Sir- Great Video- One addition to the deselect All ---> Instead of looping to selected=false we can also use .ClearSelection() option
Thanks

Thank you a lot for your great and clear explanation, great video, I am looking for a quick demo about how to populate a listbox items based on selecting an item from a drop down list, I thin that it is should be done thru DB connection , but I have no clue how :(

Thank you Sir,
we can also use the method ClearSelection() of the CheckBoxList object to deselect all the items.

Great video. Just in my opinion I think the deselect all can be more efficient by setting the index of the checkbox list to -1 instead of looping. CheckBoxList1.SelectedIndex = -1;

i want to create a function where when Admin check/uncheck the checkboxs in the gridview it will Activate/Deactivate the user, and the value (Activate/Deactivate) will be stored inside database (sql server 2008). How exactly do i do that? Can you please make a tutorial on it? Thank You very much.

cmbEmail.Items.Add(dr[0].ToString() + " | " + dr[1].ToString());
}
}

MessageBox.Show(ex.Message);
}
}
private void combobox_SelectedIndexChanged(object sender, EventArgs e)
