Save ComboBox to Database and retrieve the information back.

Question

I am trying to Save database information from a Combobox to a database and then retrieve the information back to the User.

I am already able to Save to the database. The step I am struggling with is to push the information from the database back to the app and to show the information from the database combobox. I have already tried using Databinding withing c sharp this does not solve the problem.

Any help will be appreciated.

Regards

hello pelumi your are binding your combobox using window property this method is correct but there is one problem with this method is that it will not update you combobox if any type of the updation is performed in DB because this method fetched the data from DM when form is loaded. if you want to update your combobox if any type of the updation is performed then you must be bind your combobox manually . You can achive this by 2 method: 1. create a method which first insert the data into table and after that fetch the data from table and insert into combobox . It will perform two operation so it is little bit slow for this you can use second method. 2. Create an trigger in DB for updation which fetch the data from table when any type of the updatio is performed in tbale this method is little fast compare to first......

I will be using approach 1. Is this the right way to programatically bind to the database. https://msdn.microsoft.com/en-us/library/ms742863%28v=vs.110%29.aspx If you have any other sites in mind that would help. Regards

I havent binding the Combobox programatically. As I am unsure how to do this. All I have done is use the binding source within properties window to access the Database and then use the ComboBox that way. The information gets saved to the Database but it isnt pulled back to the application. Any help will be appreciated. Regards
