使用Membership检查CheckBox

Question

我有一个GirdView监听我的系统中使用ASP:NET成员资格的所有活跃用户。我想有一个CheckBox，可以选择或不取决于是否一个特定的用户是批准或没有。使用事件处理程序RowDataBound时，我的脚本无法工作。在合适的案例中选择CheckBox有什么想法吗？

感谢您的宝贵时间:-)

        protected void uxUserListDisplayer_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        // Check or Uncheck a CheckBox depending if user is Approved
        switch (e.Row.RowType)
        {
            // In case type of row is DataRow (a data row of GridView) 
            case DataControlRowType.DataRow:
                // Create an object of type MembershipUser for row bounded (Users)
                MembershipUser myUser = (MembershipUser)e.Row.DataItem;
                // Find out the edit button "uxLinkEditButton" and create an object for it
                LinkButton editButton = (LinkButton)e.Row.FindControl("uxLinkEditButton");
                // Find out the checkbox "uxActiveCheckBoxSelector" and create an object for it
                CheckBox activeCheckBox = (CheckBox)e.Row.FindControl("uxActiveCheckBoxSelector");
                // Check if the Object type MembershipUser for a User is approved or not
                if (myUser.IsApproved == true)
                {
                    activeCheckBox.Checked = true; // Checkbox is checked
                }
                else
                {
                    activeCheckBox.Checked = false; // Checkbox is unchecked
                }
                break;
        }
    }

Answer 1

MembershipUser myUser = (MembershipUser)e.Row.DataItem;
CheckBox activeCheckBox = (CheckBox)e.Row.FindControl("uxActiveCheckBoxSelector");
activeCheckBox.Checked = myUser.IsApproved;

希望这能有所帮助

Answer 2

您必须将myUser变量更改为MembershipUser引用；默认情况下，对象没有定义属性...

HTH。
