我有一个带有7个已定义列的填充DataTable(xDataTable) - 我想要用作RowHeader的第一列。
我还有一个DataGrid:
<DataGrid x:Name="DataGridX" ItemsSource="{Binding}" Grid.Row="0"
CanUserAddRows="False" SelectionUnit="Cell" />
然后我设置了DataGrid的DataContext:
DataGridX.DataContext = xDataTable;
这一切都有效 - 但是如何将我的DataGrid的第一列设置为RowHeader?
答案 0 :(得分:7)
使用以下样式(通常情况):
<DataGrid.RowHeaderStyle>
<Style TargetType="{x:Type DataGridRowHeader}">
<Setter Property="Content" Value="{Binding RelativeSource={RelativeSource AncestorType={x:Type DataGrid}},Path=Columns[0].Header,Mode=OneTime}" />
</Style>
</DataGrid.RowHeaderStyle>
如果我们想要单独Row的单独RowHeader,请使用:
<DataGrid.RowStyle>
<Style TargetType="{x:Type DataGridRow}">
<Setter Property="IsSelected" Value="{Binding IsRowSelected}" />
<Setter Property="Header" Value="{Binding Content}" />
</Style>
</DataGrid.RowStyle>
只需根据需要更改上述绑定即可。
如果第一栏是:
<DataGridTextColumn Binding="{Binding Content}" Header="Content"/>
然后删除此列并将此绑定用于标题。

您可以根据需要设置任何标题。只需添加您的列:
DataTable.Columns.Add("I am a Column Header!:)");
让我们看看MVVM示例:
public class YourViewModel : ViewModelBase
{
public YourViewModel()
{
PopulateDataTable();
}
private void PopulateDataTable()
{
var _ds = new DataSet("Test");
employeeDataTable = new DataTable();
employeeDataTable = _ds.Tables.Add("DT");
for (int i = 0; i < 20; i++)
{
//you can set any Header in the following line
employeeDataTable.Columns.Add(i.ToString());
}
for (int i = 0; i < 10; i++)
{
var theRow = employeeDataTable.NewRow();
for (int j = 0; j < 20; j++)
{
theRow[j] = "a";
}
employeeDataTable.Rows.Add(theRow);
}
}
private DataTable employeeDataTable;
public DataTable EmployeeDataTable
{
get { return employeeDataTable; }
set
{
employeeDataTable = value;
OnPropertyChanged("EmployeeDataTable");
}
}
}
您的XAML:
<DataGrid ItemsSource="{Binding EmployeeDataTable}" />

让我们看一下代码隐藏示例:
您的XAML:
<DataGrid Name="dataGrid"/>
您的代码隐藏:
//constructor of the Window
public MainWindow()
{
InitializeComponent();
PopulateDataGrid();
}
DataTable employeeDataTable = new DataTable();
private void PopulateDataGrid()
{
var _ds = new DataSet("Test");
employeeDataTable = _ds.Tables.Add("DT");
for (int i = 0; i < 10; i++)//create columns
{
employeeDataTable.Columns.Add("I am a column!:)");
}
for (int i = 0; i < 50; i++)//fill data to rows
{
var theRow = employeeDataTable.NewRow();
for (int j = 0; j < 10; j++)
{
if (j % 2 == 0)
theRow[j] = "a";
else
theRow[j] = "b";
}
employeeDataTable.Rows.Add(theRow);
}
dataGrid.ItemsSource = employeeDataTable.AsDataView();
}
