PDF Markup/Annotation Settings?

We have incomming PDF documents that have been annotated/marked up/stamped (we beleive using Adobe). When you view or print from Telerik the "annotations" are missing or wrongly formated.

Chrome and Edge both display the PDF correctly.

Are there any properties or techniques I can use to get Telerik PDF to include the annotations ?

Attached are the original PDF "PDFMarkUp.pdf" and the PDF as printed by Telerik "PDFMarkUpOUT.pdf" (Replicates the Telerik View )

How to use AutoCompleteDataSource with RadCheckedDropDownList

I have a situation where I would like to customize the list of items provided by the auto-completion suggestion list in a RadCheckedDropDownList. i.e. Even though radCheckedDropDownList1.DataSource is set to one list of values, I need to set radCheckedDropDownList1.AutoCompleteDataSource to a different list of values. Whenever I attempt to do this, the auto-complete drop-down list still shows suggestions from the DataSource collection rather than the AutoCompleteDataSource collection.

If I attempt the same thing with a normal RadDropDownList, it works fine. Is this functionality not supported with a RadCheckedDropDownList? If not, why have an AutoCompleteDataSource property? If it is supported, what is the proper usage to get it work?

Thanks!

Change position of add a new Row and Custom Filtering Row

Hi everyone,

Does anyone know how to change the position of the "Add New Row" and the "Custom Filtering Row"?

Currently, the standard layout is as shown in the image below. I'd like to position the "Custom Filtering Row" just below the header and the "Add New Row" below the "Custom Filtering Row."

Visual Studio 2022 crashes in Telerik WinForms Converter extension

Hello,

Visual Studio 2022 is still crashing in some situations like form renaming, saving assembly information or refactoring. In revision notes for main Telerik extensions, I can see some crashes were fixed in 2024.3.808 version. But it's still crashing, but in WinForms Converter extension, last version is 2024.3.805, and I don't see any update. I have disabled that extension for now, I am not using it, so it's not a problem for me. Will you update also this extension?

RadMaskedEditBox mask setting

I have a MaskedEditBox called mtbText bound to a string property like this:

mtbText.DataBindings.Add(nameof(mtbText.Value), customerSearch, nameof(customerSearch.Text), false, DataSourceUpdateMode.OnPropertyChanged);

public string? Text
{
get => _text;
set
{
if (_text != value)
{
_text = value;
OnPropertyChanged(nameof(Text));
}
}
}

Sometimes I need a specific mask like SSN or phone # and sometimes I don't. The UI resets the properties on the single mask control depending on need. If I bind to a specific mask like this (say a SSN or phone #) it works fine. However sometimes I need a mask that will allow anything. I tried aaaaaaaaaa and a few other combination but these won't let me enter blank spaces. If I set the MaskType to None it allow the spaces but doesn't bind to the property.

mtbText.Mask = string.IsNullOrEmpty(item.Mask) ? "aaaaaaaaaa" : item.Mask;

mtbText.MaskType = MaskType.Standard;

mtbText.TextMaskFormat = MaskFormat.ExcludePromptAndLiterals;

What mask can I use that would allow me to enter something like 123 Main Street and still bind to the object property.

Thanks

Gridview gets and losses focus every x seconds

Hi Telerik support team,

I got into problems with a gridview. It seems that the grid losses focus and directly gets focus back. This happens every 1 or 2 seconds. I’ve created a small application with a simple grid with datasource and handlers for the Got- and LostFocus. Add a breakpoint on it and it will hit constantly.

My problem gets bigger because the datasource also gets kind of refreshed. In the sample application I’ve a class Person. Put there a breakpoint on the Name getter and every second or 2 it will hit.

Start the application, don’t click around, just wait. The breakpoints will hit.

What’s happening with the focus on the grid?? Why is it getting ‘stolen’? Can I prevent this behavior?

In the sample application look into the FocusIssueForm.

Regards,

Daniel

oongDescriptionEtudeGeneral:ChargeCodeSociete('Affiche').

RETURN.

END METHOD.

IN oongDescriptionEtudeGenral FORM

CASE ipcMode:
WHEN 'InitBe' THEN DO:
beSociete= NEW fichier.description_etude.be.beSociete().

beSociete:ReadbeSociete(OUTPUT DATASET dsSoc).

//Associer le query du dataset au probadingSource
bsSociete:HANDLE = DATASET dsSoc:HANDLE.
END.
