将模板列添加到radgrid会导致网格UI问题

Question

这是我的网格，当我删除模板按钮网格功能良好，但当模板按钮包括网格不能很好地加载和ui有点破坏，所有的数据出现在一个链接字符串框内当模板按钮到位:

<telerik:RadGrid OnItemCreated="gvClients_ItemCreated" runat="server" ID="gvClients" ClientSettings-EnablePostBackOnRowClick="true" CellSpacing="0" GridLines="None" Skin="Glow" DataSourceID="SqlDataSource1" AllowPaging="True" AllowSorting="True" OnSelectedIndexChanged="gvClients_SelectedIndexChanged" OnDataBound="gvClients_DataBound" AutoGenerateColumns="False">

Answer 1

我不知道问题是什么，但在创建新的解决方案并将相同的源文件复制到新的解决方案后，问题似乎已经解决了。

谢谢不管怎样!

Answer 2

我像下面一样添加了templateccolumn(没有btnDownload_Command)，它正确地呈现了。是文本属性中使用的特殊字符吗?

    <telerik:GridTemplateColumn FilterControlAltText="Filter TemplateColumn column" HeaderText="t" UniqueName="downloadbutton">
        <ItemTemplate>
            <telerik:RadButton ID="btnDownload" runat="server" Text="HeaderName" CommandArgument="<%#Container.ItemIndex %>" >
            </telerik:RadButton>
        </ItemTemplate>
    </telerik:GridTemplateColumn>
