direction="-45" BlurRadius="20" Opacity=".75" />
                </Border.Effect>
                <StackPanel Orientation="Vertical" HorizontalAlignment="Right" Margin="0,5,5,0" VerticalAlignment="Top" >
                    <esri:EditorWidget x:Name="MyEditorWidget"
                             Map="{Binding ElementName=MyMap}" 
                                      Width="300" 
                                      AutoSelect="False"
                                      AlwaysDisplayDefaultTemplates="True" 
                                      GeometryServiceUrl="http://tasks.arcgisonline.com/ArcGIS/rest/services/Geometry/GeometryServer"
                                      ShowAttributesOnAdd="True"  
                                      Loaded="EditorWidget_Loaded"/>
                </StackPanel>
            </Border>
        </StackPanel>

    </Grid>
</UserControl>

and code behind:

namespace Module2
{
    public partial class MapControl : UserControl
    {
        public MapControl()
        {
            InitializeComponent();
        }
        private void EditorWidget_Loaded(object sender, System.Windows.RoutedEventArgs e)
        {
            string[] myLayerIDs = { "Points of Interest", "Evacuation Perimeter", "myEvents" };
            MyEditorWidget.LayerIDs = myLayerIDs;
        }
    }
}

The result of testing:
1. Layer "Points of interest" works normally. Result of editing saves normally.
2. Layer "myEvents" works as described in previous message.
Thus it can be assumed that the problem  is in the layer or  in  geodatabase. However, confuses that if test service in arcgis.com  MAP, the changes are saved for layer myEvents too.

[AnatoliiTerentiev]

Any ideas how to fix?
1. Can't anybody say what steps can I take to solve the problem?
2. Now I made connection to geodatabase from "sa" , temporarily. This connection I use in the service. Is it correct?
3. May be some checklist - did I all necessary?
