If I copy some text with different format and paste it to my richtextbox it is not plain I mean its format will be copied as well.
Is there anyway I can copy-paste as a plain text?
By the way my program is on WinForm
thanks for any answer
you must use WinForm RichTextBox (not in UI, just in code), even if you are on WPF, in order to convert RTF to plain text. Use this method in your Copy event.
C# code :
private String ConvertRtfToText()
{
System.Windows.Forms.RichTextBox rtfBox = new System.Windows.Forms.RichTextBox();
rtfBox.Rtf = this.rtfData;
return rtfBox.Text;
}
VB.Net Code :
Private Function ConvertRtfToText() As String
Dim rtfBox As RichTextBox = New RichTextBox()
rtfBox.Rtf = Me.rtfData
Return rtfBox.Text
End Function

I recently had the same issue. I did want to retain some of the formatting, i.e. paragraphs and line feeds, but I required all the addition text format to be removed.
I'm working in WPF but the RichTextBox interface is the same. I have created a button that will allow users to select some text and remove the formatting. It is very simple, you just need to use the ClearAllProperties() method on the TextSelection object.
C# Code (WPF):
private void ClearFormat_Click(object sender, RoutedEventArgs e)
{
rtbText.Selection.ClearAllProperties();
}
This is a super easy solution but perhaps not super elegant...
1) Add a plain textbox to your form and make it hidden
2) Create a button to remove the formatting (or you can do this
automatically when the text is pasted)
3) In the OnClick (or OnPaste) code just copy the text from the rich
textbox control to the plain textbox control then copy the text
from the plain textbox back to the rich textbox control (see example
below)
private void btnRemoveFormatting_Click(object sender, EventArgs e)
{
txtPlainText.Text = txtRTF.Text;
txtRTF.Text = ""; // Required - this makes sure all formatting is gone
txtRTF.Text = txtPlainText.Text;
}

I have a RichTextBox onto which I write long lists of data using a simple write method (see down)
I use vertical scrolbar, and writing and clearing is fine.
The problem is with new text after clearing the text.
I use textbox.clear(); which clears the box OK, but when new text arrives, the old (cleared!) text shows up again, followed by the new text.
I have also tried:
ResetText, Refresh, Update. dispose, Text =" , richTextBox.Document.Blocks.Clear(); (dont have that one).
Have also tried new textbox = new textbox, all for no avail.
The text shows again and again, until I reset the application.
I have seen several form threads on that one, but non helped.
My guess: I use both scroll bars. A scrollbar must have a buffer, The data is kept somewhere in the active scrollbar buffer?
Any (good) idea will be blessed.
This is how I write / erase the text in the richtextbox:
(simplified. mainDisplay is a RichTextBox)
public void mainDisplayText(string text)
{
this.mainDisplay.AppendText(text);
this.mainDisplay.ScrollToCaret();
}
private void btnClear_Click(object sender, EventArgs e)
{
//Have tried all these options:
this.mainDisplay.Text = ""; //or
this.mainDisplay.Clear(); //or
this.mainDisplay.SelectAll(); //or
this.mainDisplay.SelectedText = "";
}
You're reusing the same string, so:
this.mainDisplay.Clear();
text = string.Empty;
Should do the trick :)
Strange indeed. Could this be some issue in .net 4.7.x ? Since last week I compile everything in 4.7.2 and this problem has surfaced here also. Clear() seems to bring back the .Text content. So a Clear() after Text="" does not work.
I am trying to create a WPF application that has a richtextbox which accepts dictations from the user as its input.
I want to use this code for the SpeechRecognized event for an an object of the SpeechRecognitionEngine class.
private void speechRecognizer_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
{
e.Result.Text = rtb.Text; //rtb is an object of the RichTextBox class
}
The problem is that there is no Text property for the RichTextBox class. Is there any way of fixing this? Thanks in advance
Try this:
private void speechRecognizer_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
{
rtb.AppendText(e.Result.Text);
}
This is a well documented problem and there are many different solutions for it. You can find a large number of possible solutions in the answers to the RichTextBox (WPF) does not have string property “Text” question here on Stack Overflow.
However, my preferred method would be to declare a Text Attached Property for the RichTextBox class. Please see the Attached Properties Overview page on MSDN to find out more about Attached Properties. You can find out what code to use in your Text Attached Property for the RichTextBox class in the RichTextBox Text property where are you hiding? tutorial on C# Disciples website.
RichTextBox contents can be set via Document property. You can find more details on MSDN
Here is an example from the link provided above. It creates a new document and a paragraph for it, then assigns the document to RichTextBox:
// Create a simple FlowDocument to serve as content.
FlowDocument flowDoc = new FlowDocument(new Paragraph(new Run("Simple FlowDocument")));
// Create an empty, default RichTextBox.
RichTextBox rtb = new RichTextBox();
// This call sets the contents of the RichTextBox to the specified FlowDocument.
rtb.Document = flowDoc;
// This call gets a FlowDocument representing the contents of the RichTextBox.
