I have a check list box in wpf. With some email ids populated using public ObservableCollection<BoolStringClass> TheList { get; set; } method at runtime.

When user save the record the selecetd email ids are saved in database(123@gmail.com;456@yahoo.co.in;789@rediff.com).. and so on with comma separated.

Now when I want to reload the data on to controls from database, how can I keep checked the items stored in database ? In windows forms its easy to achieve this, but how this can be done in wpf?

    What is wpf stopping to you which you can perform with Winform? – Hari Prasad Jan 21 '16 at 06:27

  • Joshua, the answer u provided is for geting the selected item in listbox. I want that I have a datatable with thosed items that are present in list box also. I am looking for something like this foreach( var o in listEmailsIds.Items) { string v = o.ToString(); if (emailID.ToString() == v) //emailID is from database { v.ischecked = true; } – user5370906 Jan 21 '16 at 06:46

Better have the ObservableCollection of EmailItem and have string and IsSelected property. Bind the collection to check box list. And Set IsSelected based on whether they are saved in database

    @HariPrasad Why? Does this not answer the question? Admittedly, it would be better if this answer went into more depth (and maybe provided an example) but it *is* an answer. – Joshua Shearer Jan 21 '16 at 06:34

  • http://stackoverflow.com/questions/17381741/get-all-selected-items-from-wpf-checkbox-list-give-me-error This has example with datatable instead of class, but using same approach to add the IsChecked column to the datatable – Mahesh Malpani Jan 21 '16 at 08:47
