如何根据条件更改数据网格视图中的文本前颜色 [英] how to change the text fore color in datagrid view based on condition

问题描述

public void view_load_tenthclass_marks（）

{

//自动调整列大小的代码

dataGridView3.AutoResizeColumns（）;

dataGridView3.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.AllCells;





ConnectionStringSettings consettings = ConfigurationManager.ConnectionStrings [smssms];

string connectionString = consettings.ConnectionString;

SqlConnection cn = new SqlConnection（connectionString）;



SqlCommand sqlcmd = new SqlCommand（）;

SqlDataAdapter sda = new SqlDataAdapter（）;

DataTable dt = new DataTable（）;



cn.Open（）;

//传递查询



sqlcmd =新的SqlCommand（@select * from tenthclass_marks ，cn）;

sda = new SqlDataAda pter（sqlcmd）;

//在SQL数据适配器中填充数据

sda.Fill（dt）;

//绑定它在DataGrid视图中

dataGridView3.DataSource = dt;

cn.Close（）;

}

this是我的代码，用于检索所有学生的标记。如果学生得到< 35然后该行颜色应该更改为另一种颜色。如何写？???

public void view_load_tenthclass_marks()
{
//this code for auto resize of columns
dataGridView3.AutoResizeColumns();
dataGridView3.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.AllCells;


ConnectionStringSettings consettings = ConfigurationManager.ConnectionStrings["smssms"];
string connectionString = consettings.ConnectionString;
SqlConnection cn = new SqlConnection(connectionString);

SqlCommand sqlcmd = new SqlCommand();
SqlDataAdapter sda = new SqlDataAdapter();
DataTable dt = new DataTable();

cn.Open();
//pass query

sqlcmd = new SqlCommand(@"select * from tenthclass_marks ", cn);
sda = new SqlDataAdapter(sqlcmd);
//Fill the data in the SQL Data Adapter
sda.Fill(dt);
//Bind it in the DataGrid View
dataGridView3.DataSource = dt;
cn.Close();
}
