Display string value instead of boolean checkbox using datasource? - sql-server

Question

Boolean is for storing economically in SQL Database. But the datagridview when using datasource function in C# just show true or false by the checkbox each row.
I want to display the string value in the datagridview, not Boolean using checkbox .
True = "Spin On"
False = "Element"
How can I change the checkbox to a string value?

Answer 1

You have at least two options to obtain this:
Binding
First, you could change the binding during on RowDataBound of GridView. Give a look at this example, where you have the following class:
public class Student
{
public int Roll { get; set; }
public string Name { get; set; }
public bool Status { get; set; }
}
and you can change the default behavior of GridView as follows:
/// <summary>
/// Handles the RowDataBound event of the GridView2 control.
/// </summary>
/// <param name="sender">The source of the event.</param>
/// <param name="e">The <see cref="System.Web.UI.WebControls.GridViewRowEventArgs"/> instance containing the event data.</param>
protected void GridView2_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
Student s = (Student)e.Row.DataItem;
if (s.Status == true)
{
e.Row.Cells[2].Text = "1";
}
else
{
e.Row.Cells[2].Text = "0";
}
}
}
Formatting
Another way to address this problem consists in using custom formatting, handling the CellFormatting event according to your needs:
void gridView2_CellFormatting(object s, DataGridViewCellFormattingEventArgs evt)
{
if (evt.ColumnIndex == yourcolumnIndex){
if (evt.Value is bool){
evt.Value = ((bool)evt.Value) ? "Yes" : "No";
evt.FormattingApplied = true;
}
}
}

Answer 2

Using a Converter will allow you to do it easily
using System;
using System.Windows.Data;
namespace WpfApplication2
{
[ValueConversion(typeof(Boolean), typeof(String))]
internal class BooleanToStringConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
Boolean state = (Boolean)value;
return state ? "Spin On" : "Element";
}
public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
throw new NotImplementedException();
}
}
}
then, in your XAML, bind your String (a label in my example) to the Boolean ('state' variable in the example) using the Converter :
<Label Content="{Binding State, Converter={StaticResource BooleanToStringConverter }, Mode=OneWay}" />
