Help Needed on some requirements

[Sudip]

Hi,

We are currently using SfRichTextBoxAdv control. We need help to achieve the following:

1. Removing the shortcuts for opening, save, save as, etc. other than text editing shortcuts like bold, italic, underline, etc.

2. Showing only three font families rather than showing all while editing text.

3. Adding options like insert table, insert image in the context menu rather than using ribbon control?

Thanks in advance.

Hello,

Thanks for your support. It will really help us.

I have one more query

1. How to set the default line spacing to 0.5?

[Sudip]

Hello,

Thanks for your cooperation. We have multiple instances of this control throughout my application. After implementing your solution we found that duplicate context menu is added in different instances.

Please let us know what technique we should follow to solve this problem.

Hi Sudip, 

  

 

 

Regrading set the default line spacing to 0.5 

 

You can set the default line spacing to the control by changing the document paragraph property. Please refer the below code example. 

 

richTextBox.Document.ParagraphFormat.LineSpacing = 0.9; 

 

But as per the micro soft word standard the minimum value of Linespacing should be greater then equal to 0.9px. So, we couldn’t set this value 0.5, if you force set than it leads to text clipping issue. 

  

  

 

 

Regarding duplicate context menu is added in different instances 

 

We were able to reproduce reported issue. We will validate and get back to you with further details on October 17^th, 2019.

Thanks for your solution.

Your provided code for line spacing is working when the editor does not have predefined text. 

If the editor has some predefined text, in spite of putting your provided line spacing code, the editor is taking more line spacing

Hi Sudip, 

If you want to apply the default line spacing for loaded document and new document, please set the value in both the control Loaded event and Document changed event. Please refer the below code sample. 

 

//Hook the control loaded event 

sfRichTextBox.Loaded += SfRichTextBox_Loaded; 

//Hook the document changed event 

sfRichTextBox.DocumentChanged += SfRichTextBox_DocumentChanged; 

//Occurs when the element is laid out, rendered, and ready for interaction. 

private void SfRichTextBox_Loaded(object sender, RoutedEventArgs e) 

{ 

sfRichTextBox.Document.ParagraphFormat.LineSpacing = 0.9; 

} 

 

//Occurs when the document is changed in this control 

private void SfRichTextBox_DocumentChanged(object obj,DocumentChangedEventArgs args) 

{ 

//Sets the line height as exactly 0.9 pixels within the document default paragraph format. 

sfRichTextBox.Document.ParagraphFormat.LineSpacing = 0.9; 

} 

 

 

Note:  For loaded document, default format is applied only if the Linespacing property of paragraph format is not defined. If it is defined in that loaded document, then control use that value. 

For your information: Linespacing behaviour in RichTextBox 

 

Here the line spacing is work more like line height.  

 

Linespacing type	behaviour
LineSpacingType.AtLeast  (Minimum Line Height)	Specifies that the height of the line shall be at least the  value specified, but might be expanded to fit its  content as needed.
LineSpacingType.Exactly  (Exact Line Height)	Specifies that the height of the line shall be exactly the  value specified, regardless of the size of the contents  of the contents.    If the contents are too large for the specified height,  then they shall be clipped as necessary.
LineSpacingType.Multiple	This will multiple the line height with line spacing value.    For example, consider   Type = Multiple  Line height = 10  Line spacing = 2    Than the actual space added between two line is 10 * 2 = 20.  So, if you want to set small value. set line space like 1 or 0.9
