Registering of Click event of a button contained in the datatemplate of datagrid which is contained in Silverlight TemplateControl can be triky.
For this reason I pasted here a peace of XAML which contains that grid and corresponding code which subscribes Click-events.
| <data:DataGridTemplateColumn Header="" x:Name="m_BtnColumn"> <data:DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<Button x:Name="m_Button" Tag="{Binding .}" >
</Button>
</DataTemplate>
</data:DataGridTemplateColumn.CellTemplate> |
To make all this working in ApplyTemplate of you remplate controll following has to be done
| m_DataGrid = GetTemplateChild("m_DataGrid") as DataGrid;
if (m_DataGrid == null)
throw new Exception("");
m_DataGrid.LoadingRow += new EventHandler<DataGridRowEventArgs>(grid_LoadingRow); |
Then implement the code which subscribes events:
| void grid_LoadingRow(object sender, DataGridRowEventArgs e)
{
var btnCol =
m_DataGrid.Columns.FirstOrDefault( c => c.GetValue(FrameworkElement.NameProperty) as string == "m_BtnColumn");
FrameworkElement el = btnCol.GetCellContent(e.Row);
Button btn = el as Button;
if (btn != null)
{
btn.Click -= new RoutedEventHandler(btn_Click);
btn.Click += new RoutedEventHandler(btn_Click);
}
}
void btn_Click(object sender, RoutedEventArgs e)
{
} |
