Cannot locate resource with ReportViewer for WPF

Whenever I try and drag and drop the Report Viewer WPF component (on my WPF window), i get the following error:

Initialization of 'Telerik.Windows.Controls.RadButton' threw an exception.
"Cannot locate resource: 'themes/expression/dark/rangecontrol.xaml'."

I am using VS2010 with the Telerik Reporting Q1 2011. I followed the instructions for adding the report viewer to a WPF application, but have not been able to get past the above error. Despite referencing all Telerik themes.

Please help.

Retrieving RawData from Report

I would like to dump the raw data that is used to create a report to Excel.
My intent is to be able to dump the raw data that feeds a report, be it a top level report, or a drill - through report (a report called by another report). How can I retrieve the raw data that feeds the currently viewed report?

Telerik Reporting 2011 Q1 5.0.11.603
VS 2008 using WebForms
All reports datasources are SQLDatasource Stored Procedures with the report parameters fed from the application to the report object

The following is the method I am currently using for the top level report only.

Protected Sub btnDumpToExcel_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnDumpToExcel.Click

Dim RunRpt As String = Me.ReportViewer1.Report.Reports(0).Name

Dim tb As New DataTable(RunRpt)

Dim dataConn As New SqlConnection

Select Case RunRpt

Case "evRptBehaviorChange"

Dim report1 As

Snap_EvalReports.evRptBehaviorChange = ReportViewer1.Report.Reports(0)

With report1

Dim xSQLDatasource As Telerik.Reporting.SqlDataSource = .DataSource

Dim SQLConnectionString As String = System.Configuration.ConfigurationManager.ConnectionStrings(xSQLDatasource.ConnectionString).ToString

Dim xSelectCommand As String = xSQLDatasource.SelectCommand

dataConn.ConnectionString = SQLConnectionString

dataConn.Open()

Dim sdc As SqlCommand = New SqlCommand(xSelectCommand, dataConn)

sdc.CommandTimeout = LengthOfTimeOut

sdc.CommandType = CommandType.StoredProcedure 'xSQLDatasource.SelectCommandType

For Each p As Telerik.Reporting.SqlDataSourceParameter In xSQLDatasource.Parameters

Dim xParam As SqlParameter = New SqlParameter(p.Name, p.GetType)

sdc.Parameters.Add(xParam)

Next

' ALTER PROCEDURE [dbo].[StoredProcedure1]

'(@FiscalYearID int=3)

sdc.Parameters.Item("@FiscalYearID").Value = CType(Session("spaFiscalYear"), Integer)

Dim sda As SqlDataAdapter

sda = New SqlDataAdapter(sdc)

sda.Fill(tb)

dataConn.Close()

dataConn = Nothing

XLSExport(tb, RunRpt)

End With

End Select

End Sub

Thank you in advance.

Export only data instead of report while exporting to excel in report viewer

Hi

I am using ReportViewer to display the reports and also to export the reports in the required format. Here i want a change in the existing system such that when user tries to export to excel, instead of displaying the report in the excel, we want to display the underlying data in the excel sheet. Please let me know whether the existing system support this functionality?

Thanks in advance

Silverlight view fails on {word} in text

I have 2 different reports that fail on the Silverlight viewer when I have '{myword}' in the text I'm displaying from a field. The asp.net version shows the correct text.

I get an error:
"The type 'SUNRISE' was not found. [Line: 1 Position: 7039]"

SUNRISE is the text in {SUNRISE} it's at the start of the text if that makes a difference. I'm using version 5.0.11.316

Incorrect information displayed on chart (X-Axis which contains dates)

Hi
I'm having this issue where the information I have in my SQL database is not being reflected on the chart.

My SQL query returns this data below:

raisedBy counter createdon
Risha Wadhwani   13 2010.06.14
Risha Wadhwani   19 2010.06.15
Tufail Khan 4 2010.06.15
Risha Wadhwani   13 2010.06.16

Also see screenshot 'sql.png'

This is the code that I am using to generate the Chart :

private void chart1_NeedDataSource(object sender, EventArgs e)

{

var dataset = new DataSet();

var adapter = new SqlDataAdapter();

var conn =

new SqlConnection("Initial Catalog=****;Data Source=****;User Id=****;Password=****;");

var cmd = new SqlCommand

{

Connection = conn,

CommandType = CommandType.Text,

CommandText =

@"SELECT raisedBy,

COUNT(id) as counter,

createdon FROM

(

SELECT

da.name as raisedBy,

defects.id,

convert(VARCHAR, defects.created_on, 102)

AS

createdon

FROM

defects

LEFT JOIN

[user] da

ON

(defects.raised_by = da.id)

WHERE

defects.id IN(488,490,491,492,493,494,495,496,497,498,499,500,501,502,504,505,506,508,509,511,512,513,514,515,516,517,518,519,520,521,523,524,526,528,529,530,535,536,537,538,539,540,541,542,543,544,545,546,547)

)

table1

GROUP BY

raisedBy,

createdon

ORDER BY createdon ASC"

};

adapter.SelectCommand = cmd;

adapter.Fill(dataset);

DataView view = dataset.Tables[0].DefaultView;

//var chart = sender as Chart;

chart1.PlotArea.XAxis.Appearance.LabelAppearance.RotationAngle = -320;

chart1.PlotArea.XAxis.Appearance.TextAppearance.TextProperties.Color = Color.BlueViolet;

chart1.PlotArea.XAxis.DataLabelsColumn = "createdon";

chart1.DataGroupColumn = "raisedBy";

chart1.PlotArea.XAxis.IsZeroBased = false;

chart1.PlotArea.XAxis.Appearance.ValueFormat = Telerik.Reporting.Charting.Styles.ChartValueFormat.ShortDate;

chart1.PlotArea.XAxis.Appearance.CustomFormat = "MM/dd/yyyy";

chart1.PlotArea.XAxis.LayoutMode = Telerik.Reporting.Charting.Styles.ChartAxisLayoutMode.Between;

chart1.PlotArea.XAxis.LabelStep = 1;

chart1.PlotArea.XAxis.MaxItemsCount = view.Count;

foreach (DataRowView rowView in view)

{

var datedate = DateTime.Parse(rowView.Row.ItemArray[2].ToString());

rowView.Row.ItemArray[2] = datedate;

}

if (chart1 != null) chart1.DataSource = view;

}

And finally, attached is the screenshot to see the Chart that is being rendered.

The problem is that is 'Tufail Khan' column(on the chart) is being displayed under the date '2010.06.14', instead of '2010.06.15' where it should have been, if you look at the result from the SQL result..

Any help on this would be very much appreciated.
Cheers Telerik!
