'我想将RichTextBox的Height属性绑定到GridView的Row的Height属性。我怎样才能做到这一点?我不知道如何获得Row的高度,因为我无法访问xaml中的Row。我想做什么。
Ancestor类型应该是GridViewHeaderRow,但我不知道它的级别...
修改
<my:RadGridView Height="524" RowHeight="300" ItemsSource="{Binding Lessons}" AutoGenerateColumns="False" Name="dataGrid1" VerticalAlignment="Top" SelectionMode="Single" CanUserSortColumns="False" IsFilteringAllowed="False">
<my:RadGridView.Columns>
<my:GridViewDataColumn DataMemberBinding="{Binding SchoolclassName}" Header="Schoolclass" Width="0.1*" />
<my:GridViewDataColumn DataMemberBinding="{Binding SubjectName}" Header="Subject" Width="0.1*" />
<my:GridViewDataColumn Width="0.3*" Header="Homework">
<my:GridViewDataColumn.CellTemplate>
<DataTemplate>
<RichTextBox Height="{Binding ElementName=dataGrid1,Path=RowHeight}" >
<FlowDocument>

<Run Text="{Binding Homework}"/>

我不知道你的RadGridView。但我要尝试的第一件事就是使用RelativeSource绑定FindAncestor来走向可视树,直到找到GridViewHeaderRow并绑定到它的Height属性。
... Height="{Binding Height, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type GridViewHeaderRow }}}" ...
您可能需要走到树上才能找到RadGridView,然后再向下走到标题行。
... Height="{Binding HeaderRow.Height, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type RadGridView }}}" ...
或
... Height="{Binding Rows[0].Height, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type RadGridView }}}" ...
取决于RadGridView的实现。
