Error using Grid
posted

Hello,

I saw the same questions on this forum but they have had not replies so I'm asking the question again.

This is what I get when try to run app with grid:

The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).

I set DataSource property from codebehind and data source is a simple dataset. 

Any ideas? I use v10.3

Thank you.

    I am getting this same error.  This is my markup and im binding to a anonymous type, but it shouldn't matter.

      <div align="center" style="width: 100%" >
                    <table>
                        <ig:WebGroupBox ID="wgbPayOnInvoice" runat="server" Text="Pay On Invoice" Width="98%">
                            <Template>
                       
                             <ig:WebDataGrid ID="wdgPayOnInvoice" DataKeyFields="IKey" runat="server" AutoGenerateColumns="true"
                                    Height="350px" Width="100%">
                                    <Columns>
                                        <ig:BoundDataField Key="IKey" DataFieldName="IKey" Hidden="true" />
                                        <ig:BoundDataField Key="BillNumber" DataFieldName="BillNumber">
                                            <Header Text="Bill Number" />
                                        </ig:BoundDataField>
                                        <ig:BoundDataField Key="LabCode" DataFieldName="LabCode">
                                            <Header Text="Lab" />
                                        </ig:BoundDataField>
                                        <ig:BoundDataField Key="InvoiceNumber" DataFieldName="InvoiceNumber">
                                            <Header Text="Invoice Number" />
                                        </ig:BoundDataField>
                                        <ig:BoundDataField Key="TransactionAmount" DataFieldName="TransactionAmount" DataFormatString="{0:C0}">
                                            <Header Text="Total" />
                                        </ig:BoundDataField>
                                        <ig:BoundDataField Key="Balance" DataFieldName="Balance" DataFormatString="{0:C0}">
                                            <Header Text="Balance" />
                                        </ig:BoundDataField>
                                    </Columns>
                                </ig:WebDataGrid>              
                            </Template>
                        </ig:WebGroupBox>
                    </table>
                </div>
