Get datakey value gridview rowupdating
Delete a Record We can delete a record from the database table by clicking on the delete button that is in the Delete column of the Grid View.
We first of all create a Stored Procedure that gets the Id of an employee as a parameter from the Grid View on whichever row the user clicked. In this event, first we get the datakey value that is the id of an employee of whichever row the user clicked and that id is passed as a parameter to the Stored Procedure. According to the above, in these three operations we use three events of the Grid View for each operation.
When a Grid View row is in edit mode then we can update the row's record in the relational database table.
So we need to create a Stored Procedure on which we pass all parameters that are updateable along with the primary key value, in other words the row data's key value that is being updated.
In this article I will share how to retrieve hidden value from Grid View Column.
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.
We can't update a record until that record doesn't exist in the input type field (Text Box).
So first we need to move to an updateable row record in the Text Box.
We get the Id value using the row index and another Text Box value is also retrieved.
New Values("Location ID"); ok the the update worked when I assign a mock value..
Text could not avoid the cell numbering :/ somehow select Row.
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.
