【问题描述】：
平均售价。网络数据网格随机显示没有文本的空行。虽然显示的是空行，但在双击空行时，该行中的数据会正确填充到另一个文本框中。
下面是 UI 代码。
<asp:Panel ID="pnlDataControl" runat="server" Enabled="true" EnableViewState="true">
<div class="grdCtl">
<asp:GridView ID="grdlDataControl" runat="server" ShowFooter="True"
AutoGenerateColumns="False" GridLines="None" AllowPaging="True" AllowSorting="True"
Width="100%" BorderColor="Red" BorderWidth="0px" BorderStyle="Solid" EmptyDataText=""
onpageindexchanging="grdlDataControl_PageIndexChanging"
ondatabound="grdlDataControl_DataBound"
onrowdatabound="grdlDataControl_RowDataBound"
onselectedindexchanged="grdlDataControl_SelectedIndexChanged"
onrowcommand="grdlDataControl_RowCommand" style="margin-bottom: 18px;">
<SelectedRowStyle BackColor="Gray" Font-Bold="true" />
<Columns>
<asp:TemplateField HeaderStyle-CssClass="grdHead" HeaderStyle-Wrap="false" ItemStyle-CssClass="" HeaderStyle-Width="10px" ItemStyle-Width="10px">

向我们展示你的代码！

我怀疑这是因为您使用了
TemplateField。如果您不使用任何控件来绑定值，则无需使用它。相反，您可以使用BoundField<asp:BoundField DataField="YourDataField" HeaderText="Your Column Header" />
