Hi,

We have a WPF solution with a blog, the blog messages are being saved into our database as RadDocuments.

Now we are building a MVC-solution which should also be able to show this blog.

 

 

The Problems are:

    1. how do I convert the RadDocument to HTML?

    2. how do I convert the RadDocument to RadFlowDocument so I can work with it in the Kendo.Editor?

 

Do you have examples on how to solve this?  RadDocument is loaded as a string from DB.

 

Regards Kristian

 

 

 

 

 

Hello,

I'm doing some experiments with WordsProcessing and found an annoying problem.

In a docx document, I have a table in the header. The table height is 2.48cm.
In a test application, I've just opened the document and save it, using your library.
After that, I've opened the document in Word and the table height is not correct as it is only 1.46cm (that's the height of the text inside the table).

Looking at the in-memory data of the document, the height of the table row is set to "Auto".

Unfortunately, there is also a border on this table and it now looks ugly, not counting that the image in the header "crosses" the table border

I also have the same problem in the footer, that also contains a table. In this part, this is more annoying because the height of the footer is not respected and the whole document formatting is not correct.

Hello,

I have a docx template file that contains both MERGEFIELD and CheckBox.

Using version 2021.1.118 of Telerik.Windows.Documents.Flow I perform MailMerge on that document.

After mailmerge the Checkbox control in the output document looses its style when being manually triggered. Manually triggering checkbox in original template does not change original style.

It's expected, that after mailmerge the Checkbox behaves as before mailmerge.

 

The complete demo is here:

While evaluating Telerik.Documents.Spreadsheet.Trial (2021.1.118) I've encountered a bug with registering custom functions in .NET 5.

 

I'm using a console application, and trying to register a couple of functions right at the start of the Main() method. It works like a charm with target framework netcoreapp3.1.

But as soon as I bump the version to net5.0, registering a function throws an exception (I've copied the full stack below).

Perhaps you can guide me what happens? We're currently evaluating on upgrading our license for the latest features, but this thing could be crucial to us, since we need to use .NET 5 for a couple of reasons.

 

I'm calling them right at the start of the applicaption

Before I start down the path of using RadSpreadsheet I want to verify that it will do what I want.  
I would like to use the spreadsheet to do some custom background calculations in a SaaS environment.  The end user would create their own spreadsheets with links to data in their database (maybe using Custom Functions).  The spreadsheet would be calculated in the backend every few minutes, pulling in updated data and solving the spreadsheet.  The output cells (again using Custom Functions) would update the customer's data tables.
Is that a viable use-case for RadSpreadsheet?  I realize the input and output connections to the external data is not part of RadSpreadsheet but it seems like Custom Functions might get me there.
Is there any information on the order of solving calculations in formulas cells?   

How do I get (or "read") a table cell's text value?

For example:

 

In the code above I am trying to iterate through the collection of columns to find the one that contains text «Signature» so that I can replace that text with an image. The beast I could do is use the run as shown above but it never finds the value (although the value is in the table).

Thanks

 

 

 

Is there any support for converting PowerPoint (PPT, PPTX) files to PDF?

Hi,

I would like to export some excel files in a zip without writing on disk.

I have seen ZipLibrary example and I would like to adapt it with excel (if possible).

The idea is to do something like this in "OnClick" event for exemple (see code bellow)

Thanks in advance for your help

Do you have any sample code to set a form field with an image so that the image is centered in the form field but keeps it's aspect ratio without going outside the bounding box? Does the image need to be resized first to reduce filesize?

Thanks.

I am placing a image in a table cell and below the image I will be adding 1 to 3 lines of text.   I have it all working, but have 2 questions.

 

1.  I would like to center the image vertically in the table cell.

 

2. I want to single space the inserted text (paragraph) 

 

Below is my code:

 using (Stream firstImage = File.OpenRead(outputFileName))
                            {
                                var inImage = table1.Rows[x].Cells[y].Blocks.AddParagraph().Inlines.AddImageInline();

                                inImage.Image.Size = new System.Windows.Size(colWidth, colWidth);

                                inImage.Image.LockAspectRatio = true;
                                inImage.Image.ImageSource = new Telerik.Windows.Documents.Media.ImageSource(firstImage, "jpg");
                            }
                            table1.Rows[x].Cells[y].Blocks.AddParagraph().Inlines.AddRun(Path.GetFileNameWithoutExtension(h.fileName)); // filename
