Hi,

Currently empty data ranges are not displayed in reports. You can set DataRange.Repeat to 1 for the data range to force it to have one instance.

Let me know if this helps.

Try setting DataRange.Repeat to 1 for the empty data ranges that you want to be visible. Make sure that DataRange.DataSource is set to null in this case. You can also set Repeat in the QueryDetails event handler for nested data ranges. In this case set QueryDetailsEventArgs.Details to null.

Can you provide me with a sample with your report and specify which data ranges in this report you want to show or hide?

Code (HTML)
Select All
            <r:DataRange DataSource="{Binding QuestionTable}" Size="100%,100">
                <r:DataRange.ItemTemplate >
                    <DataTemplate >
                        <r:ItemContainer >
                            <r:DataRange  Name="AnswerList" Location="0%,60" Size="100%,20">
                                <r:DataRange.ItemTemplate>
                                    <DataTemplate>
                                        <r:ItemContainer>
                                            <r:Label Location="0%,0" Size="30%,20"  Background="{Binding QTitle}" BorderBrush="#ACE6EF"  BorderThickness="1,0,1,1" Padding="5,0,0,0" Text="[SID]" />

You can handle the QueryDetails event of the report, inspect the sender's name and if it is "EliminationList", do one of the following depending on whether you want to show or hide the range:

  • To hide the range, simply assign an empty IEnumerable (for example new object[] {}) to QueryDetailsEventArgs.Details. This will indicate that the range is empty.
  • To show the range, set Details to null and DataRange.Repeat to 1.

Let me know if this helps.

Meppy

Yeah, it will hide the DataRange, but this will throw exception when exporting to PDF

Hi,

Thanks for your great help, the problem is solved,
but there is still little problem, when the "EliminationList" DataRange is hidden, the area is still exist, like image below

The blank area can be removed?

Hi,

You can try setting the height of the DataRange in question to 0 (that is, set Size to "W,0" where W is your current value for width). If the range has any content, it will be resized accordingly so that the content fits; if it is empty, it should take no space. However, the header of the data range (if any) will still be accounted for.

Regards,
Meppy

Hi,

I set my "AnswerList" and "EliminationList" DataRange size's height to 0, but seem still the same effect.
