无法取消选中网格视图中的复选框VB.NET

Question

这是我的代码，当我运行应用程序时，列中的复选框全部变灰，如果有人知道如何避开，以便能够取消选中/检查那太好了。

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="4" DataSourceID="SqlDataSource1" EmptyDataText="There are no data records to display." ForeColor="#333333" Height="310px" Width="946px">

      <asp:BoundField DataField="Lender" HeaderText="Lender" ControlStyle-CssClass="lenderimg" SortExpression="Lender" FooterStyle-CssClass="lenderimg"> 
<ControlStyle CssClass="lenderimg"></ControlStyle> 

<FooterStyle CssClass="lenderimg"></FooterStyle> 
      </asp:BoundField> 
      <asp:BoundField DataField="MinLoanAmount" HeaderText="Min Loan Amount" SortExpression="MinLoanAmount" /> 
      <asp:BoundField DataField="MaxLoanAmount" HeaderText="Max Loan Amount" SortExpression="MaxLoanAmount" />

您的数据源是'只读'的。

你需要将它配置有插入，更新和删除语句（单击高级...按钮）：

然后你就可以重新连接GridView和其配置为允许编辑。
