我有正在显示数据的gridview
Name marks old marks new salaryold salarynew
sasi 55 78 23000 45000
kiran 67 45 35000 20000
peter 23 23 10000 10000
我想要的是，如果旧值与新值不同，我想使用不同的颜色，将旧值的颜色设为绿色，将新值的颜色设为红色，如果没有变化，则将绿色都设为绿色。在Rowdatabound其他事件中该怎么办？
这应该可以做到（很抱歉，这台计算机上没有VS）。
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
//Proper input validation should be done here. i.e. empty string etc
var oldSalary = Convert.ToInt32(e.Row.Cells[3].Text);
var newSalary = Convert.ToInt32(e.Row.Cells[4].Text);
if(oldSalary == newSalary){
e.Row.Cells[3].ForeColor = Color.FromName("green");
e.Row.Cells[4].ForeColor = Color.FromName("green");
}
else{
e.Row.Cells[3].ForeColor = Color.FromName("green");
e.Row.Cells[4].ForeColor = Color.FromName("red");
}
}
}
或者
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
var lblOldSalary = e.Row.FindControl("lblOldSalary") as Label;
var lblNewSalary = e.Row.FindControl("lblNewSalary") as Label;
//Proper input validation should be done here. i.e. empty string etc
var oldSalary = Convert.ToInt32(lblOldSalary.Text);
var newSalary = Convert.ToInt32(lblNewSalary.Text);
if(oldSalary == newSalary){
lblOldSalary.ForeColor = Color.FromName("green");
lblNewSalary.ForeColor = Color.FromName("green");
}
else{
lblOldSalary.ForeColor = Color.FromName("green");
lblNewSalary.ForeColor = Color.FromName("red");
}
}
}
