问题 I want create a Rich Text box with or without web view in xamarin forms. I tried many examples but none of that worked for me.

问题 I'm using WinForms and on my Form I have a RichTextBox. When my form is out of focus but visible and I try to highlight/select text, it does not allow me to until the form or textbox itself has focus. I've tried: txtInput.MouseDown += (s, e) => { txtInput.Focus(); } but to no avail and I can't seem to find anything online about this issue. When testing with another program like Notepad, it does possess the desired behavior. 回答1: MouseDown is too late. This is a workaround for sure, but may be

问题 In my program after clicking on the button - selected ListView entries should be copied to RichTextBox. ListView contains contact information, and the effect I want to accomplish is similar to the one in Oultook (when choosing contacts from contact book). Part of my code that serves this purpose looks like that: private void toButton_Click(object sender, EventArgs e) { int start = 0; for (int i = 0; i < contactsListView.SelectedItems.Count; i++) { if (contactsTextBox.TextLength != 0)

问题 In my System.Windows.Controls.RichTextBox, I would like to find a TextRange of a given word. However, it is not giving me the correct PositionAtOffset after the first found word. The first one is correct, and then for the next found words, the position is not correct. Am I using the correct methods? Loop through listOfWords Word= listOfWords[j].ToString(); startPos = new TextRange(transcriberArea.Document.ContentStart, transcriberArea.Document.ContentEnd).Text.IndexOf(Word.Trim());

问题 I created a contentEditable div to use as a rich textarea. It has resize handlers around it that I'd like to get rid of. Any idea how I'd do this? Edit: This appears to be happening because I am absolutely positioning the div, so Firefox adds an infuriating _moz_resize attribute to the element which I cannot turn off. 回答1: Just as a side note, you can disable Firefox's automatic resize handle feature by sending the (somewhat poorly-documented) enableObjectResizing command to the document:

问题 How do i cut,copy,paste from main menu in a multi textboxes form ? How does the menu knows to apply on the active textbox ? 回答1: Please see this article here on Codeproject that does the job in synchronizing each text box's "standard" edit menu such as Copy, Cut, Paste, Undo, Select All. Of course, the code originally targets the .NET 1.1, but it can be easily recompiled to target the newer frameworks as well. 回答2: In the menu click event you can examine this.ActiveControl to see what control
