我正在创建一个cookie并在成功登录后存储用户名的值.如何在网站打开时访问cookie.如果cookie存在,我想填写cookie值的用户名文本框.以及如何解密该值以获取用户名.我通过从数据库获取用户详细信息来进行服务器端验证.我正在使用vs 2010与c#

FormsAuthenticationTicket tkt;
string cookiestr;
HttpCookie ck;
tkt = new FormsAuthenticationTicket(1, txtUserName.Value, DateTime.Now,
    DateTime.Now.AddYears(1), chk_Rememberme.Checked, "User Email");
cookiestr = FormsAuthentication.Encrypt(tkt);
ck = new HttpCookie(FormsAuthentication.FormsCookieName, cookiestr);

if (chk_Rememberme.Checked)
{
    ck.Expires = tkt.Expiration;
    ck.Path = FormsAuthentication.FormsCookiePath;
    Response.Cookies.Add(ck);
}

创建cookie,名称为.YAFNET_Authentication,内容已加密

Webconfig:

  <forms name=".YAFNET_Authentication" loginUrl="Home.aspx"
  protection="All" timeout="15000" cookieless="UseCookies"/>

我已将文件上传添加到我的asp.net网站.但是,我想限制用户可以选择的文件类型.例如,我只有用户选择mp3文件.如何在文件上传中添加过滤器,以便仅显示所选文件夹中的mp3文件？

 <asp:FileUpload ID="FileUpload1" runat="server" />
 <asp:Button ID="btnAudUpload" Text="Upload" CssClass="btncssUpload" OnClick="btnAudUpload_Click" runat="server" />

<asp:GridView ID="Grid_Organisationtable" runat="server"  CssClass="string"
             SelectedIndex="0" DataKeyNames="OrganisationID"
            ShowHeaderWhenEmpty="True" OnRowDeleting="Grid_Organisationtable_RowDeleting" OnRowEditing="Grid_Organisationtable_RowEditing"
            AutoGenerateColumns="false" Height="95px" Width="492px">     
<Columns>
                   <asp:TemplateField HeaderText="Edit Controls" ItemStyle-Width="15%">
                        <ItemTemplate>
                            <asp:ImageButton ImageUrl="~/Styles/Images/Edit.jpg" CommandName="Edit" runat="server"
                                ID="btn_Edit" ToolTip="Edit Organisation" />
     <asp:LinkButton ID="LinkButton1" CommandArgument='<%# Eval("OrganisationID") %>' CommandName="Delete" runat="server">delete</asp:LinkButton>
     </ItemTemplate>
                        <ItemStyle Width="15%" />
                    </asp:TemplateField>

我在网格视图中有一个链接按钮从网格中删除一行,我想将图像添加到链接按钮而不是文本删除.如何将图像添加到链接按钮.我不想使用图像按钮.谢谢.

我正在进行查询以从tbl_message表中获取Title和RespondBY,我想在对数据绑定到转发器之前解密Title.如何在执行数据绑定之前访问标题值.

string MysqlStatement = "SELECT Title, RespondBy  FROM tbl_message  WHERE tbl_message.MsgID = @MsgID";

using (DataServer server = new DataServer())
{
    MySqlParameter[] param = new MySqlParameter[1];
    param[0] = new MySqlParameter("@MsgID", MySqlDbType.Int32);
    param[0].Value = MessageID;
    command.Parameters.AddWithValue("@MsgID", MessageID);
    ds = server.ExecuteQuery(CommandType.Text, MysqlStatement, param);
}
rptList.DataSource = ds;
rptList.DataBind();


  <table style="width: 498px; color: #F5F5F5;">
        <asp:Repeater ID="rptList" runat="server">

            </HeaderTemplate>
            <ItemTemplate>
                <tr>
                    <td width="15%">
                        <b>Subject</b>
                    </td>
                    <td width="60%">
                        <asp:Label ID="lbl_Subj" runat="server" Text='<%#Eval("Title")%>' />
                    </td>
                </tr>

我使用更新面板进行部分回发,我有两个文本框,一个在更新面板外面,一个在内部,当我从下拉列表中选择其他内容并尝试打开txt_RespondBy文本框内的日历时它没有显示,但是文本框外部更新面板显示日历.为什么Javascript在部分回发后无法在更新面板内工作

int topID = 0;
string TopIDQuery = "Select TopID from tbl_Organisation where OrganisationID=@OrgID";

paramet[0] = new MySqlParameter("@OrgID", MySqlDbType.Int32);
paramet[0].Value = OrgID;

reader = server.ExecuteReader(CommandType.Text, TopIDQuery, paramet);

while (reader.Read())
{
    topID = Convert.ToInt32(reader["TopID"]);
}

reader.Close();

我正在topID从表中读取,当TopID为null时,我想保留topID为0,但由于它为null,因此抛出错误,如何在topIDnull 时处理此错误

<asp:CheckBoxList ID="ckl_EditRole" DataValueField="RoleName" runat="server">
                                    </asp:CheckBoxList>
public void BindListBoxPermission(int field)
    {
        MySqlCommand command = new MySqlCommand();
        DataSet ds = new DataSet();
        int newOrgID = field;
        string MysqlStatement = "SELECT RoleName from tbl_Role Where RoleID >1 order by RoleID desc";
        MySqlParameter[] param = new MySqlParameter[0];
        ds = server.ExecuteQuery(CommandType.Text, MysqlStatement, param);
        ckl_EditRole.DataSource = ds;
        ckl_EditRole.DataBind();
    }

对于每个项目,工具提示是不同的,因为管理工具提示是创建用户而对于用户工具提示是创建消息.如何为复选框内的每个项添加工具提示

UserID      UserName       ParentID      TopID
  1         abc            Null           Null
  2         edf             1             1
  3         gef             1             1

TopID和ParentID来自userID

我想获得用户记录及其子和子记录.这里userid1是root,其子节点是userid2和userid 3.所以如果用户id是1,我必须显示从userid 1到userid 6的所有记录,因为所有记录都是root的子节点和SUbchild.类似地,对于userid3,如果用户标识是3,我必须显示userid3及其子Userid 4和Userid用户4 Userid5

输出应该是

Userid  Username
3          gef
4          huj
5          jdi

我将了解userid和topID,以便我如何进行查询以实现上述结果.

SELECT UserID, UserName  FROM tbl_User WHERE ParentID=3 OR UserID=3 And TopID=1;

通过上面的查询,我能够显示用户ID 3和用户ID 4我无法显示用户ID 5,其中有种类.需要帮忙.谢谢

我有一个文本编辑器,在将格式应用于文本后,我会在单击按钮时显示文本.我希望文本显示在文本编辑器中应用的所有格式.

 lbl_Subject.Text = Server.HtmlEncode(formattedtext);

但它不会以应用的格式显示,而是显示为

<p> This is Para 1</p> <p> this is Para 2</p> <p> <strong>this is bold</strong></p>

如何显示文本编辑器中应用的所有格式的文本

更新我试用文字

结果是

<p> This is Para 1</p> <p> this is Para 2</p> <p> <strong>this is bold</strong></p>
