Programmatically Select Item in Asp.Net ListView

Question

After doing a quick search I can\'t find the answer to this seemingly simple thing to do.

How do I Manually Select An Item in an Asp.Net ListView? <

Answer 1

You can set the ListViews SelectedIndex

list.SelectedIndex = dataItem.DisplayIndex; // don't know which index you need
list.SelectedIndex = dataItem.DataItemIndex; 

Update

If your loading the data on page load you may have to traverse the data to find the index then set the SelectedIndex value before calling the DataBind() method.

public void Page_Load(object sender, EventArgs e)
{
  var myData = MyDataSource.GetPeople();
  list.DataSource = myData;
  list.SelectedIndex = myData.FirstIndexOf(p => p.Name.Equals("Bob", StringComparison.InvariantCultureIgnoreCase));
  list.DataBind();
}


public static class EnumerableExtensions
{
    public static int FirstIndexOf(this IEnumerable source, Predicate predicate)
    {
        int count = 0;
        foreach(var item in source)
        {
            if (predicate(item))
                return count;
            count++;
        }
        return -1;
    }
}
