C#WPF (DataGid学习)
本文主要是介绍C#WPF (DataGid学习)，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！
先看两张图，一个实现自己的效果，一个使用默认的效果：
不多说，上代码。。。
1.转换器
因为里面有个DateTime，要通过转换器转换为对应的字符串。
using System;
using System.Globalization;
using System.Windows.Data;
[ValueConversion(typeof(DateTime), typeof(string))]
public class DateConverter : IValueConverter
{
public string Format { get; set; } = "yyyy-MM-dd HH:mm:ss.fff";
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
DateTime dt = (DateTime)value;
return dt.ToString(Format);
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
return DateTime.Parse(value.ToString());
}
}
2.资源字典
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:WpfApp6">
<FontFamily x:Key="iconFont">/WpfApp6;component/fonts/iconfont/#iconfont</FontFamily>
<FontFamily x:Key="songti">宋体</FontFamily>
<SolidColorBrush x:Key="mainBackground" Color="#B0E2FF" />
<local:DateConverter x:Key="dataConverterFull" />
<local:DateConverter x:Key="dataConverterShort" Format="yyyy-MM-dd HH:mm:ss" />
</ResourceDictionary>
为了实现两个CheckBox的效果，用到了iconFont图标字体

3. 视图模型
namespace WpfApp6
{
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Collections.ObjectModel;
using System.ComponentModel;
public class ProgramListViewModel
{
public ObservableCollection<ProgramStepModel> ProgramModels { get; set; } = new ObservableCollection<ProgramStepModel>();
public bool CanEdit { get; set; } = true;
public ProgramListViewModel()
{
Random random = new Random();
for (int i = 0; i < 30; i++)
{
ProgramModels.Add(new ProgramStepModel { IsQuick = random.Next(2) == 0, Num = i + 1, Name = Tools.RandomName(5, 8), AlterTime = DateTime.Now, IsLock = random.Next(2) == 0 });
}
}
}
public class ProgramStepModel
{
public bool IsQuick { get; set; }
public int Num { get; set; }
public string Name { get; set; }
public Sex Sex { get; set; }
public DateTime AlterTime { get; set; }
public bool IsLock { get; set; }
public override string ToString()
{

}
}
public enum Sex
{
Man,
Woman,
}
public class Tools
{
static Random Random = new Random();
public static string RandomName(int minLen, int maxLen, bool haveNum = true)
{
List<int> listAscii = new List<int>();
if (haveNum)
{
listAscii.AddRange(Enumerable.Range(48, 10));
}
listAscii.AddRange(Enumerable.Range(65, 26));
listAscii.AddRange(Enumerable.Range(97, 26));
return Encoding.ASCII.GetString(listAscii.ConvertAll(t => (byte)t).OrderBy(l => Guid.NewGuid()).Take(Random.Next(minLen, maxLen)).ToArray());
}
}
}

5.DataGrid属性简单数目
- AutoGenerateColumns 获取或设置一个值，该值指示是否自动创建列。当设置为True时(默认为True)，会根据ItemsSource自动创建列；若同时手动创建时，先显示自动创建的列再显示手动创建的列。
- AlternationCount 获取或设置 ItemsControl 中的交替项容器的数目，该控件可使交替容器具有唯一外观。例如：若是设置为3，那么每行的AlternationIndex就是按照 0，1，2，0，1，2...这样排序，我们就可以通过触发器设置对应行的样式了。
- GridLinesVisibility 指示显示哪些网格线，可以不显示，或者显示竖线、横线
- DataGrid目前支持下面这集中类型的列：
DataGridTextColumn 文本类型，在TextBlock元素中显示 DataGridCheckBoxColumn 复选框 DataGridHyperlinkColumn 可单击的链接 DataGridComboxBox 可下拉的ComboBox控件 DataGridTemplateColumn 这种列允许自定义数据模板 -
每个列都有ElementStyle(未处于编辑模式的单元格显示的样式)和EditingElementStyle(呈现的列将显示处于编辑模式下的样式)。
-
只有在编辑模式下修改数据才有效，其他几个类型的列在非编辑模式下是无法修改数据的，但是DataGridCheckBoxColumn可以在非编辑模式下修改，只是显示效果上而已，并不能真正意义上改变了数据，所以当我们设计时要注意这一点。
-
可以通过设置每列的IsReadOnly来控制列信息是否可以修改，但是对于DataGridTemplateColumn无效，需要自行定义变量控制是否可以修改
