在不单击编辑的情况下，使复选框在ASP.NET GridView上可编辑

<asp:GridView ID="GridView1" runat="server">
    <Columns>
        <asp:TemplateField HeaderText="选择">
            <HeaderTemplate>
                <asp:CheckBox ID="chkSelectAll" runat="server" AutoPostBack="true" OnCheckedChanged="chkSelectAll_CheckedChanged" />
            </HeaderTemplate>
            <ItemTemplate>
                <asp:CheckBox ID="chkSelect" runat="server" />
            </ItemTemplate>
        </asp:TemplateField>
        <!-- 其他列 -->
    </Columns>
</asp:GridView>

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        CheckBox chkSelect = (CheckBox)e.Row.FindControl("chkSelect");
        // 设置复选框选中状态
        chkSelect.Checked = (bool)DataBinder.Eval(e.Row.DataItem, "IsSelected");
        // 设置其他属性
        chkSelect.Enabled = true; // 设置可编辑状态
    }
}

protected void chkSelectAll_CheckedChanged(object sender, EventArgs e)
{
    CheckBox chkSelectAll = (CheckBox)sender;
    foreach (GridViewRow row in GridView1.Rows)
    {
        CheckBox chkSelect = (CheckBox)row.FindControl("chkSelect");
        chkSelect.Checked = chkSelectAll.Checked;
    }
}
