Add custom tooltip to row in DataGrid
提问by Drahcir
I would like to customize my DataGrid to show a tooltip within the selected row, please see the mockup images below for a better idea of what I want to achieve.
我想自定义我的 DataGrid 以在所选行中显示工具提示,请查看下面的模型图片以更好地了解我想要实现的目标。
As it is at the moment- Shows a single selected row:

目前- 显示单个选定行:

How I would like- Shows the same row selected, now with tooltip:
我想要的- 显示选择的同一行,现在带有工具提示:


- My DataGrid uses Binding to the ViewModel.
- Working with WPF & C# for Windows desktop.
- 我的 DataGrid 使用绑定到 ViewModel。
- 在 Windows 桌面上使用 WPF 和 C#。
I don't really have any idea how to achieve this, so I'm open to any suggestions at all.
我真的不知道如何实现这一目标,所以我对任何建议都持开放态度。

I use the DataGrid.RowStyleto set the tooltip.
我使用DataGrid.RowStyle来设置工具提示。
My bound objects have a ToolTipTextproperty which contains the content of the ToolTip.
我的绑定对象有一个ToolTipText属性,其中包含ToolTip.
<DataGrid.RowStyle>
<Style TargetType="DataGridRow">
<Setter Property="ToolTip">
<Setter.Value>
<TextBlock Text="{Binding ToolTipText}" />
</Setter.Value>
</Setter>
</Style>
</DataGrid.RowStyle>

You can use RowDetailsTemplate.
您可以使用RowDetailsTemplate。
Here is sample code:
这是示例代码:
<DataGrid Name="grid" AutoGenerateColumns="False">
<DataGrid.RowDetailsTemplate>
<DataTemplate>
<TextBlock Background="Orange" Text="{Binding MoreInfo}" TextWrapping="Wrap"
HorizontalAlignment="Stretch" VerticalAlignment="Stretch" />
</DataTemplate>
</DataGrid.RowDetailsTemplate>
<DataGrid.Columns>
<DataGridTextColumn Header="ID" Binding="{Binding ID}" />
<DataGridTextColumn Header="ID" Binding="{Binding Name}" />
<DataGridTextColumn Header="ID" Binding="{Binding Surname}" />
</DataGrid.Columns>
</DataGrid>

Another simple way to add a tooltip on a row in a datagrid is the following.
在数据网格中的行上添加工具提示的另一种简单方法如下。
Use the LodingRowEvent and add your tooltip like this:
使用LodingRow事件并添加您的工具提示,如下所示:
private void grdItemlogs_LoadingRow(object sender, DataGridRowEventArgs e)
{
if (e.Row != null)
{
string toolTipText = "Your Tooltip string content"
e.Row.ToolTip = toolTipText;
}
}
