A Grid View Edit Event Args object is passed to the event-handling method, which enables you to determine the index of the current row and to indicate that the edit operation should be canceled.event is raised when a row's Update button is clicked, but before the Grid View control updates the row. This dictionary contains all fields in the row except the key fields. Time Entry Duration Hours FROM dbo.aspnet_starterkits_Time Entry TE inner join dbo.aspnet_starterkits_Project Categories CAT on TE. Category ID inner join dbo.aspnet_starterkits_Projects P on CAT. Time Entry User ID=(SELECT User Id FROM dbo.aspnet_Users WHERE User [email protected] Name)) Source pivot (max(Hours)for DOW in (,,,,,,) ) as pvt" Old Values Parameter Format String="original_" Use the Old Values property (dictionary) to access the original values of the fields in the row to update.For example you could have the following code:to store the information. Finally the code is bound to the When the user selects a record from the grid, the selected row index will be passed through as the Command Argument.Run the project and place a breakpoint on the code above. The program will stop on the breakpoint and you will be able to see the selected row index being passed through.This example won’t hook into a database, but we will create a class to mock a table and retrieve data from it instead. This enables you to not display the ID to the user, yet still being able to retrieve it.You can also assign multiple primary keys if desired by separating them with a comma (,). This allows you to create a new instance of a class and assign values to properties in one easy step.
A Grid View Update Event Args object is passed to the event-handling method, which enables you to determine the index of the current row and to indicate that the update operation should be canceled. A datakey represents the primary key field or field of a record that can uniquely identify it in a data-bound control. Row Index represents the index of the particular row.Many a times in our applications we use primary keys to get control of the particular record in the gridview. Raises the Page Index Changing and Page Index Changed events.event is raised when a button listed in the previous table is clicked, it is recommended that you use the events listed in the table for the operation.I'm using a sqldatasource control to populate the grid and want to write the update code in the Row Updating event. I can get the value of the first field using " Select Command="SELECT @Week Ending Week Ending , Project , Project ID , Category , Category ID ,isnull(, 0) Sun ,isnull(, 0) Mon ,isnull(, 0) Tue ,isnull(, 0) Wed ,isnull(, 0) Thu ,isnull(, 0) Fri ,isnull(, 0) Sat from (select P.
