如何绑定gridview中数据表的复选框值

Question

我需要弄清楚如何在GridView中绑定CheckBox值,我在GridView中编写了CheckBox.Checked = DataBinder.Eval(Container.DataItem,"IsSubscribed"),但是CheckBox总是被检查,即使IsSubscribed是false也是如此.

Page_Load在页面回发之前,我已经绑定了网格.这是我的代码:

<asp:TemplateField HeaderText="Select"> 
     <ItemTemplate> 
        <asp:CheckBox 
            ID="chkIsSubscribed" runat="server" HeaderText="IsSubscribed" 
            Checked='<%# DataBinder.Eval(Container.DataItem, "IsSubscribed") %>'/>  
     </ItemTemplate> 
</asp:TemplateField>

谢谢.

Answer 1

将此代码作为您的项目模板元素:

<asp:TemplateField HeaderText="Select">
    <ItemTemplate>
        <asp:CheckBox ID="chkIsSubscribed" runat="server" HeaderText="IsSubscribed" 
        Checked='<%#bool.Parse(Eval("IsSubscribed").ToString())%>' />
    </ItemTemplate>
</asp:TemplateField>

Answer 2

<asp:TemplateField HeaderText="Select"> 
     <ItemTemplate> 
        <asp:CheckBox 
          ID="chkIsSubscribed" runat="server" HeaderText="IsSubscribed" 
          Checked='<%#Convert.ToBoolean(Eval("IsSubscribed")) %>'/>  
     </ItemTemplate> 
</asp:TemplateField>

请用这个......
