Changing Default Font and Size

I got it figured out.

Troy,

Your solution is correct. If the document already has content you should select it first.

Please let me know if there is something else I can help you with.

If you are working on windows 7 or higher, the root drive ("C:\") is not a great place to access files from as the security is set real high.

 

I suggest using "C:\Temp\123.docx" and make sure you can read and write to that folder

see i am custom the code put when run see attache

-----------------code

  public RadDocument ImportFile()
        {

            RadDocument document = null;

            IDocumentFormatProvider provider = new TxtFormatProvider();
            //
            System.Windows.Forms.OpenFileDialog openDialog = new System.Windows.Forms.OpenFileDialog();
            openDialog.Filter = "Documents|*.docx";
            openDialog.Multiselect = false;
            DialogResult dialogResult = openDialog.ShowDialog();
            //
            if (dialogResult == System.Windows.Forms.DialogResult.OK)
            {
                using (Stream stream = openDialog.OpenFile())
                {
                    document = provider.Import(stream);
                }
            }
                //using (System.IO.Stream stream = System.IO.File.Open("c:\\123.docx", System.IO.FileMode.Open))
                //{

                //    document = provider.Import(stream);

                //}

                RadDocumentEditor editor = new RadDocumentEditor(document);

                document.Selection.SelectAll();

                editor.ChangeFontSize(10);

                editor.ChangeFontFamily(new Telerik.WinControls.RichTextEditor.UI.FontFamily("Consolas"));

                Telerik.WinForms.Documents.Layout.Padding marg = new Telerik.WinForms.Documents.Layout.Padding(15, 15, 15, 15);

                editor.ChangeSectionActualPageMargin(marg);

                editor.ChangeParagraphSpacingAfter(0.0);

                editor.ChangeParagraphSpacingBefore(0.0);



                radRichTextEditor1.CurrentEditingStyle.SetPropertyValue(Span.ForeColorProperty, Colors.Red);

Hello guys,

Thank you for writing.

@Mahmoud
I am sending you attached a sample project in which I am importing a .docx file into RadRichTextEditor. Basically, I have followed the example as demonstrated here: Import/Export. You should also make sure that the file you are trying to read is available, not locked and you have the required permissions to access it. In my project, I have also demonstrated how the content can be cleared and how the spacing can be decreased. For detailed information and examples of the available features in RadRichTextEditor please refer to the following section of our documentation: Features.

Considering your request, regarding the Al- font, please check the following forum thread as the same matter has also been discussed there: http://www.telerik.com/forums/changing-copied-arabic-text-font-in-document-richtexteditor.

My example is in C#, in case you need conversion between VB and C# and vice versa, please note that we have a free online tool available here: http://converter.telerik.com/.

I hope this helps. Should you have further questions please do not hesitate to write back.

After I had call the function which you give on Form Loading event handler, I input text. But font is not changed.

Should I call the function whenever inputting text?

I hope that I set font at first time, and it kept by I change to another font.

 

Hello ,

Thank you for writing back.

If you would like to change the font styling of the document, you need to make sure that the document you are importing is actually loaded. For the purpose, you can subscribe to the DocumentChanged event.

In case you are working with an empty document and you call the method I last sent you in the Load event of the form, this should apply the settings and the new text you enter should be with the newly applied style.

I am sending you attached my sample project as well as a gif file showing the result on my end. If you are still experiencing issues please send me a code snippet demonstrating your local setup.

I hope this helps. Should you have further questions please do not hesitate to write back.

Dear Admin,
I've used Radrichtexteditor in my project. In addition, I've used richtexteditorribbonbar and it is associated to radrichtexteditor.
In my project I get information from user through radRichTextEditor1 and convert context to Html for save in database (of course for this reason i used ImportHTML and exporttoHTML function ), my problem is : during execution , sometimes I face in this error ;
"{The function evaluation was disabled because of an out of memory exception.}"

I checked it and I figure out after each 10 times that user open the form contains of radrichtexteditor+richtexteditorribbonbar , this error is appeared.
How can I solve this problem?
I've attached the pic of error too, thanks a million for guiding me.

I have another problem too about opening the form which contain radrichtexteditor+richtexteditorribbonbar  , it takes to much time to open and it is no acceptable for user, what can I do to improve the time ?

Hi Rosa,

If this form has many controls it, creating a new instance can be delayed a little bit. In this case, you can create a single instance and then just show/hide the form when it is needed. This will reduce the memory footprint as well. 

In addition, I have noticed that you have opened a new thread for this and we can continue to discuss this matter there. In general, there can be many reasons for the memory leak (a reference to another object, subscription to an event). The following article shows what you need to check in order to resolve this: Things to keep in mind when inspecting your application's memory usage.

I hope this information is useful.

Hello,

This topic is driving me mad!! I have been trying to get a default font and size for the RadTextBoxEditor for 3 days. I tried each and every piece of code that is described below but until now not with the desired result.

I know this is already an old topic, and it seems to be solved since the last post was of 2015, but I don't get the control to behave as I want.

I need the RichTextBoxEditor because of the MailMerge possibilities, but I don't want the user to change font size, type, colors or nothing, as the output will be a text file.

Due to company rules, I need a default font and size in the application.

To be short: I want the control to behave as a normal textbox, except for the mailmerge fields.

Scenario 1:
Set the default font family and size.
I load a document from Xaml with the XamlFormatProvider, OK.
I select the entire document, change the font family and font size. OK.
Now the user starts to type after the loaded text: to my horror font size 12 and original family again....

Scenario 2:
I don't load any document. Set the default font family and size.
The user starts to type, OK.
The user reconsiders, types Ctrl-A, Delete, starts typing again -> back to font size 12 and original family again...

I'm using version 2017 Q1...

What am I overlooking?

Hi Harm,

In order the font to remain when the entire content is deleted, you need to change the "Normal" style. This should be done for each imported or new document as well:

I hope this will be useful.

Finally the solution I was looking for.

Thanks a million!
