Rowupdating get data dating someone out of a long term relationship
In this example, I am going to retrieve values from categories table of Northwind database. Drag a Grid View into the Web Form and assign Data Key Names property with the primary key column i.e. In the gdview_Row Editing and gdview_Row Deleting event, we have used the below code to retrieve categoryid from datakey of Grid View, int catid = int. The ig Grid™ control Updating feature includes three different interactions: updating, adding new rows, and deleting rows. The Updating feature can be turned on either for an individual cell (Cell Edit Mode) or an entire row (Row Edit Mode).The updating UI encompasses the built-in adding, updating, and deleting functionality of the grid including the add new button, add new row, editors, and edit and delete buttons.The start Edit method is used to put the grid into edit mode.Json String To Date Time method, because they are serialized using Microsoft format for serializing dates (Example: /Date(1356991200000)/).If auto Commit is not enabled (batch mode), the data source needs to be updated upon operations that rebind the grid such as paging, sorting or filtering.The save Changes method invokes an AJAX request posting to the update Url option (if specified) to the server.During the post, the grid passes the serialized transaction log as a JSON string as part of the POST.
By enabling the Updating feature, you enable adding, removing or updating the data in the grid.The auto Commit option value also affects aggregate Transactions option functionality.The aggregate Transactions option works on pending transactions (pending transactions are temporary transactions which are not yet committed to the underlying data source), which are available only when auto Commit is set to false.The ig Loader control is the recommended way to load Java Script and CSS resources required by the Ignite UI library controls.First the ig Loader script must be included in the page: When you initialize a new row on the grid for a data source that includes a primary key, the generate Primary Key Value event of ig Grid Updating feature is raised to provide a primary key value to the new row.
