Namespace: DevExpress.XtraReports.Web.ReportDesigner.Services
Assembly: DevExpress.XtraReports.v24.2.Web.dll
NuGet Package: DevExpress.Web.Reporting.Common
#Declaration
#Remarks
Register a service that implements the IFormatStringStorage
interface to add a format string to the list of DateTime format strings available in the Format String Editor.
The following code snippet implements a service that adds a d
format string to the strings shown in the DateTime category:
using System;
using System.Collections.Generic;
using DevExpress.XtraReports.Web.ReportDesigner.Services;
public class CustomFormatStringStorage : IFormatStringStorage {
protected Dictionary<string, string[]> CustomSet { get; private set; }
public virtual Dictionary<string, string[]> GetAllPatterns() {
CustomSet = new Dictionary<string, string[]> {
{ "System.DateTime", new string[] { "d" } }
};
return CustomSet;
}
public bool Save(string typeString, string pattern) {
return false;
}
public bool Remove(string typeString, string pattern) {
return false;
}
}
Register the service at application startup:
using Microsoft.AspNetCore.Builder;
using DevExpress.XtraReports.Web.ReportDesigner.Services;
var builder = WebApplication.CreateBuilder(args);
// ...
builder.Services.AddScoped<IFormatStringStorage, CustomFormatStringStorage>();
using DevExpress.XtraReports.Web.ReportDesigner.Services;
// ...
protected void Application_Start() {
// ...
DefaultReportDesignerContainer.Register<IFormatStringStorage, CustomFormatStringStorage>();
}
