Hi, I have a user control with a checkedListBox and one button. I show this fill this popup on dataGridView1_CellDoubleClick event (I'll post code below) on popup button click I want to use bindingSource.Filter.

I tried it from this user control button_click event but it was doing nothing then I made a method in the form where there is the datagridview and still nothing. So I need help on how to get column name and than make method which can filter bindingSource.

Please help me. I am using C# 3.5 WinForms

This is the user control button code:

private void button1_Click(object sender, EventArgs e)
    {
        OperatorsForm of = new OperatorsForm();
        var checkedvalues = checkedListBox1.CheckedItems.Cast<string>().Select(s => "'" + s + "%'").ToArray();
        string  d = "LoadName LIKE " + string.Join(" or ", checkedvalues);
        of.filter(d);
    }

This is popup code :

private void dataGridView1_CellDoubleClick_1(object sender, DataGridViewCellEventArgs e)
    {
        UserControl1 ucontrol = new UserControl1();
        var button = sender as DataGridView;

        HashSet<string> strings = new HashSet<string>();
        for (int i = 0; i < dataGridView1.Rows.Count - 1; i++)
        {
            strings.Add(dataGridView1.Rows[i].Cells[e.ColumnIndex].Value.ToString());
        }

        checkedListBox1.Items.AddRange(strings.ToArray());
        ucontrol.FillList(strings.ToList());

        var listViewItems = strings.Select(x => new ListViewItem(x, 0)).ToArray();

        ListView listView = new ListView();
        listView.View = View.SmallIcon;
        listView.MultiSelect = false;

        listView.Items.AddRange(listViewItems);

        int itemToShow = 18;
        var lastItemToShow = listViewItems.Take(itemToShow).Last();
        int height = lastItemToShow.Bounds.Bottom + listView.Margin.Top;
        listView.Height = height;
        var popup = new ToolStripDropDown();
        popup.AutoSize = false;
        popup.Margin = Padding.Empty;
        popup.Padding = Padding.Empty;
        ToolStripControlHost host = new ToolStripControlHost(ucontrol);
        host.Margin = Padding.Empty;
        host.Padding = Padding.Empty;
        host.AutoSize = false;
        host.Size = ucontrol.Size;
        popup.Size = ucontrol.Size;
        popup.Items.Add(host);

        popup.Show(this, dataGridView1.Top, dataGridView1.Top);
    }
