Here's a simple example:
razor
`
In the child component `Child1`, you can then define a CascadingParameter:
razor
`
And in `Child2`, you can use it like so:
razor
@CascadingValue
`
This way, the `Child2` component can access the value of `Parameter` passed from its ancestor without needing to explicitly pass it through each intermediate child.
How can I restart proxmox vm everytime it shuts down
To automatically restart a Proxmox VM every time it shuts down, you can use the `qm set` command with the `-onboot 1` option. This will ensure that your virtual machine (VM) is started automatically when Proxmox boots.
Here's how you can do it:
bash
qm set
`
Replace `
### Example:
If you have a VM with an ID of `100`, you would run:
bash
qm set 100 -onboot 1
`
This command tells Proxmox to start VM `100` every time it boots.
### Additional Options
- **Autostart on Host Boot**: The `-onboot 1` option ensures that the VM starts automatically when Proxmox itself boots.
### Important Notes
- Ensure your VM has a valid boot disk and BIOS settings configured correctly to allow it to start up properly.
By following these steps, you can ensure that your Proxmox VM is automatically restarted every time the host machine shuts down.
No, when the vm shuts down on its own. I want proxmox to restart it.
To configure Proxmox VE (PVE) so that a virtual machine (VM) restarts automatically when it shuts down on its own, you can use the `onboot` parameter in the VM's configuration. This parameter is set to `1` by default for most virtual machines when they are created, but if it has been changed or not explicitly set, you can add it manually.
Here’s how to do it:
1. Log in to the Proxmox VE web interface.
2. Navigate to your node and then click on "Virtual Environment".
3. Find the VM you want to configure for automatic restarts, select it, and click on its ID.
4. Go to the "Hardware" tab at the top of the page.
5. Click on `Add` in the lower left corner and select a disk (`SCSI Controller`) if it's not already set up for your VM.
6. Find or create an empty file (e.g., `emptyfile`).
7. Click on the "Options" tab and look for a disk with your VM's root partition.
8. Add or modify the following line in the `config` section of that disk:
`
onboot=1
`
Alternatively, you can edit the VM's configuration file directly. The path to this file is typically `/etc/pve/qemu-server/
1. Open the configuration file with a text editor (e.g., nano, vim):
`
sudo nano /etc/pve/qemu-server/
`
2. Add or modify the following line under the `options` section:
`
onboot=1
`
3. Save and close the file.
4. Restart Proxmox VE to apply changes (optional):
`
sudo systemctl restart pve-cluster
`
After making these changes, your VM should automatically start again when it shuts down on its own.
How do I pull bootrap 5 content right
To pull Bootstrap 5 content to the right, you can use CSS classes provided by Bootstrap. Specifically, you can apply the `ms-auto` class (margin-start: auto) or directly set a margin-left with pixel values to push content towards the right.
Here's an example using Bootstrap classes:
html
This text will be aligned to the right.
This text will be aligned to the right.
This text will be aligned to the right.
`
In these examples, `container` is a Bootstrap utility class that provides padding and horizontal centering. The content inside the inner div will be aligned to the right due to either setting an inline style, using `margin-left: auto;`, or applying Bootstrap's utility class `.ms-auto`.
How do I get current path ins asp.net core View
To get the current path in an ASP.NET Core view, you can use `ViewBag` or a custom helper method. Here's how to do it using both methods:
### Method 1: Using ViewBag
1. **In your controller, set the current path in `ViewBag`:**
`csharp
public IActionResult YourAction()
{
string currentPath = HttpContext.Request.Path.Value;
ViewBag.CurrentPath = currentPath;
return View();
}
`
2. **In your view, access the `ViewBag` value:**
`html
Current Path: @ViewBag.CurrentPath
`
### Method 2: Using a Custom Helper Method
1. **Create a custom helper method in your `HelperExtensions.cs` file (or any other appropriate location):**
`csharp
public static class HelperExtensions
{
public static string GetCurrentPath(this IHtmlHelper html)
{
return html.ViewContext.HttpContext.Request.Path.Value;
}
}
`
2. **In your view, use the custom helper method:**
`html
Current Path: @Html.GetCurrentPath()
`
Both methods will give you access to the current path in your ASP.NET Core view.
Visual studio a breakpoint cannot be inserted at this position
Visual Studio does not allow breakpoints to be set in certain positions, such as inside a method call or on the left margin of an empty line. To insert a breakpoint at another position:
1. Click to the right of the code editor window, in the gutter area next to your source code.
2. The line number will turn blue when you click on it.
If this option is not available:
- Ensure that debugging mode is turned on (Debug -> Start Debugging or press F5).
- Check if the code file you are trying to debug has breakpoints enabled. You can disable all existing breakpoints by clicking on "Debug" in the menu and then selecting "Disable All Breakpoints."
- Make sure that your code is not within a compiled method, such as inside another class or function.
