n2cms editable checkboxlist property
I am looking at creating an editable checkboxlist property for an item as indicated in the code below. The edit interface renders the checkboxlist but does not persist the selected checkbox items.
[Editable("Divisions", typeof(CheckBoxList), "SelectedValue", 85, DataBind = true, ContainerName = Tabs.Content)]
[EditorModifier("DataSource", new string[] { "Item 1", "Item 2", "Item 3", "Item 4", "Item 5", "Item 6" })]
public virtual string[] Divisions
开发者_JAVA技巧 {
get { return (string[])(GetDetail("Divisions")); }
set { SetDetail("Divisions", value); }
}
Has anyone else tried to implement the above? If so, how did you achieve it?
Thank you for your time and support

After spending a few hours checking out n2cms custom editors, below is my solution
public class EditableCheckBoxListAttribute : AbstractEditableAttribute
{
public override void UpdateEditor(N2.ContentItem item, Control editor)
{
CheckBoxList lst = editor as CheckBoxList;
if (lst != null)
{
foreach(ListItem li in lst.Items)
{
if (item[this.Name].ToString().Contains(li.Value))
{
li.Selected = true;
}
}
}
}
public override bool UpdateItem(N2.ContentItem item, Control editor)
{
CheckBoxList lst = editor as CheckBoxList;
ArrayList items = new ArrayList();
foreach (ListItem li in lst.Items)
{
if (li.Selected)
{
items.Add(li.Value);
}
}
string[] itemID = (string[])items.ToArray(typeof(string));
item[this.Name] = String.Join(",",itemID);
return true;
}
protected override Control AddEditor(Control container)
{
CheckBoxList lst = new CheckBoxList();
var items = N2.Find.Items
.Where.Type.Eq(typeof(TestItem))
.Filters(new NavigationFilter())
.Select<TestItem>();
foreach (TestItem i in items)
{
lst.Items.Add(new ListItem(i.Title, i.ID.ToString()));
}
container.Controls.Add(lst);
return lst;
}
}
And this is how you use it
[EditableCheckBoxList(Title = "Items")]
public virtual string Items
{
get { return (string)(GetDetail("Items", "")); }
set { SetDetail("Items", value, ""); }
}
As an added bonus, here is a radio button list editable attribute
public class EditableRadioListAttribute : AbstractEditableAttribute
{
public override void UpdateEditor(N2.ContentItem item, Control editor)
{
RadioButtonList rbl = editor as RadioButtonList;
if (rbl != null)
{
rbl.SelectedValue = item[this.Name].ToString();
if (rbl.Items.FindByValue(item[this.Name].ToString()) != null)
{
rbl.Items.FindByValue(item[this.Name].ToString()).Selected = true;
}
}
}
public override bool UpdateItem(N2.ContentItem item, Control editor)
{
RadioButtonList rbl = editor as RadioButtonList;
string itemID = rbl.SelectedValue;
item[this.Name] = itemID;
return true;
}
protected override Control AddEditor(Control container)
{
RadioButtonList rbl = new RadioButtonList();
var items = N2.Find.Items
.Where.Type.Eq(typeof(TestItem))
.Filters(new NavigationFilter())
.Select<TestItem>();
foreach (TestItem i in items)
{
rbl.Items.Add(new ListItem(i.Title, i.ID.ToString()));
}
container.Controls.Add(rbl);
return rbl;
}
}
And this is how you use it
[EditableRadioListAttribute(Title = "Item")]
public virtual string Item
{
get { return (string)(GetDetail("Item", "")); }
set { SetDetail("Item", value, ""); }
}
Hope this helps

Libardo answered this on the forum http://n2cms.codeplex.com/Thread/View.aspx?ThreadId=223192
Here is tutorial on dropdowns http://n2cmstutorial.blogspot.com/2010/08/creating-page-with-drop-down-list.html and it should not be too hard to implement checkbox list following these steps.
