问题描述

Hello frens，

i有这个问题

我想要做的是我有一个字符串，其中包含tr的id名称，我正在尝试使tr显示为true或false，它们在=server运行。

我的代码看起来像这样

Hello frens,

what i want to do is i have a string that holds the name of the id of the tr and i am trying to make that tr visible true or false which are run at ="server".
my code looks like this

if (dr.HasRows)
                {
                    while (dr.Read())
                    {
                        string id = "tr" + dr["FieldName"].ToString().Replace(" ", "");
                        HtmlTableRow tr = pageMain.FindControl(id) as HtmlTableRow;
                        if (tr != null)
                            tr.Visible = false;


                    }

您好karkiB123，



请查看此解决方案，



为表添加runat =server，如果有任何父标签（panel，div）

Hi karkiB123,

Please check with this solution,

Add runat="server" for table and if any parent tag(panel,div)

if (dr.HasRows)
{
  while (dr.Read())
  {
    string id = "tr" + dr["FieldName"].ToString().Replace(" ", "");
    var table = (HtmlTable)tblName.FindControl(id); //tblName ->Table Name
    if (table != null)
    {
      tr.Visible = false;
    }      
  }
}
