Highlight Search TextBlock

阅读更多关于 Highlight Search TextBlock

问题 My goal is to create a custom TextBlock control that has a new dependency property, SearchText. This property will contain a regular expression. All occurrences of this regular expression in the text of the TextBlock will be highlighted using a custom style (another DP). My current implementation involves clearing all of the Inline objects in the TextBlock's InlineCollection. I then fill the TextBlock with runs for unhighlighted text and runs for highlighted text with the style applied (this

问题 Let us say that I have an empty Textblock : textblock1.Text = ""; Then I only put Inlines content in it with these two statements: textblock1.Inlines.Add(new Run() { Text = "A. ", Foreground = Brushes.Red }); textblock1.Inlines.Add(new Run() { Text = responses.Current.Value, Foreground = Brushes.Black}); The amazing stuff is that I can visualize the content properly in my window, however the Text property of the Textblock keeps being empty! This causes a problem because I need to pass the

问题 I need to override save method of inlines in admin. While saving photos, I need to add user id to DB column. I cant make it in model because there is no request data there.

问题 I use this example ( https://siderite.dev/blog/how-to-draw-outlined-text-in-wpf-and.html ) for add outline to a text in a TextBlock. However this example don't support Inlines. I try to add this ability modifying the OnRender and I iterate the Inlines collection to build a Geometry for each Inline block. The problem is that I need to get the position and size of the inline block in the TextBlock instead of those of the whole text in the TextBlock. This is the source code that I have modified.

问题 I need separate views for add and change page. In add page I'd like to exclude some fields from inline formset. I've prepared two TabularInline classes, one of them contains property 'exclude'.

问题 I have a model that I want staff to be able to edit up to the date for the event. Like this: class ThingAdmin(admin.ModelAdmin): model = Thing if obj.date < today: #Something like that inlines = [MyInline,] The problem is, I don't have access to the obj instance at this level. I've tried overriding get_formset(), but didn't get anywhere. Please advise? 回答1: Thanks to the comments for a change in 1.4. My implementation here wasn't thread safe either, so it really should have been deleted.
