Obout网格变为空

Question

我有一个obout网格，现在我只包含了一个column.When，我设置了数据源并绑定了它，网格在运行时显示为空。我之前用普通网格视图(Asp)做了这件事，它工作得很好。

<obout:Grid ID="gvReport" runat="server" Serialize="false" ShowTotalNumberOfPages="false" AllowPaging="true"
        ShowLoadingMessage="false" FolderStyle="~/styles/premiere_blue" AllowPageSizeSelection="false" EnableRecordHover="true"
        AllowGrouping="false" AutoGenerateColumns="false" AllowFiltering="false" FilterType="ProgrammaticOnly"
        AllowAddingRecords="false" AllowColumnReordering="false" AllowRecordSelection="true" AllowMultiRecordSelection="true" ShowRecordsPerPage="false" AllowColumnResizing="true"  ShowColumnsFooter="false" ShowHeader="true" ShowFooter="true" AllowSorting="true" GenerateRecordIds="True" ViewStateMode="Inherit" KeepSelectedRecords="true" CallbackMode="false" 
        EmbedFilterInSortExpression="true" Width="100%" PageSize="10" OnRowDataBound="GridView_RowDataBound" OnDataBound="GridView_DataBound" OnDataSourceNeeded="GridDataSourceNeededEvent">
        <ScrollingSettings ScrollHeight="260" EnableVirtualScrolling="true" UsePagingForVirtualScrolling="true"   /><Columns>
            <obout:Column ID="colName" DataField="Name" Width="200px" Wrap="true" HeaderText="Content Name"  
                            ShowFilterCriterias="false">
                <TemplateSettings FilterTemplateId="tplNameFilter" />
                <FilterOptions>
                <obout:FilterOption IsDefault="true" Type="Contains" />
                </FilterOptions>
            </obout:Column>
        </Columns>
        <Templates>
            <obout:GridTemplate runat="server" ID="tplNameFilter" ControlID="NameFilter">
            <Template>
                <obout:OboutTextBox runat="server" ID="NameFilter" Width="100%">                                            
                </obout:OboutTextBox>
            </Template>
            </obout:GridTemplate>

        </Templates>
        <TemplateSettings HeadingTemplateId="tplHeading" />       
        <PagingSettings PageSizeSelectorPosition="Bottom" Position="Bottom" ShowRecordsCount="True"  />
        <FilteringSettings InitialState="Hidden" FilterPosition="Top" FilterLinksPosition="Top" />                        
    </obout:Grid>

代码：

gvReport.DataSource = reportData;
gvReport.DataBind();

在调试时，表有所有的值，但是它们没有被赋值给grid.Previously而不是obout，我有一个正常的网格视图，它工作得很好。

您必须删除OnDataSourceNeeded="GridDataSourceNeededEvent“您不能将OnDataSourceNeeded事件与gvReport.DataSource一起删除
