Gridview rowupdating e newvalues null
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? 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. Selected = True Else End If Fill Grid View() End Sub Private Sub Fill Grid View() Dim i Col As Integer, c As Integer = 0, i Chx As Integer, i As Integer Dim str SQL As New System. String Builder Dim str Params As String = "" 'THE FOLLOWING CODE THAT INDICATES SPECIFIC COLUMN NUMBERS IS DETERMINED 'BY THE HTML ASPX CODE THAT DETERMINES HOW THE GRIDVIEW LOOKS For i Chx = 0 To Me. Did I mention I am getting bored of grids, data and databases and am going to spend the holiday break convincing myself I can learn to be a game programmer... (i.e., employee ID: you can convert an emp ID field in your gridview to a templatefield then delete the label in the edit Item Template then insert a dropdownlist then bind the dropdownlist to a datasource that binds you're to your employee table in your database. Am I being clear, or am I being presumtuous in my undertsnading of the use of datasources? *I believe your asking us if you're precluded from binding a dropdownlist (for example) to a datasource from within a templatefield in your gridview, and if thats what your asking... And all I'm saying is that you YES can use another datasource. Text "" Then str Params = "(" & str Params & ") AND (ECADdesigner Names ='" & Me.
This is not necessarily a bad thing, we can still get all the functionality you can get from going from the codebehind. ♦ I prefer to use linq, but the fact is that when your using controls like the Grid View or Detials View etc..
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.
