Rowupdating not working
I have a whole host of filters that do not work now since they rely on the auto postback feature in check boxes and drop down lists that I have. To String(), "ecylkows") = 1 Then i Col = i Chx 1 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. 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. Selected Then c = 1 If c = 1 Then str Params = "(Project Status = '" & Check Box List1. Text & "')" Else str Params &= " OR (Project Status = '" & Check Box List1. Text "" Then str Params = "(" & str Params & ") AND (ECADdesigner Names ='" & Me.
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?
Grid View has a method that is unfortunately protected called Extract Row Values.
I know its very annoying and hard to get the data out of the data controls (gridview in this case), but there are other things you can do to make it easier.
Then there are a couple more steps to make it to where you adding the selected value in the update) Yes, you are correct, I am not using any datasources for the gridview, but in the Itemtemplate and the Edit Item Template the Text parameter is set equal to a bind statement as follows (see the example further down where i ref a datasource for the ddl): Or in the case of the drop down list I am binding with the Selected Value parameter, but of course you can see I lied and am pointing to a different datasource completely for my list.
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.

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.
