C1DATAGRID中DataTemplate的显示问题

登录

SILVERLIGHT5.0
C1DATAGRID中DataTemplate显示操作按钮必须点击一行前面的按钮（如图1）才可以实现图2的效果，我希望实现点击一行记录时，直接显示为图2的效果，请问有没有办法？

sygmonitor 你好，

感谢你的问题反馈。

通过 DataTemplate 定制的模板是可以直接在单元格中显示的。
请问你是如何设置的？能否把你实现第二张图的代码共享出来，这样有助于加快问题解决进度。

sygmonitor 你好，

问题我已经清楚了，正在调查中，请稍候。

sygmonitor 你好，
不好意思，让你久等了。
C1DataGrid 的 RowDetailsTemplate 可见性通过 DetailsVisibility 属性控制，可以通过 CurrentCellChanged 事件来响应点击事件，在事件中设置 DetailsVisibility 属性：

void mygrid_CurrentCellChanged(object sender, C1.Silverlight.DataGrid.DataGridCellEventArgs e)
{
e.Cell.Row.DetailsVisibility = System.Windows.Visibility.Visible;
}

这样导致的结果是被点击过的都显示下拉模板了，我想达到只显示一行的效果！
我已通过自己的方法实现此效果，代码：

void grid_SelectionChanged(object sender, DataGridSelectionChangedEventArgs e)
{
try
{
C1DataGrid c1 = sender as C1DataGrid;
foreach (var item in c1.Rows)
{
item.DetailsVisibility = Visibility.Collapsed;
}
C1.Silverlight.DataGrid.DataGridCell cell = c1.CurrentCell;
cell.Row.DetailsVisibility = Visibility.Visible;
}
catch { }
}

是的，也是一种实现方法，我是通过以下方法实现的：

C1.Silverlight.DataGrid.DataGridCell cell;
void mygrid_CurrentCellChanged(object sender, C1.Silverlight.DataGrid.DataGridCellEventArgs e)
{
if (!cell.Equals(e.Cell))
{
cell.Row.DetailsVisibility = System.Windows.Visibility.Collapsed;
e.Cell.Row.DetailsVisibility = System.Windows.Visibility.Visible;
cell = e.Cell;
}
}

你的方法我无法实现，报错误

sygmonitor 你好，

报错的原因是 Cell 没有初始化，cell = this.mygrid.GetCell(0, 0);

public MainPage()
{
InitializeComponent();
List<Student> stus = new List<Student>();
for (int i = 0; i < 50; i++)
{
Student st = new Student();
st.Name = "test";
st.Score = 12;
stus.Add(st);
}
this.mygrid.AutoGenerateColumns = false;
this.mygrid.ItemsSource = stus;
this.mygrid.CurrentCellChanged += new EventHandler<C1.Silverlight.DataGrid.DataGridCellEventArgs>(mygrid_CurrentCellChanged);
cell = this.mygrid.GetCell(0, 0);
}
C1.Silverlight.DataGrid.DataGridCell cell;
void mygrid_CurrentCellChanged(object sender, C1.Silverlight.DataGrid.DataGridCellEventArgs e)
{
if (!cell.Equals(e.Cell))
{
cell.Row.DetailsVisibility = System.Windows.Visibility.Collapsed;
e.Cell.Row.DetailsVisibility = System.Windows.Visibility.Visible;
cell = e.Cell;
}
}
}
public class Student
{
public String Name { get; set; }
public int Score{get;set;}
}
