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. The key fields are defined in the Data Key Names property of a Grid View control.But for this demo, I’ll show you the simple version, that also doesn’t work 🙂Let’s bind the data to our Grid View and have it autogenerate our columns, as well as an edit button.
Time Entry Date between dateadd(dd, -6, @Week Ending) and @Week Ending) AND TE.
event returns this output: event args: (command=System.
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.
For a while now I’m trying to figure out why my method, triggered by the Grid View.
the good old problem of getting the data from the row that is being currently edited within a Grid View. Accessing the "Controls": This method gets you access to the control in the Grid View, which might be useful based on what you are doing.
Obviously the simplest method is to use Data Key Names on the Grid View and then you should have the data in your Grid View Update Event Args as part of e. (In the following example, I cast to a Check Box as I know I have a checkbox at the col Index You Are Interested In - you should cast to whatever control you have in that column).
As the values are inserted into an Ordered Dictionary - you can use the field names to access the changed data 2.
There are multiple ways in which one can get the data from the current row that is being edited in a Grid View. Using "Extract Values From Cell": This is an easy way to get all the values from the current row.
It examines the command object and, if it is the same referenced object, it essentially rebuilds the object, thereby destroying your command text changes.
One approach to solving this problem is to clone the command object so you have a different actual reference: This will work, but since the Command Builder is still connected to the Data Adapter, the Row Updating event will still fire and performance will be hit.
event is raised when a row's Update button is clicked, but before the Grid View control updates the row.
