Questions on UI for WinForms Forum

Hi Telerik support team,

I’ve a question about the GridView for Winforms. In my grid I’ve a combobox column which is based on a enum. Before, in net framework 4.7.2 I had a nice wrapper around it in order to translate the values. Works like a charm.

Now we’ve updated our application to net8 and that part does not work anymore. I’ve isolated the code in a simple example program. The attached solution contains 2 projects, one is net framework and the other is net8. Code is the same. In the net8 I get an exception when I try to set a filter on the column.

Are you aware of this? Did I miss something? How can I get this working in net8?

Any help is welcome.

Regards,

Daniel Kaya

Group by ID but sort by Date RadGridView

as per the title I group records by groupID, but the records also contain dates, I in turn would like to order the groups by "creation date" without creating other subgroups, leaving the grouping by groupID unchanged.

Currently I use this code for grouping:

GroupDescriptor descriptor = new();
descriptor.GroupNames.Add("GroupID", ListSortDirection.Descending);
this.DGNotes.GroupDescriptors.Add(descriptor);

I tried using examples in the documentation but to no avail. Thanks for your help.

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

Carl
