in the dropdownlist component, the select event triggers multiple times when rendering in a client-side web assembly project.

<SfDropDownList TValue="string" TItem="Data" Placeholder="e.g: Aero" AllowFiltering=true IgnoreAccent=true DataSource="@Country">

    <DropDownListFieldSettings Value="Name"></DropDownListFieldSettings>

    <DropDownListEvents TValue="string" OnValueSelect="DataSelected"></DropDownListEvents>


<br />

<input type="text" @bind-value="Count" />

@code {

    public int Count { get; set; } = 0;

    public class Data


        public string Name { get; set; }


    public StringBuilder events = new StringBuilder();

    List<Data> Country = new List<Data>


        new Data() { Name = "Aeróbics"},

        new Data() { Name = "Aeróbics en Agua"},

        new Data() { Name = "Aerografía"},

        new Data() { Name = "Águilas"},

        new Data() { Name = "Ajedrez"},

        new Data() { Name = "Ala Delta"},

        new Data() { Name = "Álbumes de Música"},

        new Data() { Name = "Alusivos"},

        new Data() { Name = "Análisis de Escritura a Mano"},


    private void DataSelected(Syncfusion.Blazor.DropDowns.SelectEventArgs args)





Replication procedure :

1. Run the sample with the above code in the client-side hosted sample.

2. open the popup and choose one value

3. check the event count in the input element.

4. again open the popup and select the any one value

5. check the event cont now.

Expected: input element count should be 2

Output: input element count is 7
