您必须像这样使用网格的
RowDataBound
事件:
创建gv后,首先放置此行:
gv.RowDataBound+=GvOnRowDataBound;
然后按照以下代码操作:
private void GvOnRowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Header)
{
for (int i = 0; i < e.Row.Cells.Count;i++)
{
var customAttributes =
typeof (YourClass).GetProperty(e.Row.Cells[i].Text).CustomAttributes.ToList();
var displayNameAttribute =
customAttributes.FirstOrDefault(
aa => aa.AttributeType.FullName.Equals("System.ComponentModel.DisplayNameAttribute"));
if (displayNameAttribute != null)
e.Row.Cells[i].Text = displayNameAttribute.ConstructorArguments[0].ToString();
}
}
}
private void GvOnRowDataBound(对象发送方,GridViewRowEventArgs e)
{
if(e.Row.RowType==DataControlRowType.Header)
{
for(int i=0;iaa.AttributeType.FullName.Equals(“System.ComponentModel.DisplayNameAttribute”);
if(displayNameAttribute!=null)
e、 Row.Cells[i].Text=displayNameAttribute.ConstructorArguments[0].ToString();
}
}
}
请记住将
YourClass
更改为您的班级名称。谢谢。。。这节省了我很多时间。只有几个观察结果可以帮助其他人:1-在调用DataBind()方法之前调用它。2-要从标题中删除(“),请将代码中的行替换为->e.Row.Cells[i]。Text=displayNameAttribute.ConstructorArguments[0]。Value.ToString();
