That is to say they are each in their OWN unbound column, but in their own CellValuePresenter.

These are my two columns:

                                                        <igDataGrid:UnboundField Name="CustomItem" Label="EMO">
                                                            <igDataGrid:UnboundField.Settings>
                                                                <igDataGrid:FieldSettings LabelWidth="40" CellWidth="40" AllowEdit="True">
                                                                    <igDataGrid:FieldSettings.CellValuePresenterStyle>
                                                                        <Style TargetType="{x:Type igDataGrid:CellValuePresenter}">
                                                                            <Setter Property="Template">
                                                                                <Setter.Value>
                                                                                    <ControlTemplate TargetType="{x:Type igDataGrid:CellValuePresenter}">
                                                                                        <igEditors:XamCheckEditor Name="chkCustomItem" ValueChanged="chkCustomItem_ValueChanged" HorizontalAlignment="Center"></igEditors:XamCheckEditor>                                                                                      
                                                                                    </ControlTemplate>
                                                                                </Setter.Value>
                                                                            </Setter>
                                                                        </Style>
                                                                    </igDataGrid:FieldSettings.CellValuePresenterStyle>
                                                                </igDataGrid:FieldSettings>
                                                            </igDataGrid:UnboundField.Settings>
                                                           
                                                        </igDataGrid:UnboundField>
                                                        <igDataGrid:UnboundField Name="BuyOutEditButton" Label="B/O">
                                                            <igDataGrid:UnboundField.Settings>
                                                                <igDataGrid:FieldSettings LabelWidth="40" CellWidth="40" AllowEdit="True">
                                                                    <igDataGrid:FieldSettings.CellValuePresenterStyle>
                                                                        <Style TargetType="{x:Type igDataGrid:CellValuePresenter}">
                                                                            <Setter Property="Template">
                                                                                <Setter.Value>
                                                                                    <ControlTemplate TargetType="{x:Type igDataGrid:CellValuePresenter}">
                                                                                        <Button Name="cmdEditBuyout" MinWidth="20" Click="cmdEditBuyout_Click"  >Edit</Button>
                                                                                    </ControlTemplate>
                                                                                </Setter.Value>
                                                                            </Setter>
                                                                        </Style>
                                                                    </igDataGrid:FieldSettings.CellValuePresenterStyle>
                                                                </igDataGrid:FieldSettings>
                                                            </igDataGrid:UnboundField.Settings>
                                                        </igDataGrid:UnboundField>

Bump

This also works for me -- I actually capture the button event -- I did not tell you but I have a xamchk button in the grid so here's how I ended up doing it.

            DataRecord dr = ((XamCheckEditor)sender).DataContext as DataRecord;
            DataRecordPresenter drp = DataRecordPresenter.FromRecord(dr.Cells["BuyOutEditButton"].Record) as DataRecordPresenter;
            Button b = Infragistics.Windows.Utilities.GetDescendantFromName(drp, "cmdEditBuyout") as Button;
            b.IsEnabled = (bool)((XamCheckEditor)sender).Value;

THANK YOU!!!!

The procedural code for this should look something like:

On Cell Updated Event

check if the cell is the the one with the checkbox,

then:

            DataRecordPresenter drp = DataRecordPresenter.FromRecord(e.Cell.Record) as DataRecordPresenter;

            if ((bool)e.Cell.Value == false)

            {

                Button b = Utilities.GetDescendantFromName(drp, "cmdEditBuyout") as Button;

                b.IsEnabled = false;

            }

Well,

I read again the initial post, and I see that you want to change the IsEnabled property of the Button according to a checkbox from another field. This can be done in the xaml, without any procedural code. You can try this:

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

            <Setter Property="Template">

                <Setter.Value>

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

                            <Button Name="cmdEditBuyout" 

                                    Background="{TemplateBinding Background}"

                                    MaxWidth="20" Content="ED"/>

                        </ControlTemplate>

                </Setter.Value>

            </Setter>

                <Style.Triggers>

                    <DataTrigger Binding="{Binding Path=Cells[0].Value}" Value="False">

                        <Setter Property="IsEnabled" Value="False"/>

                    </DataTrigger>

                </Style.Triggers>

            </Style>

I am also attaching the sample project for this.

Hope this helps.

I tried to get the parent of the checkbox so I could look for the child button, but this did not work.  Any ideas?

            DependencyObject parent = Infragistics.Windows.Utilities.GetAncestorFromType(((XamCheckEditor)sender), ((XamCheckEditor)sender).Parent.GetType(), false);

Thanks -- I would have never figured this out.  I don't suppose you ahve any exampels of how to call this...
