Make sure the text property includes a valid url. E.g. http://www.stackoverflow.com/ set the DetectUrls property to true Write an event handler for the LinkClicked event. Personally, I wouldn’t pass “IExplore.exe” in as a parameter to the Process.Start call as Microsoft advise as this presupposes that it is installed, and is the user’s preferred browser. If … Read more
This is a RichTextBox that I have used in the past. It’s spliced together from code found here at Stack Overflow and the internet at large: public class RichBox : RichTextBox { private const UInt32 CFM_BOLD = 0x00000001; private const UInt32 CFM_ITALIC = 0x00000002; private const UInt32 CFM_UNDERLINE = 0x00000004; private const UInt32 CFM_STRIKE = … Read more
Thanks Jay for your answer; after some more searching I also found the method described here. I’ll outline it below for anyone else interested. First, declare the following enums: public enum ScrollBarType : uint { SbHorz = 0, SbVert = 1, SbCtl = 2, SbBoth = 3 } public enum Message : uint { WM_VSCROLL … Read more
Yes you can set the BackColor of a RichTextBox Selection using the RichTextBox.SelectionBackColor Property. int blockStart = 1; //arbitrary numbers to test int blockLength = 15; richTextBox1.SelectionStart = blockStart; richTextBox1.SelectionLength = blockLength; richTextBox1.SelectionBackColor = Color.Yellow;
This should get you close to what you are looking for. This class inherits from the RichTextBox and uses some pinvoking to determine the scroll position. It adds an event ScrolledToBottom which gets fired if the user scrolls using the scrollbar or uses the keyboard. public class RTFScrolledBottom : RichTextBox { public event EventHandler ScrolledToBottom; … Read more
I did it with style (pun indented) <RichTextBox Margin=”0,51,0,0″ Name=”mainTextBox” > <RichTextBox.Resources> <Style TargetType=”{x:Type Paragraph}”> <Setter Property=”Margin” Value=”0″/> </Style> </RichTextBox.Resources> </RichTextBox>
Try this: static void HighlightPhrase(RichTextBox box, string phrase, Color color) { int pos = box.SelectionStart; string s = box.Text; for (int ix = 0; ; ) { int jx = s.IndexOf(phrase, ix, StringComparison.CurrentCultureIgnoreCase); if (jx < 0) break; box.SelectionStart = jx; box.SelectionLength = phrase.Length; box.SelectionColor = color; ix = jx + 1; } box.SelectionStart = … Read more
I found a solution. Set IsDocumentEnabled to “True” and set IsReadOnly to “True”. <RichTextBox IsReadOnly=”True” IsDocumentEnabled=”True” /> Once I did this, the mouse would turn into a ‘hand’ when I hover over a text displayed within a HyperLink tag. Clicking without holding control will fire the ‘Click’ event. I am using WPF from .NET 4. … Read more
System.Windows.Forms.RichTextBox has got a property of type Color of the name SelectionColor which gets or sets the text color of the current selection or insertion point. You can use this property to mark specific fields in your RichTextBox with the colors you specify. Example RichTextBox _RichTextBox = new RichTextBox(); //Initialize a new RichTextBox of name … Read more
It’s a little bit tricky to detect a paste operation in the RichTextBox. First solution may be to detect the WM_PASTE message overriding the WndProc but unfortunately the control doesn’t send that message to itself when it performs a paste operation. Naïve detection To detect the keyboard events may work (you have to override the … Read more
