Hi,

I can't seem to find the SelectedIndexChanging event on Windows form control Check Listbox. Is there any way to get the event before the selectedIndexChanged or tell what the previous selected index was?

Thanks

I check box list there is no events SelectedIndexChanging. because you can select multiple items by clicking on checkbox to checked.
do you want to get previously checked items whenever you checked/unchecked any items from check box list?

Well what I have is a list of certificates stored in a check list box, for each certificate the user can select a specific Start or End Date. Now when the user leaves that specifc text box I would like to check if it has been checked and then save that certificate and Start/End date. If that makes sence.

Maybe I should just pop a new windows which promps the user for a Start and End Date?

Hi Bardy,

Please you can use following code:

C#

private void checkedListBox1_ItemCheck(object sender, ItemCheckEventArgs e)
        {
            if (e.NewValue == CheckState.Checked)
            {
                //You can save the selected item into databse
                //Yor Popup should comes here...
                MessageBox.Show("Selected item is: " + checkedListBox1.Text);
            }
            else
            {
                //you can remove the item from database
            }
        }

Please do let me know, if you have any doubt.

Please provide Vote if this would be helpful to you.

Thanks,
