collapse (hide) the details section

[Dragoljub]

I just want to share this with everyone. Here is how I managed to remove the "empty space" in the details section, so the group data is next to one another.

This code is inside a detail.ItemDataBound event, so "sender" is a Processing.DetailSection object, and based on one of DataItem's attributes I hide all the Items and the section itself.

Dim section As Processing.DetailSection = CType(sender, Processing.DetailSection)

Dim rv As DataRowView = CType(section.DataItem, DataRowView)
If CType(rv.Row("TagCount"), Integer) = 0 Then
    For i As Integer = 0 To section.Items.Count - 1
        section.Items(i).Visible = False
    Next
    section.Visible = False
End If

Hi Dragoljub,

Your approach is right but there is no need for setting Visible=False for all child items of the detail section.

The same effect can be accomplished by setting Visible=False of the detail section in Design time. Furthermore, you can remove detail section manually from the Designer generated code (there is no design time support for this) and the report should continue to work.

This was a specific case of report where not all of the groups contained "details". So this had to be done runtime, on databound event for each detail section "instance".

If I were to hide the details section in the designer, or remove it from the designer generated code, that would change the definiton of the report and it would affect the whole report.

I removed the loop where all the items were set to be invisible, and it works as you said. Only the section has to be set to invisible.

Thanks,
Dragoljub
