    Updating database from datagrid best pinoy dating site

    Abstract: I was recently working on a requirement to perform Update and Delete operations on a WPF Data Grid control (similar to what developers do in a ASP. The WPF Data Grid is an excellent control to bind with collections and provides various events to work with. Now since Salary and Dept No can be updated, on the click event of the ‘Update’ button, the following code is written.

    I was recently working on a requirement to perform Update and Delete operations on a WPF Data Grid control (similar to what developers do in a ASP. The WPF Data Grid is an excellent control to bind with collections and provides various events to work with. This code changes the columns for ‘Salary’ and ‘Dept No’ in edit mode.

    After the completion of the wizard, the following model will be generated: In the XAML, the Data Grid columns are made read only using ‘Is Read Only’ property set to false.

    Save Changes(); INSERT records by moving to the next/prior row: Ok, this is a little more complicated because you need to make sure the user is inserting a record.

    Microsoft has made the update operation very simple to accomplish, however, the insert and delete are not that simple.

    I’m sure there are other ways to accomplish these tasks, however, this is how I made it work…. You might need to add a reference to the ENTITY FRAMEWORK by right clicking on references, manage Nu Get packages and find ENTITY FRAMEWORK. Copy the following code to the Main Window.xaml: A little explanation: UPDATE records by moving to the next/prior row: The update operation is automatic as long as you have the Binding=”” in every column.

    The way the architecture works with the Data Adapter is that you can make any changes you want to the filled Data Set, and it won't affect the database until you call the Update method.

    When Update is called, the Data Adapter will attempt to execute each query (UPDATE, INSERT, DELETE) on every row of the Data Set that has been updated, inserted, and deleted.
