Here is what I am looking for:

Not in Edit Mode:  The cell looks like a normal cell - with value 5

Edit Mode Started:  The cell changes to a button that shows the text Double and the cells original value - Double 5

The user clicks on the button

Edit mode ends, cell returns to normal cell - but now the value is 10.

It is actually how to create the button control, and make it have access to the cell value - to read and write.

Also, the editor and edit template needs to be assigned dynamically when the XamDataGrid raises the EditModeStarting, and be removed when the EditModeEnded is raised

Hello,

If you change the field to AllowEdit=true in the prior sample and set the template as the EditDataTemplate it will only show the button in edit mode.

You can also use the grid's DataPresenterCommands to exit edit mode when the button in clicked.

Please see modified sample.

Thanks, this almost exactly what I want...

Just one last question.  I will be building the field layout in code, and attaching the editor based on the data feed settings.  Each editor could have a different data template.

I have the following (from modifying your sample):

 Field editField = new Field("Amount");
                editField.Settings.AllowEdit = true;
                Style editorStyle = new Style(typeof(ControlHostEditor));
                editorStyle.Setters.Add(new Setter(ControlHostEditor.EditDataTemplateProperty, template));                
                editField.Settings.EditorStyle = editorStyle;

But whenever the grid appears, I don't see anything in the field.  How do I recreate this in code.  Also, is it possible just to change the FieldSettings after the field layout is initialized and have it work?

<igDP:Field Name="Amount" >
                            <igDP:Field.Settings>
                                <igDP:FieldSettings AllowEdit="True">
                                    <igDP:FieldSettings.EditorStyle>
                                        <Style TargetType="{x:Type igSamples:ControlHostEditor}">                                          
                                            
                                            <Setter Property="EditDataTemplate" Value="{StaticResource doubleRenderTemplate}" />
                                           
                                        </Style>
                                    </igDP:FieldSettings.EditorStyle>
                                </igDP:FieldSettings>
                            </igDP:Field.Settings>
                        </igDP:Field>

Hello,

You can let the grid generate the field layout automatically and then set the additional field settings in the FieldLayoutInitialized event:

private void XDG1_FieldLayoutInitialized(object sender, Infragistics.Windows.DataPresenter.Events.FieldLayoutInitializedEventArgs e)

{

   // check if it is the field layout to modify based on the underlying object name

   if (e.FieldLayout.Key.ToString() == "GridData")

     {

          // get the field to add the editor to

     Field field = e.FieldLayout.Fields["Amount"];

     if (field != null)

         {

       FieldSettings fs = new FieldSettings(); 

       fs.AllowEdit = true;

       // Get DataTemplate from Grid's resources

       DataTemplate dt = XDG1.Resources["doubleRenderTemplate"] as DataTemplate;

       Style style = new Style(typeof(ControlHostEditor));

       style.Setters.Add(new Setter(ControlHostEditor.EditDataTemplateProperty, dt));

       fs.EditorStyle = style;

       field.Settings = fs;

            }

      }

}

I have attached the modified sample demonstrating this.

Please let me know if you have any questions.
