If you've ever used Airbnb to book a place, you'll find out in the process that the company has a top product design team. The enterprise, which is changing the entire industry, is providing users with a seamless experience, and this is the original intention of writing this article today.
As a product designer who likes to study user experience, interactive design, and UI, I particularly like to dissect successful products, looking for hidden intera

First, prefaceHave you ever met some designers, fascinated by some cool animations, and loved to design cute and fluid animations based on the scene? But in real-world work, even developers think these animations are great, but we know that the more customized the animation, the more cumbersome and time-consuming it will be to achieve it. This sometimes leads to contradictions between designers and engineers.And since Airbnb developed the Lottie, desi

A dataset, also known as a data set, data set, or data set, is a collection composed of data. A Data Set (or dataset) is a collection of data, usually in the form of tables.
DatasetIt does not directly deal with the database. The interaction between the database and the database is provided through. NET data.ProgramThe data adapter object in. How does a dataset
Take the table name "MyTable" and the field FirstName varchar (30) and FamilyName varchar (30) as an example.
Non-strong (UnTyped) Dataset does not need to define the attributes of each field of the corresponding table in advance, you can directly obtain the values from the queried result set (non-strong (UnTyped) Dataset), for example:String lFirstName =LDs. Table ["MyTable"]. Rows [0] ["FirstName"]. ToStr

Are you talking about typed dataset and untyped dataset?
Typed Dataset is derived from dataset. It generates a dataset Based on the predefined data schema and imposes a strong type constraint on fields in the dataset. You can see
In actual scenarios, you may need to query the table sheets in the database at a time,
Fill the dataset with the fill method of the sqldataadapter class, and specify the name of the able table filled in the dataset,
For example, set it to the same as the database.
You can use the tablemappings attribute of the sqldataadapter class.
