missing support for complex DataBinding #11616

Closed VaporiZed closed 2 months ago

VaporiZed commented 2 months ago

Environment

Microsoft Visual Studio Community 2022 (64-Bit) - Preview, Version 17.11.0 Preview 2.1, german language pack

.NET version

.NET 7, .NET 8

Did this work in a previous version of Visual Studio and/or previous .NET release?

not in .NET only in .NET Framework, e.g. 4.8.1

Issue description

If I want to use complex DataBinding for ListBoxes or ComboBoxes, I miss the options to select valid possibilities/properties via the smarttag internal ComboBoxes. I have to input the names of the properties manually. Even worse: The property »selected value« can't be used at all. I have to add a databinding code line into the FormX.Designer.VB by myself. DesignerIssue

Steps to reproduce

  1. create a new WinForms project, either with C# or VB.NET
  2. open the designer of the only existing form
  3. add a ListBox (LB) or a ComboBox (CB) to the form
  4. select the LB/CB and click on the [>] to open the smart tag/advanced control options
  5. activate »use data bound items«
  6. You see just one combobox to select the datasource for the LB/CB. The next three boxes below are just textboxes, which can't be used like the comboboxes in the .NET framework designer to select the databinding-properties of the selected datasource.

There has a known issue in the designer repro to track https://github.com/microsoft/winforms-designer/issues/1209

@VaporiZed designer repo is currently closed source, so we can't see the linked issues.

@VaporiZed We are aware of this issue. There are some internal services that are not available to the out of process designer so some data binding stories are incomplete at the moment. This is known and, on our backlog, but be aware there may be changes in how we recommend databinding in the future.
