I have the following problem, I want the RadzenDropDown element to be as wide as the country code, for example "DE for Germany.
When the RadzenDropDown is opened, I would like to see the complete content of the image and name. The width of the original RadzenDropDown should be included
not be negotiated.
<RadzenDropDown AllowClear="true" @bind-Value=SelectedCountry AllowFiltering="true" Data=@Countries
LoadData=@LoadData
TextProperty="@nameof(Country.DescriptionLong)"
ValueProperty="@nameof(Country.DescriptionShort)"
Style=@DropDownStyle
TValue="string"
Name="@Name">
@if (!string.IsNullOrWhiteSpace(item.FlagUrl))
{
}
@item.DescriptionLong
@if (!string.IsNullOrWhiteSpace(item.FlagUrl) && !OnlyLiterals)
{
}
@GetDescription(item)
@code {
private string _selectedCountry = "";
[Parameter]
public string SelectedCountry { get; set; } = "";
[Parameter]
public string Name { get; set; } = "";
[Parameter(CaptureUnmatchedValues = true)]
public Dictionary<string, object>? AdditionalAttributes { get; set; }
[Parameter]
public EventCallback<string> SelectedCountryChanged { get; set; }
[Parameter]
public bool OnlyLiterals { get; set; }
private Guid _componentKey = Guid.NewGuid();
private IEnumerable<Country> Countries { get; set; } = new List<Country>();
private string DropDownStyle => OnlyLiterals ? "width: 100px;" : "width: 100%;";
protected override void OnParametersSet()
{
if (SelectedCountry != _selectedCountry)
{
_selectedCountry = SelectedCountry;
if (SelectedCountry != null)
{
_selectedCountry = SelectedCountry;
}
SelectedCountryChanged.InvokeAsync(SelectedCountry);
}
}
protected override void OnInitialized()
{
Countries = CountriesService.GetEuropeanCountries().OrderBy(c => c.SortOrder).ThenBy(c => c.DescriptionLong);
}
private void LoadData(LoadDataArgs args)
{
var query = Countries.AsQueryable();
if (!string.IsNullOrEmpty(args.Filter))
{
query = query.Where(c => c.DescriptionLong.ToLower().Contains(args.Filter.ToLower()));
}
Countries = query.OrderBy(c => c.SortOrder).ThenBy(c => c.DescriptionLong).ToList();
InvokeAsync(StateHasChanged);
}
private string GetDescription(Country country)
{
return OnlyLiterals ? country.DescriptionShort.Substring(3) : country.DescriptionLong;
}
}
