  Hi,

  I am having some trouble filling a requirement for a client where they wish to have the detail of a document, in this case it is document lines, have the “identifiers” in one row with a sub-table of properties beneath these identifiers.

  I have created a SectionReport which has a row of TextBox controls that are databound using the DataField on each textbox. Beneath this row is a SubReport that is bound to another SectionReport. This SubReport is populated like so using the detail_format() of the parent report.

  private void detail_Format(object sender, EventArgs e) 
  {
  	if(_LineDetail != null && _LineDetail.Any() && long.TryParse(this.Fields["ID"].Value.ToString(), out long lineID))
  	{
  		var LineDetails = _LineDetail.Where(ld => ld.DocumentLineID == lineID);
  		if (LineDetails != null && LineDetails.Any())
  		{
  			LineDetail.Visible = true;
  			var lineDetail = new LineDetail(LineDetails);
  			LineDetail.Report = lineDetail;
  			LineDetail.Report.DataSource = LineDetails.CopyToDataTable();
  			LineDetail.Report.Run();
  		}
  		else
  		{
  			LineDetail.Visible = false;
  		}
  	}
  	else
  	{
  		LineDetail.Visible = false;
  	}
  }

  The result is that the header of the SubReport is displayed, but the detail of the SubReport is not displayed. I have checked that the property CanGrow is set to true and the detail section of the parent report can also grow to accommodate, there is definitely space for it. I have also checked the data I am passing to the DataSource of the SubReport is valid and contains elements.

  Is there something I am missing here to get this detail to render?

  Thanks

  Hi Matthew,

  It would be difficult to comment upon the cause of the issue without actually going through a replicating sample, could you please share a stripped-down sample that replicates the issue so we can test the same on our end and further investigate the issue?

  Thanks,
