Rowupdating keys

07-Sep-2020 13:08

But as I noted in the comments in that method, some collections that should contain the columns (names, old values and new values) are always empty. And the Row Updated method is never even touched!!! NET Forums that I need to use a Data Source control.

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 hash key is the key of corresponding column and the value is the new value to be set.

Please help me with writing a Row Updating function in C#, I don't know how to grab the current field's value and also get the old value for one of keys (which is Project Name for editing) of the selected row. the idea wa to don't allow binding the grid view after a post back. Count ----------- The most common problem for losing new data entered while updating a Grid View or Data Grid is that you are resetting the Data Source for the Grid View or Data Grid in the Page_Load method. I actually don't know how to write the Row Updating function, I just found it from the internet, and so of course it's not working.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. Row Updating event, doesn’t work as all samples say it should do.

All samples of course assume you’re doing everything in your page, but I have to do everything in my code-behind, because on forehand I don’t know what I’ll be binding to my Grid View.Chat with people who are looking to meet up for friendship, dating or more, just like you.
