Binding value of database

[Luigi]

Hello,

when I save the data of my customer, the data is saved correctly, my field Document_Type=1 or 2 or 3 depend by dropdownlist.

When reload the record the dropdownlist not bind correctly the record value, show always the first choice.

This my code:

<SfDropDownList TItem="_TipoDocumento" TValue="string"

                    PopupHeight="230px"

                    @bind-Index="@ddlIndex"

                    Placeholder="Seleziona Tipo documento"

                    DataSource="@_TipoDocumento.TipoDocumentos"

                    FloatLabelType="@FloatLabelType.Always"

                    @bind-Value="@objClienti.TipoDocumento">

      <DropDownListFieldSettings Text="Text" Value="ID"></DropDownListFieldSettings>

    </SfDropDownList>

Hi Luigi, 

We suggest you to enable the EnablePresistance property to persist the selected value in the component. 

https://help.syncfusion.com/cr/blazor/Syncfusion.Blazor.DropDowns.SfDropDownBase-1.html#Syncfusion_Blazor_DropDowns_SfDropDownBase_1_EnablePersistence 

SfDropDownList ID="AutoComplete" TItem="GameFields" TValue="string" @bind-Index="@ddlIndex" EnablePersistence="true" PopupHeight="230px" Placeholder="Seleziona Tipo documento" @bind-Value="@DropDownValue" DataSource="@Games" FloatLabelType="@FloatLabelType.Always"> 

    <DropDownListFieldSettings Text="Text" Value="Text" /> 

</SfDropDownList> 

 

@code { 

    private int? ddlIndex { get; set; } = 0; 

}
