DataGrid Tooltip - Cell值和ToolTip值一样
<DataGridTextColumn Header="Borrower Name" Binding="{Binding BorrowerName}" IsReadOnly="True" MinWidth="150" Width="150" MaxWidth="1000"><DataGridTextColumn.CellStyle><Style TargetType="DataGridCell"><Setter Property="ToolTip" Value="{Binding BorrowerName}"></Setter></Style></DataGridTextColumn.CellStyle>
</DataGridTextColumn>3. DataGrid Tooltip - Cell值和ToolTip值不一样
<DataGridTextColumn Header="Borrower Name" Binding="{Binding BorrowerName}" IsReadOnly="True" MinWidth="150" Width="150" MaxWidth="1000"><DataGridTextColumn.CellStyle><Style TargetType="DataGridCell"><Setter Property="ToolTip" Value="{Binding BorrowerNameToolTip}"></Setter></Style></DataGridTextColumn.CellStyle>
</DataGridTextColumn>4. DataGrid - Ctrl +A /Ctrl + C复制的内容不是Cell的值
默认copy的内容是Cell的value， 即Binding的field的value。
但是有时候我们想copy的是其他的field值，怎么办？
比如我们这个列显示的是一些内容的缩写，但是拷贝的时候需要拷贝全整的内容。
此时可以通过指定ClipboardContentBinding去解决此类问题。
<DataGridTextColumn Header="Sending To" Binding="{Binding singleRecipient}" IsReadOnly="True" MinWidth="200" Width="240" ClipboardContentBinding="{Binding Recipients}"><DataGridTextColumn.CellStyle><Style TargetType="DataGridCell"><Setter Property="ToolTip" Value="{Binding Recipients}"></Setter></Style></DataGridTextColumn.CellStyle></DataGridTextColumn>5. DataGrid - Edit -Combox
<DataGridTemplateColumn Width="180" IsReadOnly="False"><DataGridTemplateColumn.HeaderTemplate><DataTemplate><StackPanel Orientation="Horizontal"><TextBlock FontWeight="SemiBold" Text="Account Name "/><Image Source="..\..\..\Images\question_mark.png" Height="15" Width="15" HorizontalAlignment="Right" Grid.Column="1" ToolTipService.ToolTip="Bla bla bla..." /></StackPanel></DataTemplate></DataGridTemplateColumn.HeaderTemplate><DataGridTemplateColumn.CellTemplate><DataTemplate><StackPanel Orientation="Horizontal" HorizontalAlignment="Left"><Label ToolTip="{Binding SelectedAccount.Name}" Content="{Binding SelectedAccount.Name}" Visibility="{Binding Path=IsAccountEdit, Converter={StaticResource BooleanToVisibilityConverter}, ConverterParameter=false}"></Label></StackPanel></DataTemplate></DataGridTemplateColumn.CellTemplate><DataGridTemplateColumn.CellEditingTemplate><DataTemplate><ComboBox Visibility="{Binding Path=IsAccountEditShow, Converter={StaticResource BooleanToVisibilityConverter}, ConverterParameter=false}" Width="170" SelectedValue="{Binding SelectedAccount, RelativeSource={RelativeSource AncestorType={x:Type DataGrid}, Mode=FindAncestor}}" x:Name="cbxSelectedAcount" SelectionChanged="cbxSelectedAcount_SelectionChanged"ItemsSource="{Binding Path=Accounts, UpdateSourceTrigger=PropertyChanged}"IsEnabled="{Binding DataContext.NoticeTemplate.Payment.IsTypeBorrowingOIDAndHasAgentAccountId, Converter={StaticResource InverseBooleanConverter}, RelativeSource={RelativeSource AncestorType={x:Type DataGrid}, Mode=FindAncestor}}"><ComboBox.ItemTemplate><DataTemplate><TextBlock Text="{Binding Account.Name}" Foreground="Black"/></DataTemplate></ComboBox.ItemTemplate></ComboBox></DataTemplate></DataGridTemplateColumn.CellEditingTemplate></DataGridTemplateColumn> private void cbxSelectedAcount_SelectionChanged(object sender, SelectionChangedEventArgs e){if (e.AddedItems.Count > 0){var selectedAccount = e.AddedItems[0] as AccountDto;}}6. DataGrid - 解决DataGridTemplateColumn无法排序的问题
DataGrid设置了CanUserSortColumns="True"后，DataGridTemplateColumn点击Header后无法支持排序。此时可通过指定CanUserSort="True" 和SortMemberPath="SelectedAccount.Name"解决。
<DataGridTemplateColumn Width="180" IsReadOnly="False" CanUserSort="True" SortMemberPath="SelectedAccount.Name" ><DataGridTemplateColumn.HeaderTemplate><DataTemplate><StackPanel Orientation="Horizontal"><TextBlock FontWeight="SemiBold" Text="Account Name "/><Image Source="..\..\..\Images\question_mark.png" Height="15" Width="15" HorizontalAlignment="Right" Grid.Column="1" ToolTipService.ToolTip="Wire Instructions of the selected Account will be used on the Notice.

Accounts are setup at the Facility Level under the Lender's Admin Details.

If an Account is unavailable:
1) Check if its Currency matches the Payment Currency
2) Check it's selected for ALL applicable Payment Types" /></StackPanel></DataTemplate></DataGridTemplateColumn.HeaderTemplate><DataGridTemplateColumn.CellTemplate><DataTemplate><StackPanel Orientation="Horizontal" HorizontalAlignment="Left"><Label ToolTip="{Binding SelectedAccount.Name}" Content="{Binding SelectedAccount.Name}" Visibility="{Binding Path=IsAccountEdit, Converter={StaticResource BooleanToVisibilityConverter}, ConverterParameter=false}"></Label></StackPanel></DataTemplate></DataGridTemplateColumn.CellTemplate><DataGridTemplateColumn.CellEditingTemplate><DataTemplate><ComboBox Visibility="{Binding Path=IsAccountEditShow, Converter={StaticResource BooleanToVisibilityConverter}, ConverterParameter=false}" Width="170" SelectedValue="{Binding SelectedAccount, RelativeSource={RelativeSource AncestorType={x:Type DataGrid}, Mode=FindAncestor}}" x:Name="cbxSelectedAcountForLender" SelectionChanged="cbxSelectedAcountForLender_SelectionChanged"ItemsSource="{Binding Path=Accounts, UpdateSourceTrigger=PropertyChanged}"><ComboBox.ItemTemplate><DataTemplate><TextBlock Text="{Binding Account.Name}" Width="150" Foreground="Black"/></DataTemplate></ComboBox.ItemTemplate></ComboBox></DataTemplate></DataGridTemplateColumn.CellEditingTemplate></DataGridTemplateColumn>
