C Updating Datagrid Wpf Stack Overflow I'm having an issue with a wpf datagrid's datagridtemplatecolumn and updating the items that display on the combobox based off of a user's interaction. since the program is database bound, it does.

Wpf Datagrid Custom Combobox Not Updating Stack Overflow This issue reported here uses partial code, and i would merge them except the controls being worked with are different. see : resolved clearing textbox with mvvm for full code. here is my completed code working, the problem was i need to raise a property change event from the model and the viewmodel, im not sure if this is the ebst approach?. The fix disconnected all bindings when exiting editing. in your case that sets combobox.itemssource to null, which raises a selectionchanged event. you can easily ignore this event by testing whether combobox.itemssource is null. If i set up a new wpf application in visual studio 2010 and add the following code xaml, a data grid opens with comboboxes inside. the problem now is that changeing a value through a combobox does not get propagated to the bound data model. Edit: i think your first solution works because of setting the datacontext in xaml. i assume that datacontext=" {binding relativesource= {relativesource self}, path=.}" is execute when calling initializecomponent (); and because your liststring property is just an autoproperty and not implement inotifypropertychanged your mainwindowview does.

My datagrid has two colums, a text column and a combobox column. when the text column changes the setter for the appropriate property is called however when the combobox changes the setter for that property is not called any ideas where i am going wrong?. Hi everyone, i'n new to programing and i need some help with mvvm datagrid and updating the datagrid combobox items source update after inserting data to the database: public partial class novamedida : observableobject { [observableproperty] [notifypropertychangedfor (nameof (descricaonovamedida))] string descricaon;. The best way to start off with is to have in your case a container such as a datatable that has generid column (not to be displayed) and a datagridviewcomboboxcolumn with the datasource set to the text for gender. Ah, so it looks like you are not updating the selected item in your combo box anymore by binding to the list view's selected item. you are just updating the text in the combobox by binding to the list view's selected item.
