我定义了一个包含三行的初始表。如果用户选择一行并单击“开始新表”按钮,它将打开一个带有新表的新tabItem。 问题是我不知道如何在DataGrid中选择整行。
C# Code:
//this my initial Table
private ObservableCollection<TableDataRowStringItem> tableobject = new ObservableCollection<TableDataRowStringItem>();
List<TableDataRowStringItem> rowstringList = new List<TableDataRowStringItem>();
TableDataRowStringItem item = new TableDataRowStringItem();
item.RowNumber = 1; item.saveFlag = true; item.ObjectType = "E"; item.Name = "E"; item.PredecessorRowNumber = "0";
rowstringList.Add(item);
item = new TableDataRowStringItem();
item.RowNumber = 2; item.ObjectType = "Function"; item.Name = "Function"; item.PredecessorRowNumber = "1";
rowstringList.Add(item);
item = new TableDataRowStringItem();
item.RowNumber = 3; item.ObjectType = "E"; item.Name = "E"; item.PredecessorRowNumber = "2";
rowstringList.Add(item);
rowstringListEPK = rowstringList;
for (int i = 0; i < rowstringList.Count; i++)
{
tableobject.Add(rowstringList[i]);
}
DataGrid1.ItemsSource = tableobject;
//Button Code
foreach (TableDataRowStringItem item in rowstringListEPK)
{
if (item.ObjectType == "Function" **(&& Hier i schould write if row.Isselected)**)
{
rowStringItem.Name = item.Name;
tabControl.Items.Add(tabItem);
tabItem.Focus();
tabItem.IsSelected = true;
tabItem.Header = rowStringItem.Name;
TableTab.Visibility = Visibility.Visible
}
else do nothing
}
//XAML Code
<DataGrid.RowStyle>
<Style TargetType="DataGridRow">
<Style.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter Property="BorderBrush" Value="Blue" />
<Setter Property="BorderThickness" Value="1" />
<Setter Property="AllowDrop" Value="True" />
</Trigger>
</Style.Triggers>
</Style>
</DataGrid.RowStyle>

这可能有所帮助:
<DataGrid SelectionMode="Single" SelectionUnit="FullRow" ...
或
DataGrid dataGrid = new DataGrid();
dataGrid.SelectionUnit = DataGridSelectionUnit.FullRow;
dataGrid.SelectionMode = DataGridSelectionMode.Single;

你的考试将是:
if (dataGrid1.SelectedItem != null) //test if a row is selected
之后
您可以使用
访问数据行 dataGrid1.SelectedItem
