如何根据日期更改Gridview颜色 [英] How Do I Change Change Gridview Color Based On Date

问题描述

你好，请你帮我吧..如果日期过去，我想改变gridview行的颜色...我是编程的新手，帮我解决这个问题......

解决方案

试试这个..

  protected   void  GridView1_RowDataBound（ object  sender，GridViewRowEventArgs e）
 {
 
  if （e.Row.RowType == DataControlRowType.DataRow）
 {
 DateTime date =（DateTime）DataBinder。 Eval（e.Row.DataItem，  DateColumnofYourDataSource）; 
  if （DateTime.Now >  date）
 e.Row.BackColor = System.Drawing.Color.Red; 
  else  
 e.Row.BackColor = System.Drawing.Color.Green; 
} 
} 
 

  protected   void  GridView1_RowDataBound（ object  sender，GridViewRowEventArgs e）
 {
 
  if （e.Row.RowType == DataControlRowType.DataRow）
 {
 
 Label lbldate =（Label ）e.Row.FindControl（ 标签的ID）;  //  哪一个包含Gridview中的日期字段 
 
 datetime presentdate; 
 presentdate = System.Datetime.Now.Tostring（）; 
  if （lbldate.text> presentdate）
 {
 
 e.Row.BackColor = System.Drawing.Color .FromName（ ＃ffcdea）; 
} 
 
  else  
 {
 e.Row.BackColor = System.Drawing.Color.FromName （ ＃FFFFFF）; 
} 
 
} 
} 

使用Gridview1_RowDataBound事件



尝试这样（根据您的要求更改代码）： -

  protected   void  GridView1_RowDataBound（ object  sender，GridViewRowEventArgs e）
 {
 
  if （e.Row.RowType == DataControlRowType.DataRow）
 {
  int  dtrslt = DateTime.Compare（e.Row.DataItem（  DATE_COLUMN_NAME），Date.Now ）; 
  if （dtrslt <   0 ）
 e.Row.BackColor = System.Drawing.Color.Red; 
  //  或者对于十六进制颜色 
 e.Row.BackColor = ColorTranslator。 FromHtml（ ＃D1ECC2）; 
  else  
 e.Row.BackColor = System.Drawing.Color.yellow; 
  //  或者对于十六进制颜色 
 e.Row.BackColor = ColorTranslator。 FromHtml（ ＃E7B3B3）
} 
}

解决方案

Try this..

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
       {

           if (e.Row.RowType == DataControlRowType.DataRow)
           {
               DateTime date = (DateTime)DataBinder.Eval(e.Row.DataItem, "DateColumnofYourDataSource")   ;
               if (DateTime.Now > date )
                   e.Row.BackColor = System.Drawing.Color.Red;
               else
                   e.Row.BackColor = System.Drawing.Color.Green;
           }
       }

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{

if (e.Row.RowType == DataControlRowType.DataRow)
{

 Label lbldate= (Label)e.Row.FindControl("id of your label"); //which one contain the date field in Gridview

datetime presentdate;
presentdate=System.Datetime.Now.Tostring();
if (lbldate.text> presentdate)
               {
                  
                   e.Row.BackColor = System.Drawing.Color.FromName("#ffcdea");
               }

else
{
  e.Row.BackColor = System.Drawing.Color.FromName("#FFFFFF");
}

}
}

use Gridview1_RowDataBound event

try like this(change in code as per your requirement):-

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{

    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        int dtrslt = DateTime.Compare(e.Row.DataItem("DATE_COLUMN_NAME"), Date.Now);
        if ( dtrslt < 0)
     e.Row.BackColor = System.Drawing.Color.Red;
                   //Or for hex color
    e.Row.BackColor = ColorTranslator.FromHtml("#D1ECC2");
        else
     e.Row.BackColor = System.Drawing.Color.yellow;
    //Or for hex color
            e.Row.BackColor = ColorTranslator.FromHtml("#E7B3B3")
    }
}
