在GridView中获取ASP.NET HyperLinkField的文本

Question

我正在尝试在GridView的OnRowDelete事件中获取HyperLinkField的文本(HyperLinkField的文本是我想删除的行的主键).我知道您无法使用我下面的代码获取文本; 它仅适用于BoundFields(对于HyperLinkFields,字符串为"").但是,我一直无法找到获得此文本的工作答案.如何从HyperLinkField获取显示的文本？(VS2010 w/ASP.NET 4.0和C#)

谢谢阅读!

GridView设计

        <asp:GridView ID="teamGridView" runat="server" CssClass="gridView" RowStyle-CssClass="rowStyle"
        AlternatingRowStyle-CssClass="altRowStyle" HeaderStyle-CssClass="viewsHeader"
        OnRowEditing="Team_OnRowEditing" OnRowDeleting="Team_OnRowDeleting" OnRowUpdating="Team_OnRowUpdating"
        OnRowCancelingEdit="Team_OnRowCancelingEdit">
        <Columns>
            <asp:HyperLinkField HeaderText="Team Name" DataTextField="Team Name" DataNavigateUrlFields="Team Name"
                DataNavigateUrlFormatString="Teams.aspx?Team_Name={0}" />
            <asp:BoundField HeaderText="Team Captain" DataField="Team Captains" />
            <asp:CommandField Visible="false" HeaderText="Commands" ShowEditButton="true" ShowDeleteButton="true" />
        </Columns>
    </asp:GridView>

GridView填充代码

    using (SqlConnection connection = new SqlConnection(WebConfigurationManager.ConnectionStrings["***"].ConnectionString))
        {
            // Initialize GridView and data
            teamGridView.AutoGenerateColumns = false;
            if (Convert.ToInt32(Session["UserLevel"]) > 0)
            {

                teamGridView.Columns[2].Visible = true;
            }
            SqlDataAdapter teamDataAdapter = new SqlDataAdapter();
            DataSet teamDataSet = new DataSet();
            if (Request["Team_Name"] == null)
            {
                // Show the list of teams if no specific team is requested
                teamDataAdapter.SelectCommand = new SqlCommand("[Team Select]", connection);
                teamDataAdapter.SelectCommand.CommandType = CommandType.StoredProcedure;
                teamDataAdapter.Fill(teamDataSet);
                teamGridView.DataSource = teamDataSet;
                teamGridView.DataBind();
            }
}

GridView OnRowDeleting代码

        using (SqlConnection connection = new SqlConnection(WebConfigurationManager.ConnectionStrings["***"].ConnectionString))
    {
        SqlCommand teamDeleteCommand = new SqlCommand("[Team Delete]", connection);
        teamDeleteCommand.CommandType = CommandType.StoredProcedure;
        teamDeleteCommand.Parameters.Add("TeamName", SqlDbType.NVarChar, 50);
        teamDeleteCommand.Parameters[0].Value = teamGridView.Rows[e.RowIndex].Cells[0].Text;
        Response.Write(teamDeleteCommand.Parameters[0].Value);
        try
        {
            connection.Open();
            teamDeleteCommand.ExecuteNonQuery();
        }
        catch (SqlException ex)
        {
            throw new Exception("Team Deletion Error");
        }
    }

代替

teamGridView.Rows[e.RowIndex].Cells[0].Text;

尝试

( (HyperLink) teamGridView.Rows[e.RowIndex].Cells[0].Controls[0] ).Text

无法避免建议您改变将所有SQL直接放在页面中的方式.尝试依靠N层开发.MSDN和asp.NET网站以及channel9.msdn都有很好的视频开头.另外,http://weblogs.asp.net/scottgu
