WPF通过绑定隐藏DataGridColumn [英] WPF Hide DataGridColumn via a binding

问题描述

由于某种原因，我无法隐藏WPF Toolkit的DataGridColumn.我正在尝试执行以下操作:

For some reason I can't hide WPF Toolkit's DataGridColumn. I am trying to do the following:

<dg:DataGridTemplateColumn Header="Item Description" Visibility="{Binding IsReadOnly}">
<dg:DataGridTemplateColumn.CellTemplate>
    <DataTemplate>
        <TextBox Text="{Binding Path=ItemDescription}" />
    </DataTemplate>
</dg:DataGridTemplateColumn.CellTemplate>

这不起作用，因为它正在寻找ItemSource上的IsReadOnly属性(而不是当前类的属性). 如果将此添加为实现INoifyPropertyChanged的ItemSource类的属性，则它仍不会隐藏该列.有没有解决的办法?我希望在单击按钮更改IsReadOnly属性时隐藏该列.

This doesn't work, since it's looking for a IsReadOnly property on the ItemSource (not a property of the current class). If add this as a property of the ItemSource class that implements INoifyPropertyChanged, it still doesn't hide the column. Is there a way around this? I want the column to hid when a button click changes IsReadOnly property.

假设IsReadOnly返回一个Visibility值，并且是一个依赖项属性

Assume IsReadOnly returns a Visibility value and is a dependency property

我完全被困住了，我将非常感谢您的帮助！非常感谢！

I am completely stuck, I would really appreciate the help! Thanks a lot!

推荐答案

如果要绑定到DataGridColumn的IsReadOnly属性，只需在绑定(和转换器)中添加RelativeSource:

If you want to bind to the DataGridColumn's IsReadOnly property, just add a RelativeSource to the Binding (and a converter):

<BooleanToVisibilityConverter x:Key="boolToVis" />

...

<dg:DataGridTemplateColumn Header="Item Description" Visibility="{Binding IsReadOnly, RelativeSource={RelativeSource Self}, Converter={StaticResource boolToVis}}">
