最近做一个任务列表的项目，里面有一TaskStatus列，值为0或者1，在用GridView进行数据绑定的时候，转换0为“未完成”，1为“已完成”，并且把相对应的color设置为red和green。可是在进行数据绑定的时候却没有获取到那个值。如果直接显示0和1是可以的。
只是绑定事件的代码
Code
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow && e.Row.RowState != DataControlRowState.Edit)
{
Int32 istatus = Convert.ToInt32(e.Row.Cells[2].Text);//这里的这个e.Row.Cells[2].Text获取到的就是"";,没有值
if (istatus == 0)
{
e.Row.Cells[2].Text = "未完成";
e.Row.Cells[2].Style.Add("color", "red");
}
else if (istatus == 1)
{
e.Row.Cells[2].Text = "已完成";
e.Row.Cells[2].Style.Add("color", "green");
}
}
}
这里是GridView的源码
