Hi

I am creating the fields of my xam datagrid dynamically. I want to set the visibility of the unbound field using multibinding. Can you please point me in the right direction?

I am pasting my current working xaml with the relevant xaml in bold as well as the partial code that i did to implement the same using code behind.

 <igDP:XamDataGrid
            Name="HotBucketsGrid"
            Theme="Office2k7Black"
            Background="Transparent"
                AutoFit="true"
            Style="{DynamicResource PerformantGrid}"           
            GroupByAreaLocation="None"
            DataSource="{Binding HotBuckets}">
                <igDP:XamDataGrid.FieldLayouts>
                    <igDP:FieldLayout IsDefault="True">

 <igDP:FieldLayout.Fields>
 <igDP:UnboundField  Row="0" Column="4"  Name="OrderCount" BindingPath="OrderCountUtilization"  Label="OrderCount[%]" Converter="{StaticResource LimitConverter}">
                                <igDP:Field.Settings>
                                    <igDP:FieldSettings AllowSummaries="False" CellValuePresenterStyle="{StaticResource DynamicPercentageFieldCell}" >
                                    </igDP:FieldSettings>
                                </igDP:Field.Settings>
                                <igDP:Field.Visibility>
                                    <MultiBinding Converter="{StaticResource LimitFieldVisibilityConverter}" ConverterParameter="OrderCountcurrValue">
                                        <Binding Source="{StaticResource DATA_HotBucketsViewModel}" Path="." />
                                        <Binding Source="{StaticResource DATA_HotBucketsViewModel}" Path="FieldVisibilityChanged" />
                                    </MultiBinding>
                                </igDP:Field.Visibility>
                            </igDP:UnboundField>

 <igDP:UnboundField Row="1" Column="2"  Name="BucketId" BindingPath="ForEachDetails" Label="{x:Null}">
                                <igDP:Field.Settings>
                                    <igDP:FieldSettings CellContentAlignment="ValueOnly"  AllowRecordFiltering ="False"  AllowSummaries="False" CellValuePresenterStyle="{StaticResource ForEachDetailsFieldCellStyle}" />
                                </igDP:Field.Settings>
                            </igDP:UnboundField>

</igDP:FieldLayout.Fields>
</igDP:FieldLayout>
</igDP:XamDataGrid.FieldLayouts>
</igDP:XamDataGrid>

Snippet of Codebehind where i create my fields dynamically and attempt to set the visibility.

 
 IValueConverter limitConverter = new LimitValueConverter();
IMultiValueConverter limitFieldVisibilityConverter = new LimitFieldVisibilityConverter();
Style dynamicPercentageFieldCell = this.FindResource("DynamicPercentageFieldCell") as Style;

foreach (var checkType in AggLimitsCheckTypeMetaData.CheckTypeMetaDataList)
        {
          foreach (var level in AggLimitsCheckTypeMetaData.CheckLevels)
          {
           
            var field = new UnboundField
            {
              Label = string.Format("{0} [%]", checkType.CheckType),
              Name = checkType.CheckType,
              BindingPath = new PropertyPath(checkType.CheckType + "Utilization"),
              Converter=limitConverter,
              Tag = checkType.Tag,
              Settings =
              {
                AllowSummaries=false,
                CellValuePresenterStyle = dynamicPercentageFieldCell
              }
            };
            var multiBinding = new MultiBinding();
            multiBinding.Converter = limitFieldVisibilityConverter;
            multiBinding.ConverterParameter = checkType.CheckType + "currValue";
            multiBinding.Bindings.Add(new Binding(".") { Source = ViewModel });
            multiBinding.Bindings.Add(new Binding("FieldVisibilityChanged") { Source = ViewModel });

            multiBinding.NotifyOnSourceUpdated = true;

            //field.SetBinding(UnboundField.VisibilityProperty, multiBinding); //HOW DO I SET THE ABOVE CREATED MULTI BINDING FOR THE VISIBILITY FIELD ??

            hotBucketFieldLayout.Fields.Insert(fieldPosition++, field);
          }
        }

 Any help is greatly appreciated

Thanks
