Customizing RadGridView Filter Box

[George C.]

Greetings,

Is there a way to hide some of the items of the radgridview filter box, or not showing the filter icon at all (marked with red circles in the attached picture) ?

Hello, George,  

You can hide the entire filter button or hide just some of the filter operators displayed in the popup. I have prepared two sample code snippets for your reference:

Example 1: Hide the filter button: 

        private void radGridView1_ViewCellFormatting(object sender, CellFormattingEventArgs e)
        {
            GridFilterCellElement filterCell = e.CellElement as GridFilterCellElement;
            if (filterCell!=null)
            {
                filterCell.FilterButton.Visibility = ElementVisibility.Collapsed;
            }
        }

Example 2: Hide filter options from the menu: 

        public RadForm1()
        {
            InitializeComponent();
            this.radGridView1.EnableFiltering = true;

            this.radGridView1.ContextMenuOpening+=radGridView1_ContextMenuOpening;
        }

        private void radGridView1_ContextMenuOpening(object sender, ContextMenuOpeningEventArgs e)
        {
            if (e.ContextMenuProvider is GridFilterCellElement)
            {
                foreach (RadItem item in e.ContextMenu.Items)
                {
                    if (item.Text.Contains("Is null")|| item.Text.Contains("Equals"))
                    {
                        item.Visibility = ElementVisibility.Collapsed;
                    }
                }
            }
        }

Feel free to use this approach which suits your requirements best.

I hope this information helps. If you need any further assistance please don't hesitate to contact me.
