这似乎很简单,但我似乎无法弄清楚!我试图让 2-way 数据绑定在 ASP.net 页面上工作,其中一个复选框作为列之一。如何从 gridview 中获取更新的值(来自复选框)??????
这是我的数据类型:
[Serializable]
public class UserRequirements
{
public string FirstName { get; set; }
public string LastName { get; set; }
public string UserId { get; set; }
public string Email { get; set; }
public bool ThingRequired { get; set; }
}
我的标记看起来像这样:
<form id="form1" method="post" runat="server" >
<asp:GridView ID="UserTable" runat="server" AutoGenerateColumns="false" >
<Columns>
...
<asp:TemplateField HeaderText="Required ?">
<ItemTemplate>
<asp:CheckBox id="chkBox1" runat="server" on
Text ="Required"
checked='<%# DataBinder.Eval(Container.DataItem,"ThingRequired") %>'>
</asp:CheckBox>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
<asp:Button id="thebutton" Text="Save Changes" OnClick="UpdateRequirements" runat="server" CausesValidation=false />
</form>
我背后的代码如下所示:
List<UserRequirements > _userList = new List<UserRequirements >();
protected void Page_Load(object sender, EventArgs e)
{
_userList = data_layer.GetUserRequirments();
this.UserTable.DataSource = _userList;
this.UserTable.DataBind();
}
最终,我会调用这样的东西,但我不知道应该去哪里或者如何从 gridview 中取回值:
void UpdateRequirements(object sender, EventArgs e)
{
_userList = ???????????? // How do I get the data?
data_layer.UpdateUserRequirements( _userList );
}