- If you are debugging an external application (e.g., web services), ensure that the correct project is selected in Solution Explorer and set as the startup project.
If none of these steps resolve your issue, you may need to consult Visual Studio's documentation or seek further assistance from community forums.
How do you pass parameters in the blazore component
To pass parameters to a Blazor component, you can use attributes in the markup. Here's an example:
razor
`
In this case, `MyComponent` is a Blazor component and it accepts a parameter named `ParameterName`. The value of the parameter can be set to "Parameter Value".
Expand on this topic: Why is blazor component not rendering in the Asp.Net Core View? You need to call a component from a View like
To render a Blazor component in an ASP.NET Core view, you need to follow several steps. Here's how it can be done:
1. **Add the necessary namespaces**: First, ensure that your Razor Pages or views have access to Blazor components by adding `@using Microsoft.AspNetCore.Components` and any other relevant namespaces at the top of your view file.
2. **Create a custom tag helper**: Blazor components cannot be directly used in HTML views like ASP.NET Core MVC Views. To render a component, you need to create a custom tag helper.
Here's an example of how you can create and use such a tag helper:
3. **Create the Tag Helper**:
csharp
// Create this class in any folder, e.g., TagHelpers/BlazorComponentTagHelper.cs
using Microsoft.AspNetCore.Razor.TagHelpers;
using System.Threading.Tasks;
public class BlazorComponentTagHelper : TagHelper
{
private readonly IWebHostEnvironment _env;
public BlazorComponentTagHelper(IWebHostEnvironment env)
=> this._env = env ?? throw new ArgumentNullException(nameof(env));
[HtmlAttributeName("type")]
public Type ComponentType { get; set; }
[HtmlAttributeNotBound]
public string RenderMode { get => "ServerPrerendered"; } // You can change this to Client or other modes if needed
[HtmlAttributeName("params")]
public string ComponentParams { get; set; }
///
public override async Task ProcessAsync(TagHelperContext context, TagHelperOutput output)
{
if (this.ComponentType == null) throw new ArgumentNullException(nameof(this.ComponentType));
var componentId = Guid.NewGuid().ToString();
// Create the script tag to load Blazor runtime
output.Content.AppendHtml($"");
// Create the div where Blazor component will be rendered
output.Content.AppendHtml($"
");
// Initialize and render the Blazor component using JavaScript interop
await context.JsRuntime.InvokeVoidAsync("Blazor.renderComponent", this.RenderMode, new { elementId = componentId }, ComponentType);
}
}
`
4. **Register the Tag Helper**:
In your `Startup.cs` or equivalent configuration file, add services and middleware to register tag helpers:
csharp
// Startup.cs
public void ConfigureServices(IServiceCollection services)
{
// Other service registrations...
// Register Tag Helpers
services.AddTagHelperAssemblies(typeof(BlazorComponentTagHelper).Assembly);
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
// Other middleware configurations...
if (env.IsDevelopment())
app.UseDeveloperExceptionPage();
else
{
app.UseExceptionHandler("/Home/Error");
app.UseHsts();
}
// Use Tag Helpers middleware before MVC Middleware (important)
}
`
5. **Use the Custom Tag Helper in your View**:
html
@using Microsoft.AspNetCore.Components
`
6. **Ensure Blazor Server is running on the server**: Your ASP.NET Core application must be set up to host a Blazor WebAssembly or Server app.
By following these steps, you should be able to render your custom Blazor component within an ASP.NET Core view. This approach uses a combination of Razor Tag Helpers and JavaScript interop for seamless integration between the two technologies.
Remember to handle any potential issues related to CORS if your Blazor app is hosted on a different domain or port from your ASP.NET Core application.
How do I pass just a normal string into blazor component as a parameter. It is still complaining thinking the string I passed in should be an object.
To pass a normal string into a Blazor component as a parameter, you need to ensure that the type of the parameter in your component matches the type of value being passed. If it's complaining and expecting an object instead, make sure:
1. The property or method accepting the string is indeed defined as a `string` type.
2. You are passing in a value of type `string`.
Here's an example:
razor
@page "/my-component"
@InputString
@code {
[Parameter]
public string InputString { get; set; }
}
`
And in your calling component or page, you can pass the `string` like this:
razor
@page "/parent-component"
`
If the parameter is not being recognized as a `string`, make sure there are no typos and that you're passing in the value correctly. If it's still giving issues, double-check your component definition to ensure everything is set up properly for accepting string parameters.
If this doesn't resolve the issue and you're using a more complex scenario or additional context, please provide further details so I can assist you better.
Should I pass in the string as this? typeof(@Model).ToString()
No, you should not pass in the string exactly like that. Instead, you can use reflection to get the type of `@Model` and then convert it to a string using `ToString()`. Here is an example:
`
string modelType = typeof(@Model).FullName;
