Inherited Members
Namespace: Syncfusion.Blazor.DropDowns
Assembly: Syncfusion.Blazor.dll
Syntax
public class MultiSelectChangeEventArgs<T>
Type Parameters
Name Description
T

The type of the new value (typically string or a collection of selected values).
Remarks

The MultiSelectChangeEventArgs class is useful to detect changes in value/selection (including add/remove), and provides both the previous and new value so you can identify exactly what changed. Most properties are read-only except Value for downstream logic.

Examples
void MultiSelectChanged(MultiSelectChangeEventArgs<string[]> args)
{
  if (!args.IsInteracted) return;
  // Audit or react to change in args.Value vs args.OldValue
}
