Hi All

I want to create a Column chart showing total number of appointment hours
per staff member
Along side each bar I want to show another series of total number of
working hours per staff member

When I try to drop the 'total' datafield from the 2nd data adaptor
(HaircutsDataSet_Staffrostergraph) on to the 'Series' area on the graph I
get the message
'Cannot add a field from the dataset "HaircutsDataSet_Staffrostergraph to a
dataregion which uses the dataset HaircutsDataSet_Staffappointmenthours"

What am I doing wrong??

regards
Steve

Code....

mystarttime = dtfrom.Value
myendtime = dtto.Value.AddDays(1)

sql = "SELECT SUM(DATEDIFF(hour, a.mytime, a.endtime)) AS total, s.username
"

sql &= "FROM Appointments a INNER JOIN "

sql &= "Staff s ON a.staffnumber = s.staffnumber "

sql &= "WHERE a.myDate < '" & Format(myendtime, "MMM d, yyyy") & "' AND
a.myDate >= '" & Format(mystarttime, "MMM d, yyyy") & "' "

sql &= "GROUP BY s.username"

dtsales = getdata(sql)

sql = "SELECT SUM(DATEDIFF(hour, sr.mystarttime, sr.myendtime)) AS total,
s.username "

sql &= "FROM staffrosterdetail sr INNER JOIN "

sql &= "Staff s ON sr.staffnumber = s.staffnumber "

sql &= "WHERE sr.myDate < '" & Format(myendtime, "MMM d, yyyy") & "' AND
sr.myDate >= '" & Format(mystarttime, "MMM d, yyyy") & "' "

sql &= "GROUP BY s.username"

dtworkinghours = getdata(sql)

ReportViewer1.LocalReport.DataSources.Add(New
Microsoft.Reporting.WinForms.ReportDataSource("HaircutsDataSet_Staffappointmenthours",
dtsales))

ReportViewer1.LocalReport.DataSources.Add(New
Microsoft.Reporting.WinForms.ReportDataSource("HaircutsDataSet_Staffrostergraph",
dtworkinghours))

ReportViewer1.LocalReport.ReportPath = reportpath &
"Staffappointmenthours.rdlc"
 
Hi Steve,

From your description, you're encountering some problem when try draging
two table's fields onto a chart report item inside a VS 2005 client
report(for reportviewer), correct?

According to the steps you mentioned, I think the problem here is due to
the SQL Server SSRS client report (also server report) only allow a single
dataset bound to a given report Item(such as Table, Chart ......). The
"DataSet" here is the SSRS specific dataset rather than .NET ADO.NET
dataset. You can think the "dataset" here a "resultset".

Therefore, for your scenario, if you want to display info on a single chart
from multiple resultset (from backend data storage's perspective), I
suggest you consider use a View to merge the columns in the two resultset
so that bind a single resultset(table in .net dataset) to the chart.

How do you think?

Sincerely,

Steven Cheng
