Question

I am working on RDLC reports in asp.net.
I had one datasource for my report. It was working perfectly.
But now I changed it and assigned another datasource to it as well.
here is the code:

<rsweb:ReportViewer ID="rptAdmissionNote" runat="server" Font-Names="Verdana" 
        Font-Size="8pt" Height="100%" Width="100%" 
        InteractiveDeviceInfos="(Collection)" WaitMessageFont-Names="Verdana" 
        WaitMessageFont-Size="14pt">
        <LocalReport ReportPath="Reports\Admission\rptAdmissionNoteReport.rdlc">
            <DataSources>
                <rsweb:ReportDataSource DataSourceId="odsAdmission" Name="DSAdmission" />
                <rsweb:ReportDataSource DataSourceId="odsInitialService" Name="DSInitialService" />
            </DataSources>
        </LocalReport>
    </rsweb:ReportViewer>

    <asp:ObjectDataSource ID="odsAdmission" runat="server" 
        OldValuesParameterFormatString="original_{0}" 
        SelectMethod="SelectAdmissionForReport" 
        TypeName="PrecisionCareBLL.AdmissionBLL.AdmissionLogic">
        <SelectParameters>
            <asp:QueryStringParameter Name="admissionId" QueryStringField="Id" 
                Type="Int32" />
        </SelectParameters>
    </asp:ObjectDataSource>  

    <asp:ObjectDataSource ID="odsInitialService" runat="server" 
        OldValuesParameterFormatString="original_{0}" 
        SelectMethod="SelectAdmissionForReport" 
        TypeName="PrecisionCareBLL.AdmissionBLL.AdmissionLogic">
        <SelectParameters>
            <asp:QueryStringParameter Name="admissionId" QueryStringField="Id" 
                Type="Int32" />
        </SelectParameters>
    </asp:ObjectDataSource>

Still it worked fine and project successfully built.
But when I added another DataSet in RDLC file, I am getting these errors:

Error   27  The rectangle ‘rectAdmission’ and the rectangle ‘rectServicePlanDue’ overlap. Overlapping report items are not supported in all renderers.  

And lots of such errors.
Why it was working fine previously and what happened now?
When I remove newly added dataset from RDLC file, it again works fine.

Please anyone can tell me the reason behind that?

Thank you.

Open the rdlc file.. Go to Report menu ->Data sources. Select the datasource which you newly added and press the Remove button then give Ok.
