Can I convert a boolean to Yes/No in a ASP.NET GridView
I use this code for VB:
<asp:TemplateField HeaderText="Active" SortExpression="Active">
<ItemTemplate><%#IIf(Boolean.Parse(Eval("Active").ToString()), "Yes", "No")%></ItemTemplate>
</asp:TemplateField>
And this should work for C# (untested):
<asp:TemplateField HeaderText="Active" SortExpression="Active">
<ItemTemplate><%# (Boolean.Parse(Eval("Active").ToString())) ? "Yes" : "No" %></ItemTemplate>
</asp:TemplateField>
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) %>
Nope - but you could use a template column:
<script runat="server">
TResult Eval<T, TResult>(string field, Func<T, TResult> converter) {
object o = DataBinder.Eval(Container.DataItem, field);
if (converter == null) {
return (TResult)o;
}
return converter((T)o);
}
</script>
<asp:TemplateField>
<ItemTemplate>
<%# Eval<bool, string>("Active", b => b ? "Yes" : "No") %>
</ItemTemplate>
</asp:TemplateField>
You could use a Mixin.
/// <summary>
/// Adds "mixins" to the Boolean class.
/// </summary>
public static class BooleanMixins
{
/// <summary>
/// Converts the value of this instance to its equivalent string representation (either "Yes" or "No").
/// </summary>
/// <param name="boolean"></param>
/// <returns>string</returns>
public static string ToYesNoString(this Boolean boolean)
{
return boolean ? "Yes" : "No";
}
}
Or you can use the ItemDataBound
event in the code behind.
