Master/Detail relationship in VB.NET
Not what you're looking for?
Using VB.NET For this project, you will use the following database schema, which has two tables.
The input form contains a ListBox and a DataGrid control. Select asset categories in the list box and then the corresponding asset information will appear in the DataGrid. As you select different categories, the total costs are recalculated for the selected category and displayed in a label on your form, formatted as currency.
Configure the form so it appears on the center of the desktop when the solution is run.
Do not allow the user to resize the form.
Remove minimize, maximize, and close buttons from the title bar.
Perform the appropriate steps to create a connection to the sample database. Be sure to select the option to copy the database to your project so it will be automatically included in the project.
Create an instance of the ListBox control. Set the necessary properties so the ListBox control will display the field fldCategoryDesc.
Create an instance of the DataGrid control on the form. Configure the DataGrid control instance so it displays records from the table named tblAssets, but only for those records matching the selected category shown in the list box.
Format the DataGrid so the column header names are the same as the ones shown in the Figure. Set appropriate column widths, and format the cost column as currency, right justified. The date column should also be right justified.
Write the necessary code to calculate the total cost of the displayed assets. Display the results in a Label control above the cost column of the DataGrid. Format the output as currency. Right-justify the output in the Label control instance.
Create an Update button that will allow the user to save any changes made to the DataGrid back to the database. Write the necessary code for the button. Allow the user to add, change, and delete records in the Asset table.
Create an Exit button for the solution. In the Click event handler for the button, display a message box to get confirmation from the user before exiting the solution.
