Rowupdating event in c
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.
Grid View has a method that is unfortunately protected called Extract Row Values.
Append("SELECT Project ID, Pcb Pn, Pcb Pn Rev, Change Number, Design Names, ECADdesigner Names, Pwb Engineer Names, Pwb Request Date, ECADstart Date, Due Date, Project Status, Job Charge Number, Percent Complete, Completion Date, Actual Start Date, Schematic Number, Schem Num Revision, Schem Ready Date, Layer Count, PCBtechnology, Stack Up, Thickness, Lead Free, Requester Comments, Product Manager") str SQL. Append(" WHERE" & str Params & " ORDER BY Due Date ASC") 'This is a subtitute for Private Sub Populate Publishers Grid View() from example code 'found at View Sorting Dim str My Conn As String = Configuration Manager.
Selected Value Case 8 str Params = "(" & str Params & ") AND ((" & _ "(Right(Completion Date,4) '2005'))" & _ "OR (Completion Date is NULL))" Case 7 str Params = "(" & str Params & ") AND (Right(Completion Date,4) = '2007')" Case 6 str Params = "(" & str Params & ") AND (Right(Completion Date,4) = '2006')" Case 5 str Params = "(" & str Params & ") AND (Right(Completion Date,4) = '2005')" End Select str SQL.
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.
Visible = True Catch ex As Exception Track Projects. Close() End Using Hi Lite Rows() End Sub Private Sub Hi Lite Rows() 'THE FOLLOWING CODE THAT INDICATES SPECIFIC COLUMN NUMBERS IS DETERMINED 'BY THE HTML ASPX CODE THAT DETERMINES HOW THE GRIDVIEW LOOKS Dim i Col Date As Integer = 7, i Row As Integer, i Col Proj Stat As Integer = 9 ' Msg Box(Track Projects.
To String) ' & vb Cr Lf & vb Cr Lf 'Val(CDate(Track Projects.
Edit Index Then i Row = 1 If i Row = Track Projects. Count Then Exit For lbl Text = Direct Cast(gv Track Projects. I've attached my code for what it's worth, but it will probably be too dificult to determine everything that I am doing. Is there a flag I can turn on or off when I am doing row updating so that I can detect and not rebind? I think my question was more to the point, if I have a datasource then I have to have boundfields, and this would preclude use of template fields? you're not using a single datasource in your templatefields. Because as you can see from the html I posted, I am using boundfields and template fields in the same gridview, and I am reading and writing.
