问题描述
我动态填充 DataGrid
,我也试图使一些列为 CheckBox
列。我这样做:
I'm dynamically filling a DataGrid
and I'm also trying to make some columns as CheckBox
columns. And I'm doing it this way :
DataTable dt = new DataTable();
dt.Columns.Add("First Column", typeof(String));
dt.Columns.Add("Second Column", typeof(Decimal));
dt.Columns.Add("Third Column", typeof(CheckBox));
foreach (var i in Query)
{
List<Object> temp = new List<Object>();
temp.Add(i.FirstValue);
temp.Add(i.SecondValue);
temp.Add(new CheckBox { IsChecked = false});
dt.Rows.Add(temp.ToArray());
}
DataGrid1.ItemsSource = dt.DefaultView;
不幸的是我在DataGrid中看到的是一个 System.Windows.Controls。 CheckBox
,我也尝试了 DataGridCheckBoxColumn
和 DataGridTemplate
,但只有对象的引用去那里。那么,什么是正确的方法把 CheckBox
放在 DataGrid
中。 (我知道如何在 XAML 中执行此操作,但我想知道如何从代码后面做)
Unfortunately what I see in my DataGrid is a System.Windows.Controls.CheckBox
, I've also tried the DataGridCheckBoxColumn
and also DataGridTemplate
but only the object's reference goes there. So what is the right way to put the CheckBox
in the DataGrid
from the code. (I know how to do it in XAML but I wanna know how to do it from the code behind)
推荐答案
将第三列定义为 bool
类型。 WPF应自动将其作为复选框呈现。
Define the third column as type bool
. WPF should automatically render it as a checkbox.
示例:
DataTable dt = new DataTable();
dt.Columns.Add("First Column", typeof(String));
dt.Columns.Add("Second Column", typeof(Decimal));
dt.Columns.Add("Third Column", typeof(bool));
foreach (var i in Query)
{
List<Object> temp = new List<Object>();
temp.Add(i.FirstValue);
temp.Add(i.SecondValue);
temp.Add(false); // false => unchecked, true => checked.
dt.Rows.Add(temp.ToArray());
}
