SharePoint List View Threshold Error while Fetching 5000+ Records in list.
I am fetching data from a SharePoint list that contains more than 5000 records inside my function. While retrieving the data, I am getting the following error: “Flow Reminders→ The attempted operation is prohibited because it exceeds the list view threshold.” Scenario: The SharePoint list has 5000+ items. Data is being fetched programmatically. The error occurs during query execution. What I need help with What is the recommended and best-practice approach to retrieve large datasets from a SharePoint list without hitting the list view threshold? Questions: What is the recommended approach to fetch large data from a SharePoint list without hitting the list view threshold? Any suggestions, examples, or documentation references would be greatly appreciated. Thanks.
It appears and error that does not exist
I am using VS 2022 Community and when i develope asp.net apps it happens sometimes that it appears an error that does not exist adn only after many hours of searching for the error or rewriting the same code the app begins to run correctly. Somehitng simmilar happened to any of you ? how can i avoid these strange behaviour of the compiler ? Thank you in advance Luis MartinConnect .Net (4.6.2) to Dataverse using the Dataverse plugin
Hi Microsoft Tech Community, We have a Dataverse environment in our tenant, and I have its URL. I'm building a .NET application and need to connect it to Dataverse for data access. From the Learn docs, ChatGPT, and Copilot, it seems I need to use an App ID (Client ID) and Client Secret in the connection string (e.g., via Microsoft.PowerPlatform.Dataverse.Client). However, the Dataverse environment itself doesn't expose any App ID or Client Secret—where would I even find those if they exist? Here's the code snippet we found online that's using OAuth with AppId and RedirectUri, but we're unsure about the app registration part: using Microsoft.Crm.Sdk.Messages; using Microsoft.PowerPlatform.Dataverse.Client; using Microsoft.Xrm.Sdk; class Program { // TODO Enter your Dataverse environment's URL and logon info. static string url = "https://yourorg.crm.dynamics.com"; static string userName = "email address removed for privacy reasons"; static string password = "yourPassword"; // This service connection string uses the info provided above. // The AppId and RedirectUri are provided for sample code testing. static string connectionString = $@" AuthType = OAuth; Url = {url}; UserName = {userName}; Password = {password}; AppId = 51f81489-12ee-4a9e-aaae-a2591f45987d; RedirectUri = app://58145B91-0C36-4500-8554-080854F2AC97; LoginPrompt=Auto; RequireNewInstance = True"; static void Main() { //ServiceClient implements IOrganizationService interface IOrganizationService service = new ServiceClient(connectionString); var response = (WhoAmIResponse)service.Execute(new WhoAmIRequest()); Console.WriteLine($"User ID is {response.UserId}."); // Pause the console so it does not close. Console.WriteLine("Press the <Enter> key to exit."); Console.ReadLine(); } } Do I need to create a separate app registration in Microsoft Entra ID (Azure AD), link it to the Dataverse environment (perhaps as an application user?), and then use that app's Client ID/Secret in my .NET code? If so, could someone outline the exact steps, including permissions and Power Platform admin center setup? Any guidance or links to official walkthroughs would be greatly appreciated—thanks!Build Scalable Web Apps and APIs with ASP.NET Core, Blazor, Angular for Modern Web Apps
I’m starting this discussion because many developers today need guidance on how to build modern, scalable web applications and APIs by combining ASP.NET Core, Blazor, and Angular—three powerful technologies within the .NET ecosystem. Whether you're focused on server-side development, creating dynamic client-side apps, or integrating both, these frameworks provide incredible capabilities to enhance your projects ASP.NET Core for API Development: ASP.NET Core is a robust, high-performance framework that allows you to create powerful APIs. Some of the best practices we’ll cover include: - Designing RESTful APIs with ASP.NET Core - Utilizing Entity Framework Core for efficient database access - Securing APIs with JWT and OAuth - Handling asynchronous requests for optimal performance - Implementing API versioning and changes over time Building Dynamic Web Apps with Blazor: Blazor enables you to create interactive web applications using C# instead of JavaScript. We will discuss: - Blazor Web Assembly vs. Blazor Server: Differences and use cases - Creating reusable Blazor components for UI - Integrating third-party JavaScript libraries with Blazor - Using SignalR for real-time features - Optimizing Blazor for performance Angular for Full-Featured Client-Side Development: Angular is a powerful, full-featured front-end framework that excels in creating dynamic and complex user interfaces. In this section, we'll dive into: - Why you might choose Angular over Blazor in certain cases - Using Angular CLI to scaffold, build, and maintain apps - Managing state in Angular with NgRx or RxJS - Connecting Angular with ASP.NET Core APIs for data handling - Working with Angular components, services, and routing for a seamless user experience Combining Angular and Blazor in a Single Application: You may have use cases where you want to combine both Blazor and Angular in one application to leverage the strengths of each framework: - When to use Angular for complex frontend features (e.g., dynamic forms, complex data visualization) and Blazor for simpler components or backend-heavy