In this tutorial we are searching for our Text Box controls txt Product Name and txt Unit Price.
To get the Primary Key reference we can use the Data Keys collection of the Grid View.
By using the Grid View Row object we can find the reference of any control in the row in which user is editing the data.
I'd like to know if there are any other ways to retrieve the new values? I have been using the web site successfully for just over a year, and I am presently using a Select button in the row to launch a detailsview, and I edit the database that way. Net a year and a half ago, and VB programmer forever before that, but I feel pretty confident in this large and powerful website I have created, but the users don't like the details view have expressed a desire to edit on the fly in the gridview. My user base has a hold of management's ear, and my management wants to dump ASP. This could be the straw that broke the camel's back - a person's job hangs in the balance - MINE!! If you are databinding in page_load then you need to only do it if(!
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?
Place Link Button Edit in Item Template and Link Button Update and Cancel in Edit Tamplate of Gridview's column. Fire Grid View's Row Editing event for Link Button Edit. Fire Grid View's Row Updating event for Link Button Update. Fire Grid View's Row Canceling Edit event for Link Button Cancel. Set Command Name propery of Link Buttons according to their respective event. Set Grid View's Data Key Names Property to record ID (ID=Primary/Unique key of student table) 7.
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.
