Question

I try to check multiple values in ASP.NET CheckboxList but I couldn’t.

I Wrote :

chkApplications.SelectedValue = 2;
chkApplications.SelectedValue = 6;

But it just selects item with value ‘6’
What’s wrong ?

Answer 1

The best technique that will work for you is the following:

chkApplications.Items.FindByValue("2").Selected = true;
chkApplications.Items.FindByValue("6").Selected = true;

OR you can simply do it like…

  foreach (ListItem item in chkApplications.Items)
    {
        if (item.Value == "2" || item.Value == "6")
        {
            item.Selected = true;
        }
    }
