公共局部类windows_student_messages_messagedetails:System.Web.UI.Page
{
StudentBLL stuObj =新的StudentBLL();

void loadMessageIndex()
{
DataTable dt = stuObj.getMessageByUser();
int isEmail = int.Parse(dt.Rows [0] ["isEmail"].ToString());
int isSMS = int.Parse(dt.Rows [0] ["isSMS"].ToString());

如果(isEmail == 1)
{
ImgEmail.Visible = true;
rpMessageBody.DataSource = dt;
rpMessageBody.DataBind();
}
}

public partial class windows_student_messages_messagedetails : System.Web.UI.Page
{
StudentBLL stuObj = new StudentBLL();

void loadMessageIndex()
{
DataTable dt = stuObj.getMessageByUser();
int isEmail = int.Parse(dt.Rows[0]["isEmail"].ToString());
int isSMS = int.Parse(dt.Rows[0]["isSMS"].ToString());

if (isEmail == 1)
{
ImgEmail.Visible = true;
rpMessageBody.DataSource = dt;
rpMessageBody.DataBind();
}
}

protected void Page_Load(object sender, EventArgs e)
   {
     loadMessageIndex();
   }
}

推荐答案

尝试此代码

Try this code

protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
      Label objLabel = (Label)e.Item.FindControl("LblEmail");
      if (isEmail == 1)// Your Condition
      {
        objLabel.Visible= true;
      }
}
