Hello, in this video I will talk about declarative component what is declarative component declarative components that you can create your own component which will simplify some business or something in your application. I will give you an example. Now, I have created a simple ADF application with just a department and let us now create a simple page and I will let you know what actually is a component which we will create in this course. And in the same time it does not exist in ADF components. So, I will call for example, this is as depths and the blank page does add a symbol table here So, I will add a new collection and we'll track the table into panic correction okay okay so in the toolbar at add add add ons This is just a symbol it if page was one table entry okay so this is our department table okay let us select department for example it says 500 department and a place to meet what happened this is a default delete button which is coming in EDF It will delete the row from the a traitor but actually zero will be still exist into the database so let's have a look in the database still 500 department is exist you have to press commit after delete so that it will delete sorrow but actually in our in the production application real time application the user needs to see a confirmation confirmation message before deleting Are you sure you want to delete and if the user press ok the row should be physically deleted from the database as well.

So I need to create my own component called delete bottom and once I add this component here by default once this user please delete a bob should open and tell them Are you sure you want to delete and if you submit okay it will delete. So I need to create this my own component which is called delete bottom component. So Nicole's video, we will start creating this delete button. And we need to replace this delete bottom with our custom delete delete button component. So see you next video.
