Hi All

推荐答案

我假设您正在使用ASP.Net C#.
为您的GridView创建GridView1_RowDataBound事件.

I am assuming that you are using ASP.Net C#.
Create GridView1_RowDataBound event for your GridView.

if (e.Row.RowType = DataControlRowType.DataRow) 
{     
  //Check your condition here     
  If(Condition True)    
  {         
     e.Row.BackColor = Drawing.Color.Red // This will make row back color red     
  } 
} 

对于Windows应用程序:

For windows application:

void dataGridView1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e) 
{      
    if (e.Value != null)      
    {          
         if (e.Value.Equals(string.Empty))              
            e.CellStyle.BackColor = Color.Green;
         else
            e.CellStyle.BackColor = Color.Blue;
      
    }                
} 

这称为Conditional Formatting.尝试下面的代码，希望它可以帮助您继续前进.

您可以在标记中启用RowDataBound事件

This is called Conditional Formatting. Try the code below hope it helps you move on.

You can enable the RowDataBound Event in the markup

<asp:gridview id="gridview1" runat="server" onrowdatabound="RowDataBound" xmlns:asp="#unknown">

   </asp:gridview>

并将其放在您的 Code-Behind 文件中.

And put this in your Code-Behind file.

protected void RowDataBound(Object sender, GridViewRowEventArgs e)
   {
       if(e.Row.RowType == DataControlRowType.DataRow)
       {
           if(e.Row.RowIndex == 0)
               if(e.Row.Cells[0].Text == string.Empty)
                   e.Row.Cells[0].BackColor = Color.Green;
               else
                   e.Row.Cells[0].BackColor = Color.Blue;
       }
   }
