如何重置单选按钮列表中的项目？

Question

Easy one.

I added programatically a few items to a radiuo button list:

foreach (var item in res)
{
     rbl.Items.Add(new ListItem(item.text, item.value.ToString()));
}

After a change of view (Multiview), I need to come back to the view with the radio button list, but this view added again the items.

How can I reset the items already added to the radio button list?

Used, and not working:

rbl.ClearSelection()

rbl.Datasource = null;
rbl.DataBind();

rbl = new RadioButtonList();

Thanks.

Answer 1

The "ClearSelection()" method simply puts the selection to be "-1", in order to remove the data in the list you will need

RadioButtonList1.Items.Clear();

Also be careful, where you actually add the items, that might cause a problem as well, since I cannot see additional code it is just my prediction.

Hope this solves your problem. Cheers!
