UltraComboEditor CheckedListSettings Cannot manually set check state.
posted

I am using the CheckedListSettings for the UltraComboEditor.  I get it set up and I can select multiple items, however, I also need to be able to manually (programmatically) set some of the items as checked or unchecked.  I set the CheckState property on the ValueList accordingly but it simply does NOT work.  If I set it to the Indeterminate state that shows up, however, I cannot Check a specific item.  Also setting the Value property seems to do nothing.  I am using the latest version of the Infragistics WinForms controls (10.3).

    Hello,

    I have tried the following and it does work for me:

    ultraComboEditor1.Value = new object[]{"val1", "val2"};

    where the "val1" and "val2" are the values from the column that I am assigning as a "ValueMember" .

            public Form1()
            {
                InitializeComponent();
                DataTable dt = new DataTable();
                dt.Columns.Add("String", typeof(string));
                dt.Columns.Add("String1", typeof(string));

                dt.Rows.Add("a", "val1");
                dt.Rows.Add("b", "rr");
                dt.Rows.Add("c", "pp");
                dt.Rows.Add("d", "gg");
                dt.Rows.Add("e", "val2");

                ultraComboEditor1.DataSource = dt;
                ultraComboEditor1.DisplayMember = "String";
                ultraComboEditor1.ValueMember = "String1";

                ultraComboEditor1.CheckedListSettings.CheckBoxStyle = Infragistics.Win.CheckStyle.CheckBox;
                ultraComboEditor1.CheckedListSettings.CheckBoxAlignment = ContentAlignment.MiddleRight;

                ultraComboEditor1.CheckedListSettings.EditorValueSource = Infragistics.Win.EditorWithComboValueSource.CheckedItems;

                ultraComboEditor1.CheckedListSettings.ListSeparator = ", ";

                ultraComboEditor1.CheckedListSettings.ItemCheckArea = Infragistics.Win.ItemCheckArea.CheckBox;
            }

            private void button1_Click(object sender, EventArgs e)
            {
                ultraComboEditor1.Value = new object[]{"val1", "val2"};
            }

    Please let me know if you have any further questions.
