I bind my Mobile:List with dataset that contains 3 fields A B & C. How can I
display list with text A + " " + B + " " + C.

I know must use OnDataBind event, but I don't know how to get values of the
fields.

You're correct, although the actual name of the event is ItemDataBind
(declared as OnItemDataBind on the control tag).=20

When you register an event handler for this event, your event is raised
for every item that gets databound. Your handler is passed an argument
with the type ListDataBindEventArgs, which has two properties. The
first, ListItem, gives you the item in the list that is being databound.
The second, DataItem, gives you the data item to which the item is being
databound.=20

In the case of databinding to a dataset, the DataItem will be a DataRow.
You could cast the DataItem value to a DataRow, and use DataRow
properties to look up the values you need, as follows:

void List_ItemDataBind(Object sender, ListDataBindEventArgs e)
{
DataRow row =3D (DataRow)e.DataItem;
e.ListItem.Text =3D String.Format("{0} {1} {2}", row["A"], row["B"],
row["C"]);
}

A few ways:

- Declaratively create a ItemTemplate and within create the following
    DataBinder.Eval(((ListItem)Container).DataItem, "A") "Text"
DataBinder.Eval(((ListItem)Container).DataItem, "B") "Text"
DataBinder.Eval(((ListItem)Container).DataItem, "B") "Text"<br>

- Programmatically. Handle the OnItemDataBind event and add a format
string to assign the text of the list item
    e.ListItem.Text =3D String.Format("{0} text {1} text {2}",
                    DataBinder.Eval(e.DataItem,
"A"),
                    DataBinder.Eval(e.DataItem,
"B"),
                    DataBinder.Eval(e.DataItem, "C")
);

And just before I post this I see Shanku gave more details on #2.

Hope this helps
