Date Range Picker for Blazor
This date range picker component is a port of js DateRangePicker, rewritten using C# as a Razor Component. It creates a dropdown menu from which a user can select a range of dates.
There is no dependency with jquery, moment, or bootstrap
Features include limiting the selectable date range, localizable strings and date formats, a single date picker mode, and predefined date ranges.
JS Interop is used for popup positioning and outside click handling. With future releases of ASP.NET Core Blazor it will be possible without js.

Custom buttons:
<DateRangePicker @bind-StartDate="StartDate" @bind-EndDate="EndDate">
<ButtonsTemplate>
<button class="cancelBtn btn btn-sm btn-default"
@onclick="@context.ClickCancel" type="button">Cancel</button>
<button class="cancelBtn btn btn-sm btn-default"

@code {
DateTimeOffset? StartDate { get; set; }
DateTimeOffset? EndDate { get; set; }
void ResetClick(MouseEventArgs e, DateRangePicker picker)
{
StartDate = null;
EndDate = null;
// Close the picker
picker.Close();
// Fire OnRangeSelectEvent
picker.OnRangeSelect.InvokeAsync(new DateRange());
}
}Use Picker.TStartDate and Picker.TEndDate properties to get current picker state before a user clicks the 'apply' button.
#Startup.cs
using BlazorDateRangePicker;
//ConfigureServices
services.AddDateRangePicker(config =>
{
config.Attributes = new Dictionary<string, object>
{
{ "class", "form-control form-control-sm" }
};
});It's possible to create multiple named config instances and bind it to picker with "Config" property.
services.AddDateRangePicker(config => ..., configName: "CustomConfig");

DateRange:
public class DateRange
{
public DateTimeOffset Start { get; set; }
public DateTimeOffset End { get; set; }
}Note: DateRange Start and End is in local timezone.
