c# - Two-way binding an ObservableCollection<string> to WPF DataGrid -


i've been tying different things / reading on issue awhile , have not yet found answer. guys can help.

i have observablecollection of type string. want bind collection datagrid , able edit/delete/add collection. here xaml:

<datagrid itemssource="{binding movies.titles}"  canuserdeleterows="true" canuseraddrows="true" height="300">     <datagrid.columns>         <datagridtextcolumn binding="{binding path=datacontext, relativesource={relativesource self}}"/>     </datagrid.columns> </datagrid> 

the same observablecollection bound listbox. want able edit collection using datagrid method (above) , see changes/edits in listbox. delete/add working correctly, when edit string inside grid cell , loses focus, string goes , never gets updated.

thanks lot / suggestions.

wow, went yesterday , stuck datagrid add new line observablecollection. after research, realized why. strings , immutable.

i found question , unfortunately didn't have answer. can't leave empty of answer.

so here answers found:

  1. datagrid cannot update string collection adding, editing, or removing strings.

  2. i found workaround wrap string in stringwrapper object. here is.

    public class stringwrapper { public string text { get; set; } }

i didn't either answer.

the original question asker, moncadad, looks wants 1 column datagrid. wants add , remove strings observablecollection without lot of code. edit isn't important since can done delete , add again.

i ended doing myself reusable usercontrol made called stringlistbox.

a listbox strings supports add , delete

basically idea create of datagrid label, listbox, textbox , add button , since control, has work observableobject or list in 1 control.

this give add , delete. doesn't provide edit.

hope helps next guy.
