Tim,

Thank you for pointing me in the right direction. I had not seen the sourcecode for the providers yet. Only two weeks ago I started to learn C#, so I am still somewhat unfamiliar with the source code.

However, it seems that only the value of the first checked checkbox is saved on the node, using Tim's PublishFormAsPage WorkFlow as well as the built-in 'Save as umbraco document' WorkFlow.

Is it so that the values of a checkbox list are stored as a strings of comma separated values in dbo.UFRecordFields[DataTypes]? What if the DataType on the node is not a textstring, but the very same checkbox list as used as a PreValue Source in Contour?

P.S. it turns out Contour 1.1.12 is in use, not 1.1.2.

Tim,

I downloaded the source code and I managed to get it to work. Here is part of my solution:

        public override System.Web.UI.WebControls.WebControl Editor
        {
            get
            {
                cbl = new Umbraco.Forms.Core.Controls.ValidateableCheckBoxList();
                cbl.CssClass = "checkboxlist";
                cbl.RepeatLayout = System.Web.UI.WebControls.RepeatLayout.Flow;

                if (this.AssociatedField.PreValueSource != null)
                {
                    foreach (var prevalue in this.AssociatedField.PreValueSource.Type.GetPreValues(this.AssociatedField))
                    {
                        String value = Data.DictionaryHelper.GetText(prevalue.Value).Trim();

                        System.Web.UI.WebControls.ListItem item = new System.Web.UI.WebControls.ListItem(value, prevalue.Id.ToString());
                     
                        if (String.IsNullOrEmpty(DefaultValue))
                        {
                        // no DefaultValue
                            // check both keys and values
                            if (_value.Contains(value) || _value.Contains(prevalue.Id.ToString()))
                            {
                                item.Selected = true;
                            }
                        }
                        else
                        {
                        // DefaultValue
                            // loop through the stored values of a comma separated string
                            foreach (String val in ParseTokens(DefaultValue).Split(','))
                            {
                                // check both keys and values
                                if (val.Contains(value) || val.Contains(prevalue.Id.ToString()))
                                {
                                    item.Selected = true;
                                }
                            }
                        }
                        cbl.Items.Add(item);
                    }
                }
                return cbl;
            }
            set
            {
                base.Editor = value;
            }
        }

It has room for improvement, e.g. when each checkbox is checked the value is compared to all stored values in a comma separated string.
