I have a window application. In one of the form, a datagrid has a dataview
as its datasource. Initial filtering result would give the datavew 3 items.
When I double click on the datagrid to edit the selected lie item at which
case I would pop up a separate dialog box to do so, in the debugging code,
the dataview.count would return 0. I get a error message because I tried to
get values out of a dataview that holds 0 items. Does anyone...

Dear friends
Dim myDataView as DataView = New DataView(dsData.Tables("tblCustomers"))
myDataView.RowFilter = "City = 'London'"
My question is how to loop through all rows in myDataView and edit the field
fldZipCode so fldZipCode = "9800"

Hi all,
I edit records using a form that have multiple control bind on Dataview, But
I don't want to update right always to database, I would like to delay until
all Changes (add all new record using a form or edit various existing
records)
This way I could minimize transaction on server..

I have an application that displays data in a DataGridView. The data is in
a DataView that is sorted and at times filtered. One of the columns I have
in the dataview is a boolean field called "selected". Typically the
DataView will either be sorted or filtered by this column. However when the
user toggles the row value for this column (and others as well) in the
DataGridView and ends the edit the data in the dataview changes, causing...

What is the real difference between the DataView and the DataGridView?
Is the DataView even a control or is it merely a class? With methods
that allow you to edit rows and columns it seems like it would be a
control that you could drag and drop on a form in the designer but I
cannot find the DataView control in the toolbox. I have used a
DataGridView before but I was wondering if DataView has better
functionality.
Thanks!

I've been searching online for a while now with no luck, so I'll try the friendly folk here.
_The Problem
I have a dataset/dataview that's getting its data from an XML file (which we're using sort-of like a database). I'm a little more used to contacting SQL servers instead of XML files, but have managed to read from the XML file and read/display the data. I thought I was able to change the data (from a form) as well, but realized the...

I have a dataset with 3 tables -- 2 Parent tables and 1 table that is a child
table of both the parents. I create a dataview on the child table and set
the rowfilter to a value which filters the child based on values in both
parent tables. When I edit the parent tables the edit is not reflected in
the dataview.count property. How can I force the dataview to refresh
following parent table edits?
For example:
