WPF: How to hide GridViewColumn using XAML?

Question

I have the following object in App.xaml

Answer 1

You best bet is probably to create a custom control by inheriting from the GridView class, adding the required columns, and exposing a meaningful property to show/hide a particular column. Your custom GridView class could look like this:

using System;
using System.Windows.Controls;

namespace MyProject.CustomControls
{
    public class CustomGridView : GridView
    {
        private GridViewColumn _fixedColumn;
        private GridViewColumn _optionalColumn;

        public CustomGridView()
        {
            this._fixedColumn = new GridViewColumn() { Header = "Fixed Column" };
            this._optionalColumn = new GridViewColumn() { Header = "Optional Column" };

            this.Columns.Add(_fixedColumn);
            this.Columns.Add(_optionalColumn);
        }

        public bool ShowOptionalColumn
        {
            get { return _optionalColumn.Width > 0; }
            set
            {
                // When 'False' hides the entire column
                // otherwise its width will be set to 'Auto'
                _optionalColumn.Width = (!value) ? 0 : Double.NaN;
            }
        }

    }
}

Then you can simply set that property from XAML like in this example:

Optionally, you could make the 'CustomGridView.ShowOptionalColumn' a DependencyProperty to be able to use it as a binding target.
