Hi ,

I Created one multicolumn comboeditor using following code. The problem with this code is that

it does not allow me to change the column width of xamdatagrid at run time manually.

    <igEditors:XamComboEditor Margin="12,155,12,144" Name="xamComboEditor1">
            <igEditors:XamComboEditor.Resources>
                <local:RecordToDisplayTextConverter x:Key="conv"/>
                <Style TargetType="{x:Type igEditors:XamComboEditor}">
                    <Setter Property="ValueToDisplayTextConverter" Value="{StaticResource conv}"/>
                    <Setter Property="ValueToTextConverter" Value="{StaticResource conv}"/>
                    <Setter Property="Background" Value="{DynamicResource {x:Static SystemColors.WindowBrushKey}}" />
                    <Setter Property="BorderBrush" Value="{DynamicResource {x:Static igEditors:EditorsBrushKeys.EditorsNormalBorderFillKey}}" />
                    <Setter Property="BorderThickness" Value="1" />
                    <Setter Property="Padding" Value="1,2,1,2"/>
                    <Setter Property="Margin" Value="{DynamicResource {x:Static igEditors:EditorsBrushKeys.TextEditorMarginKey}}" />
                    <Setter Property="SnapsToDevicePixels" Value="True" />
                    <Setter Property="Template">
                        <Setter.Value>
                            <ControlTemplate TargetType="{x:Type igEditors:XamComboEditor}">
                                <Border x:Name="MainBorder"
         Background="{TemplateBinding Background}"
         BorderBrush="{TemplateBinding BorderBrush}"
         BorderThickness="{TemplateBinding BorderThickness}"
       SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}">
                                    <Grid>
                                        <Grid.RowDefinitions>
                                            <RowDefinition/>
                                        </Grid.RowDefinitions>
                                        <Grid.ColumnDefinitions>
                                            <ColumnDefinition Width="*" />
                                            <ColumnDefinition Width="Auto" />
                                        </Grid.ColumnDefinitions>
                                        <TextBlock x:Name="PART_TextBlock"
        Grid.Column="0"
        Padding="{TemplateBinding Padding}"
        Margin="1,0,0,0"
        Text="{TemplateBinding DisplayText}"
        HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
        VerticalAlignment="{TemplateBinding VerticalContentAlignment}"
        Foreground="{TemplateBinding Foreground}"
        />
                                        <ToggleButton x:Name="PART_DropDownButton"
        Grid.Column="1"
        Width="{DynamicResource {x:Static SystemParameters.VerticalScrollBarWidthKey}}"
        IsChecked="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=IsDropDownOpen, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
        ClickMode="Press"
        Style="{TemplateBinding DropDownButtonStyle}"
        Visibility="{TemplateBinding DropDownButtonVisibility}"
        />
                                    </Grid>
                                </Border>
                                <ControlTemplate.Triggers>
                                    <Trigger Property="IsEmbedded" Value="False">
                                        <Setter Property="DropDownButtonDisplayMode" Value="Always"/>
                                        <Setter Property="Padding" Value="2,2,2,2" />
                                    </Trigger>
                                    <Trigger Property="IsMouseOver" Value="True">
                                        <Setter TargetName="PART_DropDownButton" Property="Tag" Value="MouseOverControlTrue" />
                                    </Trigger>
                                </ControlTemplate.Triggers>
                            </ControlTemplate>
                        </Setter.Value>
                    </Setter>
                </Style>
                <DataTemplate DataType="{x:Type igEditors:ComboBoxDataItem}" >
                    <Grid>
                        <igDP:XamDataGrid x:Name="TextBlock" SelectedItemsChanging="PART_FocusSite_SelectedItemsChanging"
                                                  HorizontalAlignment="Stretch" DataSource="{Binding Path=Value}"
                                                  HorizontalContentAlignment="Stretch"
                                                   >
                            <igDP:XamDataGrid.FieldSettings>
                                <igDP:FieldSettings CellClickAction="SelectRecord"/>
                            </igDP:XamDataGrid.FieldSettings>
                        </igDP:XamDataGrid>
                    </Grid>
                </DataTemplate>
            </igEditors:XamComboEditor.Resources>
        </igEditors:XamComboEditor>.

Any suggestion on this
