DataSet union DataTable

The project is an example of joining two DataTables using a DataSet. One of the tables is the main table, the second is nested.

Basic steps:

1. Declaration of DataSet and DataTable.
2. Creating a DataSet structure and adding tables with names.
3. Function for filling tables (can be a database query or manual filling).
4. Creating a relationship between tables based on a common field.
5. Assigning a data source for the main DataGrid. For nested - in XAML.

The repository also contains a picture with a ready-made DataGrid and an example of XAML.

Advantages of using: Using this type of data display is especially useful in situations where you need to avoid repeating rows with the same information. Instead of having duplicate rows with the same data, all duplicate rows are combined into one, making the display cleaner and more readable.

DataSet Merging with DataTable

This project showcases how to merge two DataTables using DataSet. One table serves as the main table and the other as the nested one.

Key Steps:

1. Declare DataSet and DataTable.
2. Set up the DataSet structure and add tables with names.
3. A function to populate the tables (can be a database query or manual filling).
4. Establish a relationship between the tables based on a common field.
5. Assign data source to the main DataGrid. For the nested one, it's done in XAML.

The repository also features an image of the completed DataGrid and a XAML example.

Advantages of Using This Approach: Utilizing this kind of data representation is especially beneficial when looking to avoid repetitive rows with the same information. Instead of duplicating rows with identical data, all repeating rows are merged into one, making the display much cleaner and more readable.
