Question

我的数据库中的表有以下几列ID，eventstart，eventend，事件名称

我想事件名称加在上的日期压延机的细胞事件的开始日期，它正在发生

绑定

但是我不能够这样做

以下是我的代码片断

protected void myCal_DayRender1(object sender, DayRenderEventArgs e) 
{ 
    DataSet ds = new DataSet(); 

    SqlDataAdapter cmd = new SqlDataAdapter("Select * FROM event", con); 
    cmd.Fill(ds, "Table"); 
    if (!e.Day.IsOtherMonth) 
    { 
     foreach (DataRow dr in ds.Tables[0].Rows) 
     { 
      if ((dr["eventstart"].ToString() != DBNull.Value.ToString())) 
      { 
       DateTime dtEvent = (DateTime)dr["eventstart"]; 
       if (dtEvent.Equals(e.Day.Date)) 
       { 

        Label lbl = new Label(); 
        lbl.BorderColor = System.Drawing.Color.Black; 
        lbl.BorderStyle = BorderStyle.Double; 
        lbl.Width = 100; 
        lbl.Height = 100; 
        lbl.BackColor = System.Drawing.Color.BlanchedAlmond; 
        lbl.Text = TextBoxName.Text + "" + TextBoxStart.Text + "" + TextBoxEnd.Text; 
        e.Cell.Controls.Add(lbl); 


       } 
      } 
     } 
    } 
    else 
    { 


     } 

}

好了，再次从一开始。现在我想我明白了。您的问题可能是由与迄今为止的时间比较日期引起的。若要仅获取无时间您可以使用dt.Date正如你可以看到下面的日期。你可以考虑装上的，因为性能原因页面加载的所有数据。

DataSet ds = new DataSet();   

protected void Page_Load(object sender, EventArgs e) 
{ 
    //get data 
    using (SqlConnection connection = new SqlConnection(connectionString)) 
    { 
     SqlDataAdapter adapter = new SqlDataAdapter(); 
     adapter.SelectCommand = 
      new SqlCommand("select * from event", connection); 
     adapter.Fill(ds); 
    } 
} 

protected void Calendar1_DayRender(object sender, DayRenderEventArgs e) 
{   
    //mark dates in calendar 
    foreach (DataRow dr in ds.Tables[0].Rows) 
    {   
     DateTime dt = (DateTime)dr.Field<DateTime?>("eventstart"); 

     if (e.Day.Date == dt.Date)   
      {  
       e.Cell.BackColor = System.Drawing.Color.Yellow; 

       //add event lable to day 
       Label lbl = new Label(); 
       lbl.BorderColor = System.Drawing.Color.Black; 
       lbl.BorderStyle = BorderStyle.Double; 
       lbl.BackColor = System.Drawing.Color.BlanchedAlmond; 
       lbl.Text = "Event text"; 
       e.Cell.Controls.Add(lbl);    
      } 
    } 
}
