Question

datagrid 控件，如何点击一次某单元格，即可获取该单元格的内容？

目前，只能点两次才能获取，
或者点击下一个单元格，才能获取上一个单元格的内容，求助

Answer 1

前台代码：
<Grid >
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition Height="25"/>
</Grid.RowDefinitions>
<DataGrid Name="dg" AutoGenerateColumns="True" RowHeaderWidth="0" SelectedCellsChanged="dg_SelectedCellsChanged" SelectionUnit="Cell"></DataGrid>
<TextBlock Grid.Row="1" Name="txt"/>
</Grid>
后台代码：
public partial class BaiduKnows : Window
{
public BaiduKnows()
{
InitializeComponent();
List<People> peoplelist = new List<People>();
peoplelist.Add(new People() { age = 10, name = "linda" });
peoplelist.Add(new People() { age = 11, name = "tom" });
peoplelist.Add(new People() { age = 12, name = "peter" });
peoplelist.Add(new People() { age = 13, name = "mary" });
dg.ItemsSource = peoplelist;
}
class People
{
public int age { get; set; }
public string name { get; set; }
}
private void dg_SelectedCellsChanged(object sender, SelectedCellsChangedEventArgs e)
{
DataGrid dg = sender as DataGrid;
People item = dg.SelectedCells[0].Item as People;
string colhead = dg.SelectedCells[0].Column.Header.ToString();
switch (colhead)
{
case "age" : txt.Text = item.age.ToString();
break;
case "name": txt.Text = item.name.ToString();
break;
}
}
}

双击了之后不久已经选中了该行了么，然后用这个 dataGridView1.SelectedRows[0].Index 或者用单元格的话 dataGridView1.CurrentCell.RowIndex 那修改下选中方式么，有选中单元格就会选中行的
