我尝试将2维数组绑定到WPF中的DataGrid。我找到了这个库DataGrid2D,但是我犯了一些错误,因为它没有显示正确的结果,而是一个空的网格。
这是我的XAML代码:
.....
xmlns:dataGrid2D="http://gu.se/DataGrid2D"
....
<Grid>
<DataGrid Name="matrix" dataGrid2D:ItemsSource.Array2D="{Binding Data2D}"
dataGrid2D:ItemsSource.ColumnHeadersSource="{Binding ColumnHeaders}"
dataGrid2D:ItemsSource.RowHeadersSource="{Binding RowHeaders}" />
</Grid>
这就是.cs
private String[] _columnHeaders;
public String[] ColumnHeaders
{
get { return _columnHeaders; }
set { _columnHeaders = value; }
}
private String[] _rowHeaders;
public String[] RowHeaders
{
get { return _rowHeaders; }
set { _rowHeaders = value; }
}
private bool[,] _data2D;
public bool[,] Data2D
{
get { return _data2D; }
set { _data2D = value; }
}
String[] columnHeaders = { "A", "B", "C" };
String[] rowHeaders = { "1", "2", "3" };
bool[,] data2D = { { true, true, false }, { true, true, false }, { true, true, false } };
ColumnHeaders = columnHeaders;
RowHeaders = rowHeaders;
Data2D = data2D;
答案 0 :(得分:0)
我能够通过将属性设置器移动到我的viewmodel构造函数中并确保将viewmodel设置为xaml中的datacontext来实现此功能。
视图模型:
public class MainWindowViewModel
{
private String[] _columnHeaders;
public String[] ColumnHeaders
{
get { return _columnHeaders; }
set { _columnHeaders = value; }
}
private String[] _rowHeaders;
public String[] RowHeaders
{
get { return _rowHeaders; }
set { _rowHeaders = value; }
}
private bool[,] _data2D;
public bool[,] Data2D
{
get { return _data2D; }
set { _data2D = value; }
}
String[] columnHeaders = { "A", "B", "C" };
String[] rowHeaders = { "1", "2", "3" };
bool[,] data2D = { { true, true, false }, { true, true, false }, { true, true, false } };
public MainWindowViewModel()
{
ColumnHeaders = columnHeaders;
RowHeaders = rowHeaders;
Data2D = data2D;
}
}
的Xaml:
