Hi,

I have bool property ShowDateOfService. Setting true or false value to ShowDateOfService property based on some condition but XamDataGrid column is not visible/hide.

My Code is here:

public class LinkToDocumentViewModel : ViewModelBase

{

 public ObservableCollection<DocumentRow> DocumentsToLink { get; set; }

 public bool ShowDateOfService { get; private set; }

#region Constructor
public LinkToDocumentViewModel(ReferralDocumentLinks referral)
{
ReferralDocumentInformation = referral;
Initialize();
}

public void Initialize()
{

ShowDateOfService =false;

GetSearchedDocuments();

}

private void GetSearchedDocuments()

{

if(basedonDate = 1)

ShowDateOfService =true;

else

ShowDateOfService =false;

}

}

LinkUnlinkToDocument.xmal as below

<igDP:XamDataGrid x:Name="DocumentToLinkGrid" DataSource="{Binding DocumentsToLink}" BorderBrush="Gray" BorderThickness="1" Width="Auto" ScrollViewer.HorizontalScrollBarVisibility="Auto" GroupByAreaLocation="None" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" Margin="0,5,0,0" ScrollingMode="Immediate">

<igDP:Field AllowEdit="False" Name="DateOfService" Label="Date of Service" Width="*" Visibility="{Binding DataContext.ShowDateOfService,Converter={StaticResource             BooleanToVisibilityConverter},RelativeSource={RelativeSource FindAncestor}}">

<igDP:Field.Settings>
<igDP:FieldSettings EditorStyle="{StaticResource DateEntryFormatStyle}"/>
</igDP:Field.Settings>
</igDP:Field>

 </igDP:XamDataGrid>

-------------------------------------------------

I used BooleanToVisibilityConverter for Data grid column and Bind ShowDateOfService value.

But DataGrid column is not hide when i set ShowDateOfService =false.

Please suggest how to hide XamDataGrid column.
