Fix: Binding Class to ASP.NET GridView Column

 To bind a class to an ASP.NET GridView column, you typically use a TemplateField. Here are the steps to do this:


1. Create a Class: First, create a class that represents the data structure you want to bind to the GridView column. For example:


```csharp

public class Product

{

    public int ProductID { get; set; }

    public string ProductName { get; set; }

    public decimal Price { get; set; }

}

```


2. Define GridView and TemplateField: In your ASP.NET page, define a GridView control and the TemplateField for the column you want to bind with the class. Set the ItemTemplate to display the property from the class. For example:


```html

<asp:GridView ID="GridView1" runat="server">

    <Columns>

        <asp:TemplateField HeaderText="Product ID">

            <ItemTemplate>

                <asp:Label Text='<%# Eval("ProductID") %>' runat="server" />

            </ItemTemplate>

        </asp:TemplateField>

        <asp:TemplateField HeaderText="Product Name">

            <ItemTemplate>

                <asp:Label Text='<%# Eval("ProductName") %>' runat="server" />

            </ItemTemplate>

        </asp:TemplateField>

        <asp:TemplateField HeaderText="Price">

            <ItemTemplate>

                <asp:Label Text='<%# Eval("Price") %>' runat="server" />

            </ItemTemplate>

        </asp:TemplateField>

    </Columns>

</asp:GridView>

```


3. Data Binding: In your code-behind file (C#), bind the GridView to a List of your class. For example:


```csharp

protected void Page_Load(object sender, EventArgs e)

{

    if (!IsPostBack)

    {

        List<Product> products = new List<Product>

        {

            new Product { ProductID = 1, ProductName = "Product 1", Price = 19.99M },

            new Product { ProductID = 2, ProductName = "Product 2", Price = 29.99M },

            // Add more products as needed

        };


        GridView1.DataSource = products;

        GridView1.DataBind();

    }

}

```


This code will bind the GridView columns to the properties of the `Product` class. You can extend this example by adding more columns and classes as needed for your specific scenario.

bad character U+002D '-' in my helm template

 In Helm templates, the hyphen character (`-`) can sometimes be treated as a reserved character, particularly when defining values or labels. To include a hyphen character in a Helm template without issues, you can use one of the following approaches: 1. **Quoting the Hyphen:**    You can enclose the hyphen in double quotes, like this:    ```yaml    key: "-"    ```    This way, Helm will interpret the hyphen as a string rather than an operator. 2. **Using Backticks:**    If you need to use the hyphen within a Go template function or inside backticks, you can escape it with a backslash (`\`), like this:    ```yaml    value: `{{ .Values.someField | printf "%s \\-" }}`    ```    The backslash prevents Helm from interpreting the hyphen as a special character. 3. **Variable Assignment:**    Assign the value to a variable and use it. For example:    ```yaml    {{- $hyphen := "-" }}    key: {{ $hyphen }}    ```    This way, you can use the variable `$hyphen` wher

GitLab pipeline stopped working with invalid yaml error

 When your GitLab pipeline has stopped working with an "invalid YAML" error, it means there's a problem with your `.gitlab-ci.yml` file. This could be due to syntax errors, incorrect indentation, or other issues in your pipeline configuration. Here's how to troubleshoot and resolve this issue: 1. **Check for Syntax Errors**:    Carefully review your `.gitlab-ci.yml` file for any syntax errors. Common issues include missing colons, indentation problems, or mismatched quotation marks. Use a YAML linter or an online YAML validator to identify and correct syntax errors. 2. **Indentation**:    YAML relies heavily on proper indentation. Make sure that all lines within the same block have consistent indentation (typically using spaces, not tabs). Incorrect indentation can cause YAML parsing errors. 3. **Dashes and Lists**:    Ensure that you use the correct syntax for lists (arrays) in YAML by starting each item with a dash (`-`). Be consistent with your use of dashes throug

How do I add a printer in OpenSUSE which is being shared by a CUPS print server?

 To add a printer in openSUSE that is being shared by a CUPS print server, you can use the following steps: 1. **Ensure CUPS Client is Installed:**    Make sure your openSUSE system has the CUPS client tools installed. You can install them using the following command:    ```bash    sudo zypper install cups-client    ``` 2. **Discover Available Printers:**    Use the `lpinfo` command to discover available printers on your CUPS print server. Replace `cups-server-hostname` with the hostname or IP address of your CUPS server:    ```bash    lpinfo -v -h cups-server-hostname:631    ```    This command should list the printers shared by the CUPS server. 3. **Add a Printer:**    Use the `lpadmin` command to add a printer. Replace `printer-name` with the name of the printer you want to add and `printer-uri` with the URI obtained from the `lpinfo` command:    ```bash    sudo lpadmin -p printer-name -E -v printer-uri    ```    For example:    ```bash    sudo lpadmin -p MyPrinter -E -v socket://cu
