How to add Hierarchical Grid in a Report
posted

I have a generate a PDF report from data I am getting from web service. Based on some certain conditions, the data can be nested where schema is changed in both tables. The problem is when I try to add the nested table, it basically creates 2 set of tables, First it adds the main table and below this table, all child table rows are added together. My code is as:

//add cell for row
for (var i = 0; i < props.Length; i++)
{
if (props[i].Name == "ChildGrid" && gridCols[i].ChildGridColumns.Length > 0)
{
var childGrid = item?.GetType().GetProperty("ChildGrid")?.GetValue(item, null);
if (childGrid != null)
{
IEnumerable lst = ((IEnumerable)childGrid).Cast<object>().ToList();
AddChildGridToReport(lst, gridCols[i].ChildGridColumns);
}
}
else
{
var dt = props[i].GetValue(item, null);

//update class code with new value
if (ReportFor == "Consist/Inventory" && props[i].Name == "ClassCode")
clsCode = dt?.ToString();

AddGridRowCell(tableRow, props[i], dt?.ToString(), gridCols[i], cellPattern);
}
}


private void AddChildGridToReport(object itemList, ColumnProperties[] gc = null)
{
//table
IGrid table = section.AddGrid();
table.Borders = bordersStyle;
table.Width = new RelativeWidth(100);

IGridRow tableRow;
Background cellBgColor = new Background(Colors.White);
Background cellAltBgColor = new Background(new Color(252, 252, 252));
int j = 0;

IGridHeader header = table.Header;
header.Repeat = true;
for (var i = 0; i < gc.Length; i++)
{
IGridColumn gridCol = table.AddColumn();
gridCol.Width = new RelativeWidth(gc[i].Width);

AddGridHeader(header, gc[i]);
}

//define cell pattern/style
GridCellPattern cellPattern = new GridCellPattern()
{
Paddings = cellPaddings,
Borders = bordersStyle,
};
cellPattern.Alignment.Vertical = Alignment.Middle;

//convert object to IEnumerable
var items = (IEnumerable)itemList;
foreach (var item in items)
{

PropertyInfo[] props = item.GetType().GetProperties();

tableRow = table.AddRow();
cellPattern.Background = (j % 2 == 0) ? cellBgColor : cellAltBgColor;

for (var i = 0; i < props.Length; i++)
{
//AddRowCell(tableRow, cellBackgroundColor, gc[i], props[i]);
var dt = props[i].GetValue(item, null);
AddGridRowCell(tableRow, props[i], dt.ToString(), gc[i], cellPattern);
}
j++;
}
}

    Hello Sarojanand,

    Can you please share a little more details on your scenario:

    -    Are you using the Infragistics Reporting which creates an .igr file for the report?
    -    Which is the platform you are working with?
    -    Which version of the Infragistics product you are using?

    Thank you.
