richtextbox

问题 We have a Silverlight application using the RichTextBox as a rich text editor for the user to create emails. We actually have our own serializer but essentially we are saving and restoring the Xaml. As far as I can tell it is impossible to restore any text containing curly braces. You can demonstrate this fairly easily by creating a RichTextBox and typing something similar to {weird} into it. Then take the .Xaml property of the textbox and set it on the .Xaml property of another textbox -

问题 I have a custom RichTextBox Control derived from RichTextBox Control that Windows provides. I am unable to capture the dragDrop Event though the DragEnter event is getting captured, but I dont know why the dragDrop event is not. I have following properties set as true: EnableAutoDragDrop=true; AllowDrop=true; What am I missing ?? 回答1: Daniel is probably correct here: private void DragOver(object sender, System.Windows.Forms.DragEventArgs e) { if (!e.Data.GetDataPresent(typeof(System.String)))

问题 Sometimes a user will type a website URL while chatting in a Chat Application. I need to make the RichTextBox detect these URLs automatically, but I do not know how. General TextBox does not detect URLs, so i have used RichTextBox instead. I know RichTextBoxes can detect URLs but I don't know how. Can anybody suggest how I might do this? 回答1: As schoola pointed out, the WPF RichTextBox does not auto-detect URLs. However this article describes a fairly simple (150 line) implementation of a

问题 We have a Canvas contained in a ScrollViewer. Users can add an unlimited number of UserControls that, to oversimplify, are a RichTextControl surrounded by a number of decorative rectangles. We have an arranger that positions all the UserControls so none overlap. When the arranger runs, it calculates a new position for each UserControl and sets its X and Y on the Canvas. Something is causing the ScrollViewer to scroll, however, so that after the arranger runs the user might have a different

问题 Is there some way I can detect or cause an event to fire whenever text is pasted into a RichTextBox? Or maybe there is already some kind of event that fires when text is pasted? This is Winforms C#, by the way. 回答1: Because not all people may use Ctrl+V and because there are other ways to get text into a text box (such as drag and drop), I went a different route, which I will share here in case anyone else is looking for a solution. What I did was create a field in my class: int _lastPosition

问题 When I select or double-click on a word in the RichTextBox , a panel should appear above this word (This panel is initially hidden and appears when the word is highlighted). When I remove the selection, the panel should disappear. private void richTextBox1_SelectionChanged(object sender, EventArgs e) { if (richTextBox1.SelectedText.Length > 0) panel1.Visible = true; else panel1.Visible = false; } 回答1: According to your changes, you need a custom control to achieve this. Set your custom

问题 I have the following code which works fine in notepad but not in WORD!!

问题 I have a RichTextBox that I want to re-format when the contents of the RichTextBox changes. I have a TextChanged event handler. The re-formatting (changing colors of selected regions) triggers the TextChanged event. It results in a never-ending loop of TextChange event, reformat, TextChange event, reformat, and so on. How can I distinguish between text changes that result from the app, and text changes that come from the user? I could check the text length, but not sure that is quite right.

问题 I'm working on a windows form application and I want to have a rich text box display the status of events that are firing based on different objects. I want to be able to format the items as they come into the rtb using the rtf property so that they can be easily distinguished from each other by changing font weight and color. The format would contain <b><datetime></b> - <colored text>Event Type</colored text> - <plain text>Event Details</plain text> I've been doing a lot of research on RTF