apps. - Managing communication between Angular and Blazor components in a single page (e.g., using - JavaScript Interop to pass data between the two). - Handling authentication and state management across both frameworks. Integration between Frontend (Blazor/Angular) and Backend (ASP.NET Core): No matter whether you're using Angular or Blazor for the frontend, integrating these with your backend API is key. We'll discuss: - Setting up HttpClient for making API calls from both Blazor and Angular - Working with SignalR to enable real-time features in both frontends - Managing authentication and authorization across both Angular and Blazor (JWT, OAuth) - Best practices for passing data and sharing state between the frontend and backend Scalable and Maintainable Web Apps: When building full-stack web applications, it's important to focus on scalability and maintainability. Here are some practices for achieving this: - Structuring your application code to separate concerns (e.g., services, components, repositories) - Utilizing Dependency Injection for flexible and testable code - Modularizing your codebase for easier updates and maintenance - Using Lazy Loading for Angular and Blazor components to improve performance - Leveraging Caching strategies to enhance response times Testing and Continuous Deployment: For any modern application, testing and deployment are crucial. We’ll discuss: - Unit and integration testing in ASP.NET Core, Blazor, and Angular - Automated end-to-end testing (e.g., with Cypress for Angular, bUnit for Blazor) - Continuous Integration/Continuous Deployment (CI/CD) strategies for seamless deployment to cloud platforms like Azure or AWS When to Choose Angular, Blazor, or Both: It’s essential and interesting to know when to use each of these frameworks depending on your project’s needs. Some scenarios we’ll explore: - When to go for Blazor for a unified C# experience in both frontend and backend - Why you might opt for Angular when building highly interactive, feature-rich web applications - Hybrid approaches where you can use Blazor and Angular together for a robust full-stack solution SO: Combining ASP.NET Core, Blazor, and Angular allows developers to choose the right tool for the right job, creating flexible, scalable, and maintainable web applications. Whether you’re leveraging Blazor for its deep integration with .NET or Angular for its powerful frontend capabilities, these technologies offer a powerful suite of tools to build modern web applications. What are your thoughts? How have you integrated Angular or Blazor with ASP.NET Core in your projects? Share your experiences and challenges, and let's collaborate on solutions!
aspnet c# iterate control in listview and remove a panel from placeholder in one column
trying to iterate through controls in listview to remove panel01 from placeholder if detected row in database condition dt.Rows[i]["BidEndWithError"].ToString() == "no" in the row: But all the listview's panel01 being removed even dt.Rows[i]["BidEndWithError"].ToString() == "no" is not 'no'`your text` `<asp:PlaceHolder ID="phLabel" runat="server"> <asp:Panel ID="panel01" runat="server"> Day Left : <%# Eval("BidDayLeft") %></br> Hour Left : <%# Eval("BidHourLeft") %></br> Minute Left : <%# Eval("BidMinuteLeft") %></br> Second Left : <%# Eval("BidSecondLeft") %></br> </asp:Panel> protected void lv01_ItemDataBound(object sender, ListViewItemEventArgs e) { if (e.Item.ItemType == ListViewItemType.DataItem) { string constr = ConfigurationManager.ConnectionStrings["bidsystemdb"].ConnectionString; using (SqlConnection con = new SqlConnection(constr)) { DataTable dt = new DataTable(); //string strSQL = "Select * from BidTable2 WHERE ProductName='Toy 1'"; string strSQL = "Select * from BidTable2"; SqlDataAdapter adpt = new SqlDataAdapter(strSQL, con); adpt.Fill(dt); for (int ij = 0; ij < e.Item.Controls.Count; ij++) { for (int i = 0; i < dt.Rows.Count; i++) { //Response.Write("lv01 reached!"); if (dt.Rows[i]["BidEndWithError"].ToString() == "no") { Response.Write("lv01 level 2 reached!"); PlaceHolder _phLabel = e.Item.Controls[ij].FindControl("phLabel") as PlaceHolder; Panel _pnlLabel = e.Item.Controls[ij].FindControl("panel01") as Panel; _phLabel.Controls.Remove(_pnlLabel); ContentPlaceHolder _MainContent = Master.FindControl("MainContent") as ContentPlaceHolder; UpdatePanel _udp01 = _MainContent.FindControl("udp01") as UpdatePanel; _udp01.Update(); } } } } } }`Enable .Net ImageFormat.WebP in VS 2022 Prof ASPX Web.Config
Hi. I am developing C# ASPX Web sites in VS Professional 2022 (64 bit). I want to access the System.Drawing.Imaging.ImageFormat.WebP property so I can manipulate WebP files. I believe this requires .Net 4.8. I know there are 3rd party libraries out there - I would prefer to keep as much native MS code as possible. I am unable to get System.Drawing.Imaging.ImageFormat.WebP as a selection option for the ImageFormat. I can get all of the other formats e.g. TheImageFormat = System.Drawing.Imaging.ImageFormat.Jpeg/Gif/Png etc. WebP is not shown as an option. I have Web.Config set as: <compilation optimizeCompilations="true" debug="true" targetFramework="4.8.1"> <assemblies> <add assembly="System.Net, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A" /> <add assembly="System.Numerics, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089" /> </assemblies> </compilation> <httpRuntime targetFramework="4.8.1" executionTimeout="240" maxRequestLength="20480" requestValidationMode="2.0" /> The Targeting Packs & SDK seem to be installed & enabled as per the screen snap below. Any help in resolving this is greatly appreciated. Many thanks, Peter.
