Updating customer records forms dating in wooster
Because a majority of Web applications involve reading data and not updating it, one-way data binding keeps the size and complexity of the page architecture to a minimum for the most common scenarios.
However, there are times when you do want to update data. If you are using a dataset, you can write changes to the dataset and then call the data adapter to send changes from the dataset to the database.
(For an example of this scenario, see Walkthrough: Using a Data Grid Web Control to Read and Write Data.) Alternatively, you can update the database directly, using SQL statements or stored procedures, which is what this walkthrough illustrates.
This walkthrough illustrates how to create a Web Forms page that reads and writes data to a database using SQL statements. Close() End Sub // C# private void ddl Category ID_Selected Index Changed(object sender, System.
You will set the following properties: These properties receive the name of the method that handles the corresponding operation.
In these situations, you'll want to set up and use a multitable form for data entry.
For example, Figure A shows a multitable form included with Access' sample Northwind database.
When you run Statistics History Update, the system accumulates amounts for the Minor Write-Off (MWO) and Bad Debt (BDBT) fields in the A/R Statistical History (F03B16) and A/R Statistical Summary (F03B16S) tables.
The system determines the write-off amount with which to update each of these fields based on the value of the Special Handling field in user-defined code (UDC) 03B/RC: As part of the customer analysis activities, you can update statistical information about customer accounts by running the Statistics History Update program.
If you didn't use a multitable form, you'd have to display a different screen for each combination of company name, order, and order detail.
