Net gridview rowupdating event
Is there a flag I can turn on or off when I am doing row updating so that I can detect and not rebind?
Protected Sub Page_Load(By Val sender As Object, By Val e As System. Load Dim i Col As Integer, c As Integer = 0, i Chx As Integer 'If In Str(Http Context.
If you do this, your Grid View's source will be refreshed before you're able to grab the new values out of it.
I'm having a very hard time understand what would prevent your event from being fired.
Edit, True) obj Sql Param = New Sql Parameter("@New Expired ID", Sql Db Type.
New Values("Property ID_Expired") 'The parameter is case sensitive.
If so, how do you know the control id if it's dynamically created? I am having the same problem, and it's not a boundfield or template field problem either as I am using both. This magical function extracts values from the datacontrol fields and puts them in an IOrdered Dictionay.
Now, when an user edit a row then click update, I'm having problem getting the new values in gridview's rowupdating event, it always returns the old values. With that being said you could go directly after the form post data perhaps, i usually find it's easiest to debug then search through and find your key value pair. I'll take a closer look at your posts maybe tomorrow, and definitely Monday, but I'm just a hack, and I so close to dumping this whole thing and lettting someone else do it...whooops there isn't anyone else... The new values are not being retrieved, just the old values. Excuse my crude Msg Box methos; it only goes to prove what a hack I am. Controls Dim dcfc Cell As Data Control Field Cell = o Ctl If dcfc Cell Is DBNull. Controls Dim cell As Data Control Field Cell = Try Cast(control, Data Control Field Cell) If cell Is Not Nothing And Also cell. By the way, when I attempted to cut and paste your code, the compiler would not accept the arguments (String, Object) at the end of IDictionary, saying that IDictionary has no parameters, and also in the return values portion below it complains that Dictionary is not a type. Dictionary is a generic type and you have to include System. I'm not sure whats going on in your case Yes I am getting the exact data that's in the edit row. It's a record that looks similar to the other data in the database, but it is defintiely different values so I am confident that I am looking at the edit row.
I believe that databinding on every postback is the cause but that's not something that I can change right now, same goes with the autogeneratedcolumns setting. I'm not sure if I know what you mean about 2 way binding. If you meanam I using Bind instead of Eval in my HTML, then yes. And the result of your code is no different than my version or what I was doing before, which was just using the findcontrol method, and that just returns what was in the grid when it was first binded to the database on page load. Yes ok i think i know what you are probably doing wrong.
The reason is we don't fill the values unless your are bound to a datasource control.
Data Bind() End Sub Its not your fault that the new values are empty.
