Hi Dear community! Need help with reporting...
What i need is a simple form that would be display report from one datatable, which will be generated at runtime.
I've read this article "Binding DataSet and Generic *.rdlc Reports to a ReportViewer at Runtime" (http://www.codeproject.com/Articles/13592/Binding-DataSet-and-Generic-rdlc-Reports-to-a-Repo?fid=285487&df=90&mpp=25&noise=3&prof=False&sort=Position&view=Quick&spc=Relaxed&fr=1#xx0xx)
and follow the instructions.
First of all, i've created a Schema file for my DataSet.
DataTable dt = DbAccessLayer.GetTimeReportTable();
dt.TableName = "ReportTable";
DataSet ds = new DataSet();
ds.Tables.Add(dt);
ds.DataSetName = "DataSetTimeReport";
ds.WriteXmlSchema("ds_schema.xsd");So i have 'ds_shema.xsd' file, which i've successfully imported into my project. A new DataSource become available in Data Sources Window, so i'am ready to design report *.rdlc file.
I've added new Report Wizard item, and walk through wizard steps, set up Data Source with my generated dataset and desing very basic report (only drag and drop fields onto Values listbox). Finally i have report.rdlc file.
Then i add new reportViewer control onto my form and button for trigger report loading at runtime.
Here is the code of button click:
DataTable dt = DbAccessLayer.GetTimeReportDataTable() dt.TableName = "ReportTable"; DataSet ds = new DataSet(); ds.Tables.Add(dt); ds.DataSetName = "DataSetTimeReport"; reportViewer1.ProcessingMode = ProcessingMode.Local; reportViewer1.LocalReport.DataSources.Clear(); reportViewer1.LocalReport.DataSources.Add(new ReportDataSource(ds.DataSetName + "_" + dt.TableName, ds.Tables[0])); reportViewer1.LocalReport.ReportPath = @"RDLC\report.rdlc"; reportViewer1.LocalReport.Refresh();
When button clicked reportViewer becomes empty, no error messages.
I've check datatable object, and it has data and not empty.
Here is 'report.rdlc' file content, i've check dataset name and table name, and it all seems correct.
<?xml version="1.0" encoding="utf-8"?><Report xmlns:rd="http://schemas.microsoft.com/SQLServer/reporting/reportdesigner" xmlns="http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition"><DataSources><DataSource Name="DataSetTimeReport"><ConnectionProperties><DataProvider>System.Data.DataSet</DataProvider><ConnectString>/* Local Connection */</ConnectString></ConnectionProperties><rd:DataSourceID>3dc22ca7-a572-4141-a74c-93bd68764616</rd:DataSourceID></DataSource></DataSources><DataSets><DataSet Name="DataSetTimeReport_ReportTable"><Fields> ... some fields definition here, remove to reduce listing size</Fields><Query><DataSourceName>DataSetTimeReport</DataSourceName><CommandText>/* Local Query */</CommandText></Query><rd:DataSetInfo><rd:DataSetName>DataSetTimeReport</rd:DataSetName><rd:TableName>ReportTable</rd:TableName></rd:DataSetInfo></DataSet></DataSets><Body><ReportItems><Tablix Name="Tablix1"><TablixBody> ... some tablix item definitions here, remove to reduce listing size</TablixBody><TablixColumnHierarchy><TablixMembers><TablixMember /><TablixMember /><TablixMember /><TablixMember /><TablixMember /><TablixMember /><TablixMember /><TablixMember /></TablixMembers></TablixColumnHierarchy><TablixRowHierarchy><TablixMembers><TablixMember><KeepWithGroup>After</KeepWithGroup></TablixMember><TablixMember><Group Name="Details" /></TablixMember></TablixMembers></TablixRowHierarchy><DataSetName>DataSetTimeReport_ReportTable</DataSetName><Height>0.5in</Height><Width>8in</Width><Style><Border><Style>None</Style></Border></Style></Tablix></ReportItems><Height>2in</Height><Style /></Body><Width>8in</Width><Page><LeftMargin>1in</LeftMargin><RightMargin>1in</RightMargin><TopMargin>1in</TopMargin><BottomMargin>1in</BottomMargin><Style /></Page><rd:ReportID>44fd6943-7b76-453c-8dd8-cc41dd9343ba</rd:ReportID><rd:ReportUnitType>Inch</rd:ReportUnitType></Report>
