Rowupdating current 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.
We will use Template Field, whenever we want to define some custom control in the data bound controls like Grid View, Data Grid or Data Repeater.
If he clicks edit (or) in the edit mode he can be able to see the Textbox.
There must be something fundamentally wrong that some of us are doing that is causing this and the fact that it's not happening to others, and they don't know the solution. this only works when the databind happends after the updating. My suggestion to you would be to either subclass gridview, and expose the Extract Row Values though a public method or stick everything you need in Data Keynames. Extract Values From Cell(dict Values, dcfc Cell, gv Row. Row State, True) End If Next control Dim return Values = New Dictionary (Of String, Object )() For Each de As Dictionary Entry In values return Values(CStr(de. Value Next de Return return Values End Function I appreciate your quick and prompt reply, which I looked at from home last night, but was not able to test it until just now, and really the only different was adding the Try Cast. You're trying to extract the values from the edit row right?
It'd be great if you could provide some sample code here. I am using the Row Updating event to programmatically update my database, but the new values are already gone by the time the Row Updating event is fired. I have found several forum postings detailing this but no one has posted their solution. Another way to get values out of the gridview is to put the interesting fields in Data Key Names, which can be a very ugly solution because the viewstate grows as a result of this.
In case of the bound field’s we need to check what column it is and need to use index of that cloumn, which is little hard and even in future if we change the column order If you see the Last Template Field part in the above code, I am using the link buttons for edit, update, delete and cancel.I have a dynamically created gridview, it's autogeneratedcolumns is set to True, and it databinds on every postback. If i move the databind to load (which fires before the Row Updating) it ceases to work correctly, and the newvalues are null. Dim o Conn as new Sql Connection("") Dim o Cmd as new Sql Command("Update Sp", o Conn) o Cmd. Guys maybe it's just Friday evening and I've already had 1 Guinness to ease the tension, but you two just flew about 30,000 feet over my head. Crack open reflector and look at the Grid View's source code. The event arguments will ALWAYS be empty unless you are bound to a datasource control. created the following code in VB, and though it runs without error, it's not doing anything for me. This is such a monumental show stopper after all the work I have put into this web site, I can't believe there isn't a straight forward method of retrieving the new values. Edit Index) Dim dict Values As New Ordered Dictionary Dim o Ctl As Control For Each o Ctl In gv Row. Row State, False) End If Next Dim dict Entry As Dictionary Entry For Each dict Entry In dict Values Try Msg Box(dict Entry. To String) Catch ex As Exception End Try Next Public Shared Function Get Values(row As Grid View Row) As IDictionary (Of String, Object ) Dim values = New Ordered Dictionary() For Each control As Control In row. Unfortunately I am getting identical results...same I have always been getting which is just the old values. Try to write a small sample with one column and that one event and see if it works. 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. The row which the cursor is positioned on is locked, however once it moves to another row, the lock may be released depending on transaction isolation level.
This means that rows in the scrollable insensitive result set may have been updated/deleted by other transactions after they were fetched. 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.
