<h1>
CrossTab.aspx Page
</h1>
<p>
<b>Description:</b> The CrossTab.aspx page shows a quarterly
breakdown of sales based on geographical region. It also displays the totals
for each region, the totals for each month within the quarter, and the total
for the whole quarter.
</p>
<p>
<strong>Overview:</strong> The CrossTab Report shows totals for
each region in the footer of the Datagrid. The totals for each month of the
quarter are shown in the rightmost column. The grand total for the quarter is
calculated and displayed in the bottom right corner.
</p>
<p>
<img src="../images/1x1.gif" width="25"> <img src="../images/crosstabtotals.png">
</p>
<p>This report uses the same technique of grouping related data that is used in the
Tabular report (in this case, grouping sales data by quarter). The grouping is
done by nesting a DataGrid control inside of a DataList control.
</p>
<p>
Since the data is time-based, to provide better performance the reports are
filtered by year.</p>
<p>
<strong>Implementation Notes: </strong> As the Datagrids for each
quarter are being databound, the running totals are summed.
</p>
<pre>
//*********************************************************************
//
// The SumItems event handler is for the OnItemDataBound event of the datagrids for each quarter.
// It adds running totals for each region for a particular quarter.
// It also adds the sum totals fo the regions of the quarter as well.
//
//*********************************************************************
protected void SumItems(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
// sum up the data in the columns as the datagrid is databinding
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
// get the sales value for eastern region
double eastern = Convert.ToDouble(e.Item.Cells[1].Text);
// add sales value to the running total
_eastern += eastern;
// format to display sales value as currency
e.Item.Cells[1].Text = string.Format("{0:c}", eastern);
double western = Convert.ToDouble(e.Item.Cells[2].Text);
_western += western;
e.Item.Cells[2].Text = string.Format("{0:c}", western);
double southern = Convert.ToDouble(e.Item.Cells[3].Text);
_southern += southern;
e.Item.Cells[3].Text = string.Format("{0:c}", southern);
double northern = Convert.ToDouble(e.Item.Cells[4].Text);
_northern += northern;
e.Item.Cells[4].Text = string.Format("{0:c}", northern);
double totals = Convert.ToDouble(e.Item.Cells[5].Text);
_totals += totals;
e.Item.Cells[5].Text = string.Format("{0:c}", totals);
}
else if(e.Item.ItemType == ListItemType.Footer )
{
// display our summations in footer
e.Item.Cells[0].Text = "Totals";
e.Item.Cells[0].HorizontalAlign = HorizontalAlign.Left;
e.Item.Cells[1].Text = string.Format("{0:c}", _eastern);
e.Item.Cells[2].Text = string.Format("{0:c}", _western);
e.Item.Cells[3].Text = string.Format("{0:c}", _southern);
e.Item.Cells[4].Text = string.Format("{0:c}", _northern);
e.Item.Cells[5].Text = string.Format("{0:c}", _totals);
// resest the running totals for next datagrid
_eastern = 0;
_western = 0;
_southern = 0;
_northern = 0;
_totals = 0;
}
}
</pre>
<p>
To group the related data, a DataGrid control is nested inside of a DataList
control. The DataGrid control is used here since it is more flexible
to format the look and feel of it.
</p>
<p>
<img src="../images/1x1.gif" width="25"> <img src="../images/crosstabnestedcontrols.png">
</p>
<p>The filter by year is done by calling the GetRegionSales method with the
selected year filter.</p>
<pre>
protected SalesReportCollection GetQuarterDetails(int quarter)
{
return SalesReport.GetRegionSales(quarter, Convert.ToInt32(YearDropDownList.SelectedItem.Value));
}
</pre>
