This blog will show you how to take a screenshot with Blazor WebAssembly. There is currently no way to take a screenshot in Blazor. So, in this blog, I'll use the Javascript library html2canvas to capture and download the screenshot.
The code below is an index.razor code. In the source code. To use Javascript functions, IJSRuntime is injected. To collect the message, I've added a textbox. This message will be captured in the screenshot. Two new buttons have been added. The first is to take a screenshot, and the second is to download the screenshot. Two methods for taking and downloading screenshots have been added to the @code area. The Javascript methods Takeshot and DownloadImg do not return any values, So I use the InvokeVoidAsync method to call them.
The code for the index.html file is shown below. Inside the <body> tag, I've added the html2canvas.min.js cdn and SampleJavaScript.js script tags. As a result, the html2canvas javascript files and SampleJavaScript.js will be loaded.
The output of the above code is shown below. When the user clicks the Take button, the message is captured, and when the user clicks the Download button, the image is downloaded.
This blog is going to illustrate how to implement Entity Framework (EF) Core with SQL Server LocalDB. The Entity Framework Core enables access to data from the database. This allows developers to avoid having to write most of the data access code. And the SQL Server LocalDB works similarly to the SQL SERVER with few features. You can get the LocalDB when you install visual studio or visual studio express. You can find the .mdf and _log.ldf files in the C:/Users/{user} directory. Let see how to create a SQL Server LocalDB and implement Entity Framework Core Step 1: The first step is to add a connection. In the menu -> click Tools and select Connect to Database It will display the Add Connection window. Enter (localdb)\mssqllocaldb in the server name textbox. Then in the Select or enter a database, select master and click ok Now in the server explorer, you can find the master DB containing Tables, Views, Stored
Azure Functions is a serverless computing service provided by Microsoft Azure, enabling developers to create applications without worrying about server maintenance and infrastructure. Using Azure Functions, developers can create event-driven, scalable, and highly available applications. In this blog, we will explain how to create an Azure function using Visual Studio 2022 with C# as the programming language. Before we begin, there are some prerequisites to consider. You will need an active Azure account subscription, Visual Studio 2022, and Azure Functions and Azure Storage extensions for Visual Studio. Step 1: Creating a new Azure Functions project in Visual Studio To create a new project, open Visual Studio 2022 and click on "Create a new project". In the "Create a new project" window, search for "Azure Functions" and select "Azure Functions" from the list of project templates. Next, enter the project name, which
Introduction: Blazor is a powerful framework for building web applications using C# instead of JavaScript. It allows developers to create interactive and dynamic user interfaces with ease. One of the key features in Blazor is the EventCallback<T> pattern, which enables communication between components through events. In this blog post, we will explore how to use the EventCallback<T> pattern in Blazor by building a simple example. Creating the Event-Driven Component: Let's start by creating a Blazor component called MyComponent. This component will raise an event when a button is clicked. Here's the code for the MyComponent.razor file: MyComponent.razor < h3 > My Component < / h3 > < button @onclick = " RaiseEvent " > Raise Event < / button > @code { [ Parameter ] public EventCallback < string > EventRaised { get ; set ; } private async Task RaiseEvent ( ) { await EventRais
