Hi
i am trying to add data to a DialogListItem in a (grouped) listview.
This can be done in listview.AddItem by passing the data as 2nd parameter or later on via item.data (which is a getter and setter) see Control Docs and DialogListItem Docs
I am handing the data over in the AddItem method. Then (for test purposes) i try to retrieve the item again via its index. The name of the item is correct, but its data is 0 (even if i try this after showing the dialog).
And if i try to set the data via item.data, i get an A method was called unexpectedly (0x8000ffff) error.
Listviewitem data test.dcf (3.7 KB)
function OnClick(clickData)
{
var dlg = clickData.func.Dlg;
dlg.template = "dialog1";
dlg.Create();
var listview = dlg.Control("listview");
var groups = ["Dates", "Sepcial"];
for(var i = 0; i < groups.length; i++)
{
var group = groups[i];
var createdGroup = listview.AddGroup(group, i);
var addedAtIndex = listview.AddItem("Itemname in " + group, "Data " + i, i);
var retrievedItem = listview.GetItemAt(addedAtIndex);
Log("Item Name: " + retrievedItem.name);
Log("Item Data: " + retrievedItem.data);//This is always 0
//DialogListItem.data Returns or sets the optional data value associated with this item.
//retrievedItem.data = "new try"; //not allowed: A method was called unexpectedly (0x8000ffff)
}
listview.EnableGroupView(true);
Log("\n\nNew try\n\n");
dlg.Show();//no matter if before or after the 2nd loop
for(var i = 0; i < groups.length; i++)
{
var retrievedItem = listview.GetItemAt(i);
Log("Item Name: " + retrievedItem.name);
Log("Item Data: " + retrievedItem.data);
}
//dlg.Show();//could also be here
}
function Log(msg) { DOpus.Output(String(msg)); }
This code produces the following output
Item Name: Itemname in Dates
Item Data: 0
Item Name: Itemname in Sepcial
Item Data: 0
New try
Item Name: Itemname in Dates
Item Data: 0
Item Name: Itemname in Sepcial
Item Data: 0
Expected ouput for data should be Data 0 or Data 1
