Solution 1

uncheck all of checked items:

C#

chkitem.ClearSelected();

Uncheck the checked value of a CheckedListBox:

C#

chkitem.SetItemChecked(index, false);

And your code:

C#

foreach (int index in chkitem.CheckedIndices)
{
    chkitem.SetItemChecked(index, false);
}

you can try like this also.

checkedListBox1.Items.Add("value1", CheckState.Unchecked);

For better understanding follow this link. CheckBoxList

Solution-2:

Try like this too.

C#

foreach(int i in checkedListBox1.CheckedIndices)
{
    checkedListBox1.SetItemCheckState(i, CheckState.Unchecked);
}
