Type of Columns

[Frank]

Hello,

how can I find out the Type of the columns? Im going to set the default value of Filteroperator to "Contains" only for the columns with the type string.

Thanks

Hi,

You can use the DataType property of the column currently being filtered.

It seems like this example on teleriks forum:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using Telerik.Windows.Data;
using Telerik.Windows.Controls;
using Telerik.Windows.Controls.GridView;

namespace ChangeDefaultFilterOperator
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();

            var nameColumn = (GridViewBoundColumnBase)this.clubsGrid.Columns[0];
            var customFilteringControl = new MyFilteringControl();
            nameColumn.FilteringControl = customFilteringControl;
        }
    }


    public class MyFilteringControl : FilteringControl
    {
        public override void Prepare(GridViewBoundColumnBase column)
        {
            base.Prepare(column);

            var vm = this.DataContext as FilteringViewModel;

            if (vm != null)
            {
                if (!vm.Filter1.IsActive)
                {
                    vm.Filter1.Operator = FilterOperator.Contains;
                }

                if (!vm.Filter2.IsActive)
                {
                    vm.Filter2.Operator = FilterOperator.Contains;
                }
            }
        }
    }
}

Hello,

Have you tried this:

public override void Prepare(GridViewBoundColumnBase column)
        {
            base.Prepare(column);

            var vm = this.DataContext as FilteringViewModel;

            if (vm != null)
            {
                if (column != null && column.DataType == typeof(string))
                {
                    if (!vm.Filter1.IsActive)
                    {
                        vm.Filter1.Operator = FilterOperator.Contains;
                    }

                    if (!vm.Filter2.IsActive)
                    {
                        vm.Filter2.Operator = FilterOperator.Contains;
                    }
                }
            }

I have tested using that code and it was working fine.
