C# Can'；无法在datagrid ASP.NET中获取复选框值

我有一个DataGrid，它有用于选择特定用户的复选框。当单击Ok按钮时，我应该获取复选框的状态，如果选中，则获取行的ID。我进入复选框，但值总是选中=false，当然，即使我选中复选框。代码如下：

        <Columns>

            <asp:TemplateColumn HeaderText="Odabir">
                <ItemTemplate>
                    <asp:CheckBox ID="chkVjezba" runat="server" Enabled="true"/>
                </ItemTemplate>
            </asp:TemplateColumn>

            <asp:BoundColumn HeaderText="Vježba" DataField="Naziv"></asp:BoundColumn>

            <asp:TemplateColumn HeaderText="Broj serija">

                    <asp:TextBox ID="brojSerija" runat="server" Width="20px"></asp:TextBox>
                </ItemTemplate>
            </asp:TemplateColumn>

            <asp:TemplateColumn HeaderText="Ocjena 6">

像这样试试

        <Columns>

            <asp:TemplateColumn HeaderText="Odabir">

                CheckBox chkVjezba = (CheckBox)row.FindControl("chkVjezba");

                if (chkVjezba.Checked)
                {
                    //something
                }
            }

        }

您可以在每次回发时进行数据绑定。确保只有在以下情况下才进行数据绑定！Page.IsPostBack.

就是这样！伟大的我刚刚添加了页面加载事件if（！IsPostBack）谢谢，将if（！IsPostBack）添加到页面加载事件解决了问题。@rukfash别忘了标记为答案。谁的答案对您更有帮助
