Ok. I have attached a project that replicates both issues I am seeing. So basically I'm not doing any of the binding myself; I let the grid do it for me. In my actual xaml, I define my own field, editor types and edit as, but the behavior is exactly the same as allowing the grid to create the fields on its own. 

Thanks,

I see the issue you are talking about. The internal binding UpdateSourceTrigger needs to be changed from the default "LostFocus" to "PropertyChanged". I will look into how to do this and post the solution.

For now, I'm using the following workaround:

1.  Add the following Field settings to my boolean fields:

                <igDP:Field.Settings>
                  <igDP:FieldSettings AllowEdit="True" EditAsType="{x:Type sys:Boolean}" EditorType="{x:Type igEditors:XamCheckEditor}" LabelWidth="60" CellWidth="60">
                    <igDP:FieldSettings.EditorStyle>
                      <Style TargetType="{x:Type igEditors:XamCheckEditor}">
                        <EventSetter Event="ValueChanged" Handler="HandleValueChangedAccept" />
                      </Style>
                    </igDP:FieldSettings.EditorStyle>

                  </igDP:FieldSettings>
                </igDP:Field.Settings>

and:

                <igDP:Field.Settings>
                  <igDP:FieldSettings AllowEdit="True" EditAsType="{x:Type sys:Boolean}" EditorType="{x:Type igEditors:XamCheckEditor}" LabelWidth="60" CellWidth="60" >
                    <igDP:FieldSettings.EditorStyle>
                      <Style TargetType="{x:Type igEditors:XamCheckEditor}">
                        <EventSetter Event="ValueChanged" Handler="HandleValueChangedRollback" />
                      </Style>
                    </igDP:FieldSettings.EditorStyle>
                  </igDP:FieldSettings>
                </igDP:Field.Settings>

I am hooking a handler to the ValueChanged event on the XamCheckEditor.

2.  Implement the handling methods:

       void HandleValueChangedAccept(object sender, RoutedPropertyChangedEventArgs<object> e)
        {
            bool newValue = (bool)e.NewValue;
            if (!newValue) return;

            DependencyObject o = Infragistics.Windows.Utilities.GetAncestorFromType(e.OriginalSource as DependencyObject, typeof(DataRecordCellArea), true);
            DataRecordCellArea dataRecord = o as DataRecordCellArea;
            if (dataRecord == null) return;
           
            DAO dao = dataRecord.Record.DataItem as DAO ;
            dao.Accept = (bool)e.NewValue;
        }

        void HandleValueChangedRollback(object sender, RoutedPropertyChangedEventArgs<object> e)
        {
            bool newValue = (bool)e.NewValue;
            if (!newValue) return;

            DependencyObject o = Infragistics.Windows.Utilities.GetAncestorFromType(e.OriginalSource as DependencyObject, typeof(DataRecordCellArea), true);
            DataRecordCellArea dataRecord = o as DataRecordCellArea;
            if (dataRecord == null) return;

            DAO dao = dataRecord.Record.DataItem as DAO ;
            dao .Rollback = (bool)e.NewValue;
        }

Notice that my logic dictates that two values cannot be set to true. My DAO setters handle this logic. But this creates an opportunity for an infinite loop. Since dao.Rollback may change the value of dao.Accept, the ValueChanged handlers for the checkboxes may keep on calling each other infinitely. For this purpose, I make sure that the handler doesn't do anything if the new value is false.

So this is a bit of a hackish way to do this, but it works. Chris, let me know if there's a more elegant way to do this using the UpdateSourceTrigger property of the internal binding.

I'm having same issues with bool type values I add to XamDataGrid. Here's the simple project I made with same thing.

 Any updates on this topic ?

Glad to know this works!

I implemented the xamdatagrid with checkboxes (placed in Cellvalue presenter) I added checked unchecked events for the check box. But i am facing one problem . On scroll of the xamdatagrid scroll bar level. I am seeing some of the check boxes are checked and unchecked. My application is behaving differntly. Can you please give some inputs on this.

I implemented the  sample like this

<Window x:Class="Scrollbarissue_OnlyCheckBox.Window2"

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

Title="Window2" Height="300" Width="300">

<Grid>

<igDP:XamDataGrid Name="myGrid" Height="250">

<igDP:XamDataGrid.Resources>

<Style TargetType="{x:Type igDP:CellValuePresenter}" x:Key="BoolFieldOverride">

<Setter Property="Template">

<Setter.Value>

<ControlTemplate TargetType="{x:Type igDP:CellValuePresenter}">

<CheckBox HorizontalAlignment="Center" VerticalAlignment="Center"

IsChecked="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Content}"/>

</ControlTemplate>

</Setter.Value>

</Setter>

</Style>

</igDP:XamDataGrid.Resources>

<igDP:XamDataGrid.FieldLayoutSettings>

<igDP:FieldLayoutSettings AutoGenerateFields="False" />

</igDP:XamDataGrid.FieldLayoutSettings>

</igDP:Field.Settings>

</igDP:Field>

<igDP:Field Name="Rollback" Label="Option Rollback" >

<igDP:Field.Settings>

CellValuePresenterStyle="{StaticResource BoolFieldOverride}"/>

</igDP:Field.Settings>

</igDP:Field>

<igDP:Field Name="Accept" Label="Option Accept" >

<igDP:Field.Settings>

</igDP:Field.Settings>

</igDP:Field>

</igDP:FieldLayout.Fields>

</igDP:FieldLayout>

</igDP:XamDataGrid.FieldLayouts>

</igDP:XamDataGrid>

</Window>

/// <summary>

public partial class Window2 : Window

DataObject dataObj;

dataObj.Id = Guid.NewGuid().ToString();

dataObj = new DataObject();

dataObj.Rollback = false;