FlowDocument rtbContents = rtb.Document;
I have a RichTextBox control in my view. I'm using code-behind (UI logic only) to format the RTF within my RichTextBox which is working from a 'Format' button click event which instantiates a TextRange:
private void _btnFormat_Click(object sender, RoutedEventArgs e)
{
TextRange rangeOfText = new TextRange(richTextBoxArticleBody.Document.ContentStart, richTextBoxArticleBody.Document.ContentEnd);
rangeOfText.ApplyPropertyValue(TextElement.ForegroundProperty, Brushes.Black);
rangeOfText.ApplyPropertyValue(TextElement.FontSizeProperty, "12");
rangeOfText.ApplyPropertyValue(TextElement.FontFamilyProperty, "Arial");
rangeOfText.ApplyPropertyValue(TextElement.FontStyleProperty, "Normal");
rangeOfText.ApplyPropertyValue(Inline.TextDecorationsProperty, null);
}
I want to also remove any tables within the RTF. Can I use the same approach maybe from the Table class to remove tables from my RichTextBox? Thanks
You'll have to climb down the Blocks and get the descendants
of the FlowDocument and get all the Tables and then remove them from the its Parent.
Ok, if anyone is trying to achieve this I don't think it's possible. Maybe you can iterate over a simple table in an Rtf string and remove the tags but if you can't determine user input the Rtf is by far too complex. Therefore here's my solution (of sorts...)
private void _btnFormat_Click(object sender, RoutedEventArgs e)
{
TextRange rangeOfText = new TextRange(richTextBoxArticleBody.Document.ContentStart, richTextBoxArticleBody.Document.ContentEnd);
rangeOfText.ApplyPropertyValue(Table.BorderThicknessProperty, "3");
rangeOfText.ApplyPropertyValue(Table.BorderBrushProperty, Brushes.Red);
}
In the 'Format' button click event I've set table borders to Red. On my save back to the database method I've used this simple if statement:
private void SaveToDbCommandAction()
{
if(PastedText.Contains("trowd"))
{
Xceed.Wpf.Toolkit.MessageBox.Show("Cannot save Article. Please remove pasted tables");
}
else
{
SaveToDb(RTBText);
}
}
Therefore when the user pastes in a table they are warned via the red cell borders. This is particularly useful if they paste a table with invisible borders and can't actually see the table. The If statement then determines whether the Rtf string contains a 'trowd' tag therefore preventing the save.
I'm using a 'Paste' button command in my view Model to copy RTF from the clipboard. PastedText is my string property that a RichTextBox is bound to in my view:
private void FormatPastedTextCommandAction()
{
PastedText += Clipboard.GetText(TextDataFormat.Rtf);
}
This works and the text is pasted on pressing the Paste button. However, I want to lock down the formatting on the paste function and remove all formatting from the pasted RTF string (colour, italics, set to black Arial 12).
I would just use PastedText += Clipboard.GetText();
to get the plain text but it pastes in at a different font size and I need it in RTF format. I've looked at iterating over the RTF string and doing a find/replace on font size, colour etc. but the RTF is very complex even for a couple of words.
Is there any way around this? Thanks
In the end I used code behind in the view to strip formatting from the RichTextBox itself using a 'Format' button:
private void _btnFormat_Click(object sender, RoutedEventArgs e)
{
TextRange rangeOfText = new TextRange(richTextBoxArticleBody.Document.ContentStart, richTextBoxArticleBody.Document.ContentEnd);
rangeOfText.ApplyPropertyValue(TextElement.ForegroundProperty, Brushes.Black);
rangeOfText.ApplyPropertyValue(TextElement.FontSizeProperty, "12");
rangeOfText.ApplyPropertyValue(TextElement.FontFamilyProperty, "Arial");
rangeOfText.ApplyPropertyValue(TextElement.FontStyleProperty, "Normal");
rangeOfText.ApplyPropertyValue(Inline.TextDecorationsProperty, null);
rangeOfText.ApplyPropertyValue(Paragraph.MarginProperty, new Thickness(0));
}
This does a good job and doesn't really break the MVVM pattern as the code is UI logic only.
I am trying to copy data from an excel sheet into a a rich text box in a Winform .NET project.
Right now there are grid lines are coming up in the rich text box. How do I eliminate the grid lines from the rich text box.
Because I do not want to show the grid lines in the rich text box.
Please help me
Thanks Sandeep
you can do like this in the keydown event of you richtextbox (if you are using the normal paste method)
private void richTextBox1_KeyDown(object sender, KeyEventArgs e)
{
if (e.Control == true && e.KeyCode == Keys.V)
{
e.Handled = true;
string st = Clipboard.GetText();
richTextBox1.Text = st;
}
}
hope this helps
Banged my head against wall with this one. I was testing the different methods available on the Clipboard class with nUnit and every method returned null. With nUnit, you must add the [RequiresSTA] attribute to the class.
Final result would look like [TestFixture, RequiresSTA].
