Can I convert a boolean to Yes/No in a ASP.NET GridView

Question

I have a ASP.NET GridView with a column mapped to a boolean. I want do display \"Yes\"/\"No\" instead of \"True\"/\"False\". Well actually I want \"Ja\"/\"Nej\"

Answer 1

Add a method to your page class like this:

public string YesNo(bool active) 
{
  return active ? "Yes" : "No";
}

And then in your TemplateField you Bind using this method:

<%# YesNo(Active) %>

Answer 2

I had the same need as the original poster, except that my client's db schema is a nullable bit (ie, allows for True/False/NULL). Here's some code I wrote to both display Yes/No and handle potential nulls.

Code-Behind:

public string ConvertNullableBoolToYesNo(object pBool)
{
    if (pBool != null)
    {
        return (bool)pBool ? "Yes" : "No";
    }
    else
    {
        return "No";
    }
}

Front-End:

<%# ConvertNullableBoolToYesNo(Eval("YOUR_FIELD"))%>

Answer 3

It's easy with Format()-Function

Format(aBoolean, "YES/NO")
