Question Blazor Server App - How to set currency based on selection?

[raysefo]

Hi,

I have a Blazor Server Application, on one of my Blazor pages I am using a Radzen data grid. There is a currency dropdown on the data grid. I want to change the Unit Cost currency based on selection. The problem is If I change one of the row's currency, all of the row's currency is set to the selected one. How can I fix this?

Here is the page;

<RadzenDataGridColumn TItem="OrderDetail" Property="Currency" Title="Currency">
                                <EditTemplate Context="orderDetail">
                                   <RadzenDropDown AllowClear="true" TValue="string" Class="w-100" Data=@currency @bind-Value="orderDetail.Currency" Name="Currency" Change=@(args => OnChange(args))/>
                                    <RadzenRequiredValidator Text="Currency is required" Component="Currency" Popup="true" Style="position: absolute"/>
                                </EditTemplate>
                            </RadzenDataGridColumn>
                            <RadzenDataGridColumn TItem="OrderDetail" Property="UnitCost" Title="Unit Cost">
                                <EditTemplate Context="orderDetail">
                                    @*<RadzenNumeric TValue="double" Min="1" @bind-Value="orderDetail.UnitCost" Style="width: 100%; display: block" Name="UnitCost"/>
                                    <RadzenRequiredValidator Text="Unit Cost is required" Component="UnitCost" Popup="true" Style="position: absolute"/>*@
                                    @switch (SelectedCurrency)
                                    {
                                        case "Dolar":
                                            @string.Format(new CultureInfo("en-US"), "{0:C}", orderDetail.BuyQuantity * orderDetail.CostRatio)
                                            break;
                                        case "Euro":
                                            @string.Format(new CultureInfo("en-FR"), "{0:C}", orderDetail.BuyQuantity * orderDetail.CostRatio)
                                            break;
                                        default:

Currently on my phone, so I can't quite see everything in the code, but it feels like you have a single SelectedCurrency for the entire page, instead of a SelectedCurrency for each item.

You are right
