问题
I'm just learning WPF, and I gragged a table from a datasource onto a window which generated XAML for each column.
Some of those columns had names that caused the following:
<DataGridTextColumn x:Name="_Rev_UnitColumn" Binding="{Binding Path=Rev/Unit}" Header="Rev/Unit" Width="SizeToHeader" />
This causes the column to come up blank (like me).
回答1:
I (kind of randomly) tried:
<DataGridTextColumn x:Name="_Rev_UnitColumn" Binding="{Binding Path=[Rev/Unit]}" Header="Rev/Unit" Width="SizeToHeader" />
And the result was everything worked as I expected it to. Looking at it again, I guess H.B.'s MSDN quote tells me this. When I read that (originally on MSDN before I even posted this question, then again here) I just didn't understand what "Inside indexers --comma-- the caret character (^) escapes the next character" meant.
回答2:
On MSDN there is an article on property paths which has a section on escape characters:
Inside indexers ([ ]), the caret character (^) escapes the next character.
You must escape (using XML entities) certain characters that are special to the XML language definition. Use & to escape the character "&". Use > to escape the end tag ">".
You must escape (using backslash \) characters that are special to the WPF XAML parser behavior for processing a markup extension.
- Backslash (\) is the escape character itself.
- The equal sign (=) separates property name from property value.
- Comma (,) separates properties.
- The right curly brace (}) is the end of a markup extension.
The slash is not listed here so i do not know if the backslash escape would work, but you can try.
(How exactly do you have a property name like that? It seems to be illegal both in XML and C#)
