how to find if the check box list is selected or not in asp.net

int roleselected = ckl_EditRole.Items.SelectedIndex;

For CheckBoxList, SelectedIndex will give you just the first selected index in the CheckBoxList. If it's not -1, then something was selected. This may be enough for what you're looking for.

if( ckl_EditRole.SelectedIndex != -1 )
{
// Do Something
}

But, since the CheckBoxList can have multiple selections, you probably want to loop through the Items and look for the selected ones.

foreach( ListItem li in ckl_EditRole.Items )
{
    if( li.Selected )
    {
        // Do Something
    }
}
