Setting the ColumnDefinitions/RowDefinitions properties of a Grid panel is only possible if the value is string as the ColumnDefinitionCollection/RowDefinitionCollection types do not have a public constructor #11273
Description
Description
With the .NET 10 version, a new functionality to simplify the definition of ColumnDefinition and RowDefinition instances for the Grid panel was introduced. The changes come from this issue.
Now, the ColumnDefinitions/RowDefinitions properties have a set method introduced with this change. However, the ColumnDefinitionCollection/RowDefinitionCollection types cannot be instantiated as they do not have a public constructor. Hence, the only possible approach is to use string as a value or create instances of ColumnDefinition/RowDefinition to be added one by one via the Add method..
Reproduction Steps
- Create a .NET 10 WPF application
- Add the following code
Grid grid = new Grid(); grid.ColumnDefinitions = new ColumnDefinitionCollection();
Expected behavior
To not be limited to using only a value of the type of string to set the ColumnDefinitionCollection/RowDefinitionCollection properties.
Actual behavior
The ColumnDefinitionCollection/RowDefinitionCollection do not have a public constructor, hence they cannot be instantiated, and this forces the use of a value of the type of string, or create instances of ColumnDefinition/RowDefinition to be added one by one via the Add method.
