Gridview rowupdating get cell value
I had a assignment I need to show only description and not ID. By using Datakeynames property you will get the selected row primary key.
[CODE] ID=”Grid View1″ runat=”server” Auto Generate Columns=”False” On Row Command=”Grid View1_Row Command” On Row Data Bound=”Grid View1_Row Data Bound” On Row Deleted=”Grid View1_Row Deleted” On Row Deleting=”Grid View1_Row Deleting” To get ID for selected row.
If we move our mouse on to the variables, which hold the cell values, we can see the old value instead of new updated value (Refer the debugging Screen Shot at the Top).
event is raised when a row's Update button is clicked, but before the Grid View control updates the row.
For example a Sql Data Source, which is automatically added to your Web Form if you drag-n-drop your way around Visual Studio 2005.
The problem is, I’d very much like to do so, if ASP. But I can’t set a Data Source property or anything on the Sql Data Source!!! I probably have to read the cells on the Grid View of the selected row, find the controls, get the values from those and insert those into my Data Set.
New Values("Location ID"); ok the the update worked when I assign a mock value..
This will lead to problems like "Grid View does not show updated values", "Grid View looses values changed by user". In your Page_load, this is typically only inside a block where you check to make sure that Page_Load is not being called during a post-back call.The event handler receives an argument of type Cell Value Changed Event Args containing data related to this event.The following Cell Value Changed Event Args properties provide information specific to this event.I am just wondering how to access the cell value for the row updating (event = Gridview. To String Message="Conversion from string "Location Name" to type 'Integer' is not valid." I would prefer to get the cells by name rather then by location e.g. Keys is an array of all the data keys you define for the gridview (Data Key Names="id", where "id" is the field name from your database query) e. Old Values are arrays of all the fields in the gridview data source that are NOT leys, where, as you might guess, e. This enables you to provide an event-handling method that performs a custom routine, such as canceling the update operation, whenever this event occurs.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.When we edit a row in our Grid View and press the “Update” button, at some time it’s received in the Row Updating method.But as I noted in the comments in that method, some collections that should contain the columns (names, old values and new values) are always empty. And the Row Updated method is never even touched!!! NET Forums that I need to use a Data Source control.Which means I won’t make my 70% code reduction Microsoft has always promised me. In this article I will share how to retrieve hidden value from Grid View Column.
